Likewise, people ask, what is difference between object and class in Kotlin?
Kotlin introduces the concept of an object on top of that. Whereas a class describes structures that can be instantiated as and when desired and allows for as many instances as needed, an object instead represents a single static instance, and can never have any more or any less than this one instance.
Subsequently, question is, what is the difference between object block and companion object code block in Kotlin? A Companion object is initialized when the class is loaded (typically the first time it's referenced by other code that is being executed) whereas Object declarations are initialized lazily, when accessed for the first time.
Similarly, you may ask, what is the use of companion object in Kotlin?
In Kotlin, if you want to write a function or any member of the class that can be called without having the instance of the class then you can write the same as a member of a companion object inside the class. So, by declaring the companion object, you can access the members of the class by class name only.
How do you define a class in Kotlin?
To define a class in Kotlin, class keyword is used: class ClassName { // property // member function .. } Here, we defined a class named Lamp . The class has one property isOn (defined in same way as variable), and two member functions turnOn() and turnOff() .
