In the JVM, memory is divided into two parts, stack (stack) and heap (heap), where we know the stack and heap from the perspective of the memory management principle of the JVM, and these principles recognize the problem of static and static properties in Java.In general, the JVM's memory is divided into two parts: Stack and heap. (both stack and heap are in RAM)The stack (stack) is the memory instruction area of the JVM. Stack
zone becomes the new to zone and the to zone becomes the new from zone.If the minor collection is found to be out of the area, then part of the object is put into the mature generation. On the other hand, even if the to area is not full, the JVM will still move long enough to mature generations.If the mature generation fills the object and cannot move into the new object, the major collection is triggered. The JVM uses the mark and sweep strategy for garbage collection of mature generations.Sum
A good Java programmer must understand how the GC works, how to optimize the performance of the GC, and how to interact with the GC in a limited way, because some applications have higher performance requirements, such as embedded systems, real-time systems, and so on, to improve the performance of the entire application only by improving the efficiency of memory management.
