Method call in Scala

In Scala, we call a method in a class by using the dot notation on an instance or object of the class. Here is an example:

class MyClass {
  def greet(name: String): Unit = {
    println(s"Hello, $name!")
  }
}
// Create an instance of MyClass

val myObj = new MyClass()
// Call the greet method on the instance

myObj.greet("John")

In this example, we define a MyClass with a method greet that takes a String parameter name and prints a greeting message. We then create an instance of MyClass called myObj using the new keyword. Finally, we call the greet method on myObj by using the dot notation with the method name and passing an argument of "John".

The output of this program will be:

Hello, John!
