write class Book which has two data fields,int pages(which represents the number of pages)and String title(which represents the title of the book).Write a constructor which uses two input parameters to initialise the data fields,and a constructor which replaces the default constructor.

Write a second class,TextBook,which extends Book,and has a data field cost of type double(which represents the cost of the book).Write a constructor which uses three input parameters to initialise pages,title and cost,but does so by using a constructor in the parent class where possible.

write above programm in java.
