HELLO MATE☺️☺️☺️☺️☺️☺️


Tokens

Tokens are the basic building blocks which can be put together to construct a Java Program. Java tokens are the smallest unit that form a Java Program.

Keywords

A keyword is a reversed word that has predefined meaning and purpose in the language you can not use keyword as identifiers. Every language has its own set of properties.

Example - into, boolean, class etc.

Identifiers

Identifiers are the name given to variables, class, array, etc. by the user.

Example - a, a5.

Literals

A literal is a notation for representing a fixed value in source code. An anonymous function is a literal function for the type.

Punctuators

A punctuator is a token that has syntactic and semantic meaning to the compiler, but the exact significance depends on the context.

$<b><i><u>✔$A voucher that can be exchanged for goods or services, typically one given as a gift or forming part of a promotional offer.

✔A keyword is an abstraction that we extrapolate from multiple search queries. A search query is the actual word or string of words that a search engine user types into the search box. As search marketers, what we target are keywords.

✔Identifier refers to name given to entities such as variables, functions, structures etc. Identifier must be unique. They are created to give unique name to a entity to identify it during the execution of the program.

✔In computer science, a literal is a notation for representing a fixed value in source code. An anonymous function is a literal for the function type. In contrast to literals, variables or constants are symbols that can take on one of a class of fixed values, the constant being constrained not to change.

✔A punctuator is a token that has syntactic and semantic meaning to the compiler, but the exact significance depends on the context.
