HashMap stores key-value pairs. Alternate approach is to have a plain java class with key,value as attributes.
class HashMapAlternate{
Object key;
Object value;
}
You can create objects of HashMapAlternate and store it in arraylist. But HashMap is a better solution because it uses hashing and collision resolution technique which speeds up lookup when number of objects are very large.
