You should try out `outline-minor-mode'. I use it in Java files
sometimes to hide blocks of code.

For easy access, I have bound new keys to the hide- and show-subtree
commands:

 (defun my-outline-minor-mode-keys ()
   (define-key outline-minor-mode-map (kbd "<C-kp-subtract>") 'hide-subtree)
   (define-key outline-minor-mode-map (kbd "<C-kp-add>") 'show-subtree))

 (add-hook 'outline-minor-mode-hook 'my-outline-minor-mode-keys)

To use, place point at a opening bracket and type C-kp-substract (that
is the minus key on the numeric keypad).

Try it out and see if it works for you.
