, understanding the memory recovery mechanism of a virtual machine, we don't rely too much on it, but explicitly "free up memory" when needed (Java code cannot explicitly release memory, but you can tell the garbage collector to recycle the object by releasing the object reference). To reduce unnecessary memory consumption; If we understand how the Java stack works, then we can reduce the risk of stack over
