Kotlin Operator Tutorial 🎯

Welcome to our deep dive into Kotlin Operators! This tutorial is designed for both beginners and intermediate learners, so let's get started. 📝

What are Operators? 📝

Operators are special symbols used in Kotlin to perform specific tasks, such as arithmetic, comparison, and assignment. They help us manipulate values and variables in our code.

Basic Operators 💡

Arithmetic Operators

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

kotlin

val a = 10
val b = 5

val sum = a + b // Addition
val difference = a - b // Subtraction
val product = a * b // Multiplication
val quotient = a / b // Division
val remainder = a % b // Modulus

💡 Pro Tip: Modulus operator (%) returns the remainder of a division operation.

Assignment Operators

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

kotlin

var myVariable = 0
myVariable += 5 // Shorthand for myVariable = myVariable + 5

Comparison Operators

Comparison operators are used to compare two values and return a Boolean (true or false) value.

kotlin

val a = 10
val b = 5

val isGreater = a > b // Greater than
val isLess = a < b // Less than
val isEqual = a == b // Equal to
val isNotEqual = a != b // Not equal to

💡 Pro Tip: Always use != for 'not equal to' instead of <> in Kotlin.

Advanced Operators 💡

Increment and Decrement Operators

These operators are used to increase or decrease the value of a variable by 1.

kotlin

var counter = 0

counter++ // Increment
counter-- // Decrement

Logical Operators

Logical operators are used to combine conditional expressions.

kotlin

val a = true
val b = false

val andResult = a && b // And
val orResult = a || b // Or
val notResult = !a // Not

Bitwise Operators

Bitwise operators perform operations on the binary representation of numbers. We won't cover them in this beginner-friendly tutorial, but they are essential for more advanced programming.
