In this tutorial you will learn about Strings via simple step by step examples.
Example 1: Strings
Let us look at a simple Strings example written in Kotlin Programming Language. Follow the following steps:
Step 1: Create Project
- Open your favorite Kotlin IDE.
- In the menu go to
File --> Create New Project
.
Step 2: Add Dependencies
No dependencies are needed for this project.
Step 3: Write Code
Our code will comprise the following Kotlin files:
Strings.kt
- In your editor or IDE, create a file known as
Strings.kt
. - Then add the following code:
(a). Strings.kt
package Strings
fun main(args : Array<String>) {
var plato1 = "Wise men speak because they have something to say; Fools because they have to say something."
//This is a single line string
println("I love ancient philosophy.")
//Use triple quote """ to go multi line. This also means that you can use double quote " freely in the string.
//This demonstrate template expression. Pretty neat huh. You can use ${ } to show any arbitrary expression
println("""My favorite quote is by '$plato1' although at ${plato1.length} characters long, it is not compact.
He is also a skeptic on love "${platoOnLove()}. He is wrong, love is as simple as 1 + 1 = ${1 + 1 }."
""")
}
fun platoOnLove() : String {
return "Love is a serious mental disease."
}
/* what's next? try Variables\Variables.kt to learn about immutable/mutable variable declarations */
Step 4: Run
Copy the code, build and run.
