exceptiondemo2.java

这个是JAVA程序基础书上第五章接口实现的代码

import java.io.*;
public class ExceptionDemo2{
	public static void main(String[] args){
		try{
			int len = args.length;
			System.out.println("\n Len = " + len);
			try{
				int b = 42/len;
			}
			catch(ArithmeticException e1){
				throw new MyException2();
			}
			int[] c = {1};
			c[42]=99;
		}
		catch(IndexOutOfBoundsException e2){
			System.out.println("发生了数组越界异常！" + e2);
		}
		catch(MyException2 e3){
			System.out.println("捕获了内层catch语句中所抛出的MyException2类的异常！");
		}
	}
}
