Java Naming conventions
Java naming convention is a rule to follow as you decide what to name your identifiers such as class, package, variable, constant, method, etc.

All the classes, interfaces, packages, methods and fields of Java programming language are given according to the Java naming convention. If you fail to follow these conventions, it may generate confusion or erroneous code.
