Can I get some help? I have been trying to solve the Java course Binary Converter Code Project for 2 weeks now.

Question

https://code.sololearn.com/c5wBz5Up7Ve5/?ref=app

I want to return the binary of x, but it doesn't run at all. It says "invalid method declaration;return type required"

Answer 1

This error occurs because your toBinary method returns an integer but you didn’t put the declaration before the function name. It should be:
Public static int toBinary

However, you shouldn’t return your num variable, but binary variable.

So the method should be: public static String toBinary

return binary;

Answer 2

Wheew alright thanks a lot!

Answer 3

O ok thanks, however...Even though it runs now, it only always returns zero

Answer 4

I edited my answer, read it again please :p

Answer 5

The Code Project provided a code for that, but why's it always returning zero instead of the binary version

Answer 6

As I said you’re returning num variable, and you should return binary variable

Answer 7

Ok sorry I just saw that you had edited it. Alright I have done that but, String binary has already been defined in the method, that's the error message I am receiving now when I declare the String binary in the bracket as in toBinary(String binary)

Answer 8

I have solved it thanks

Answer 9

I should have maintained the int num in as in toBinary(int num).

So when I got that error message: String binary has already been defined

- I realized that, that I was doing the wrong thing by trying to pass the String binary as an argument. The goal is to pass the integer num instead
