testmyexception.java

我在学习JAVA的讲义

public class TestMyException
{   static void Method(int a) throws MyException
    {   System.out.println("\t 调用方法 Method("+a+")");
        if (a>10||a<0)
            throw new MyException(a);
        System.out.println("\t 正常退出");
    }
    public static void main(String args[ ])
    {   try
        {   Method(1);
            Method(-3);
        }
        catch(MyException e)
        {   System.out.println("\t 捕获异常："+e.toString( ));
        }
    }
}

class MyException extends Exception
{   private int detail;
    MyException(int a)
    {   detail=a;}
    public String toString( )
    {   return "MyException"+detail;}
}
