Free Java IDE

I am only building basic applications.

I am pick products easily by searching the web but I cannot know features of each product quickly. I know this topics pops up frequently but may I have someone finds me answers to these two questions:

1) which one(s) provides features for 'automatic code completion'? I mean when I enter a dot (.), it pops up a list of attributes or methods and options for its arguments.

2) which one(s) makes creating a GUI application quicker?

Thanks.
