How do you split and unsplit a window/view in Eclipse IDE?

Question

How do you split a window/view in Eclipse IDE? I want to edit code while viewing the different code in the same file.

If there is a trick to open the same file twice

Answer 1

I tried the above solutions in Eclipse Luna 4.4.1 but couldn't open two (or multiple editor windows for different files side by side).

Simplest Solution:

1. Open all files you want in a single window.
2. Drag the tab of each of the files to right or to the left, eclipse will automatically display a split screen display and will split the editor into two windows once you leave the mouse button.
3. repeat for each file/tab.

Happy Coding!
