Removing all Items from a combo box in Java

Question

I need to remove all items from the combo box

    int itemCount = combo.getItemCount();

    for(int i=0;i

        

Answer 1

You can use

this.combo.removeAllItems();

to remove all the items in JComboBox.

Answer 2

In second line:

combo.removeItemAt(0);

I think instead of 0 it should be i.

do it in reverse order as:

for(int i=combo.getItemCount()-1;i>=0;i--){
    combo.removeItemAt(i);
}

But in my case combo.removeAllItems() works fine

Answer 3

The code in the question would normally work. However, it looks like a threading issue. Another thread may be messing with the items.

However, I sugeest you should better use the removeAllItems(); method:

combo.removeAllItems();
