In Java, there are eight primitive data types. These are the basic data types that you can use to declare variables. They are:
Byte: An 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). Example: byte b = 100;
Short: A 16-bit signed two's complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive). Example: short s = 10000;
Int: A 32-bit signed two's complement integer. It has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive). Example: int i = 100000;
Long: A 64-bit signed two's complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). Example: long l = 100000L;
Float: A 32-bit IEEE 754 floating point. Example: float f = 234.5f;
Double: A 64-bit IEEE 754 floating point. Example: double d = 234.5;
Boolean: Represents one bit of information. It can have only one of two values: true or false. Example: boolean b = true;
Char: A single 16-bit Unicode character. Example: char c = 'A';
These primitive data types are the building blocks for all other data types in Java, including arrays, classes, and interfaces.
