String concatenation?

I am not 100% sure I know what String Concatenation is, or how to use it. Here's what I know:

String example = "marshmallo";
char exampleTwo = 'w';
example += exampleTwo;
    return example;

Is 'example' now 'marshmallow', or am I missing something?

Any help would be greatly apreciated. Thanks! -Uriah P.S. Is that how you spell concatenation?

Hi Uriah!

Your code won't work, because you're trying to concatenate two different data types. You have to use the StringBuilder.

StringBuilder sb = new StringBuilder();
example = sb.toString();
return example;

First I'm creating a new StringBuilder object. Then I'm using the append method to sort of concatenate the String and Char (which are two different data types). Lastly I'm assigning example a new value, which is the StringBuilder turned into a String. Of course I'm then returning example.

If you have any further question, feel free to ask!
