Design, implement and test an object-oriented Java program for processing single-variable polynomials represented as lists. Consider polynomials with integer coefficients and positive integer exponents. Implement the operations of addition and subtraction of two polynomials.Read the polynomials from an input file. A polynomial is represented in the input file by its name, the equal sign, and a set of pairs of integers, each pair consisting of the exponent and its corresponding coefficient. For example, `P1 = 3 5 1 -4 0 8` represents the polynomial (in human readable form) `5X^3 -4X + 8`. After reading all polynomials, they will be displayed on the console in human readable form. A polynomial will always be written from the highest exponent to the lowest. A term having coefficient value zero will be omitted.The operations on polynomials will be entered by the user from the console. The user will be required to enter the two polynomial operands and the operator.
After executing the required operation:
(i) the program should store the new generated polynomial (to be further used in other operations),
(ii) the result will be shown at the console in human readable form and (iii) the user will be allowed to specify another operation or to exit the program.
Study the concept of inheritance and the object hierarchy in object-oriented programming, and write a paper comparing these concepts with the concept of inheritence.
Design a program that determines how many males and females live in each of the Zip Code areas in the Student Enrollment Records Set.
You wish to create a program which will keep track of the game collection at home. The program must recognize the platform.
Add operation queueCount to class queueType (the array implementation of queues), to return number of elements in the queue. Write down the definition of function template.
Write a program which will prompt user to enter ahex digit character ("0" ..."9" or "A" .."F") ,display it on next line in decimal, and ask user if he or she wants to do it again.
Continue in this fashion until entire array is read. Then recursively determine a candidate for B; this is candidate for A (why?). How does the recursion terminate?
Write down the class definition of subclass of Square called FancySquare which has a method called getDiagonal. The getDiagonal method gets no arguments.

Checks to see if the value of a is 0; if it is, the code prints the message "no solution for a=0" and returns from the function.
Write a program that accepts six(6) pairs of values from the user and then calculates and stores the difference of each pair of values in an array.
Create and execute the class called Book which contains instance data for title, author, publisher, and copyright date. Explain the Book constructor to accept and initialize this data.
Write a program that generates all the factors of a number entered by the user. For instance, the number 12 has the factors 2 * 2 * 3.
