//Name:MyException1
//Description:MyException1

//Date:10-Feb-07

class MyException_1 extends Exception{
 MyException_1(String ErrorMessage){
  super(ErrorMessage);
 }
}

class MyException_2 extends Exception{
 MyException_2(String ErrorMessage){
  super(ErrorMessage);
 }
}


public class MyException{
 static int p(int a) throws MyException_1,MyException_2{
  switch(a){
   case 1:
    throw new MyException_1("a equals 1.");
   case 2:
    throw new MyException_2("a equals 2.");
   default:
    return(a*10);
  }
 }

 public static void main(String[] args){
  try{
   System.out.println(p(1));
  }catch(MyException_1 me1){
   System.out.println("MyException_1 processed.");
  }catch(MyException_2 me2){
   System.out.println("MyException_2 processes.");
  }try{
   System.out.println(p(2));
  }catch(MyException_1 me1){
   System.out.println("MyException_1 processed.");
  }catch(MyException_2 me2){
   System.out.println("MyException_2 processed.");
  }finally{
   System.out.println("Exception caught");
  }
 }
}

-------------------------------------------------
结果：
MyException_1 processed.
MyException_2 processed.
Exception caught
