I am trying to compare char to a String but getting an error. Error

error: incompatible types: unexpected return value

code:

public class MyClass {
    public static void main(String args[]) {
        String s = Integer.toBinaryString(2432);
        String p = "0";

        for (char c : s.toCharArray()) {
            return p.equals(new String(new char[]{c}));
        }
    }
}

The type of main() is void (public static void main(String args[]) {) and therefore you cannot return a value from it.

The actual error I get when I run this is:

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
Void methods cannot return a value
