Eclipse - Same .Java file in split view?

Question

Perhaps this is a trivial question, however it\'s something that is seriously annoying me. I\'m editing someone\'s program at the minute and one of their .java

Lars Vogel just announced (December 2013) in "Split editor implemented in Eclipse M4 Luna" that is is now possible possible!

Split editor implemented in Eclipse M4 Luna 4.4

This solves one of the oldest and most upvoted Eclipse bug: Bug 8009.

The split editor functionality has been developed in Bug 378298, and will be available as of Eclipse Luna M4. The Note & Newsworthy of Eclipse Luna M4 will contain the announcement.
Current shortcut for splitting is:

• Ctrl + _ for split horizontally, and
• Ctrl + { for split vertically.

As commented by mahesha999, there is a clone option in menu Window > Editor > Clone which opens separate cloned window/tab (instead of split view inside the same tab) that can be dragged to the 2nd monitor.
