Question

Define a class called Month. Your class will have one member variable of type int to represent a month (1 for January, 2 for February, and so forth). The complete class will include all the following member functions:

- a constructor to set the month using the first three letters in the name of the month.

- a constructor to set the month using an integer argument (1 for January, 2 for February, and so forth),

- a default constructor,

- an input function that reads the month as an integer,

- an input function that reads the month as the first three letters in the name of the month,

- an output function that outputs the month as an integer,

- an output function that outputs the first three letters in the name of the month,

- a member function that returns the next month as a value of type Month.

Embed the class definition in a test program.

Explanation / Answer

import java.util.*;
class Month
{
   int m;
   String sm;
   Month(String s)
   {
       sm=s;
   }

   Month(int mo)
   {
       m=mo;
   }

   Month()
   {
       m=0;
   }

   void setinp()
   {

       Scanner scan = new Scanner(System.in);

       System.out.println("Enter Month in 3 Letters");
       sm=scan.nextLine();
   }

   void setinp1()
   {

       Scanner scan = new Scanner(System.in);

       System.out.println("Enter Month in Integer");
       m=scan.nextInt();
   }

   int get()
   {
       return m;
   }

   String get1()
   {
       return sm;
   }
}

class TestMonth
{
   public static void main(String args[])
   {
       Month o=new Month(3);
       Month o1=new Month("Mar");

       o.setinp1();
       int aa=o.get();
      
       System.out.println("Integer Month is "+aa);

       o1.setinp();
       String ss=o1.get1();
       System.out.println("String Month is "+ss);
   }  
}
