I am in the middle of an android project and was trying to create a new package in it.
Well, Eclipse is not letting me to create it and is showing this error:
Invalid package name. ‘new’ is not a valid Java identifier
I never knew package name has reserved words, which we cannot use. My questions are;
- Is this an Eclipse thing? or a Java thing? I tried a pure Java project (not Android), just to check, but there also I got the same error.
- What are other reserved words that is not allowed?
- Is there any documentation about this?
Yes, this is a general Java thing.
The list of reserved words can be found here. They are:
abstract continue for new switch assert default goto package synchronized boolean do if private this break double implements protected throw byte else import public throws case enum instanceof return transient catch extends int short try char final interface static void class finally long strictfp volatile const float native super while
Documentation on the fact that reserved words can not be used in package names if found in the package naming tutorial, among other places.
The authoritative source is (as always) the Java Language Specification, specifically:
- § 3.9 Keywords and
