Changing a String array for a JComboBox depending on another value in another ComboBox | Java
So what I'm trying to do is create a Combobox where when a value is changed in the first Combobox, in this case which is" FlightNumber ". Change the the String array in another Combobox in the same window, which is " Baggage " depending on which value is selected in the FlightNumber Combobox.
Every time I try to do this the program hangs after selecting a Flight number from the drop down menu.
private void jComboBox_flightNumberActionPerformed(java.awt.event.ActionEvent evt)
int number = Integer.parseInt((String)jComboBox_flightNumber.getSelectedItem());
boolean found = false;
int baggageSize = 0;
int counter;
System.out.println(this.flightList.size());
System.out.println(number);
for(counter = 0; counter < this.flightList.size()

Welcome to SO. No need to add action listener again and again. removejComboBox_baggage.addActionListener(do it once whenjComboBox_baggageis constructed). For more help post Minimal, Complete, and Verifiable example
