Solve this program i need to write?

Question

Ok i am really struggling on making this program for my programming class. I major in Chemistry but i don't get why i need to learn how to program. Can someone help solve this program for me

You have been hired by the
Puerto Rico Olympic Committee to create a program that performs
measurement conversions. You need to work with the conversions for Team marathon runner.
The program should change from kilometers to miles and vice
-
versa.
Athletes should select
the type of action they want to change. If you do not choose an appropriate alternative, the program will
indicate that it has made ​​a mistake. If you choose an appropriate alternative, the program does the
calculation (measuring change) and display the results presented in
. BONUS: Add the structure
Repeat to repeat the program as many times as the user wants.

Try this, I hope it's what you wanted.  Good Luck!

import java.util.Scanner;

public class MarathonConverter {

public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		String input = "";
		do {
			System.out.println("To convert miles to kilometres, enter m");
			System.out.println("To convert kilometres to miles, enter k");
			System.out.println("To quit, enter q");
			input = scan.next();

switch(input) {
				case "m": miToKm(scan); break;
				case "k": kmToMi(scan); break;
				case "q": return;
				default: doError();
			} // end switch
		} while (true);
	} // end main()

public static void miToKm(Scanner in) {
		System.out.print("Enter miles: ");
		double miles = in.nextDouble();
		double km = miles * 1.6;
		System.out.println(miles+" miles = "+km+" kilometres.&#92;n");
	}

public static void kmToMi(Scanner in) {
		System.out.print("Enter kilometres: ");
		double km = in.nextDouble();
		double miles = km / 1.6;
		System.out.println(km+" kilometres = "+miles+" miles.&#92;n");
	}

public static void doError() {
		System.out.println("Error in input.  Please try again.&#92;n");
	}
} // end class

Maybe this isn't a test of programming skill, maybe it's a test of ethics?
