Java Naming Conventions
Java uses CamelCase (It consists of compound words or phrases
such that each word or abbreviation begins with a capital letter or first word
with a lowercase letter, rest all with capital.) as a practice for writing
names of methods, variables, classes, packages and constants.
1. Classes and Interfaces ::
Class names should be nouns, in mixed case with the first letter of each internal word capitalized. Interfaces name should also be capitalized just like class names.
Use whole words and must avoid acronyms and abbreviations.

2. Methods ::
Methods should be verbs, in mixed case with the first letter lowercase and with the first letter of each internal word capitalized.

3. Variables ::
Variable names should be short yet meaningful.
Should not start with underscore(‘_’) or dollar sign ‘$’ characters.
Should be mnemonic i.e, designed to indicate to the casual observer the intent of its use.
One-character variable names should be avoided except for temporary variables.
Common names for temporary variables are i, j, k, m, and n for integers; c, d, and e for characters.

4. Constant variables ::
Should be all uppercase with words separated by underscores (“_”).
There are various constants used in predefined classes like Float, Long, String etc.

5. Packages ::
The prefix of a unique package name is always written in all-lowercase ASCII letters and should be one of the top-level domain names, like com, edu, gov, mil, net, org.
Subsequent components of the package name vary according to an organization’s own internal naming conventions.
