There is no memory leak problem with Java storage

There is no memory leak in the Java store. We first need to understand what a memory leak is. Memory leaks in Java in short, the object is used up, and the memory space occupied by the object is not released until the program finishes running .

So now it's the problem! Don't we say Java has a good garbage collection mechanism? Why is there still a memory leak? At this point we need to understand the mechanism of the GC. when the program is running, the heap memory space object is not referenced, the heap memory space belongs to the garbage space , should wait for GC recycle, this is no problem. But then! There is also the case that when the heap memory space is referenced by other objects (as an object of a) , even if the object of the heap memory space is released by itself, if the A object does not release a reference to it, the GC cannot be reclaimed, so there is a memory leak.

If it is not correct, look at it. Thank you
