Identifying problems in your code 
 In this section, you will review the different indicators for identifying 
  problems in your code. 
Build problems are displayed in the  Problems view and annotated in the vertical
ruler of your source code. 
  -  Open junit.framework/TestCase.java in the editor from the 
    Package Explorer view. 
-  Add a syntax error by deleting the semicolon at the end of the package
    declaration in the source code. 
       
 
-  Click the Save button. The project is rebuilt
    and the problem is indicated in several ways: 
    
      -  In the  Problems view, the problems are listed, 
-  In the Package Explorer view, the Type Hierarchy or the Outline view, 
        problem ticks appear on the affected Java elements and their parent elements, 
      
-  In the editor's vertical ruler, a problem marker is displayed near the affected line, 
      
-  Squiggly lines appear under the word which might have caused the error, and
-  The editor tab is annotated with a problem marker. 
   
 
-  You can hover over the marked word in the editor to view a description 
    of the problem. You can also hover over the problem markers in the vertical or overview rulers. 
       
 
-  Click the Close ("X") button on the editor's tab to 
    close the editor. 
-  In the  Problems view, select a problem in the list. Open its context menu 
    and select Go To. The file is opened in the editor at the location of the 
    problem. 
       
 
-  Correct the problem in the editor by adding the semicolon. Click 
    the Save button. The project is rebuilt and the problem indicators disappear. 
-  In the Outline view, select the method getName(). The editor will 
    scroll to this method. 
-  On the first line of the method change the returned variable fNametofTestName. While you type, a problem highlight underline appears 
    on fTestName, to indicate a problem. Hovering over the highlighted problem 
    will display a description of the problem and applicable quick fixes.
-  On the marker bar a light bulb marker appears. The light bulb signals that 
    correction proposals are available for this problem. 
       
 
-  Click to place the cursor onto the highlighted error, and choose Quick Fix 
    from the Edit menu bar. You can also press Ctrl+1 or left click the light 
    bulb. A selection dialog appears with possible corrections. 
       
 
-  Select 'Change to fName' to fix the problem. The problem highlight 
    line will disappear as the correction is applied. 
-  Close the file without saving. 
-  You can configure how problems are indicated on the
