    <p>I'm trying to write a program where the user can: 1) Add a person to the contact (name, phone, email), 2) Remove a person from the contacts, 3) Read all from contact.</p> <p>The Way I'm doing this is I'm asking for the user for their choice and respectively does whatever. For writing, I simply write an object to the file. For removing, I think I'll be asking the user for "last name" which will be used as the KEY (since I'm using a TreeMap)and will remove the value (object) at the key.</p> <p>So I'm having a problem with reading here. I'm trying to read the object like so:</p> <pre><code>public void readContact() { TreeMap&lt;String, Contact&gt; contactMap = new TreeMap&lt;String, Contact&gt;(); try { ObjectInputStream in = new ObjectInputStream(new BufferedInputStream( new FileInputStream(file))); while( in.available() &gt; 0 ) //This line does NOT read { Contact c = (Contact)in.readObject(); contactMap.put(c.getLastName(), c); } for(Map.Entry contact : contactMap.entrySet() ) { Contact con = contactMap.get( contact.getKey() ); System.out.println( con.getLastName() + ", " + con.getFirstName() + ": " + con.getPhoneNumber() + "\t" + con.getEmail()); } } catch(Exception e) { System.out.println("Exception caught"); } } </code></pre> <p>Please do not suggest doing something like <code>while(true)</code> until I get the <code>EOFException</code> because:</p> <ol> <li>that isn't what exception handling is for I believe</li> <li>I still have more things to do after this so I can't have the program terminating'</li> </ol>

    2. COErr, wait... You iterate over the map's entry set and you use `.get()` on the map to get the value?

    3. COHandling an exception WILL terminate the program because once an exception is thrown, whatever is inside the "catch" block will be executed and the program will terminate.... For example, if I call the readContact() method from some other method and try to do something, it will terminate at the readContact() method and so I won't be able to do anything else.

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.
