Java Keywords

Java contains 53 reserved words out of which 50 are keywords.

Out of 50, only 48 keywords are used and two keywords const and goto are not in use, and 3 are literals values true, false, and null.

These reserved words can not be used as identifiers.

The keyword is a reserved word that has a predefined meaning in the language, therefore, we cannot use keywords as names as a class, methods, variable names, or as any other identifier. Keywords of java are:
