Working with Strings
Strings are essential for working with text in any programming language. In Kotlin, you can join, or concatenate, strings using the + operator, but Kotlin also offers a more powerful feature: string templates. String templates let you embed variables and expressions directly inside a string using the $ symbol, making your code cleaner and easier to read. Here is how you can use both string concatenation and templates in Kotlin:
Main.kt
123456789101112131415161718package com.example fun main() { val firstName = "Ada" val lastName = "Lovelace" // String concatenation using + val fullName = firstName + " " + lastName println("Concatenated name: " + fullName) // String template with variables val greeting = "Hello, $firstName $lastName!" println(greeting) // String template with an expression val nameLength = "Your full name has ${fullName.length} characters." println(nameLength) }
This code demonstrates several ways to work with strings in Kotlin. The fullName variable uses the + operator to concatenate firstName, a space, and lastName. The greeting variable shows a string template, where $firstName and $lastName are placed directly inside the string, making the code concise and readable. The nameLength variable goes further by embedding an expression inside ${}—in this case, calculating the length of the full name. String templates let you easily include variable values or even run code within your strings.
