- Classloader. Classloader is a subsystem of JVM which is used to load class files. Whenever we run the java program, it is loaded first by the classloader.
- Class(Method) Area. Class(Method) Area stores per-class structures such as the runtime constant pool, field and method data, the code for methods.
- Heap. It is the runtime data area in which objects are allocated.
- Stack. Java Stack stores frames. It holds local variables and partial results, and plays a part in method invocation and return. Each thread has a private JVM stack, created at the same time as thread.
Oct 28, 2022 · The JVM has two primary functions: to allow Java programs to run on any device or operating system (known as the “write once, run anywhere” principle), and to manage and optimize program memory.
- Class Loader. When you compile a .java source file, it is converted into byte code as a .class file. When you try to use this class in your program, the class loader loads it into the main memory.
- Runtime Data Area. There are five components inside the runtime data area: Let's look at each one individually. Method Area. All the class level data such as the run-time constant pool, field, and method data, and the code for methods and constructors, are stored here.
- Execution Engine. Once the bytecode has been loaded into the main memory, and details are available in the runtime data area, the next step is to run the program.
- Java Native Interface (JNI) At times, it is necessary to use native (non-Java) code (for example, C/C++). This can be in cases where we need to interact with hardware, or to overcome the memory management and performance constraints in Java.
