Add the following method to the TimeSpan class:

public class TimeSpan {
    private int hours;
    private int minutes;
    
    public void add(int hours, int minutes) { ... }
    public int getHours() { ... }
    public int getMinutes() { ... }
    public String toString() { ... }

    // your code goes here
    
}
