Can Eclipse convert if statements to if-else-if

I'm using Java with Eclipse.

In my application, one code snippet is there which is the long series of multiple if statements.

Recently I had to work upon that code & I found that these multiple if statements can be converted to if-else-if ladder.

Now converting this to if-else-if ladder manually is somewhat cumbersome.

Is there some short cut in Eclipse that I can use to do so?

After a long search I finally found the short cut in Eclipse.

I selected all the if statements, pressed Ctrl+1 (Right Click & selected Quick Fix).

It gave me an option "Join if sequence in if-else-if", which does exactly what I want.

  • Use Find/Replace Dialog.

  • Replace all }\s*if with }else if.

  • Enable "Regular Expressions".

  • You can select the lines you want and enable "Selected lines".

Since it might not be the same logic, I don't think that Eclipse has that feature. I do know that IntelliJ have Inspections covering those kind of issues, so maybe a plugin doing code inspections can help you refactor.

Secondly, if it can be converted to if else if, then it might also be convertable to switch case depending on what variable you are looking at, and if it's the same. Also available on strings since java 7. It might also be refactorable to do switch on enums.

Find & Replace all "if" with "else if", then fix the compiler error on the first one by deleting the "else". Make sure you're not accidentally changing anything else that you shouldn't!
