java - Confirming Input with multiple inputs from JFrame and JOptionPane -
i creating simulation of harmonograph, , using abstract class paint method. have made 2 separate jframes , jpanels input window asking 8 numbers each. (my main frame , panel contain main ui). have joptionpane.showconfirmdialog delay reading of variables in panel, confirmation dialog pops before panel starts.
here code:
