关于JAVA错误处理的有关问题

关于JAVA异常处理的问题
?创建一个异常类MyException。
?创建一个运程程序类，该类包含多个方法Method A、Method B、Method C。这些方法形成三级调用，主方法main调用Method A，Method A调用Method B，Method B调用Method C，最后Method C会抛出一个MyException的实例对象。
?Method A会捕获到Method C抛出的MyException对象两次。
?main方法也会捕获到Method C抛出的MyException对象两次。
?其运行结果如下所示：
  Method A called!
  Method B called!
  Method C called!
  Exception throw in MyException!
  Exception caught in Method A
  Exception finally statement in Method A
  Exception caught in Main
  Exception finally statement in Main
以下是我的代码：

Java code

public class MyException {    public static void main (String[] args) {          new MyException().MethodA();            }        public void MethodA(){        System.out.println("Method A called!");        try{            this.MethodB();        }catch(NewException e){            System.err.println(e);            System.out.println("Exception caught in Method A");        }finally{            System.out.println("Exception finally statement in Method A");        }    }        public void MethodB()throws NewException{        System.out.println("Method B called!");        this.MethodC();    }        public void MethodC()throws NewException{        System.out.println("Method C called!");        throw new NewException();            }    }class NewException extends Exception{        public String toString(){        return ("Exception throw in MyException!");    }}

无法做出题目需要的显示结果，因为Method A中已经捕获异常了Main中不是就捕获不到异常了吗？求指教，谁会教教我吧
 

[解决办法]
methodA catch到异常后再抛给main不就行了 你看看methodB不就是抛出去了
[解决办法]

Java code

public class MyException {    public static void main (String[] args) {          new MyException().MethodA();            }        public void MethodA()[color=#FF0000]throws NewException[/color]{        System.out.println("Method A called!");        try{            this.MethodB();        }catch(NewException e){            System.err.println(e);            System.out.println("Exception caught in Method A");            [color=#FF0000]throw e[/color]        }finally{            System.out.println("Exception finally statement in Method A");        }    }        public void MethodB()throws NewException{        System.out.println("Method B called!");        this.MethodC();    }        public void MethodC()throws NewException{        System.out.println("Method C called!");        throw new NewException();            }    }class NewException extends Exception{        public String toString(){        return ("Exception throw in MyException!");    }}

Java code

public class MyException {

   public static void main (String[] args) {
    
       new MyException().MethodA();
      
   }
  
   public void MethodA()[color=#FF0000]throws NewExc……

[解决办法]
a方法捕获后按照楼上的方法：
Java code
 public void MethodA()[color=#FF0000]throws NewException[/color]{        System.out.println("Method A called!");        try{            this.MethodB();        }catch(NewException e){            System.err.println(e);            System.out.println("Exception caught in Method A");            [color=#FF0000]throw e[/color]        }finally{            System.out.println("Exception finally statement in Method A");        }这样抛出，在main方法也捕获不到吧 ？？？？？？？？ 
 
[解决办法]

public class Test{
  
   public static void main(String[] args){
       Test test = new Test();
       try{
           test.MethodA();
       }catch(MyException e){
           System.out.println(" Exception caught in Main");
       }finally{
           System.out.println(" Exception finally statement in Main");
       }
   }
  
   private void MethodA() throws MyException{
       System.out.println("Method A called!");
       try{
           this.MethodB();
       }catch(MyException e){
           System.out.println(" Exception caught in Method A");
           throw new MyException();  
       }finally{
           System.out.println(" Exception finally statement in Method A");
       }
   }

   private void MethodB() throws MyException{
       System.out.println("Method B called!");
       this.MethodC();
   }

   private void MethodC() throws MyException{
       System.out.println("Method C called!");
       throw new MyException();
   }
}
