title: How to remove all items from jComboBox except index 0(zero)
body: <p>I have <code>jComboBox</code> and I want to refresh <code>jComboBox</code> by using <code>jComboBox.removeAllItems()</code>. But it removes all items available on <code>jComboBox</code> including <code>Select</code> which is default value. I want to keep <code>Select</code> value always on jComboBox.</p>
