Java Convert Number of Minutes to Hours

Tags: TimeUtil

In this Java tutorial, we learn how to convert a number of minutes into number of hours in Java programming language.

How to convert number of minutes to hours in Java

In the first step, we create a new Java utility class named TimeUtil, and implement a new method minutesToHours(int numberOfMinutes) which get number of minutes as an integer value and return number of hours as a double data type value.

TimeUtil.java 

public class TimeUtil {

    /**
     * Convert number of minutes to number of hours
     * @param numberOfMinutes number of minutes
     * @return number of hours
     */
    public static double minutesToHours(int numberOfMinutes) {
        double numberOfHours = Math.rint(numberOfMinutes / 60.0 * 100.0) / 100.0;
        return numberOfHours;
    }
}

In the following Java program, we show how to use the above TimeUtil class to convert a number of minutes to hours.

ConvertMinutesToHours.java 

public class ConvertMinutesToHours {
    public static void main(String... args) {
        int numberOfMinutes = 90;

        // Convert Number of Minutes to Hours
        double numberOfHours = TimeUtil.minutesToHours(numberOfMinutes);

        System.out.println("Number of minutes: " + numberOfMinutes);
        System.out.println("Number of hours: " + numberOfHours);
    }
}
The output as below. 
Number of minutes: 90
Number of hours: 1.5
