What Is Object In Scala? Is It A Singleton Object Or Instance Of A Class? |
|
Answer» Unlike Java, Scala has two MEANINGS about ‘object’. Don’t get confuse about this, I will explain it clearly. In Java, we have only one MEANING for object that is “An instance of a class”. Like Java, the first meaning of object is “An instance of a class”. VAL p1 = new Person("Scala","Java") Second meaning is that object is a keyword in Scala. It is USED to define Scala Executable programs, Companion Objects, Singleton Objects etc. Unlike Java, Scala has two meanings about ‘object’. Don’t get confuse about this, I will explain it clearly.
