As mentioned earlier, static does not exist in Scala. You cannot do static imports and neither can you cannot add static methods to classes. In Scala, when you define an object with the same name as the class and in the same source file, then the object is said to be the companion of that class. Functions that you define in this companion object of a class are like static methods of a class in Java:

class HelloCity(CityName: String) {
  def sayHelloToCity = println("Hello, " + CityName + "!") 
}

This is how you can define a companion object for the class hello:

object HelloCity { 
  // Factory method 
  def apply(CityName: String) = new Hello(CityName) 
}

The equivalent class in Java would look like this:

public class HelloCity { 
  private final String CityName; 
  public HelloCity(String CityName) { 
    this.CityName = CityName; 
  }
  public void sayHello() {
    System.out.println("Hello, " + CityName + "!"); 
  }
  public static HelloCity apply(String CityName) { 
    return new Hello(CityName); 
  } 
}

So, lot's of verbose in this simple class, isn't there? The apply method in Scala is treated in a different way, such that you can find a special shortcut syntax to call it. This is the familiar way of calling the method:

val hello1 = Hello.apply("Dublin")

Here's the shortcut syntax that is equivalent to the one earlier:

 val hello2 = Hello("Dublin")

Note that this only works if you used the apply method in your code because Scala treats methods that are named apply in this different way.
