java判断数字是否为回文数

		Integer num = 112211;
		String str = num.toString();
		String arr[] = str.split("");
		boolean flag = true;
		for (int i = 0; i < arr.length/2; i++) {
			if(!arr[i].equals(arr[arr.length-1-i])){
				flag = false;
			}
		}
		if(flag){
		 System.out.println("该数字是回文数");
		}else{
		 System.out.println("该数字不是回文数");
