In the existing class UnsortedTableMap, the method put(k,v) is used to add an entry to a map. This method spends time to locate an existing item with the given key. Provide a non-static method named putOnlyIfAbsent(k,v) that adds the entry to the map only if there is no entry with a key k. In case an entry with key k already exists, then just return the existing value corresponding to the key. The new method should be provided in the class UnsortedTableMap. Write the testing code in the main method of the class UnsortedTableMap.

Map

A map is defined as the name of a higher-order function in most of the programming languages that applies a given function to each element of a functor, such as a list, and returns a list of results in the same order. A map is also called the collection of values based on a key, i.e. a key and value pair. A map has its own set of keys. Duplicate keys are not permitted in the Map, although duplicate values are permitted. Because a Map cannot be navigated, it must be converted to a Set using the keySet() or entrySet() methods. For key-value association mapping, such as dictionaries, maps are ideal.
