Java Increment Operator


Java Increment Operator ?

Increment operators are used to increase the value of the variable by one. The increment operator ++ adds 1 to its operand,

Java Increment Operator Syntax:

    ++ // increment operator

Both increment and decrement operator are used on single operand or variable, so it is called as unary operator.

Unary operators are having higher priority than the other operators it means unary operators are execute before other operators


Increment and Decrement Operators

Operator Description Example
++ Post Increment a++
-- Post Decrement a--
++a Pre Increment ++a
--a Pre Decrement --b

Java Increment Operator: Example 1



Output :

 11

Java Increment Operator: Example 2



Output :

Before x++: Value of x = 10
y = 20
After x++: Value of x = 11

Java Decrement Operator ?

Decrement operators are used to decrement the value of the variable by one. The decrement operator -- subtracts 1 to its operand,

Java Decrement Operator Syntax:

    -- // decrement operator

Java Decrement Operator: Example 1



Output :

Before x--: Value of x = 10
y = 20
After x--: Value of x = 9

Java Decrement Operator: Example 2



Output :

Before --x: Value of x = 10
y = 19
After --x: Value of x = 9
