Basic Lab:

 1. Preparing Eclipse     
    1)Goto Eclipse from http://www.eclipse.org.
    2)Choose Eclipse IDE for java Developers and download it.
    3)Unzip eclipse to c:\eclipse\Basics folder
    4)Doubleclick eclipse.exe in c:\eclipse\Basics\eclipse
    5)Workspace type ./wksp/lab
    6)Download and install SVN according the instruction at
    http://zenit.senecac.on.ca/wiki/index.php/Basics_:_Install_Eclipse_Plugins
    7)Download JUnit from
    https://github.com/KentBeck/junit/downloads and unzip it to c:\junit4.9b2.
    8)Add junit-4.9b2 to the CLASSPATH, for example:
    classpath=.;c:\junit4.9b2\junit-4.9b2.jar;c:\junit4.9b2
    9)Test if junit is installed correct or not by typing:
    java org.junit.runner.JUnitCore org.junit.tests.AllTests
    If it display ok (508 tests), it means junit is installed correctly.
 2. Creating your first Java project
    1)Open our SVN server and export all samples to c:\ecl500samples.
    2)Click Import->existing projects, select c:\ecl500samples\w11-basics-simple,
    check copy projects into workspace.
    3)Edit Library.java by adding System.out.println("Hello"); in main.
    4)Click run, and the console will display Hello.
 3. Browsing Java elements using the package explorer
    In the left side of Eclipse, that is the package explorer.
    Use mouse to expend cs.ecl.basics.simple, I can see src and JRE System Library.
 4. Creating a Java class
    In package explorer, right click on src folder, and select new->class, type student, and click enter key.
    Actually Library.java is a class, I'm going to use it as an example instead of student.java.
 5. Editing Java elements
    In Library.java, I use source generator added following code:
   @Override
   public String toString() {
       return "Library [resources=" + resources + "]";
   }
 6. Renaming Java elements
    I changed Video.java to Audio.java by changing the interface name.
 7. Moving and copying Java elements
    I copied Audio.java and paste it in the project, and changed name to Video, then Video.java is created.
    If I use mouse to move Video.java to Media.java, it's the same as copying.
 8. Navigate to a Java element's declaration
 9. Viewing the type Hierarchy
 10.Searching the workbench
 11.Running your programs
 12.Debugging your programs
 13.Evaluating expressions
 14.Evaluating snippets
 15.Using the Java browsing perspective
 16.Writing and running JUnit tests
