public class Converter{
public static void toBinary(int x) {

String binary = "";
while (x > 2 ){
binary = (x%2) + binary;
x /= 2;
}
}

}
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

Your toBinary() method is void type but you expecting to print returned value in
System.out.println( Convertor.toBinary(x)) ; // since called method is void, does not return anything...
Either return value or just call method without print statement...
