3.1.1.Six categories of operatorsPrevious/Next

In Java, there are six categories of operators.

  1. Unary operators
  2. Arithmetic operators
  3. Relational and conditional operators
  4. Shift and logical operators
  5. Assignment operators
  6. Other operators
Precedence     Operator     Description                          Association
