Off 1. The meaning of garbage collectionIn C + +, the memory occupied by an object is occupied until the end of the program and cannot be assigned to other objects until it is explicitly released, whereas in Java the memory becomes garbage when there is no object reference to the memory originally assigned to an object. A system-level thread of the JVM automatically frees the block of memory.

From: http://tech.qq.com/a/20060726/000329.htm The Java heap is a runtime data zone, and the instance (object) of the class allocates space from it. The Java Virtual Machine (JVM) Heap stores all objects created by running applications. These objects are created through commands such as new, newarray, anewarray, and multianewarray, however, they do not need program code to be explicitly released. In general, the heap is responsible for garbage collect

The working principle of the Java garbage collection mechanism. Java's heap is a run-time data area in which instances (objects) of the class allocate space. The Java Virtual machine (JVM) heap stores all objects that are established by the running application, which are established through directives such as new, NewArray, Anewarray, and Multianewarray, but they do not require program code to be released explicitly.

Objective In the C + + language, programmers must handle every memory allocation with care, and must manually release the memory space that has been occupied after the memory is used. A memory leak problem occurs when the memory is not fully released, that is, the allocated, but never-freed, block. In the Java language, it gives programmers a good promise: programmers don't need to manage memory because the JVM has GC to automate garbage collec
