Trying to fill multiple comboboxes by using one.

[Stevemc]

I am trying to learn java form a book, making very simple programs to see how it works. I am trying to use one combobox to fill in the other 5 with differant values. I use an action listener (works) to fill in one. I tried an array to store the combobox names so i could use a for loop, but the .addItem does not seem to work with a variable. I could be doing it all wrong.

What is the best way to do this?

I was trying to replace jcomobox1 with a a variable, so it would change comboboxes 1-5. I tried various arrays.

I am not even sure if this is the right approch.

    String [] cb  = {"jComboBox1","jComboBox2","jComboBox3","jComboBox4         ","jComboBox5"};

   public class BaseSkillListen implements ActionListener{
    public void actionPerformed(ActionEvent e){

     for(int i = 1; i < 5; i++)
         
        cb(i).removeAllItems();             
    //    jComboBox1.addItem("Skill");
    //    jComboBox1.addItem("Dist");
    //    jComboBox1.addItem("L");
    }
    }

OK, to do that, you need an array of JComboBox objects. You are creating an array of String objects, which is not what you want.

    JComboBox[] combos = new JComboBox[5];
    for (int i = 0; i < 5; i++) {
        JComboBox combo = new JComboBox();
        // do other initialization, such as cb.addItem(...)
        combos[i] = combo;
    }

Now you can access them dynamically by number -- combos[0] - combos[4].
