Java variable naming conventions
For variables, the Java naming convention is to always start with a lowercase letter and then capitalize the first letter of every subsequent word. Variables in Java are not allowed to contain white space, so variables made from compound words are to be written with a lower camel case syntax.

Here are three examples of variables that follow the standard Java naming convention:
firstName
timeToFirstLoad
index

As the name suggests one stands for marks while the other is for an answer be it of any e do not mind.
Constant variables
* Should be all uppercase with words separated by underscores (“_”).
* There are various constants used in predefined classes like Float, Long, String etc.

Reserved Words

Any programming language reserves some words to represent functionalities defined by that language. These words are called reserved words. They can be briefly categorized into two parts: keywords(50) and literals(3). Keywords define functionalities and literals define value. Identifiers are used by symbol tables in various analyzing phases(like lexical, syntax, and semantic) of a compiler architecture.
