Memory Allocation by JVM

#JVM ( #JAVA_VIRTUAL_MACHINE ) is an abstract machine,

It is a program which takes the #Java #bytecode and converts the byte code (line by line) into #machine_code

#JVM acts as a #run-time engine to run java applications

Operations performed by #JVM

1. Loading of code

2. Verification of code

3. Executing the code

4. It provides a #run-time environment to the users

Memory Areas Allocated by JVM

![[Pasted image 20230813094232.jpg]]

Class (Method) Area

-> This is the area in the memory block that stores the class code, variable code, method code, and the #constructor-method of the Java program

Heap

-> This is memory block where objects are created or objects are stored. -> Heap memory allocates memory for class interfaces and arrays. -> Allocates memory to objects at run time

Stack

-> Each #thread has a private JVM stack, created at the same time as the thread.
