    Due: Friday 11th Question 1Write a (non-static) method getSize() in class BST that computes the number of nodes in a BST.Hint:• Do NOT modify the code to count the nodes when you do put().• The code for this method should be a few lines at most (if it isn&quot;t, then you are approaching the problem incorrectly) – if written concisely this method will be one line long :-)• The power of recursion ...Question 2Write a (non-static) method getDepth() in class BST that computes the depth of a BST.Hint:• The code for this method should be a few lines at most (if it isn&quot;t, then you are approaching the problem incorrectly) – if written concisely this method will be one line long :-)• The power of recursion ...Question 3Write a static method random(int N) in class BST that returns a random BST of size N.Hint:• The values are irrelevant to the tree structure (it depends only on the keys), so you just have togenerate random keys and insert them into an initially empty BST.• The type of the keys is also irrelevant to the tree structure (it depends only on the probabilitydistribution of the keys), so you can just use Integer or Double for your keys.Question 4Write a program that estimates the average depth of a BST of N nodes as a function of N.For various choices of N, generate M random BSTs of size N (for some fixed M) and compute the average of their depths.Plot N against the average depth for N (so N on the x-axis, average depth on the y-axis)Try and guess what function of N you have by plotting various other functions on the same axis.Hint:• M is fixed (i.e. does not depend on N), so generate the same number of random trees for each N.• The larger M is the more accurate your average will be.• Getting an accurate average will probably require M > 1000 (maybe even higher), so make sure you write your program so that you can change M easily and re-run it..

    (Throwing and declaring exceptions)This assignment will be where you learn about catching exceptions.You may also have to write code samples to illustrate your answers.Question 1Discuss the difference between Error and Exception.Discuss the difference between Exception classes that are sub-classes of RuntimeException and those that are not. Question 2Consider the following;;publicclassMain {publicstaticvoiddoSomething()throwsException {//some code that throws an Exception}publicstaticvoidmain(String[] args) {try{doSomething();}catch(FileNotFoundException ex) {//}catch(IOException ex) {//}catch(Exception ex) {//}finally{//}}}Explain how exception catching works – pay particular attention to the sub-class relationship that existsbetween the various exception classes.Make sure your explanation covers what happens if doSomething throws:-a FileNotFoundException.-an IOException (note that FileNotFoundException is a sub-class of IOException).-some other kind of exception.Also make sure you explain when the finally clause is run.Question 3What happens in the previous example if one of the catch blocks throws an exception?Question 4What happens in the previous example if the finally block throws an exception?Question 5Give an example of the a try-with-resources statement.Discuss what they are used for, and what code you would have to write if you didn&quot;t have them in Java(they were introduced in Java 1.7 I think).

    Question 1Do an execution tree as I did in class for merge sort for the following array of numbers: 15 12 16 13 1114 10 17 2.As I did in class clearly indicate the order in which the merge sort and merge steps are done, and theresult of each step. &quot;دي موجودة عندي حعملها سهلة&quot;Note: Be careful to get the sizes of the first and second half arrays correct (check the text code formerge sort for details!).Question 2In this question you will measure the performance of merge sort by plotting N against the number ofcomparisons and copies needed to sort a randomly generated array of N doubles.Write methods that:• checks whether an array is sorted (re-use your code from assignment 4).• generates a random array of doubles of size N from a random source R (re-use your code fromassignment 4).• takes two sorted array, A and B, and returns the merge of them (use the code in text if youwant).• sorts an array of doubles, A, using merge sort (use the code in the text if you want).Instrument your sorting routine to count the number of compares and copies done to merge sort anarray of size N.Write a main routine which, for various appropriate choices of N generates a random array of size N,calls merge sort on that array, checks that the array is sorted, and outputs the number of compares andcopies per N.You should be able to sort for much larger values of N than in assignment 4.Do a plot (in Excel, OpenOffice, etc) of N against the number of compares and copies, labeling the axisnicely, etc. Also plot N log(N), 2N log(N), and 4N log(N), all on the same axis.اسايمنت 4 هو اخر واحد بتاع السورتنقان شاءالله حجيب الكود تبع الemergeعشان تاخد فكرة

    Question 1Write a class that reads a file and outputs a list of the unique words in the file and the number of times each unique word occurs.Run it on the file provided with the assignment.Question 2Modify your program from Question 1 to print the list of words and their counts out to another file.For those who wanted to see the file reading code I wrote in class, here it is:public static void main(String[] args) throws FileNotFoundException, IOException {File f = new File(&quot;/Users/graham/Desktop/fred.txt&quot;);FileReader reader = new FileReader(f);BufferedReader breader = new BufferedReader(reader);String s = breader.readLine();System.err.println(s);System.err.println(breader.readLine());System.err.println(breader.readLine());System.err.println(breader.readLine());System.err.println(breader.readLine());}NOTE: Several people have asked me about blank lines in the input file.They are meant to be there -- your code should takes steps to deal with them correctly.

Write code for the while loop that Java translates the for loop into.Question 2Trace the execution of the while loop from Question 1.Draw a picture showing objects as boxes with fields being either values or references to other objects (i.e. boxes), like I have be doing in class for:• the list l.• the initial iterator object.Show the sequence of hasNext and next calls that occur, and how the iterator object changes with each call.Question 3Write an iterator for the MyLinkedList class, just like we did for MyArrayList.As per Question 1, write code showing your iterator running on an instance of your MyLinkedList class.Question 4As per question 2 trace the execution of your iterator for the MyLinkedList class for the followingcode:MyLinkedList l = new MyLinkedList();l.add(3);l.add(5);l.add(7);l.add(9);l.add(11);for(Integer x : l){ System.out.println(x);}عندي البروجكت يلي كتبهم الدكتور بالصف راح أرسلهم لك عالايميل لو حابب وبرضه فكرة رسمة البوكسس

    This will be done in the form of a library system that allows users to borrow various items that the library holds. You will be required to create a inheritance structure to contain all the different types of items the library might hold. In this case there are five different types of items Books, Magazines, Blurays, DVDs and MusicCDs. You are required to create a library class that manages this system allowing an item to added or removed from the system in addition to allowing a person to borrow an item and return it. In this program I will supply you with an incomplete testing program. You will be required to generate the rest of the classes in your program.
