Java 抛异常的两种方法

import java.io.*;


public class EmployeeTest{
	EmployeeTest(){
		
	}
	
	public void Test1(int x) throws ArrayIndexOutOfBoundsException,ArithmeticException{
	    System.out.println(x);

	    if(x == 0){
	        System.out.println("没有异常");
	        return;
	    }

	    //数据越界异常
	    else if (x == 1){
	        int[] a = new int[3];
	         a[3] = 5;
	    }

	    //算术异常
	    else if (x == 2){
	        int i = 0;
	        int j = 5/0;
	    }
	}
	
	public void Test2(int x){
		try {
		    System.out.println(x);
	
		    if(x == 0){
		        System.out.println("没有异常");
		        return;
