4. ABSTRACT
WHO WANTS TO BE A MILLIONAIRE? is a sensational game
show. For the thrill it offers to the viewers and the sum of amount it gifts
the participants. It promises a adrenaline rush for everyone and at the
same time it also improves our General Knowledge. The show is a life
changing platform for the doers. Here, we bring you the goodness of
such life changing experience in the form of app. This app offers the
user, rather player, a similar experience as such on the hot seat.
Although, the app is names El Greymatter as it tests your GK as well as
your thinking ability, in situations.
By running this app you go through a series of 15 questions, each
question offering you some amount. If the question is unanswerable you
can take help of the two help lines present.
Each help line works only once. To play the game you have to first give
your name at the opening page and then get on an answering streak.

5. HOMEPAGE:
This is the homepage of the APP. You have to enter your name in the jTextfield, it’ll be
saved in the database (MySQL) in two tables. One is “pro” which saves the player name and the
other “questions” which save the amount won by the player based on the no of questions he/she
answered.
By clicking on “CONTINUE”, you’ll be able to start the game. The code for
“CONTINUE” button is:
String name=tfname.getText();
JOptionPane.showMessageDialog(this,"WECOME "+name+".CLICK OK TO CONTINUE.");
JOptionPane.showMessageDialog(this,"ALL THE BEST.");
if (name.isEmpty())
JOptionPane.showMessageDialog(this,"PLEASE ENTER YOUR NAME.");

This is the sample page for a button. The amount you are answering
the question for will be highlighted with a white frame and the amount you’ve won
with a green frame above. If you click on the “correct option button” you’ll be

2000” is the correct answer choosing that will proceed to next answer form Q2).
Else, if you don’t know the answer for the question, you can flip it using the
