Java Unary Operators | Java Tutorial for Beginners | G C Reddy |

Java Unary Operators: Unary Operators in Java are used to perform increment, and decrement operations, these operators require single operand only.

Operators in Programming: Operators are used to perform operations on variables and values. These operations can be Mathematical, Assignment, Comparison, Logical etc…

Operations on Variables and Values: We can use Operators on Variables and Values to perform operations.

Operators in Java:
We have several categories operators in Java, Arithmetic Operators, Unary Operators, Assignment Operators, Comparison Operators, and Logical Operators etc…

Some people call that Unary Operators are part of Arithmetic Operators, Yes It may be sub category of Arithmetic Operators.

Java Unary Operators:
The unary operators require only one operand; they perform various operations such as incrementing/decrementing a value by one, negating an expression, or inverting the value of a boolean.

+ Unary plus operator; indicates positive value (numbers are positive without this, however)
– Unary minus operator; negates an expression
++ Increment operator; increments a value by 1
— Decrement operator; decrements a value by 1
! Logical complement operator; inverts the value of a boolean
