title: Java addressBook can not find symbol
body: <p>java can't find the symbol:variable FirstName</p>
  
  <p>I tried to save the contact information in a String array and store the array in an object so I can show the contact information in a JTable, and also be able to save the contact information.</p>
  
  <pre><code>    class addressBook implements ActionListener{
      static int num;static Object[] contact = new Object[99];
      .......
      }
      public void actionPerformed(ActionEvent e){
         if(c.equals("Save New Contact")){
           contacts CT = new contacts();
           CT.FirstName=tf[4].getText();
           CT.LastName=tf[5].getText();
           CT.EmailAddress=tf[6].getText();
           CT.Address=tf[7].getText()
           CT.PhoneNo=tf[8].getText();
           contact[num] = CT;num++;
         }else if(c.equals("View/Delete Contacts")){
           String[][] data = new String[num][5];
           for(int i=0; i&lt;num;i++){
                  data[i][0]=contact[i].FirstName;
           }
         }
      }
      class contacts implements Serializable{String FirstName; String LastName; String EmailAddress; String Address; String PhoneNo;}
  </code></pre>
