I need to populate a JComboBox with an ArrayList. Is there any way to do this?

String[] array = arrayList. toArray(new String[arrayList. size()]); JComboBox comboBox = new JComboBox(array); Alternatively, you can also maintain strong typing by just using a for loop.
ArrayList<String> a = new ArrayList<String>(); a. add(0, "hahah"); a. add(1, "bleeeee"); a. add(5, "cleeeee"); //this makes an error, when I change index to 2, it works JComboBox supplierComboBox = new JComboBox(a.
The enhanced for loop (sometimes called a "for each" loop) can be used with any class that implements the Iterable interface, such as ArrayList .
Use the toArray() method of the ArrayList class and pass it into the constructor of the JComboBox
See the JavaDoc and tutorial for more info.
