In Java, memory is divided into several areas, each serving a specific purpose. The main memory areas in Java are: Write a comment Heap Memory: This is the runtime data area from which memory for all class instances and arrays is allocated. The heap is created when the Java Virtual Machine (JVM) starts and can grow or shrink as needed. Objects stored in the heap are accessible from anywhere in the application. Stack Memory: This area stores local variables and method call information. Each thread in a Java application has its own stack, which stores method calls and local variables. When a method is called, a new block is created on the stack, and when the method exits, that block is removed. Method Area: This is a part of the heap memory that stores class-level data, including class structures, method data, and constant pool. It is shared among all threads in the application. Program Counter (PC) Register: Each thread has its own PC register, which keeps track of the current instruction being executed. This helps the JVM to know where to continue execution after a method call or return. Native Method Stack: This area is used for native methods written in languages like C or C++. Each thread has its own native method stack, which stores the state of native method calls. These memory areas work together to manage memory allocation and deallocation, ensuring efficient execution of Java applications.
