1. You are given Stack.java, an interface class for Stacks. /* Use an array to implement the Stack.java in a class called ArrayStack.java that uses Generics. Write a main function that creates two stacks, one containing 10 Integers and a different one containing 10 Strings, and reverses there contents using a method called reverse that takes as a paramater a Generic array. You will need to implement all the methods of Stack.java as well as create a toString method in...

Which of the following situations described is a good situation to use an abstract class, and where it would be better to use than either a concrete class or an interface? When some methods in the class are abstract and some are concrete, and some variables in the class need to be private, while other variables need to be public When the inheriting class is closely related to the abstract class, such as with an "is-a" relationship When the objects...

Exercise #1: Create an abstract class called GameTester. The GameTester class includes a name for the game tester and a boolean value representing the status (full-time, part-time). Include an abstract method to determine the salary, with full-time game testers getting a base salary of $3000 and part-time game testers getting $20 per hour. Create two subclasses called FullTimeGameTester, PartTimeGameTester. Create a console application that demonstrates how to create objects of both subclasses. Allow the user to choose game tester type...

Create an Interface DiscountPolicy. It should have a single abstract method computeDiscount that will return the discount for the purchase of a given number of a single item. The method has two parameters, count (int type) and itemCost (double type). Create a class BulkDiscount that implements Interface DiscountPolicy. The BulkDiscount class has two proprieties: theMinimum (int type), and percent (double type). It should have a constructor that sets the parameters, minimum and percent to a given values. It should define...
