Question

I would like to create a sorted set with some sample data using CompareTo.

Can you provide some sample coding on how to do this?

Answer 1

You need a compareTo method in your class that you want to compare with others, and have the class implement comparable:

public class TestObject implements Comparable{
    private int a_number;

public int getNumber() {
   return a_number;
   }

public int compareTo(TestObject other) {
   return getNumber() - other.getNumber();
   }
}

You can now compare objects of this class with objects of the same class
