Abstract

The invention discloses a Java object reference method, Java object reference devices and a medium, which are used for solving the program crash problem due to that strong references cannot be automatically released and cause excessive occupied memories. The Java object reference method includes: when an intermediate variable object receives a reference request of requesting a reference of a second variable object by a first variable object, utilizing the intermediate variable object to invoke the second variable object according to the reference request, wherein the intermediate variable object is defined for the first variable object and the second variable object of which a strong-reference relationship exists; for the intermediate variable object, monitoring whether a preset releasingcondition is met; and invoking a releasing function to release the intermediate variable object when the preset releasing condition is met.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a Java object reference method, device and medium. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Java object references include strong references, soft references, weak references, and phantom references. Among them, a strong reference refers to creating an object and assigning the object to a reference variable; a strong reference will never be garbage collected when it is pointed to by a reference variable. When the memory space is insufficient, the Java virtual machine would rather throw an Out Of Memory Error (memory overflow) error to cause the program to terminate abnormally, and will not arbitrarily recycle objects with strong references to solve the proble...
