Java Program Execution Process

Now let us Understand the Java Architecture. 

As shown in above figure,

known as byte code.

JVM Parts

3) Then the java runtime environment (JRE) runs code compiled for a JVM.

4)The Class Loader performs the tasks of loading all .class files for the execution of a program.

5)The Byte Code verifier verifies the code that tests the format of code fragments and checks code fragments for illegal code.

6)The interpreter executes the code.
