Kotlin Assignment Operator

Kotlin Assignment Operator

Kotlin Assignment Operator assigns the right operand, usually a value or an expression, to the left operand, usually a variable or constant.

Syntax

The syntax to use Assignment operator is

x = value

where

  • x is the variable name
  • = is the symbol used for Assignment operator
  • value is the value that we would like to assign to variable x

Examples

Assign variable message with the string value “Hello World”

In the following program, we take a variable: message, and assign this variable with a value "Hello World", using Assignment operator.

Kotlin Program

fun main() {
    var message = "Hello World"
    println(message)
}

Output

Hello World

Assign a new value to a variable

We can also assign a new value to a variable using Assignment operator.

In the following program, we have initialised the variable message with a value "Hello World". Then we assign a new value, say "Hello User" to the message variable using Assignment operator.

Kotlin Program

fun main() {
    var message = "Hello World"
    message = "Hello User"
    println(message)
}

Output

Hello User
