Have Swing GUI elements, without large spaces

Have Swing GUI elements, without large spaces

My issue is, rather than the elements being on top of each other neatly,
there are huge blocks of space unnecessarily in between each element of
the gui that I use in the program.
I'm trying to have it like this:
label
textfield, button
textarea
But instead it's coming out like
label
(blotch of space)
textfield, button
(blotch of space)
textarea
when I run it. Any help is appreciated, I've really been trying to figure
it out by myself. package guiprojj;
