Calculating Time Period Differences with Ease in Java

Introducing the Time Class

When working with time-related applications, calculating the difference between two time periods is a crucial task. In Java, you can achieve this by creating a custom class that handles time calculations efficiently.

The Time class has three essential member variables: hours, minutes, and seconds. As their names suggest, these variables store the hours, minutes, and seconds of a given time, respectively.

Initializing Time Values with a Constructor

To initialize the Time class, we’ll create a constructor that sets the values of hours, minutes, and seconds. This ensures that our Time objects are properly initialized with the correct time values.

public Time(int hours, int minutes, int seconds) {
    this.hours = hours;
    this.minutes = minutes;
    this.seconds = seconds;
}

Calculating Time Differences with a Static Method

Now, let’s create a static method called difference that takes two Time variables as parameters. This method will calculate the difference between the two time periods and return the result as a Time class object.

public static Time difference(Time time1, Time time2) {
    int hoursDiff = time1.hours - time2.hours;
    int minutesDiff = time1.minutes - time2.minutes;
    int secondsDiff = time1.seconds - time2.seconds;

    return new Time(hoursDiff, minutesDiff, secondsDiff);
}

Putting it All Together

Here’s the complete program that demonstrates how to calculate the difference between two time periods using the Time class:

public class Time {
    int hours;
    int minutes;
    int seconds;

    public Time(int hours, int minutes, int seconds) {
        this.hours = hours;
        this.minutes = minutes;
        this.seconds = seconds;
    }

    public static Time difference(Time time1, Time time2) {
        int hoursDiff = time1.hours - time2.hours;
        int minutesDiff = time1.minutes - time2.minutes;
        int secondsDiff = time1.seconds - time2.seconds;

        return new Time(hoursDiff, minutesDiff, secondsDiff);
    }

    public static void main(String[] args) {
        Time time1 = new Time(10, 30, 0);
        Time time2 = new Time(12, 45, 0);

        Time difference = difference(time1, time2);

        System.out.println("The difference between the two time periods is " + difference.hours + " hours, " + difference.minutes + " minutes, and " + difference.seconds + " seconds.");
    }
}
