How to use Companion Object In Scala

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

Scala

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

object AnotherClass {
  def main(args: Array[String]): Unit = {
    val person = Person("Alice");
    person.greet()
  }
};

Output

Hello, Alice

Explanation:

We define a case class Person with a method greet() that prints a greeting message.
In the AnotherClass object, we create an instance of Person and invoke the greet() method.
