Add up time with a class

[psyghotic]

Hey,

I have to make a class to add up time.

the methods and the variables i have to use are.

Time class

private int hour
private int minute
private int second

the methods of this class are

time(int h,int m, int s)
void show()
time addUp(time t)
void expand(time t)
void setHour(int h)


This class has to be called on from TestTime class where you make two objects of the time type, add these up and show them on screen


This is something i have to do for school but can't get out off

Thnx

You'll have to be more specific than that. What have you done so far, and which bits are you finding hard? No one will do it for you, but we will help you.

class Time {

private int hour;
private int minute;
private int second;

Time(int u,int m,int s){
hour = u;
minute = m;
second = s;
}

public int addup(tijd t){


return ??;
}
public static void Show(){

System.out.println("The result is " + ??????);
}


}


In the time class i don't now how to add up time. and use setTime method

code to add up time :

result=((second+second)%60) +(((second+second)/60)+((hour+hour)%60))+
(((hour+hour)+((minute+minute)/60)

meaning you add up the seconds and whats over 60 seconds (1 minute) is seconds , same for minutes. I know this isn't the right code but it's the idea of it that i know, but how do i put this in a method (addup).

Class TestTimeç

public static main(String []args){

Time t1 = new Time(10.20,12);
time t2 = new Time( 20.30,14);

}


here i have to call on the methods in Time to add them up and show the result.

can i call on the show method with Time.show()

Well first up, your addUp method needs to return a Time object, not an int. You need to change its signature.

For the method, declare three int variables and name them newHour, newMinute and newSecond. Then use the formula you have to calculate the new values for these. eg

 newSeconds = (this.seconds + t.getSeconds) % 60;

You then need to use these variables to create a new Time object, and return it.
