1. Create a “toString()” method for the following code.

// Represents a time span of hours and minutes elapsed.

// Class invariant: minutes < 60

public class TimeSpan {

    private int hours;

    private int minutes;

    // Constructs a time span with the giveninterval.

    // pre: hours >= 0 && minutes>= 0

    public TimeSpan(int hours, int minutes) {

        this.hours = 0;

        this.minutes = 0;

        add(hours,minutes);

    }

   

    // Adds the given interval to this timespan.

    // pre: hours >= 0 && minutes>= 0

    public void add(int hours, int minutes) {

        this.hours +=hours;

        this.minutes +=minutes;

       

        // convert each 60minutes into one hour

        this.hours +=this.minutes / 60;

        this.minutes =this.minutes % 60;

    }

}
