Write code to create three instances of a HashMap class. Give two the same, and the third different data. Compare the objects and state the result

A map has the form Map <k,v> where: K: specifies the type of keys maintained in this map.V: defines the type of mapped values.Furthermore, the Map interface provides a set of methods that must be implemented. In this section, we will discuss about the most famous methods: clear: Removes all the elements from the map.containsKey: Returns true if the map contains the requested key.containsValue: Returns true if the map contains the requested value.equals: Compares an Object with the map for equality.get: Retrieve the value of the requested key.entrySet: Returns a Set view of the mappings contained in this map.keySet: Returns a Set  that contains all keys of the map.put: Adds the requested key-value pair in the map.remove: Removes the requested key and its value from the map, if the key exists.size: Returns the number of key-value pairs currently in the map.  Here is an example of TreeMap with a Map:   import java.util.Map; import java.util.TreeMap;   public class TreeMapExample {…

If a collection stores 10 objects, what value would be returned from a call to its size method?

what are the proper steps for this Create a client class named Client with the main( ) method. Inside the main method do the following: Create an instance of BiGBirdcalled Little Squadto store players’ information of U.S Swimm team team using the overload constructor to make the initial length of the list array equal to 2. Add eight players to Little Squad by hardcoding eight calls to the add method (one for each player). Display the contents of Little Squad Remove a random player from Little Squad Display the contents of Little Squad. Get but do not remove a reference to the 3rditem in the bag. Display the contents of the reference you “got” it step 5. Add another Player with another hardcoded add method call. Display the contents of Little Squad. Remove the Player that you “got” in step 5 using a call to the remove(E e)method. Display the contents of Little Squad.
