get from asm example

Disassembled view of the classes in Jasmin assembler format.

The trace printed when visiting the Hello class is the following:

 .bytecode 45.3
 .class public Hello
 .super java/lang/Object

 .method public <init>()V
 aload 0
 invokespecial java/lang/Object/<init>()V
 return
 .limit locals 1
 .limit stack 1
 .end method

 .method public static main([Ljava/lang/String;)V
 getstatic java/lang/System/out Ljava/io/PrintStream;
 ldc "hello"
 invokevirtual java/io/PrintStream/println(Ljava/lang/String;)V
 return
 .limit locals 2
 .limit stack 2
 .end method
 

where Hello is defined by:

 public class Hello {

     public static void main(String[] args) {
         System.out.println("hello");
     }
 }
