The JVM memory area is mainly divided into the following sections:<\/p>\n

    \n
  1. Program Counter Register stores the address of the bytecode instruction currently being executed by the thread.<\/li>\n
  2. The Java Virtual Machine Stack is responsible for storing information such as local variables, the operand stack, dynamic linking, and method return for each thread when running a Java method.<\/li>\n
  3. Native Method Stack: Similar to the Java Virtual Machine stack, it is used to execute native methods.<\/li>\n
  4. Java Heap: used for storing object instances and arrays. It is a memory area shared by all threads.<\/li>\n
  5. Method Area: utilized for storing class information, constants, static variables, and code compiled by the just-in-time compiler.<\/li>\n
  6. The Runtime Constant Pool, part of the method area, is used to store various literals and symbol references generated during compilation.<\/li>\n
  7. Direct Memory: Not part of the JVM memory area, but interacts with off-heap memory, mainly used for NIO operations.<\/li>\n<\/ol>\n

    The division principle of JVM memory regions is designed to meet the storage needs of different types of data, as well as to carry out memory management and garbage collection. This division allows for more efficient memory management and helps to prevent issues such as memory leaks.<\/p>\n","protected":false},"excerpt":{"rendered":"
