import java.util.Scanner;public class Test2_8 {public static void main(String[] args) {Scanner input = new Scanner(System.in);System.out.println("Enter the time zone offset to GMT:");int offset = input.nextInt();// Obtain the total milliseconds since midnight, Jan 1, 1970long totalMilliseconds = System.currentTimeMillis();// Obtain the total seconds since midnight, Jan 1, 1970long totalSeconds = totalMilliseconds / 1000;totalSeconds += offset * 60 * 60;// Compute the current second in the minute in the hourlong currentSecond = totalSeconds % 60;// Obtain the total minuteslong totalMinutes = totalSeconds / 60;// Compute the current minute in the hourlong currentMinute = totalMinutes % 60;// Obtain the total hourslong totalHours = totalMinutes / 60;// Compute the current hourlong currentHour = totalHours % 24;// Display resultsSystem.out.println("Current time is " + currentHour + ":"+ currentMinute + ":" + currentSecond + " GMT");}
}

破题

在理解2.8题目的基础上只需要更改一小部分即可
我的理解，是在最后输出前增加对小时的变换
对12求余即可获取3.30要求的小时数
原数除12如果为0后面跟AM，如果为1后面跟PM

代码

import java.util.Scanner;public class Test2_8 {public static void main(String[] args) {Scanner input = new Scanner(System.in);System.out.println("Enter the time zone offset to GMT:");int offset = input.nextInt();// Obtain the total milliseconds since midnight, Jan 1, 1970long totalMilliseconds = System.currentTimeMillis();// Obtain the total seconds since midnight, Jan 1, 1970long totalSeconds = totalMilliseconds / 1000;totalSeconds += offset * 60 * 60;// Compute the current second in the minute in the hourlong currentSecond = totalSeconds % 60;// Obtain the total minuteslong totalMinutes = totalSeconds / 60;// Compute the current minute in the hourlong currentMinute = totalMinutes % 60;// Obtain the total hourslong totalHours = totalMinutes / 60;// Compute the current hourlong currentHour = totalHours % 24;long currentHour_12 = currentHour % 12;// Display resultsif(currentHour / 12 == 0)System.out.println("Current time is " + currentHour_12 + ":"+ currentMinute + ":" + currentSecond + " AM");elseSystem.out.println("Current time is " + currentHour_12 + ":"+ currentMinute + ":" + currentSecond + " PM");}
}
