5.2.1 Package Name

The package name is all lowercase letters, which simply connect consecutive words in the previous (without underlining).

For example: Use com.example.deepspaceinstead of com.example.deepSpace or com.example.deep_space.

5.3 Camel-style naming method

Name starting with a phrase:

• Converts a phrase to a pure ASCII code and removes any single quotation marks. For example: "Müller ' s Algorithm" will become "Muellers algorithm".
• Divide the result into words, separated by spaces or other punctuation (often hyphens).
• Recommendation: If a word already has a common hump representation, split it up by its composition (such as "AdWords" will split into "ad words"). It is important to note that "IOS" is not a real hump representation, it violates the Convention, so this recommendation does not apply to it.
• lowercase all letters (including abbreviations) and capitalize the first letter of a word:
• Capitalize the first letter of each word to get a big hump-named (uppercamelcase)
• In addition to the first word, the first letter of each word is capitalized to get the small hump-type name (Lowercamelcase)
• Finally, link all the words together to get a representation.

Example

Prose Form	Correct	Incorrect
"XML HTTP Request"	XmlHttpRequest	XMLHTTPRequest
"New Customer ID"	newCustomerId	newCustomerID
"Inner Stopwatch"	innerStopwatch	innerStopWatch
"Supports IPV6 on IOS?"	supportsIpv6OnIos	supportsIPv6OnIOS
"YouTube Importer"	YouTubeImporter YoutubeImporter*
