Primitive Data Types-
There are 8 data types predefined in Java, known as primitive data types.
1.Integer
2. Byte
3.Short
4.Long
5.Double
6.Boolean
7.Float
8.Character
1. Integer Type
The int data type can have values from -231 to 231–1 (32-bit signed two’s complement integer).
2.Byte Type
The byte data type can have values from -128 to 127 (8-bit signed two’s complement integer).
3.Short Type
The short data type in Java can have values from -32768 to 32767 (16-bit signed two’s complement integer).
4.Long Type
The long data type can have values from -263 to 263–1 (64-bit signed two’s complement integer).
5.Boolean Type
The Boolean data type has two possible values, either true or false.
6.Double Type
The double data type is a double-precision 64-bit floating-point.
7.Float Type
The float data type is a single-precision 32-bit floating-point.
8.Char Type
The char
data type is used to store a single character. The character must be surrounded by single quotes, like 'A' or 'c'.
