打开eclipse编译后的.class文件

众所周知，用文本编辑器打开.class文件会乱码。我们可以使用命令行打开.class文件
项目结构：

代码：

public class Synchronized {
     public static void main(String[] args) {
            // 对Synchronized Class对象进行加锁
            synchronized (Synchronized.class) {

            }
            // 静态同步方法，对Synchronized Class对象进行加锁
            m();
        }

        public static synchronized void m() {
        }
}

cmd到~\ThreadTest\bin\testnew，即cmd到.class文件的同级目录下（.class文件在项目路径下的bin文件夹下），执行：javap -v Synchronized.class

可以看到Synchronized.class文件内容如下：

  public static void main(java.lang.String[]);
    descriptor: ([Ljava/lang/String;)V
    flags: ACC_PUBLIC, ACC_STATIC
    Code:
      stack=2, locals=1, args_size=1
         0: ldc           #1                  // class testnew/Synchronized
         2: dup
         3: monitorenter
         4: monitorexit
         5: invokestatic  #16                 // Method m:()V
         8: return
      LineNumberTable:
        line 6: 0
        line 10: 5
        line 11: 8
      LocalVariableTable:
        Start  Length  Slot  Name   Signature
            0       9     0  args   [Ljava/lang/String;

  public static synchronized void m();
    descriptor: ()V
    flags: ACC_PUBLIC, ACC_STATIC, ACC_SYNCHRONIZED
    Code:
      stack=0, locals=0, args_size=0
         0: return
      LineNumberTable:
        line 14: 0
      LocalVariableTable:
