Join author David Gassner as he explores Java SE (Standard Edition), the language used to build mobile apps for Android devices, enterprise server applications, and more. This course demonstrates how to install both Java and the Eclipse IDE and dives into the particulars of programming. The course also explains the fundamentals of Java, from creating simple variables, assigning values, and declaring methods to working with strings, arrays, and subclasses; reading and writing to text files; and implementing object oriented programming concepts.
If you are a premium member of the lynda.com Online Training Library or if you are watching this course on a disc, you'll have access to the Exercise Files that are delivered with the course. I've copied the Exercise Files to my Desktop, but you can place them anywhere on your system. The Exercise Files for this course consists of a set of Java project files built for use in Eclipse, but the source code in these project files can be used in any Java development environment. On my system there is a file named .metadata. You won't see it on your system if you haven't opened Eclipse yet, but it will be created automatically as you work through the course's exercises.
Each chapter is represented by a folder in the main Exercise Files folder. So for example Chapter 03 has a set of four subfolders. Each of these subfolders is an Eclipse project. For example the APIDocs folder contains an Eclipse project for learning about API documentation. Within this folder you'll see a source folder that contains the actual Java source code and a bin folder where the application is being compiled. If you are working on Windows you'll also see these two files .classpath and .project.
These are files that are generated by Eclipse and that are used to configure the Eclipse project. If you are working on Mac you might not see these files in Finder but they are still there. Here is how you use each project. I'll open Eclipse, which I'll show you how to install very early in the course, and I'll show you that in this copy of Eclipse I already have four projects open. Now I am going to import another project. From the menu I'll choose File> Import>Existing Projects into Workspace.
I'll click Browse and navigate to my Exercise Files. If I choose this folder as my root folder I'll see all available projects throughout the entire folder including all of the beginning projects and all of the solution projects. Alternatively you might decide you just want to import one chapter's worth of projects. I'll choose 04_Primitives and now I'll see a much shorter list. Or you can choose to import just a single project.
This time I'll choose 04_Primitives> Booleans and click OK, and I'll see only the project in that folder. Whether you import one project at a time or a whole chapter or all the projects for the entire course it's completely up to you. When you are done with a project I recommend that you at least close it or optionally delete it from Eclipse. To close a project right-click on it in the Package Explorer and close the project. If you prefer to get rid of the project completely just select the project folder and press Delete.
You'll be prompted to remove the project from the Eclipse workspace. Don't check this option and then the project will still be there on disc. If you do check the option you are actually deleting the project and all of its source code from the disc and you'll have to extract it from the Exercise Files again. So that's a look at how to work with the exercise files for this course. If you don't have access to the Exercise Files you can use your own Java code. In each video in the course I'll show you all of the code that I am working with.
So you can either copy that code into your application or you can create your own custom code as you begin the process of learning the Java programming language.
