The interoperation which attempts to access the member of the null reference of the platform type and nullability issues with generic types and it is being used for the java interoperation. The superclass constructor calls the open type of member function whichever implemented in the derived class section and it uses the uninitialized state. Generally, the data inconsistency is regarded for to initialize and uninitialized constructor using “this” keyword and passed the values. We used “!!” operator and explicitly call and to throw the NullPointerException() in the application console. Like java language, this would be the equivalent of the NullPointerException as the cause of the kotlin language. Many languages is triage to access the member of the null reference will result in the null reference exception. The kotlin language has many types and it is aimed at eliminates the danger of the nullable variable reference. The above codes are the basic syntax for declaring and initialize the null values in the variable. Variablename = null // It shows the compilation error Var variablename: datatype = values // It is the regular initialization it accepts non-null values by default Web development, programming languages, Software testing & others fun main()
