swing - Creating a Wheel of Fortune-esque puzzle board using JPanel/JFrame Java -
i assigned free-form java coding assignment in computer science class in group , decided make wheel of fortune type game. i've been working on gui using jpaneland jframe, our online academy goes detail on, know of absolute basics. managed non-aesthetic functioning box displays individual player money , name in class named playerplate, button panel buttons need @ point during game in class called buttonpanel.
when came making letter/puzzle board puzzle displayed on 12-14-14-12 grid, experienced slew of problems. here code letterboard class i'm using try make puzzle board.

public void iterate(jtextfield[] foo) { board = foo; for(int i=0; i<foo.length; i++) { foo[i] = new jtextfield(" "); } } however, resulted in nullpointerexception error , did not instantiate a1-52 variables used in boxes. great. apologize if post , code mess.
you should have array of jtextfields , array of box or jpanel containers if need. combine them in loop.
private jtextfield[] fields = new jtextfield[text_field_count]; // const = 52 private box[] boxes = new box[suit_count]; // suit count = 4 (int = 0; < boxes.length; i++) { boxes[i] = box.createhorizontalbox(); (int j = 0; j < text_field_count/suit_count; j++) { int index = * (text_field_count / suit_count) + j; fields[index] = new jtextfield(cols); // cols = const, possibly 10 boxes[i].add(fields[index]); // add strut if desired } }
