What is wrong in my code for the int to binary assignment?

Question

Whatever change I make, I still face some errors. Can you please tell me what is my mistake in this code?

import java.util.Scanner;

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

}
return num;
}
}
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

You put a ';' where it's supposed to be a '{' at the end of
public static String toBinary(int num)

Answer 2

Try return binary

Answer 3

Igor Kostrikin I tried it but it still gives "illegal start of type" error both for the line "while(num>0)" and line "return num" or as you recommend "return binary".

Answer 4

Thank you so much Odyel and Igor Kostrikin the corrections of both of you were required :D
