Keywords and Identifiers in Java
Introduction:
Java keywords are also known as reserved words. Keywords are particular words that act as a key to a code. These are predefined words by Java so they cannot be used as identifiers.

Identifiers in Java are symbolic names used for identification. They can be a class name, variable name, method name, package name, constant name, and more.

Note: Java keywords or reserved words can not be used as an identifier.

Example:

int myNum = 100;

In the above Java statement, myNum is an identifier (User-defined), it is for identifying the variable.

String country=”India”;

In the above Java statement, country is an identifier (User-defined), it is for identifying the variable.

Java statements or steps or instructions are written using keywords, identifiers, data, and special characters.

Example:

int num =100;

In the above statement,

int is Data Type (Java keyword),

num is Identifier (variable vame),

= is assignment operator (special character) and ; (semicolon) is also a special character.

100 is data or value.
