Problem with my code

Question

Hey guys! I tried to do the Binary Converter in Java Chapter 4 but it doesnt work! Some1 knows what I did wrong? This is my code :
import java.util.Scanner;

public class Converter (){
public 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));
}
}

Hope someone could help!

Answer 6

You can try this maybe it helps.

import java.util.Scanner;

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

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 7

In the task it says that you can program it with this :
String binary="";
while(num > 0) {
binary = (num%2)+binary;
num /= 2;
}

I guess this is wrong or? Or can you do it with that?
