Java : JComboBox with IF Statement

chazat123 · December 13, 2014

I'm currently programming a pretty basic Java Currency Converter.

I decided to use ComboBoxes as I've familiarized myself with them before.

I want to receive the user's input from those combo boxes and implement them into an IF statement

How would I go about recording their input.

Many thanks,

Charlie
