计算时间 - 爱码网

按小时，分钟，秒读取时间，然后打印等价的秒数。（例如，1小时28分42秒等于5322秒）

Code
package csdn.kao331431214.number2;

import java.util.Scanner;

public class Time1 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        int xiaoshi, fenzhong, miao;

        Scanner scan = new Scanner(System.in);
        System.out.println("小时：");
        xiaoshi = scan.nextInt();
        System.out.println("分钟：");
        fenzhong = scan.nextInt();
        //判断输入的分钟是否错误
        while(fenzhong >= 60){
            System.out.println("你输入时间：" + fenzhong +"分钟错误，请从新输入：");
            System.out.println("分钟：");
            fenzhong = scan.nextInt();
        }
        System.out.println("秒：");
        miao = scan.nextInt();
        //判断输入的秒是否错误
        while(miao >= 60){
            System.out.println("你输入时间：" + miao +"秒错误，请从新输入：");
            System.out.println("秒：");
            miao = scan.nextInt();
        }

        System.out.println("你输入的时间是："
                + xiaoshi +"小时" + fenzhong +"分钟" + miao +"秒");

        miao = xiaoshi * 3600 + fenzhong * 60 +miao;
        System.out.println("换算后的时间是：" + miao +"秒");

    }

}

对上面的题目反向计算

Code
package csdn.kao331431214.number2;

import java.util.Scanner;

public class Time2 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        int xiaoshi, fenzhong, miao;

        Scanner scan = new Scanner(System.in);
        System.out.println("请输入要计算的时间（秒）：");
        miao = scan.nextInt();
        System.out.println("你输入的时间是：" + miao +"秒");

        xiaoshi = miao / 3600;
        fenzhong = miao / 60 - (xiaoshi * 60);
        miao = miao % 60;

        System.out.println("换算后时间是："
                + xiaoshi +"小时" + fenzhong +"分钟" + miao +"秒");
    }

}
