TUMBLERZ

Tumblerz is an educational game which is helpful for the player to increase his I.Q. level,

concentration, patience, memory power and logical thinking abilities. This game is based on the

water-jug problem which is a part of artificial intelligence studies.

Tumblerz is the collection of three categories of games.

Namely :

1. JUNGLE2. RAIN3. DESERTThe names of the games corresponds with the features available in the games.

JUNGLE :

In jungle game, we have unlimited water supply as is present in jungles.Here, in this game we

are given some unmarked tumblerz which are empty but we know their capacity, unlimited water

and target for each given tumbler. Here with target we mean the amount of water which is to be

filled in that tumbler. Our objective is to reach the target state.We have 40 levels for this game. Player will not be able to access next level before going through previous level.

NETBEANS IDE

NetBeans IDE is an open-source integrated development environment. NetBeans IDE supports

development of all Java application types (Java SE (including JavaFX), Java ME, web, EJB and

mobile applications) out of the box.

Modularity: All the functions of the IDE are provided by modules. Each module provides a well

defined function, such as support for the Java language, editing, or support for the CVS

versioning system, and SVN. NetBeans contains all the modules needed for Java development in

a single download, allowing the user to start working immediately. Modules also allow NetBeans

7/29/2019 Tumbler 1

to be extended. New features, such as support for other programming languages, can be added by

installing additional modules. For instance, Sun Studio, Sun Java Studio Enterprise, and Sun

Java Studio Creator from Sun Microsystems are all based on the NetBeans IDE.

License: From July 2006 through 2007, NetBeans IDE was licensed under Sun's Common

Development and Distribution License (CDDL), a license based on the Mozilla Public License

(MPL). In October 2007, Sun announced that NetBeans would henceforth be offered under a

dual license of the CDDL and the GPL version 2 licenses, with the GPL linking exception for

GNU Classpath.

Java SE Application

A Java SE application is an application written to the Java Platform, Standard Edition (Java SE).

The same unmodified Java SE applications can be run on almost any computer, whether that

computer uses the Microsoft Windows, Solaris, Linux, or MacOS X operating systems. The key

to this application portability is the Java Runtime Environment, which is available free of charge

for most operating systems, including all of the ones mentioned above.

In addition to being a platform for multi-platform desktop applications, the Java SE platform is

the basis for other technologies such as Java Platform, Enterprise Edition. You might find

yourself writing Java code that provides back-end logic for web and enterprise applications as

well.

FEATURES:

Desktop Application Development

Java SE is the programming platform for developers who create browser applets, command line

tools, and graphical user interfaces targeted for desktop users. Applications written in Java run

on Windows, Mac OS, Linux, Solaris and other operating systems.

Annotation Processors

7/29/2019 Tumbler 1

7/34

Attach annotation processors to a project and use them while working on your code. The

NetBeans IDE supports third-party annotation processors, such as JPA 2.0 from JEE or custom

ones.

Javadoc Integration

Use the Auto Comment action to generate Javadoc code for your methods. Use the Javadoc

Analyzer plugin to check and fix existing Javadoc comments.

Java Call Hierarchy

The Java Call Hierarchy view displays a tree representing the hierarchy of callers and callees of

the selected method in a project.

Compile on Save

The Build action has been replaced by the Compile on Save feature: Now the IDE builds your

project automatically and the run/debug/test actions are immediately available after saving a file.

If you save changes to a method while the debugger is already running the running application

will be automatically reloaded. Compilation errors inside a method don't stop you from running

your program: The debugger will halt when the program runs into the method in question.

Unit Testing Tools

7/29/2019 Tumbler 1

8/34

JUnit 3 and 4 are integrated into the IDE. You can quickly create, run and re-run unit tests and

view the test results in the IDE. The editor provides keyboard shortcuts for fast navigation

between the test and the class it is testing.

Non-Proprietary Project Build System

The NetBeans IDE stores your project information in open, extendible, non-proprietary formats

such as Apache Ant and Maven scripts.

Integrated Tools

The Java Bean support makes Bean property generation and BeanInfo editing easier. The

NetBeans GUI Builder assists you with Java Swing development, from the prototype to the final

graphical user interface. The well-integrated NetBeans debugger and the NetBeans profiler help

you to write rock-solid Java desktop software.

SYSTEM STUDY AND ANALYSIS

System analysis is a process of gathering and interpreting facts, diagnosing problems and the

information to recommend improvements on the system. System analysis or study is an

important phase of any system development process. The system is studied to the minutest detail

and analyzed. The system is viewed as a whole and the input to the system are identified. System

analysis is concerned with becoming aware of the problem, identifying the relevant and

decisional variables, analyzing and synthesizing the various factors and determining an optimal

or at least a satisfactory solution or program of action.

FEASIBILITY STUDY

Feasibility study is both necessary and prudent to evaluate the feasibility of the project at the

earliest possible time. It involves preliminary investigation of the project.

The different types of feasibility are:

1. Technical feasibility2. Operational feasibility3. Economical feasibility

Technical feasibility

Technical Feasibility deals with the hardware as well as software requirements. We have to find

out whether the necessary technology, the proposed equipments have the capacity to hold the

data, which is used in the project, should be checked to carryout this technical feasibility.

Technical feasibility in this project:

The main applet can be made using NetBeans IDE or Eclipse IDE. The webpage can be made using Adobe DreamWeaver.

Operational feasibility

This feasibility test asks if the system will work when it is developed.

Operational feasibility in this project:

7/29/2019 Tumbler 1

11/34

The proposed system offers greater level of user-friendliness. The proposed system produces best results and gives high performance. It can be

implemented easily .So this project is operationally feasible.

Economical feasibility

Economical Feasibility deals about the economical impact faced by the organization to

implement a new system. The cost of conducting a full system, including software and hardware

cost for the class of application being considered should be evaluated.

Economic Feasibility in this project:

The cost to develop the project is feasible as the softwares required are available free ofcost on the internet.

There is no additional manpower requirement. There is no additional cost involved in maintaining the proposed system.

SYSTEM DESIGN

System Design is the most creative and challenging phase in the system life cycle. Design is

the first step into the development phase for any engineered product or system. Design is a

creative process. A good design is the key to effective system. System design is a solution how to

approach the creation of a new system. System design transforms a logic representation of what

is required to do into the physical specification. The specification is converted into physical

reality during development.

SOFTWARE DESCRIPTION

This project is implemented using Java. Java goes back to 1991 when a group of sun engineers

led by James Gosling , wanted to design a small computer language that could be used for

consumer devices and named it as Green Project. Their idea was to develop a portable language

that could generate intermediate code for virtual machines. This intermediate code then can be

used on any machines that has the correct interpreter.

Java is a programming language that lets us to do almost anything we can do with traditional

programming language for distributed applications. It is platform in-dependent and having a lot

of networking features included within it. A java program can run equally well on any

architecture that has a java interpreter.

FEATURES OF JAVA

1) Encapsulation

Data Encapsulation is one of the most sticking features of OOPs. Encapsulation is the wrapping

up of data and function into single unit called class. The wrapped defines the behavior and

protects the code and data from being arbitrarily accessed by the outside world and only those

function which are wrapped in the class can access it. This type of insulation of data from direct

access by the program is called data hiding.

2) Inheritance

7/29/2019 Tumbler 1

14/34

Inheritance is the process by which objects a class can acquire the properties of objects of

another class i.e. In OOPs the concept of inheritance provides idea of reusability providing the

means of adding additional features to an existing class without modifying it. This is possible by

deriving a new class from the existing on thus the newly created class will have the combined

features of both the parent and the child classes.

3) ObjectOriented

Almost everything in java is a clear, a method or an object. Only the most basic primitive

operative and data types are at a sub-class level.

4) Data Abstraction

Data Abstraction is an act of representing essential features without including the background

details and explanation.

5) Platform Independent

Java programs are compiled with a byte code format that can be read and run by interpreters on

many platforms including Windows 95, Windows NT and later.

6) Multi-Thread

Java is inherently multi-threaded. A single java program can make many different things

processing independently and continuously.

7) High Performance

Java can be compiled on the fly with a Just-in-time compiler (JIT) to code that rivals C++ in

speed.

7/29/2019 Tumbler 1

15/34

8) Safe

Java code can be executed in an environment that prohibits it from viruses, deleting or modifying

files or otherwise performing data destroying and computer crashing operation.

9) Simple

Java has the bare bones functionally needed to implement its rich feature set.

2.2.2 Components

Java has several in-built components:

Javac : Compiler for java programs that could generate byte codes

Java : Interpreter to read and execute java byte codes.

Javap : To disassemble and debug the java bytecodes.

Javadoc: Document generator.

Javah : To write and link native codes with java programs.

SYSTEM TESTING AND IMPLEMENTATIONS

Testing is a process of executing a program with the interest of finding an error. A good test is

one that has high probability of finding the yet undiscovered error. Testing should systematically

uncover different classes of errors in a minimum amount of time with a minimum amount of

efforts.

Testing is divided into several distinct operations:

1. Unit Testing

Unit test comprises of a set tests performed by an individual program prior to the integration of

the unit into large system. A program unit is usually the smallest free functioning part of the

whole system. Module unit testing should be as exhaustive as possible to ensure that eachrepresentation handled by each module has been tested. All the units that makeup the system

must be tested independently to ensure that they work as required.

During unit testing some errors were raised and all of them were rectified and handled well. The

result was quiet satisfactory and it worked well.

2. Integration Testing

Integration testing is a system technique for constructing the program structure while at the same

time conducting tests to uncover errors associated with interfacing. The objective is to take unit

tested modules and build a program structure that has been dictated by design. Bottom-up

integration consists of unit test followed by testing of the entire system.

7/29/2019 Tumbler 1

17/34

All the modules were tested for their compatibility with other modules .The test were almost

successful. All the modules coexisted very well, with almost no bugs. All the modules were

encapsulated very well so as to not hamper the execution of other modules.

3. Validation Testing

After validation testing, software is completely assembled as a package, interfacing errors that

have been uncovered and corrected and the final series of software test; the validation test

begins. Steps taken during software design and testing can greatly improve the probability of

successful integration in the larger system.

The system was tested fully using variety of test cases and the outcome was satisfactory.

4. Recovery Testing

It is a system that forces the software to fail in a variety of ways and verifies that the recovery is

properly performed.

The test cases were chosen to fail the project and the project was able to make considerable

recovery.

5. Black Box Testing

Black box testing is done to find out the following information as shown in below:

1. Incorrect or missing functions:

There were no incorrect or missing functions found.

2. Interface errors:

There were no interface errors.

7/29/2019 Tumbler 1

18/34

3. Performance error:

There were some performance errors which were corrected and tested again.

4. Termination error:

There were no termination error

6. Test Data Output

After preparing test data, the system under study is tested using the test data. While testing the

system using test data, errors are again uncovered and corrected by using above testing and

corrections are also noted for future use.

The bugs found were corrected and then tested again.
