Application Development Using Java - DIYComputerScience Course
- 1. Application Development Using Java
- 2. This is a project based course in which you will build an entire Minesweeper game
- 3. What Is A Project Based Course ? In a project based course you learn by doing. The course is structured as a large project which is broken 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
- 4. How Large Is The Course ? This course has 13 sections, many of them containing multiple projects
- 5. Real World Component Across these sections you will write code, write unit tests, read/review code, and even fix bugs
- 6. How Does The Course Start ? You will start with an Eclipse project containing a couple of classes and test cases
- 7. How Does It Continue ? Step by step you will build an entire Minesweeper game, including a desktop version as well as a web based version.
- 8. Can You Show Me What It Will Look Like ? Minesweeper on the Minesweeper on the web desktop
- 9. What Will I Learn In This Course ? You will learn lots of things like basics of Java programming, good programming practices, unit testing, web development using Servlets and JSP, and much more
- 10. Are There Any Prerequisites ? You will gain most from this course if you have basic knowledge of Java syntax and you have done at least a little programming in some other language
