Im writing the demo for my class to demonstrate each method. The class takes a number and assigns it to a month, or is supposed to. I have it working to say month 1 is January, month 2 is February and so on. I want to user to enter a month and set that to a number, how can I do this? Here is my class and driver:
Class:
/**
Month Class

*/
public class Month
{
private int monthNumber;
/**
The No-arg constructor initializes the object to
month #1.
*/

{

}
/**

@param m The month number to initialize the object to.
*/
public Month(int m)
{
if (m < 1 || m > 12)
monthNumber = 1;
else
monthNumber = m;
}
/**
Constructor
@param name The name of the month to initialize the object to.
*/
public Month(String name)
{
if (name.equalsIgnoreCase("january"))
monthNumber = 1;
else if (name.equalsIgnoreCase("february"))
monthNumber = 2;
else if (name.equalsIgnoreCase("march"))
monthNumber = 3;
else if (name.equalsIgnoreCase("april"))
monthNumber = 4;
else if (name.equalsIgnoreCase("may"))
monthNumber = 5;
else if (name.equalsIgnoreCase("june"))
monthNumber = 6;
else if (name.equalsIgnoreCase("july"))
monthNumber = 7;
else if (name.equalsIgnoreCase("august"))
monthNumber = 8;
else if (name.equalsIgnoreCase("september"))

else if (name.equalsIgnoreCase("october"))
monthNumber = 10;
else if (name.equalsIgnoreCase("november"))
monthNumber = 11;
else if (name.equalsIgnoreCase("december"))
monthNumber = 12;
else
monthNumber = 1;
}
/**

@param m The number of the month.
*/
public void setMonthNumber(int m)
{
if (m < 1 || m > 12)
monthNumber = 1;
else
monthNumber = m;
}
/**
The getMonthNumber method gets the month number.
@return The number of the month.
*/
public int getMonthNumber()
{
return monthNumber;
}
/**
The getMonthName method gets the name of the month.
@return The name of the month.
*/
public String getMonthName()
{

switch (monthNumber)

}
return name;
}
/**

@return A reference to a String representation of
the object.
*/

the same month, false otherwise.
*/

status = true;
else
status = false;
return status;
}
/**

than the argument, false otherwise.
*/

}
}Driver so far:
import java.util.Scanner;
public class MonthDemo
{
public static void main(String[] args)
{
// Use the no-arg constructor.
Month object1 = new Month();
System.out.println("Month " + object1.getMonthNumber() +
" = " + object1);
Month object2 = new Month(2);
for (int i = 1; i <= 12; i++)
{
object2.setMonthNumber(i);
System.out.println("Month " + object2.getMonthNumber() +
" name is " + object2);
}
String mName;
Scanner keyboard = new Scanner(System.in);
Month object5 = new Month("January");
System.out.println("Enter a month name: ");
mName = keyboard.nextLine();
System.out.println(object5.mName());
}
}
