Why does it ask for a return statement? I think I have one... Help please!

Question

import java.util.Scanner;

//your code goes here
public class Converter{
static String toBinary(int num){
String binary="";
while(num > 0) {
binary = (num%2)+binary;
num /= 2;

return (binary);

}
}

}

public class Program {
public static void main(String[ ] args) {
Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
System.out.print(Converter.toBinary(x));

}

}

Answer 1

Paul Berger

It is giving error because it is not necessary to have num > 0 so return statement will not execute because it is written inside while loop.

So write return statement outside the loop.
