[0071] Figure 5 is the schematic structural diagram of the electronic device provided by the present invention. Detailed Embodiments

[0072] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0073] The following will, in conjunction with the drawings, elaborate on the technical solutions provided by each embodiment of the present invention.

[0074] First, the noun terms mentioned in the embodiments of the present invention will be explained.

[0075] Countdown object: An entity that associates the graphical interface with the countdown logic. When the countdown time changes or the countdown ends normally, the user is notified through the countdown object.

[0076] Countdown time: A time number in seconds.

[0077] Countdown task: A logical entity within the system that establishes the countdown time and maintains key-value pairs for each countdown object.

[0078] Thread pool: used to manage multiple threads. A large number of idle threads are created when the system starts. When a task is received from the program, an idle thread is started to execute this task. After the task is executed, the thread does not die but returns to the thread pool and is set to the idle state, continuing to wait for the next task to be executed.

[0079] Figure 1 It is a schematic flowchart of the countdown method provided by the present invention, as Figure 1 shown, the method includes:

[0080] Step 110, obtain a countdown object and a countdown time, generate a first key-value pair based on the countdown object and the countdown time, and display the countdown time.

[0081] Specifically, obtain a countdown object and a countdown time. Among them, the countdown object is an entity that associates the graphical interface with the countdown logic. When the countdown time changes or the countdown ends normally, the user is notified through the countdown object. The present invention can use the countdown object to immediately notify the user of the current countdown time at the start of the countdown. For example, when the user sets a countdown of 120 seconds, the prior art can only notify "119" after one second, while the present invention can immediately notify the user of the number "120", meeting the user's need to immediately obtain the current countdown time.

[0082] Step 120, create a corresponding countdown task according to the countdown object, and generate a second key-value pair based on the countdown object and the countdown task.

[0083] It should be noted that generating two types of key-value pairs, namely countdown object - countdown time and countdown object - countdown task, not only ensures the uniqueness of the countdown task but also greatly increases the throughput of the entire system and can be applicable to scenarios of multi-task parallelism.

[0084] Step 130, call the thread pool to obtain the countdown task within a set time period, and execute the countdown task according to the first key-value pair and the second key-value pair to update the countdown time and display it.

[0085] Among them, the thread pool is used to manage multiple threads to obtain and execute countdown tasks. Since the system continuously starts and shuts down threads during multi-threaded operation, the system resources are over-consumed and may cause the collapse of system resources. Using a thread pool can avoid such problems, conveniently manage threads, reduce resource consumption, and thus improve system performance. The existing timer Timer only creates one thread when executing a timed task. If there are multiple tasks and the task time is too long and exceeds the interval time between two tasks, unpredictable problems such as timing confusion will occur. The present invention uses a thread pool to execute countdown tasks, overcomes the defects of Timer, and achieves the effect of isolating tasks from each other and releasing the resources occupied by the mobile phone system when idle.

[0086] The countdown method provided by the present invention generates key-value pairs of a countdown object and a countdown time, and a countdown object and a countdown task, calls a thread pool to obtain a countdown task within a set time period, and executes the countdown task according to the two types of key-value pairs to update the countdown time and display it. There is no need to repeatedly call the system time during the countdown, which solves the problem that the timer is affected by the change of the system time and causes inaccurate timing.

[0087] Further, generating the first key-value pair based on the countdown object and the countdown time includes: using the countdown object as the key of the first key-value pair and the countdown time as the value of the first key-value pair; generating the second key-value pair based on the countdown object and the countdown task includes: using the countdown object as the key of the second key-value pair and the countdown task as the value of the second key-value pair.

[0088] Based on the above embodiments, the present invention uses ConcurrentHashMap to cache and store the first key-value pair and the second key-value pair. Among them, ConcurrentHashMap is a thread-safe and highly concurrent version of HashMap. It is a concurrent container composed of an array and a linked list, and can support 16 threads to execute concurrent write operations and any number of threads to execute read operations. When the thread pool executes the countdown task, it needs to access the first cache and the second cache based on ConcurrentHashMap multiple times to update the countdown time. ConcurrentHashMap can ensure the efficient concurrent execution of multiple tasks.

[0089] Specifically, after generating the first key-value pair based on the countdown object and the countdown time, it is also necessary to determine whether the first cache exists; if the first cache for storing the first key-value pair exists, write the first key-value pair into the first cache; if the first cache for storing the first key-value pair does not exist, create the first cache and write the first key-value pair into the first cache. Similarly, for the second key-value pair, it is also necessary to determine whether the second cache exists; if the second cache for storing the second key-value pair exists, write the second key-value pair into the second cache; if the second cache for storing the second key-value pair does not exist, create the second cache and write the second key-value pair into the second cache.

[0090] The present invention stores two types of key-value pairs in concurrent caches respectively, which can support multiple threads in the thread pool to concurrently access the first key-value pair and the second key-value pair, execute the countdown task to update the countdown time, so as to efficiently perform countdown processing.

[0091] Based on the above embodiments, as Figure 2 shown, step 130 further includes:

[0092] Step 210, calling the thread pool to obtain the countdown task from the second cache within a set time period.

[0093] Specifically, for example, if the set time period is one second, the thread pool performs an operation once every second to obtain the countdown task from the second cache.

[0094] Step 220, based on the first key-value pair and the second key-value pair, execute the countdown task to perform countdown processing on the current countdown time to obtain the updated countdown time.

[0095] Specifically, change the current countdown time according to the set time period. For example, if the set time period is one second, change the current countdown time from i to i - 1.

[0096] Step 230, determine whether the updated countdown time in the first key-value pair reaches the set time threshold. If it reaches the set time threshold, execute step 240; if it does not reach the set time threshold, execute step 250.

[0097] Among them, the value of the set time threshold is 0.

[0098] Step 240, terminate the call to the thread pool to obtain the countdown task, remove the first key-value pair and the second key-value pair from the first cache and the second cache respectively, and display the end of the countdown through the countdown object.

[0099] Specifically, if the countdown time is reduced to 0, it indicates that the current countdown has ended. It is necessary to notify the thread pool to stop obtaining countdown tasks, remove the corresponding first key-value pair and second key-value pair from the first cache and the second cache based on ConcurrentHashMap, and notify the user that the countdown has ended through the countdown object.

[0100] Step 250: Display the updated countdown time through the countdown object, and continue to execute the step of performing countdown processing on the updated countdown time for the countdown task.

[0101] Specifically, if the countdown time is not reduced to 0, display the updated countdown time i - 1 through the countdown object, and continue to repeat the above countdown processing steps for the countdown time i - 1.

[0102] The following is an example to illustrate the above countdown process. For example, the countdown time starts from 10 seconds, the set time period is 1 second, and the time threshold is 0. Execute the countdown task to change the current countdown time to 9 and display it through the countdown object, continue to update the countdown time to 8 until the countdown time is updated to 0, then terminate the current countdown task and notify the user that the countdown has ended.

[0103] The present invention encapsulates a series of operations for calling the thread pool to execute the countdown task, eliminating the need for the caller to repeatedly write code logic such as time counting, achieving the purpose of streamlining the code.

[0104] Based on the above embodiments, as Figure 3 shown, step 210 specifically includes:

[0105] Step 310: Determine the countdown object corresponding to the countdown task based on the second key-value pair.

[0106] Step 320: Obtain the corresponding first key-value pair from the first cache based on the countdown object.

[0107] Step 330: Determine the countdown time corresponding to the countdown object based on the first key-value pair.

[0108] Specifically, the thread pool obtains the countdown task from the second buffer, associates the first key-value pair in the first cache with the current second key-value pair based on the countdown object, and thus obtains the countdown time corresponding to the current countdown task.

[0109] Step 340: Obtain the current countdown time in the first key-value pair, execute the countdown task to perform countdown processing on the current countdown time, and write the countdown time after countdown processing as the updated countdown time into the first key-value pair.

[0110] Specifically, change the current countdown time according to the set time period. For example, if the set time period is one second, change the current countdown time from i to i - 1.

[0111] Based on the above embodiments, after obtaining the corresponding first key-value pair from the first cache based on the countdown object, if the first key-value pair does not exist in the first cache, terminate the call to the thread pool to obtain the countdown task, and remove the second key-value pair from the second cache.

[0112] In summary, the countdown method provided by the present invention generates key-value pairs of a countdown object and a countdown time, and a countdown object and a countdown task, calls a thread pool to obtain a countdown task within a set time period, and executes the countdown task according to the two types of key-value pairs to update the countdown time and display it. It is not necessary to repeatedly call the system time during the countdown, solving the problem that the timer is affected by the change of the system time, resulting in inaccurate timing.

[0113] At the same time, storing the two types of key-value pairs in a concurrent cache respectively can support multiple threads in the thread pool to concurrently access the first key-value pair and the second key-value pair, execute the countdown task to update the countdown time, and thus perform countdown processing efficiently.

[0114] In addition, a series of encapsulations are performed on the operation of calling the thread pool to execute the countdown task, eliminating the need for the caller to repeatedly write code logic such as time counting, achieving the purpose of streamlining the code.

[0115] Next, the countdown device provided by the present invention will be described. The countdown device described below can be correspondingly referred to the countdown method described above.

[0130] Judge whether a second cache for storing the second key-value pair exists;

[0131] If there is a second cache for storing the second key-value pair, write the second key-value pair into the second cache;

[0132] If there is no second cache for storing the second key-value pair, create the second cache and write the second key-value pair into the second cache.

[0139] If the set time threshold is not reached, display the updated countdown time through the countdown object, and continue to execute the step of performing countdown processing on the updated countdown time for the countdown task.

[0140] The present invention encapsulates a series of operations for invoking the thread pool to execute the countdown task, eliminating the need for the caller to repeatedly write code logic such as time counting, achieving the purpose of streamlining the code.

[0147] If the first key-value pair does not exist in the first cache, terminate the invocation of the thread pool to obtain the countdown task, and remove the second key-value pair from the second cache.

[0148] In summary, the countdown device provided by the present invention generates key-value pairs of a countdown object and a countdown time, and a countdown object and a countdown task, calls a thread pool to obtain the countdown task within a set time period, and executes the countdown task according to the two types of key-value pairs to update the countdown time and display it. It is not necessary to repeatedly call the system time during the countdown, solving the problem that the timer is affected by the change of the system time, resulting in inaccurate timing.

[0149] At the same time, the two types of key-value pairs are respectively stored in a concurrent cache, which can support multiple threads in the thread pool to concurrently access the first key-value pair and the second key-value pair, execute the countdown task to update the countdown time, and thus perform countdown processing efficiently.

[0150] In addition, a series of encapsulations are performed on the operation of calling the thread pool to execute the countdown task, eliminating the need for the caller to repeatedly write code logic such as time counting, achieving the purpose of streamlining the code.

[0152] In addition, when the logical instructions in the above-mentioned memory 830 are implemented in the form of software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium. Based on such an understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product.
