Question

This seems to be a stupid question since Java does short circuit, but I remembered how Android doesn’t quite use Java in the same sense as I assume, so say in this bit of code I wrote:

... code omitted ...
else if (mimeType.equals("application/x-tar")
     || mimeType.equals("application/x-rar-compressed")
     || mimeType.equals("application/stuffit")
     || mimeType.equals("application/zip")
     || mimeType.equals("application/x-gzip"))

…would it be better for me to put the more common things (zip/rar) before the less common things (tarballs/gzip)?

The fact that I wasn’t able to find a similar question on SO probably gives me the answer to this, but better safe than sorry.

Answer 1

Short circuiting is supported with ||.

If you are trying to optimize this case you should try putting each value in a static Set and then check to see if typeSet.contains(mimeType).
