Summary Primitive Data Type in Java

Primitive Data Types:

• Integers

• Subtypes:

• Byte: 8-bit signed two's complement integer

, Subtypes of Integers:

• Byte:` 8-bit signed two's complement integer

• Short: 16-bit signed two's complement integer

• Int: 32-bit signed two's complement integer (most commonly used)

• Long: 64-bit signed two's complement integer

Memory Allocation and Limitations:

• Byte: -128 to 127

• Short: -32,768 to 32,767

• Int: -2,147,483,648 to 2,147,483,647

• Long: -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
