一个关于Exception的基础题

要求大概就是:

 

 
1.一个包装了的异常类

package com;
 
public class MyException extends Exception {

 private static final long serialVersionUID = -1358391624708239344L;

 public MyException() {
  super();
 }

 public MyException(String message) {
  super(message);
 }

 public MyException(String message, Throwable cause) {
  super(message, cause);
 }

 public MyException(Throwable cause) {
  super(cause);
 }

 public String getMyMessage() {
  return "你的姓名" + getMessage();
 }

}

 

2.一个异常产生类

 
package com;

 
public class ExceptionMaker {

 public void throwException() throws MyException {
  try {
   throw new IllegalArgumentException();
  } catch (IllegalArgumentException e) {
   throw new MyException(e);
  }
 }
}

3.一个测试类

 

 
package com;

 
public class MyExceptionTest {
 
 public static void main(String[] args) {
  ExceptionMaker exceptionMaker = new ExceptionMaker();
  try {
   exceptionMaker.throwException();
  } catch (MyException e) {
   System.out.println(e.getMyMessage());
  }
 }
}
