40 Code project

Question

Hello Dear Coders.
Can you give me some help.
I solved the problem in 40 Code project by myself, but i have feeling like i did it not good.
Can you please show me any other way for solving 40 Code project, my way was like that:

import java.util.Scanner;

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

}
}

class Converter{
int num;
String binary="";
public void setNum(int setNum){
this.num = setNum;
}
String toBinary(){
while (num>0){
binary = (num%2)+binary;
num /= 2;}
return binary;
}
}

thx )

Answer 1

//Expected code there is :

import java.util.Scanner;

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));
}
}

class Converter{

public static String toBinary(int num){
String binary="";

while (num>0){
binary = (num%2)+binary;
num /= 2;
}

return binary;
}
}
