Question

Say I’ve got an existing constant string:

private final static String LOREM_IPSUM = "Lorem Ipsum";

Is there a way in Eclipse to quickly extract a substring of this as another constant such that I could end up with something like:

private final static String LOREM = "Lorem";
private final static String IPSUM = "Ipsum";
private final static String LOREM_IPSUM = LOREM + " " + IPSUM;

In this particular case, two refactorings (one for LOREM and one for IPSUM) would suffice.

Answer 1

Try this sequence of steps:

1. Put your cursor after the m in Lorem, and press enter.
2. Right cursor one character.
3. Press enter.
4. Select "Lorem" and perform Refactor -> Extract Constant…
5. Select "Ipsum" and perform Refactor -> Extract Constant…
