I am trying to use a JComboBox in a GUI. The reason I want to use a JComboBox is because I don't want to write lots of code and have the use click a button to populate the drop down list and have it populate automatically based on a pre-existing method I'm using to populate a table. Now, I have a pre-existing method that populates a TableModel. That works fine. And I have another method that iterates over an ArrayList and puts the values into the TableModel. That works fine too. I want to use the JComboBox to select the value that was picked by the user in the first method. However, I don't know how to have it detect which value is selected when inside a loop that iterates over the ArrayList. Let's say the following two methods are part of an ArrayList, for simplicity. private void methodA() { tableModel.addRow(new Object[]{"1", "2", "3", "4", "5"}); } private void methodB() { // I need something like this String[] results = { "1", "2", "3", "4", "5" }; for(String name : results) { tableModel.addRow(new Object[]{name, " ", " ", " ", " "}); } I need to have the selected value returned to the ArrayList. In the next method that iterates over the ArrayList, I then need to use that selected value and display it elsewhere. I know how to do this with a button, but I want to do this programmatically. Can I somehow detect which value the user selected from inside the ArrayList or do I need to use a different method to get this information? Thanks! EDIT This is what I ended up using. I kept it simple and just had a button that created a new row in the table. I also put a check box in the first column. private void createRow() {
