Class contains fields and methods so when you inherit you will get both data fields and methods in child

Syntax, applets, loops are part of any programming language but polymorphism i.e. method overriding and method overriding is one of the basic concepts of object oriented language. And polymorphism can't be done in procedural
programming

3.Answer: constructor

Explanation:

Constructor is required to initialise the object and Arguments,headers and name of the classes are not used to initialise a object and they should be set according to the given problem statement.

4.Answer: information hiding

Information hiding is making the data members private,and you can only access that data from the member functions only ,by this we can prevent users from manipulating internal data of an object into inconsistent state.
