Kotlin Operators Reference 🎯

Welcome to the Kotlin Operators Reference! In this comprehensive guide, we'll explore various operators available in Kotlin, their uses, and examples to help you become a proficient Kotlin developer. Let's dive right in!

Arithmetic Operators 💡

Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication, division, and modulus.

Addition (+)

Adds two operands together.

kotlin
val a = 5 val b = 3 val sum = a + b // sum = 8

Subtraction (-)

Subtracts one operand from another.

kotlin
val a = 5 val b = 3 val difference = a - b // difference = 2

Multiplication (*)

Multiplies two operands together.

kotlin
val a = 5 val b = 3 val product = a * b // product = 15

Division (/)

Divides one operand by another.

kotlin
val a = 10 val b = 2 val quotient = a / b // quotient = 5.0

Modulus (%)

Returns the remainder of the division operation.

kotlin
val a = 10 val b = 3 val remainder = a % b // remainder = 1

Assignment Operators 📝

Assignment operators are used to assign a value to a variable.

Assignment (=)

Assigns the right operand to the left operand.

kotlin
val a = 5

Compound Assignment

Performs an operation and assigns the result back to the variable.

kotlin
val a = 5 a += 3 // a = 8

Comparison Operators 📝

Comparison operators are used to compare two operands.

Equality (==)

Checks if two operands are equal.

kotlin
val a = 5 val b = 5 if (a == b) println("a is equal to b")

Inequality (!=)

Checks if two operands are not equal.

kotlin
val a = 5 val b = 6 if (a != b) println("a is not equal to b")

Greater Than (>)

Checks if the left operand is greater than the right operand.

kotlin
val a = 7 val b = 5 if (a > b) println("a is greater than b")

Less Than (<)

Checks if the left operand is less than the right operand.

kotlin
val a = 3 val b = 5 if (a < b) println("a is less than b")

Greater Than or Equal (>=)

Checks if the left operand is greater than or equal to the right operand.

kotlin
val a = 7 val b = 5 if (a >= b) println("a is greater than or equal to b")

Less Than or Equal (<=)

Checks if the left operand is less than or equal to the right operand.

kotlin
val a = 3 val b = 5 if (a <= b) println("a is less than or equal to b")
