Question

I want to store distinct values of Strings with an integer associated with them. I have a Pair class that I have to use and a Collection that I have to return.
Is there any possible way to access the integer using a Collection.get(String key) method like a Map class can do?

Answer 1

I would suggest creating a new class that extends ArrayList<Pair<String,Integer>>

For example:

import java.util.ArrayList;
public class Test extends ArrayList<Pair<String, Integer>>{

    public Integer get(String value){
        for (Pair<String, Integer> item : this){
            if (item.getKey().equals(value)){
                return item.getValue();
            }
        }
        return null;
    }

}
