exceptiondemo3.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 ExceptionDemo3{
	public static void main(String[] args){
		try{
			int len = args.length;
			System.out.println("\n Len = " + len);
			int b = 42/len;
			int[] c = {1};
			c[42]=99;
		}
		catch(ArithmeticException e1){
			System.out.println("发生了被0除异常！" + e1);
		}
		catch(IndexOutOfBoundsException e2){
			System.out.println("数组下标越界！" + e2);
		}
		catch(Exception e3){
			System.out.println("发生了异常！" + e3);
		}
		finally{
			System.out.println("finally语句被执行！");
		}
	}
}
