Scala – Final Class Example

Here, we will demonstrate the use of the final class. If we created a final class then it cannot be inherited. To create the final class, we need to use the final keyword.

Scala code to demonstrate the example of final class

The source code to demonstrate the final class is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to demonstrate the 
// final class

final class Demo1 {
  def sayHello() {
    println("Hello from Demo1");

// Final class cannot be inherited.
// class Demo2 extends Demo1
class Demo2 {
  def sayHello() {
    println("Hello from Demo2");

object Sample {
  def main(args: Array[String]) {
    var obj1 = new Demo1();
    var obj2 = new Demo2();



Hiii from Demo1
Hello from Demo2


Here, we used an object-oriented approach to create the program. And, we created an object Sample.

Here, we created two classes Demo1 and Demo2. Both classes contain sayHello() methods. The Demo1 is a final class and it cannot be inherited.

In the main() function, we created the objects of the Demo1 and Demo2 class and called sayHello() method.
