# Operators

Java operators can be divided into the following four groups:

- arithmetic,
- bitwise,
- relational,
- logical.

Operators are classified as prefix, postfix, and infix.

- A prefix operator is a unary operator that precedes its operand, for example -6.
- A postfix operator is a unary operator that trails its operand, for example x++.
- An infix operator is a binary or ternary operator that is placed between the binary operator's two or the ternary operator's three operands, for example x + 5.
