Can we use camel case in java package naming? [duplicate]

Question

For example: Which of the following package names is correct?

com.google.payrolldivision;

or

com.google.payrollDivision;

Please just answer the question without beating around the bush?

Answer 1

Please just answer the question

OK, then taking your question as a "a xor b", the answer is

com.google.payrolldivision;

as per https://docs.oracle.com/javase/tutorial/java/package/namingpkgs.html.

However, your title and post ask two very different questions, so it's hard to "just answer the question".

Answer 2

According to the Oracle webpage, you should write your package name in lowercase.

Package names are written in all lower case to avoid conflict with the names of classes or interfaces.
