Java Data Types

Data types are utilized in Java to categorize the different types of data that may be stored within a variable. There are two categories of datatypes in Java:

• Primitive data type
• Non-Primitive data type

Primitive Data Types

There are 8 primitive data types are available in java.

• bool: Boolean datatype holds one bit of data, either true or false.
• char: char datatype is a single Unicode character that is 16 bits.
• byte: Byte datatype is an 8-bit signed two's complement integer.
• short: Short datatype is a 16-bit signed two's complement integer.
• int: It is a signed two's complement 32-bit integer.
• long: Long data type is a 64-bit signed two's complement integer.
• float: The float data type is a single-precision 32-bit IEEE 754 floating point.
• double:The double data type is a double-precision 64-bit IEEE 754 floating-point.
