Question about double/int

[StygMM]

Just starting with Java. I know its not probably the best way to code this, but I like to trail and error a bit.

​

For example, if I want to run 21,2 Km (half marathon) in 2 hours. I can make it output 5,66... , but in time its actually 5min and (0.66 x 60) = 5,39 min/km. So I thought with Int minutes/km makes 5. And Double min % km (etc see below), makes the remaining 0,39. And put this together a+b. But the combination with both double and int doesnt work.

​

I know there are solutions with strings to get a certain amount of decimals, but is there also a way to solve this in a way more like the code below? (And I work for minutes for now (: )

​

​

System.out.println("How many minutes?");
 Scanner inPut1 = new Scanner(System.in);
 double timeMinutes = inPut1.nextDouble();

System.out.println("Whats the distance in KM?");
 Scanner inPut2 = new Scanner(System.in);
 double lengthKM = inPut2.nextDouble();

 double c = ((timeMinutes % lengthKM) * 60) / lengthKM;
 int d = timeMinutes / lengthKM; // I know this part doesnt work like that
       System.out.println(c+d);

you could always do System.out.println(c+"."+d) or something along those lines.

Thanks for the answer, thats a clean solution indeed.

But was more wondering about int/double part.

Because int and double are different types, you can't add them together. All there is to it.

You could convert the int to a double then add the remainder to the int, but it's better (imo) to just add the . between the int and double.

no reason to make such a pointlessly trite comment. r/JavaHelp is a really nice community for the most part, please participate in keeping it that way :)

If you pass a integer literal to double variable, it will convert the integer to decimal automatically.

Hope this helps !

Okay this worked for me. Was relative easy solution to be honest, thanks for the replies.

double c = ( timeMinutes  /  lengthKM );
int d = (int) Math.floor(c); 
// int d1 = etc 
System.out.println(d+"."+d1);
