How to use Implicit Conversion In Scala

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

Scala
object Main {
  def main(args: Array[String]): Unit = {
    import AnotherClass._;
    val person = Person("Charlie");
    person.invokeGreet();
  }
};
case class Person(name: String) {
  def greet(): Unit = println(s"Hello, $name");
};

object AnotherClass {
  implicit class PersonOps(person: Person) {
    def invokeGreet(): Unit = person.greet();
  }
};

Output
Hello, Charlie

Explanation:

  1. We define a case class Person with a method greet().
  2. In the AnotherClass object, we define an implicit class PersonOps that adds a method invokeGreet() to Person.
  3. In the Main object, we import the implicit conversion and use it to invoke the invokeGreet() method on a Person instance.
