Newbie, treating two inputs in a method and returning them?

Hey guys,

New to programming, messing around with it, wanted to write a download calculator program

my problem is dealing with returning the user input for download speed and filesize - can it be done in a single method? (two return statements not working)

if not, what's a simple and clever way to take two inputs, treat them and return them?

Code :

---

import java.text.DecimalFormat;
import java.util.Scanner;
 
/*
 * Program designed to allow a user to calculate how much time is left on his download
 * takes input of downloadspeed and filesize, then calculates on that input and prints it
 */
 
public class DownloadCalc {
 
	public static void main(String[] args) {
 
		Scanner myScanner = new Scanner(System.in);
		double downloadspeed = 0;
		double filesize = 0;
		double time = 0;
		DecimalFormat chronos = new DecimalFormat("00");
 
		//method for taking in data
		inputData(downloadspeed, filesize, myScanner);
 
		//method for printing the result of the data treatment
		printMe(theMath(downloadspeed, filesize, time), chronos);
 
 
	} //end main
 
	public static double theMath(double s, double f, double t){
		//time in seconds = filesize in GB * 1024 / downloadspeed
		t = (f * 1024)/s;
		return t;
	} //end theMath
 
	public static void printMe(double t, DecimalFormat c){
 
		double hours;
		double remainder;
		double seconds = t;
		double minutes;
 
		//conversion from only seconds into hours, minutes and seconds
		hours = seconds / 3600;
		remainder = seconds % 3600;
		minutes = remainder / 60;
		seconds = remainder % 60;
 
		System.out.println("Total time for download: " + c.format(hours) + ":" + c.format(minutes) + ":" + c.format(seconds));
 
	} //end printMe
 
 
		public static void inputData(double s, double f, Scanner mS){
 
		int choice;
		//switch for user to choose MB/GB, then input value	
		System.out.println("Download speed: press 1 for MB/s, 2 for GB/s ");
		choice = mS.nextInt();
		switch (choice){
		case 1: 
			System.out.println("You have chosen MB/s. Enter your download speed: ");
			s = mS.nextDouble();
			break;
		case 2:
			System.out.println("You have chosen GB/s. Enter your download speed: ");
			s = mS.nextDouble()*1024;
			break;
		} //end switch
 
		System.out.println("File size: press 1 for MB, 2 for GB ");
		choice = mS.nextInt();
		switch (choice){
		case 1: 
			System.out.println("You have chosen MB. Enter the file size: ");
			f = mS.nextDouble()/1024;
			break;
		case 2:
			System.out.println("You have chosen GB. Enter the file size: ");
			f = mS.nextDouble();
			break;
		} //end switch
 
		//MISSING RETURNS!
 
			} //end inputData
 
} //endclass

Well I don't know how other people would do it, but personally, I'd put those two values in a separate object, and then, return the object.

The answer is there:
Returning a Value from a Method (The Java™ Tutorials > Learning the Java Language > Classes and Objects)

public Bicycle seeWhosFastest(Bicycle myBike, Bicycle yourBike,
Environment env) {
Bicycle fastest;
// code to calculate which bike is
// faster, given each bike's gear
// and cadence and given the
// environment (terrain and wind)
return fastest;
}

Ok, thank you, I'll look into it
