Printing Variables and Values in Kotlin

Syntax

// String
println("Print plan String");

// Printing Variables
println("Print Variables $variable");

// Expressions
println("Print { $variable + $variable}");

Printing Variables,Expression Kotlin Example Program

// Print Variables,Expression in Kotlin example program
// Data Output Kotlin Programs, Basic Kotlin Programs

fun main(args: Array < String > ) {
    
    val num = 100
    //Print Values using print
    println("Print Plain String ")
    
    //Printing Variables
    println("num Value is $num ")
    
    //Expressions 
    println("num + num Value is ${num+num} ")
}

Sample Output

Print Plain String 
num Value is 100 
num + num Value is 200

How It Works

Here is a step-by-step walkthrough of how the Kotlin program for Printing Variables and Values in Kotlin runs, line by line:

1. fun main(args: Array < String > ) { — defines a function used by the program.
2. val num = 100 — declares or assigns a value the program uses.
3. println("Print Plain String ") — writes a line of output shown in the sample output.
4. println("num Value is $num ") — writes a line of output shown in the sample output.
5. println("num + num Value is ${num+num} ") — writes a line of output shown in the sample output.

After running it, compare your console output with the Sample Output above. Try changing the values and re-running the program to see how the result changes — experimenting is the fastest way to understand the logic.
