Application Development Using Java - DIYComputerScience Course
Application Development Using Java
This is a project based course in which you will build an entire Minesweeper game
What Is A Project Based Course ? In a project based course you learn by doing. The course is structured as a large project which isbroken into many sections. In each section you will be given some code, and will have to add more code. This way you will learn Java programming by progressively building a Minesweeper game from scratch
How Large Is The Course ? This course has 13 sections, many of them containing multiple projects
Real World ComponentAcross these sections you will write code, writeunit tests, read/review code, and even fix bugs
How Does The Course Start ?You will start with an Eclipse project containing acouple of classes and test cases
How Does It Continue ?Step by step you will build an entire Minesweepergame, including a desktop version as well as a web based version.
Can You Show Me What It Will Look Like ? Minesweeper on theMinesweeper on the webdesktop
What Will I Learn In This Course ? You will learn lots of things like basics of Java programming, good programming practices, unittesting, web development using Servlets and JSP, and much more
Are There Any Prerequisites ? You will gain most from this course if you havebasic knowledge of Java syntax and you have done at least a little programming in some other language
Can You Give More DetailsAbout The 13 Sections Of This Course ? Sure, please read ahead !Remember each section may have multiple projects

Section 13 – Refactorings andEnhancements (You Decide)➲ There are still places in code which can be improved... try and make the code better !➲ There are still features that can be added to the game. Identify and implement such features depending on what you want to learn➲ And off course submit your code to the community for peer review and feedback
Happy Learning and remember you learn as muchprogramming by reading existing code, as you do by writing your own code. Be sure to read all the code which is already provided to you in the projects !
