Problem 4
DO NOT USE ANY LOOPS,IF ELSE OR SWITCH CASE
Write a program that transforms numbers 1, 2, 3, 4, ....12 into the corresponding month names January, .........
For example, input is 5
Output is as follows:
Month name corresponding to 5 is May.

You will be writing a class MonthNames with a method for returning month name and any other thing required.
You also need to write a class TestMonthNames for taking input from user, creating object, calling methods and for output as shown above.


PLEASE CAN YOU GIVE CONCEPT OF HOW TO SOLVE ABOVE PROB

string GetMonth(int idx)
{
   string months[]={"January", "february","march","april","may","june","july","august","september","october","november","december"};
   return (months[idx]);
}

Put this in a class, format the output and submit the assignment.

You never said arrays were not allowed. Anyway, there must be some variation of calendar class u can use.

[siriusb]

import java.text.DateFormatSymbols
...
string GetMonth(int idx)
{
return (getMonths()[idx]);
}
...


It's more like a logic than actual code. See if that works.

[shivi4]

WE HAVE TO USE SIMPLE LOGIC
NO EXTERNAL CLASSES NO ARRAYS NO LOOPS IF/ELSE

NO SWITCH OR BREAK

ONLY CLASSES AND OBJECT S AND CONSTRUCTOR

DEFAULT DATA TYPE

This one shows a lot of output but the correct one is a complete word...

import java.io.*;
class Month
{
	public static void main(String args[]) throws IOException
	{
		String A;
		DataInputStream in = new DataInputStream(System.in);
		A=in.readLine();
		System.out.println(A.replaceAll("1","January"));
		System.out.println(A.replaceAll("2","February"));
		System.out.println(A.replaceAll("3","March"));
		System.out.println(A.replaceAll("4","April"));
		System.out.println(A.replaceAll("5","May"));
               // And So on....
	}
}

Save as Month.java

[shivi4]

we have to use only string class and its method

[QwertyManiac]

we have in built string class in java


we have to its method only like indexof,substring etc

[siriusb]

Well, he did use string clas and its methods. The datainputstream was only to get a kbd input. U can replace it with a function argument input.
