testthrowexception.java

不错..................是java的源码

class MyException extends Exception {  //自定义的异常类
	String NewExceptionObject;
	public MyException() {  //构造函数
		this.NewExceptionObject="";
	}
	public MyException(String s) {  //构造函数
		this.NewExceptionObject=s;
	}
	String ShowExceptionInfo() {  //返回接收到的异常信息
		return this.NewExceptionObject;
	}
}
public class TestThrowException {
	public static void main(String[] args) {
		try	{
			throw new MyException("这是一个自行抛出的异常!");  //抛出异常
		}
		catch(MyException e) {
			System.out.println("MyException类：");
			System.out.println("已经捕捉到抛出的异常对象！");
			System.out.println("异常信息:"+e.ShowExceptionInfo());
		}
	}
}
