In Java, i++ is unary operator or arithmetic operator?

Question

I have searched the web and it gives me a divide answer. Some said it is only an unary operator and some said it is an arithmetic operator. Thanks

Answer 1

These classifications don't contradict each other.

++ is an unary operator, as it applies to a single operand.

++ is also an arithmetic operator, as it applies to a number and performs an arithmetic operation (incrementing the number by one).

Answer 2

I think it won't be a mistake to call i++ both Arithmetic and Unary Operator.

However, Oracle doc here distinguishes and classifies ++ as Unary operator.
