Question

A class can have multiple constructors and each constructor must accept a unique set of parameters. True False

Answer 1

1) A Class can have multiple constructors and each constructor must accept a unique set of parameters

TRUE

because when we compile dynamically it gives us a error called ambiguity error but on error doesnot occur when we compile in static.so, a class can have multiple constructors and each constructor must accept a unique set of parameters.

2) if a sub class has more than 2 constructors that requires parameters,then the sub class can inherit these constructors automatically and we do not need to write any constructors in the sub class

FALSE

because constructors cannot be inherited through subclass for that we need to create specified objects .so a sub class cannot inherit the constructors automatically.

3) An inner class can reference the data and methods defined in the outer class in which it nests,so you do not need to pass the reference of the outer class to the constructor of the inner class

TRUE

because if we created a nested class we can acces the constructor methods of outer class by using call by reference form the inner class .so in this there is no need to pass the reference of the outer class to the constructof the inner class
