Preparing Eclipse
    
    
      In this section, you will verify that Eclipse is properly set up for Java development.
    
    
      The following is assumed:
    
    
      - 
        You are starting with a new Eclipse installation with default settings.
      
- 
        You are familiar with the basic Eclipse workbench mechanisms, such as views and perspectives.
      
      If you're not familiar with the basic workbench mechanisms, please see the
      Getting Started chapter of the Workbench User Guide.
    
    
      Verifying JRE installation and classpath variables
    
    
      - 
        If you still see the Eclipse Welcome page, click the arrow icon to begin using Eclipse.
      
- 
        Select the menu item
        
         Window > Preferences...
        to open the workbench preferences. Window > Preferences...
        to open the workbench preferences.
- 
        Select the
        
         Java > Installed JREs
        preference page to display the installed Java Runtime Environments. Confirm
        that a JRE has been detected. By default, the JRE used to run the workbench will be used to build and run 
        Java programs. It should appear with a checkmark in the list of installed JREs. We recommend that you
        use a Java SDK instead of a JRE. An SDK is designed for development and contains the source code for the
        Java library, easing debugging. Additional SDKs can be added by searching the hard drive for installed
        SDKs. To do so, simply click the Search... button and specify a root folder for the search. Java > Installed JREs
        preference page to display the installed Java Runtime Environments. Confirm
        that a JRE has been detected. By default, the JRE used to run the workbench will be used to build and run 
        Java programs. It should appear with a checkmark in the list of installed JREs. We recommend that you
        use a Java SDK instead of a JRE. An SDK is designed for development and contains the source code for the
        Java library, easing debugging. Additional SDKs can be added by searching the hard drive for installed
        SDKs. To do so, simply click the Search... button and specify a root folder for the search.
 If you work with code that does not yet use generics (as we do in this tutorial), we recommend
        that you install a Java SDK 1.4 as well, but leave the most recent version checked as default.

        preference page. 
        Confirm that option Compiler compliance level matches your default JRE version (usually 1.6). Java > Compiler
        preference page.
