Create a class Hugeinteger which uses 40-element array of digits to store integers as large as 40 digits each.Provide methods inputHugeInteger, outputHugeInteger, addHugeIntegers, and subtractHugeIntegers. For comparing HugeInteger objects, provide methods isEqualTo, isNotEqualTo, isGreaterThan, isLessThan, isGreaterThanOrEqualTo , and isLessThanOrEqualTo-each of these is a "predicate" method that simply returns true if the relationship holds beteen two HugeIntegers and returns false if the relationship does not hold. Provide a predicate method isZero. If you feel ambitious, also provide the method multiplyHugeIntegers, the method divideHugeIntegers and the method moduleHugeIntegers.

Create an application program that consists of 2 classes ,a "startup class" and a second class that prints out the values of atleast 3  instance varibles that are initialized in one method and printed from another .The initialization method should have two forms.One of them will have no arguments and other 3 arguments corresponding to the data types of the 3 instance variables. The second class should also contain a "class vriable" of one of the 8 primitive data types (you choos). Create 2 instances of the second class. Using one instances, set the class variable to some value and, using the second instance, print that value out. Also using either or both of the 2 instances, call the methods that set and print the 3 instance variables.

Create an application that is composed of at least 2 classes in addition to the startup class.One of the classes is to be a subclass derived from the other. The subclass is to have at least 3 constractors which will be called during the creation of 3 subclass objects.In the example shown, the subclass student has a default constractor, a constractor with one string argument, and a constractor with a string argument
giving the student's name and integer argument giving an ID number.

Write an inheritance hierarchy for classes Quadrilateral, Trapezoidal, Parallogram, Rectangle and Square.Use Quadrilateral as the superclass of the hierarchy. Make the hierarchy as deep (i.e., as many levels) as possible.The private data of Quadrilateral should include the (x,y) co-ordinate pairs for the four end points of the Quadrilateral. Write a driver program that instantiates and displays object of each of these classes.
