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
