Between Java and C + + there is a "high wall" of dynamic memory allocation and garbage collection technology, and people outside the walls want to go in, but the walls are coming out.

Java memory allocation and management is one of the core technologies of Java, before we have described the Java memory management and memory leaks and Java garbage collection knowledge, today we dive into the Java core, a detailed description of Java in memory

adjusted.After the class loader reads the class file, it is necessary to put the class, method, and constant variables into the heap memory to facilitate execution by the executor. In general, the memory allocation of objects is done on the heap.In the course of running a Java program, a large number of objects are ge

heap memory. The program will first determine the size of memory allocated in the heap, then call operator new to allocate the memory, then return the first address of the memory, and put it into the stack, the assembly code in v

, memory, and registers. So when learning about the Java memory allocation principle, it is important to keep in mind that all this is done in the JVM, which is the basis and premise of the memory allocation principle.In a nutshell, a complete Java program will run with the

instructions and uses a different storage area. It is responsible for executing instructions, managing data, memory, and registers. So when learning about the Java memory allocation principle, it is important to keep in mind that all this is done in the JVM, which is the basis and premise of the memory

large, which will occupy a lot of memory during array initialization, in this way, compilation may sometimes fail. yesterday there were several crashes and only 64 × 64 arrays were used. Later, we put array initialization out of main and use it as a global variable to statically allocate a piece of memory space in the stack. Although feasible, it also occupies a lot of
