源代碼：
public class Math { public static void main(String[] args){ int a=1; int b=2; int c=(a+b)*10; } }
1 用Oolong工具將java字節碼翻譯為類匯編語言
.source Math.java .class public super Math .super java/lang/Object .method public <init> ()V .limit stack 1 .limit locals 1 .line 1 l0: aload_0 l1: invokespecial java/lang/Object/<init> ()V l4: return .end method .method public static main ([Ljava/lang/String;)V .limit stack 2 .limit locals 4 .line 4 l0: iconst_1 l1: istore_1 .line 5 l2: iconst_2 l3: istore_2 .line 6 l4: iload_1 l5: iload_2 l6: iadd l7: bipush 10 l9: imul l10: istore_3 .line 7 l11: return .end method
2 java –verbose查看運行類是加載了那些jar文件
3 javap查看字節碼
