One of the best feature of Eclipse is that you can learn while coding as it shows the documentation right in the editor by hovering over an API. I really missed that feature in Intellj. As I am new to this platform, may be there is a trick to get that feature that I am not aware of. I appreciate any tip regarding this.

You can view documentation by placing the caret at a symbol and pressing Ctrl+Q or selecting View | Quick Documentation from the main menu.
View Javadocs in the editorHover the mouse over the necessary symbol in the editor. Place the caret at the symbol and press Ctrl+Q (View | Quick Documentation). Press Ctrl+Q again to open this documentation in the Documentation tool window.

Simple docs will appear if you hold ctrl when you hover. To make proper docs appear just on hover (like eclipse) in IntelliJ v14.0:
File > Settings... > Editor > General > [Other]
Then at the very bottom there is an option: "Show quick documentation on mouse move":
The docs will now appear on hover:
