Can you list the main primitive data types available in Java?

In Java, there are 8 primitive data types:

• byte — 8-bit signed integer (-128 to 127)
• short — 16-bit signed integer (-32,768 to 32,767)
• int — 32-bit signed integer (-2^31 to 2^31-1)
• long — 64-bit signed integer (-2^63 to 2^63-1)
• float — 32-bit single-precision floating point number
• double — 64-bit double-precision floating point number
• char — 16-bit Unicode character
• boolean — logical type, takes values true or false

These types are used to store simple values and differ from reference types (objects).
