Order of import statements in java [closed]

Question

Just to know. Which is the proper way of ordering import statements? Also which has more readability?

like,

• External classes (like java.util.List) and then internal package
  classes.
• Just in alphabetical order

Thanks in advance.

Answer 1

I prefer this :

1) First group imports based on external and internal APIs 2)Alphabetically within each group

Answer 2

Im not sure if there is a standard. But some projects such like android use the following rule.

1. First import project specific files (android)
2. Second comes the third party files and library.
3. The java standard api files.

Each group is seperated by an extra line. And each group has their imports in alphabetical order.

AFAIK these are based on our preference.
