What structure to store three related values ​​to use in Java?

Question

Java

Good afternoon, habralyudi!
Now in our project we use the usual HashMap to store key-value data (in fact, value-value, since the key itself is also used and there is always a complete enumeration of all elements).
At the moment, it was required to store a third value. What is the best structure to use for a triple of related values ​​(value-value-value)?
So far, I've thought of creating a class that stores all 3 values, and creating an ArrayList from objects of this class.

Answer 1

And if you push a pair as a value in HashMap? And wrap it all up in an adapter for convenience.
Still, if you need a HashMap (quick access), then ArrayList is a problem.
