switch语句中如何终止外层while循环呢?

实现思路:
    1.在while循环上先定义标签
	2.switch中的终止标签 上编写
	   break while循环标签

loop: while(test.hasNextInt()){
    i = test.nextInt();
    switch(i){
        case 0:
		  //跳出while循环
          break loop; 
        case 1:
          System.out.println("case =1");
          break;
        case 2:
          System.out.println("case =2");
          break;
        default:
          System.out.println("无符合条件项目！");
    }
}
