How to use Inheritance In Scala

Below is the Scala program to access a case class method from another class using inheritance:

Scala

case class Person(name: String) {
  def greet(): Unit = println(s"Hello, $name")
};

class AnotherClass extends Person("Bob") {
  def invokeGreet(): Unit = greet()
};

object Main {
  def main(args: Array[String]): Unit = {
    val anotherClass = new AnotherClass;
    anotherClass.invokeGreet()
  }
};

Output

Hello, Bob

Explanation:

We define a case class Person with a method greet().
The AnotherClass class extends Person and defines a method invokeGreet() that calls the greet() method.
In the Main object, we create an instance of AnotherClass and invoke the invokeGreet() method.
