swing - Java getting the wrong number of jbuttons in grid layout -

so i'm new java , im new swing.

i've got 80 x 80 array thats going used maze. need gui have 80 x 80 buttons can tied values in array.

i cant figure out why i'm getting 5 or 6 large buttons code. if can tell me how can work thank in advance because i'm stumped.

just run , you'll see mean...also guess i've not figured out how change color of buttons , changed background color instead.

heres code:

public static void draw() {      jframe f = new jframe();     f.settitle("maze");     f.setsize(800, 800);     f.setvisible(true);     f.setdefaultcloseoperation(exit_on_close);      jpanel c = (jpanel)f.getcontentpane();     gridlayout gridlayout = new gridlayout();     c.setlayout(gridlayout);     for(int =0;i<80;i++){         for(int j =0;j<80;j++){             jbutton b = new jbutton();             c.add(b, i,j);             b.setsize(10, 10);             b.setopaque(true);             b.setbackground(color.red);         }     }   }  } 

1. 80 * 10 > f.setsize(800, 800); , code not possible fit in fullhd monitor

2. 2. use f.pack() instead of f.setsize(800, 800);

3. f.pack() , f.setvisible(true); (could main issue) should last code lines in non_static , renamed !public void drawme() {!, because draw() reserved word for/in java api

4. c.add(b, i,j); should last code line (logical ordering),

5. c.add(b, i,j); set row , columns gridlayout instead of injecting jbutton virtual grid in gridlayout

• make me sense (starting numbers of elements)
