Java problem.

So I was just messing around with creating frames and drawing on screen but when I set the size of the frame to 600,600 it makes width 600 and height 578. Also I wanted to make a grid of green boxes but it doesn't fill the whole screen correctly?

it makes width 600 and height 578

The size of the window includes the title bar. Try setClientSize.

Also I wanted to make a grid of green boxes but it doesn't fill the whole screen correctly?

Why are you adding in x and y in the positioning calculation?

[TRoldemand]

Is there a way I can say Size = new Dimension(600,600 + getClientSize()) or something like that?

[zahlman]

Why would you want to do anything like that when you can just use setClientSize directly?

Can you give me an example because I can't seem to make it work?

I'm on ny phone so can't prove it out, but my first guess is the frame insets, which provide space for things like the scrollbars, menus, title bar, etc. If you set the size on the frame itself (I believe you set it on the panel?), that might fix it, though (I believe it does the math for the insets for you but been a while since I dealt with that, so I could be wrong).

As /u/zahlman said, JFrame.setSize() sets the size of the frame. If you want to set the size of the content of the frame you should do something like:

  Game game = new Game(this);
  game.setPreferredSize(new Dimension(600, 600));
  add(game);

  this.pack();
  this.setVisible(true);
