title: Refresh a comboBox with newly Insert/Update in SQL database - Java
body: <p>the comboBox generates the info from SQL to begin with and I select one to make an Update to or just Insert new</p>
  
  <p>Once all textFields are filled out there are 2 buttons to click which call methods that actually Insert or Update (Click to Insert, Click to Update buttons)</p>
  
  <p>Once Clicked &amp; info is added in SQL database, how do I refresh the comboBox with the information that was just added/changed?</p>
  
  <p>Ive tried comboBox.UpdateUI() > nothing
  Ive tried comboBox.setSelectedItem(variable) >  nothing</p>
  
  <p>The language is Java and I am using Swing / WindowBuilder</p>
