A simple project that uses the basic principles of OOP in Java

Question

Hi everyone. I believe that we will never learn any programming language in depth until we apply all the theories on a real world application. And I kinda suck at the creativity thing :c So I would want to ask for ideas on any simple application that the basic principles in OOP (inheritance, interface, encapsulation, and polymorphism) can be best applied.

Thanks, nef

Answer 1

Anything with a graphical user interface tends to utilise all the OOP principles pretty quickly.

• Event listeners implement some form of interface
• Components inherit from other components
• Data structures / models need to be encapsulated
• Different GUI components can be plugged in via polymorphism

As a project, what about implementing a custom Swing GUI component, for example a chess board?

If you find that too easy, then you can always write the AI so that it plays against you....

Answer 2

if you use netbeans, you found example project. Try to understand from the project. And then read name of attribute or method. And then image work of method like behavior work. I think this is simple ways to understand OOP in my ways.

Answer 3

Try make a project that the user interact with a database. You will have to start making a module that handles the db part, a module that interacts with the user and something that correlates the two. For example an ordering system.
