◕ Identifier in Java.
- In Java the name we choose for a variable is called an identifier.
In large scenario, indeed the name that we choose for anything in Java is called an identifier.
◕ Rules to name a variable in Java.
- An identifier or a name can be any length.
- It must start either with a letter, an underscore (_), or a dollar sign ($).
- The rest of an identifier or a name can include any characters except those which are used as operators in Java ( such as +, -, or * ).
- Java is case sensitive, so the name of the variables Flower and flower are not same.
- We must not include Blank Space or Tabs in the middle of a variable name.
- We can't use a keyword as a name. These keywords are reserved for the operation of Java.
The example of keywords are system, out, println etc.
