需求：從控制檯輸入時間，並輸出這個時間的下一秒

import java.util.Scanner;
public class {
	public static void main(String[] args){
		Scanner scanner = new Scanner(System.in);
		System.out.println("請輸入時： ");
		int hour = scanner.nextInt();
		System.out.println("請輸入分：");
		int minute = scanner.nextInt();
		System.out.println(
 
"請輸入秒：");
		int second = scanner.nextInt();

		if(hour >=0 && hour <= 23 && minute >=0 && minute <= 59 && second >=0 && second <= 59){
		
			if(++second >= 60){
				second = 0;
				if(++minute >=60){
				minute = 0;
					if(++hour >= 24){
				hour =
 
 0;
					}
				}
			}
		System.out.println(String.format("%02d : %02d : %02d",hour,minute,second));

		}else{
			System.out.println("輸入的時間有誤，請檢查後再輸入！");
		}

	}
