What are the 3 primitive data types?

In the Java type system, there are three further categories of primitives:

There are 7 primitive data types: string, number, bigint, boolean, undefined, symbol, and null . Most of the time, a primitive value is represented directly at the lowest level of the language implementation. All primitives are immutable, i.e., they cannot be altered.

Primitive data types are predefined data types such as Byte, SByte, Boolean, Int16, UInt16, Int32, UInt32, Char, Double, Int64, UInt64, Single, etc. Whereas non-primitive data types are user-defined data types such as enum, class, etc.

Primitive data types – includes byte , short , int , long , float , double , boolean and char . Non-primitive data types – such as String , Arrays and Classes (you will learn more about these in a later chapter)
