ABSTRACT
You’re only young once but you can be immature forever.
The basic idea behind MENTAL AGE CALCULATOR is the gap between
our BIOLOGICAL & EMOTIONAL Age .
OR in simple words ,our Physical & Mental age. This quiz based game is
based upon different choices a person would make during each phase of life.
Like a child has some liking for a particular type of food in his childhood but
might not like it in some other phase .Our emotions describe who we are, why
we do the things we do & what would be our liking. Emotional or mental age
is a factor very important to describe someone’s character .A Person acting
all high & mighty could be a child at mental level. These differences inspired
the basic idea behind this project.

1.INTRODUCTION
• PURPOSE
This quiz sort of game is just for referring to one’s mental age .Don’t
be offended if you got a mental age of an old one while physically still
being in your 20’s,it simply means that you’ve got a mature mind .Also
if you receive mental age of a child while actually being a old man .But
hey ,Old age is the second childhood ,right.

2.Technologies Used
➢ Introduction to Java
• Java is Object oriented, Multi-threading language developed by Sun Microsystems in 1991.
• It is designed to be small, simple and portable across different platforms as well as OS.
Features of Java:
Syntax based on C++
✓ Object-oriented , Secure & portable
✓ Multithreaded & High Performance
✓ Support for Internet applications
✓ Extensive library of prewritten classes
✓ Portability among platforms
✓ Built-in networking security as JRE is inaccessible to other parts of computer
➢ Java Swing
Swing is a set of program component s for Java programmers that provide
the ability to create graphical user interface ( GUI ) components, such as buttons and
scroll bars, that are independent of the windowing system for specific operating system
. Swing components are used with the Java Foundation Classes ( JFC )
Swing provides a choice of looks and feels. For example, the same program can use
either the Java look and feel or the Windows look and feel. We expect many more look-
and-feel packages -- including some that use sound instead of a visual "look" -- to
become available from various sources.

3.Requirements
Hardware:
1.) Processor PENTIUM 4 or Above
2.) Minimum 64 MB DDR SDRAM
3.) 4GB or more Hard disk space.
Software:
1.) Java JDK Platform
2.)Windows & or above
3.) Technology : Swing
4.)Environment : Command Prompt , Eclipse

5.SNAPSHOTS
Main Menu:-

Record Submission :-
Result :-

HELP Menu :-
Previous Player’s result :-

Creator’s info:-
The idea :-

6.Further Development
Despite being quite accurate this idea still needs to
meet with innovation.It has the continuovs need of
updated information for changing generation to
judge people’s choices.Further scope of it’s
development would be to merge it with an Artificial
Intellligent system which can interact with
people,provide response,humour them, read their
choices & do more stuff.
By collecting data on a single person per database
It can be true to the mark when there is a need to
judge it’s owner’s character.
Hence the project to calculate one’s mental age is
complete.
