java - How do you make a program wait for user input? -

i'd use variable column_input later.

public static void playgame(){        btnnewbutton.addactionlistener(new actionlistener() {         public void actionperformed(actionevent e) {             string input = textfield.gettext();             chosen_column = integer.parseint(input);             textfield.settext(null);         }     }); } 

looks need single piece of data. easiest solution use joptionpane. can prompt user input.
