Implements Comparable to get alphabetical sort with Strings

Question

I would like an object to be comparable (to use it in a TreeSet in that case).

My object got a name field and I would like it to be sorted by alphabetical order.

Answer 1

You are overthinking the problem. Strings have their own natural ordering, which is alphabetic, so you can just use the String.compareTo like this:

@Override
public int compareTo(MyObject otherObject) {
    return this.name.compareTo(otherObject.name);
}
