  • Course details

    If you want to build applications for mobile devices, desktop computers, or the web, you need to know Java. This course provides the foundation for learning Java SE (Standard Edition), so you can build your first apps or start exploring the language on your own. Author David Gassner shows how to install Java and the IntelliJ IDEA IDE, and start working with variables, data types, keywords, and other critical language components. He also helps you control program flow with conditional logic and loops, store data with the Java Collections Framework, and understand how Java implements object-oriented coding principles such as inheritance and polymorphism.

I've opened BlueJ and I'll select Project, New Project. I'm going to place my project in the 03_06 folder, under the Chapter 03 folder of the Exercise Files. And I'll name the folder, BlueJProject. And I'll click, Create. The BlueJProject design window shows a single file and if you double-click it, you'll see that it's the project README file. A new project in BlueJ doesn't have any Java classes yet. I'll close that window, and then I'll click the New Class button, and as I've done previously, I'll name my primary class, Main, with an upper case M.
