Stoping repeated entries in JComboBox

Hi everyone,
I am coding a program in which JComboBox displays the name of every different computer which sends it connection request.But my program enters every name in JComboBox from which it accepts request despite it is already present in the box. Please help , I have tried everything I can do.
Thanks in advance
Code snippet :

Code:

---

String hostarray[] = new String[50];
        public static int i=0;
 
 public  void addHost(String host)
          {
          check = true;
          int j;
        for( j=0; !hostarray[j].equals(null);j++)
                  {
              if(hostarray[j].equals(host))
                          {
                          check =false;
                          break;}                         
              }
      if(check)
                  {
                    hostarray[i]=host;           
              UserInterface.jComboBox1.addItem(host);
              UserInterface.jComboBox2.addItem(host);
              UserInterface.jComboBox3.addItem(host);
              UserInterface.jComboBox4.addItem(host);
              UserInterface.jComboBox5.addItem(host);
              UserInterface.jComboBox6.addItem(host);
                  }
      i++;
        System.out.println("Value of i "+i);         
    }

Combobox control already has a method remove().
If your new object is already in combobox,you can use remove method

Sorry for the cross poster but I needed the solution urgently in my project thats why i repeat.

cross-posting will often have the opposite effect of what you desire: many will avoid helping you if you do this, without at least posting the links. So my advice is if you feel you must do this, at least post links from each cross-post to another. Good luck.

Thanks for your suggestion and i will seriously follow it. But what about my solution, can anyone please solve the problem.
