Service Method trouble

Question

I'm having trouble calling upon a service Class method (Convert.java)i've created which:
1. Receives an Uppercase String
2. Converts the Uppercase String to a lowercase String.
3. Converts the now lowercase string into a single char.
4. Returns the char back to Main.java
Convert.java
    public class Convert {
    public static char con(String txt) {
    txt = txt.toLowerCase();
    char done = txt.charAt(0);
    return done;
}how would I send data to this service class method from a different module?

Answer 1

Are you asking how you'd invoke this method from a different class? You're using words with big connotations for what looks like a simple problem. It's not clear what you mean by "service method" other than just a static method, either.
If you want to invoke the method, just put the class name in front of it:
char c = Convert.con("Here is a string");Both the class and the method are public so you should have no trouble, unless you're using packages inconsistently.
