Hi Sharma,
You can try with the 'javap' or' javap -c' utility to read the byte code.
Sun says: The Java SDK from Sun includes the javap disassembler, that will convert the byte codes into human-readable mnemonics.
I have given a try for sample Test.java class which you provided.
H:\msripad>javac Test.java
H:\msripad>javap Test
Compiled from "Test.java"
public class Test extends java.lang.Object{
public Test();
}
H:\msripad>javac Test.java
H:\msripad>javap Test
Compiled from "Test.java"
class Test extends java.lang.Object{
Test();
}
H:\msripad>javap -c Test
Compiled from "Test.java"
class Test extends java.lang.Object{
Test();
Code:
0: aload_0
1: invokespecial #1; //Method java/lang/Object."<init>"

)V
4: return
}
