I hope this helps you

import java.util.HashMap;

public class MyHashMap {
    private static HashMap<String, String[]> subjects;

    public static void main(String[] args) {
        subjects = new HashMap<String, String[]>();
        subjects.put("calculus", new String[] { "math", "logic" });
        subjects.put("chemisty", new String[] { "ions", "electrons" });
        subjects.put("biology", new String[] { "life", "bacteria" });
        for (String s : subjects.get("biology")) {
            System.out.println(s);
        }

    }
}
