访问匿名类方法时出现问题

Question

我已经编写了这段代码，这会在run（）方法的行上生成错误的表达式开头，请解决我的问题。

     class Reentrant 
        {
            public synchronized void m() 
            {
                 n();  
                    System.out.println("this is m() method");  
                }  


            public synchronized void n() 
            {  
                    System.out.println("this is n() method");  
                }
            {  
                public void run(){  
                        m();//calling method of Reentrant class  
                }  
            };  
        }  
        class ReentrantExample
        {  
            public static void main(String args[])
            {  
                Reentrant re=new Reentrant();  

                Thread t1=new Thread();

                t1.start();  
            }
        }

更改代码，

{  
            public void run(){  
                    m();//calling method of Reentrant class  
            }  
        };

到

  public void run(){  
                    m();//calling method of Reentrant class  
            }
