Create an ArrayListReview class with one generic type to do the following • Creates an array list filled with the generic type of the ArrayListReview class, and inserts new elements into the specified location index-i in the list. (5 points) • Create a method inside the class to implement the calculation of Fibonacci numbers. Use System.nanoTime to find out how much time it takes to get fab(50). Create a method inside the class to check if an array list is...

Assume the Student and Employee classes each extend the Person class. The Student class overrides the getMoney method in the Person class. Consider the following code: Person p1, p2, p3; int m1, m2, m3; p1 = new Person(); m1 = p1.getMoney(); // assignment 1...
I am currently using eclipse to write in java.
A snapshot of the output would be greatly appreciated to verify
that the program is indeed working. Thanks in advance for both your
time and effort.

Deck of Cards Program I need help printing a flush, which is showing the top 5 cards of the same suite. Below is the code I already have that answers other objectives, such as dealing the cards, and finding pairs. Towards the end I have attempted printing a flush, but I cannot figure it out. public class Shuffler { /** * The number of consecutive shuffle steps to be performed in each call * to each sorting...
For this assignment, you will write a program to work with Huffman encoding. Huffman code is an optimal prefix code, which means no code is the prefix of another code. Most of the code is included. You will need to extend the code to complete three additional methods. In particular, code to actually build the Huffman tree is provided. It uses a data file containing the frequency of occurrence of characters. You will write the following three methods in the...
