    <p>I have several objects which are assigned attributes based on user input. I then store those objects in a vector, and then write that vector to a file but on deserializing the stored vector, only the first object is read. Here's the code that i have so far:</p> <pre><code> public Vector&lt;Cases&gt; registerCase() { Vector&lt;Cases&gt; casesVector = new Vector&lt;Cases&gt;(10, 2); Scanner myCase = new Scanner(System.in); Scanner userChoice = new Scanner(System.in); System.out.println("HOW MANY CASES DO YOU WANT TO REGISTER?"); int count = userChoice.nextInt(); for (int i = 0; i &lt; count; i++) { Cases newCase = new Cases(); System.out.println("Enter the case name: "); newCase.caseName = myCase.nextLine(); System.out.println("Enter the client's name: "); newCase.client = myCase.nextLine(); System.out.println("Enter the case type: "); newCase.caseType = myCase.nextLine(); if((newCase.caseType.equals("Major")) || newCase.caseType.equals("major")){ newCase.closedCaseRevenue = majorCasePrice; }else { newCase.closedCaseRevenue = (int) (0.75 * majorCasePrice); } casesVector.add(newCase); } try{ // Open a file to write to, named SavedCases.sav. FileOutputStream saveFile = new FileOutputStream("SavedCases.sav", true); ObjectOutputStream save = new ObjectOutputStream(saveFile); save.writeObject(casesVector); save.close(); } catch(Exception exc){ exc.printStackTrace(); } Vector&lt;Cases&gt; comVector = new Vector&lt;Cases&gt;(); try{ FileInputStream saveFile = new FileInputStream("SavedCases.sav"); ObjectInputStream save = new ObjectInputStream(saveFile); comVector = (Vector&lt;Cases&gt;) save.readObject(); System.out.println("The size of the vector is: " + comVector.size()); save.close(); // This also closes saveFile. } catch(Exception exc){ exc.printStackTrace(); } for (Cases law_case : comVector) { System.out.println("Name: " + law_case.caseName); System.out.println("Client: " + law_case.client); System.out.println("Case Type: " + law_case.caseType); System.out.println("Case State: " + law_case.caseState); System.out.println("Case Revenue: " + law_case.closedCaseRevenue); System.out.println(); } return casesVector; } </code></pre>

    1. COWrite out the length of the vector before you output it to make sure it's what you expect it is. Also write out count. What number of cases are you using?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
