Write a program that creates a Date object, sets its elapsed time to 10000, 100000, 1000000, 10000000, 100000000, 1000000000, 10000000000, and 100000000000, and displays the date and time using the toString () method, respectively.
The Delicious class – iterative methods The Delicious class must:• Define a method called setDetails which has the following header: public void setDetails(String name, int price, boolean available) This must find in the ArrayList the Chicken with the given name, change itspricePerKilo to the given price parameter and set whether it is in stock or not. A value of true for the available parameter means the chicken is in stock and a value of false means it is sold out (not in stock). Note that there will only be at most one Chicken object of the given name stored in the ArrayList.• Define a method called removeChicken that takes a single String parameter representing a chicken’s name. This method must remove from the ArrayList the Chicken object (if any) with the given name. The method must return true if a cheese with the given name was found and removed, and false otherwise.The Delicious class – challenge method In the Delicious class complete the findClosestAvailable method: This…
Write an application (including algorithm) that uses a class called “Book” (seedetails below). The application must perform the following tasks. Create an array of “Book” objects (i.e., array must be able to store 2books). Create 2 “Book” objects initialized as follows.o title = “C++ Textbook”; Author = “Pete Parker”; Publisher =“Cengage”, ISBN = “0123456789”; subject = “Computer Programming”;o title = “Java Textbook”; Author = “Bruce Wayne”; Publisher = “McGrawHill”, ISBN = “9876543210”; subject = “Computer Programming”; Add the two books to the array.o Assume the two publishers have merged into a new company called“BookConglomerate”. Use a loop to create statements to modify thepublisher field with the new publisher name. Display the following information for both bookso Book Title (i.e., “C++ Textbook” or “Java Textbook”)o Authoro Publishero ISBNo SubjectThe Book class must contain the following. Constructor with parameters that initialize all instance variables title, author,…

• RectangleTest class: o Perform the following actions in the main method: • Create an object named r1 of the Rectangle class using the default constructor. • Using the set methods, initialize rl to have width 3.0 and length 5.2. • Use the printDimensions method to output all the data (width & length) related to r1. • Create another object named r2 of the Rectangle class with width 2.6 and length 5.4 using the overloaded constructor. • Print out r2 (width & length) using the get methods. • Print out the area and the perimeter of r1 using the calculateArea and calculatePerimeter methods. • Print out the area and the perimeter of r2 using the calculateArea and calculatePerimeter methods.
forceAppliedValue and contactAreaValue are read from input. Declare and assign pointer myBallObject with a new BallObject object. Then, set myBallObject's forceApplied and contactArea to forceAppliedValue and contactAreaValue, respectively.
