Something like this, perhaps:

RewriteEngine on
RewriteRule ^category\.php\?id=1$ php/1 [L]
RewriteRule ^category\.php\?id=2$ java/2 [L]
RewriteRule ^category\.php\?id=3$ ruby/3 [L]
RewriteRule ^category\.php\?id=4$ perl/4 [L]

Put this code in your .htaccess file:

Options +FollowSymlinks -MultiViews
RewriteEngine on

RewriteRule ^(php|java|ruby|perl)/([0-9]+)/?$  /category.php?id=$2 [L,NC,QSA]
