Hello Everyone, I'm having a bit of trouble seperating my user interface code in a main class from my logic code in another class.

Basically i've put a while statement and some if statements in order to take input of a number from the user and decide which of two statements to call.

``````while ((result < 1) || (result > 2)) {
System.out.println("Enter 1 to convert from Pounds to Euros and 2 to convert from Euros to Pounds");
result = scan.nextInt();

}
if (result == 1) {

output123 = converter.PoundEuro(input, exchange);
System.out.println(output123);

} else if (result == 2) {

output123 = converter.EuroPound(input, exchange);
System.out.println(output123);

}``````

If i'm correct ideally parts of this should be in my other class and then it should be called. I'm a total Java novice so can't say for sure. But if i'm right does anyone have any suggestions on how to do this?

Put everything in a separate method. Have result, input and exchange as arguments and return the output123.

If separate, then separate:

``````import java.util.Scanner;

/**
*
* @author j3c
*/
public class Ranek {

static Scanner scan = new Scanner(System.in);

static int ConsoleOptionGUI(String s) {
int res = -1;
do {
System.out.println(s);
res = scan.nextInt();
} while (res < 0 || res > 2);
System.out.println("--> " + res);
return res;
}

public static void main(String[] args) {
int result = ConsoleOptionGUI("Enter 1 to convert from Pounds to Euros and 2 to convert from Euros to Pounds");
if (result == 1) {
// output123 = converter.PoundEuro(input, exchange);
// System.out.println(output123);
} else if (result == 2) {
// output123 = converter.EuroPound(input, exchange);
// System.out.println(output123);
}
}
}``````

Thanks for the advice. Its turns out that my code was already perfectly fine and I didn't need to move what I had. Just confusion on my part I feel.

Cheers all the same.
