Please I need help

Question

The binary numeric system uses only two digits: 0 and 1. Computers operate in binary, meaning they store data and perform calculations using only zeros and ones.

You need to make a program to convert integer numbers to their binary representation.
Create a Converter class with a static toBinary() method, which returns the binary version of its argument.
The code in main takes a number as input and calls the corresponding static method. Make sure the code works as expected.

Sample Input:
42
Sample Output:
101010

What I did
import java.util.Scanner;
public class Converter{
public static int toBinary(int x);
String binary="";
while (x>0){
binary=(x%2)+binary;
x=x/2;
}
return x;
}
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

Thank you Coding Santa

Answer 2

Your method returns "x"
better is return "binary"
But therefore you have to change the return type of your method from int to String.

Answer 3

And one pair of curly braces are missing:
After the method declaration (instead that semi colon) and after the return statement.

public class Converter {
public static String toBinary(int x) {
String binary="";
while (x>0) {
binary=(x%2)+binary;
x=x/2;
}
return binary;
}
}
