***********************************************************************************************

import java.io.*;

public class string 

{

    public static void main(String args[])

    {

        String pass,user;

        try

        {

            DataInputStream x=new DataInputStream(System.in);

            System.out.println("Enter user name :");

            user=x.readLine();

            System.out.println("Enter password :");

            pass=x.readLine();

            if(user.equalsIgnoreCase("Priyada")&&pass.equals("java"))

                    {

                        System.out.println("LOGIN");

                    }

                    else

                       {

                              System.out.println("Invalid user name or password"); 

                       }     

        }

     catch(Exception e)

     {

     }

  }

}

=========================================================================

Output : 

Here, I am giving the user name as "Priyada" and password as "java"    .

In this program , only password is case sensitive.

In the output , if we give the correct user name and password, a message will appear as "LOGIN".

Otherwise , "Invalid user name or password"will be displayed.

run:

Enter user name :

priyada

Enter password :

java

LOGIN

==================================================================

Note : 

We can give LOGIN table as shown below : 

The program to draw table like this , will follow soon.....
