Activity: Create a collection of objects using Java generics. use java to write code.

Create a Month class that can accept integer or String data type as an argument. The parameter type will be decided at run time. For this exercise, we will use Month class to store integer and string values that contains 12 months. For example, the integer value of 12 corresponds to string value of “December.” Use the following minimal class definition for Month class.

public class Month<T>

{

private T month;

public void setMonth(T month);

public T getMonth(); };

Create a new class, MonthApp. This new class will have main method, and will instantiate Month objects to store month indices and names. Here is an example using arrays.

// define
Month<Integer>[] monthsByNumber = new Month<>[12];
Month<String>[] monthsByName = new Month<>[12];
// adding values
monthsByNumber[0] = new Month<Integer>();
monthsByNumber[0].setMonth(1);
monthsByName[0] = new Month<String>();
monthsByName[0].setMonth("December");

Add Collections. Instead of arrays, use different collections to manage the month objects.
- ArrayList: Add two collection sets to main method of MonthApp class. One collection set will store monthIndex objects and other will store monthName objects.
- HashMap: Use a Month<Integer> as key, and Month<String> as value in a collection. This will make a key/value pair.

Populate the collection sets with appropriate month objects for month indexes and names. In total you will end up with 24 instances of Month class that will have integer values (1 thru 12) and string values (January thru December) for all 12 months.
