源代码：

public class Math {        public static void main(String[] args){        int a=1;        int b=2;        int c=(a+b)*10;    }}

1 用Oolong工具将java字节码翻译为类汇编语言

.source Math.java.class public super Math.super java/lang/Object.method public 
     
       ()V.limit stack 1.limit locals 1.line 1l0:    aload_0l1:    invokespecial java/lang/Object/
      
        ()Vl4:    return.end method.method public static main ([Ljava/lang/String;)V.limit stack 2.limit locals 4.line 4l0:    iconst_1l1:    istore_1.line 5l2:    iconst_2l3:    istore_2.line 6l4:    iload_1l5:    iload_2l6:    iaddl7:    bipush 10l9:    imull10:    istore_3.line 7l11:    return.end method
      
     

2 java –verbose查看运行类是加载了那些jar文件

3  javap查看字节码
