Instructions for Part 2In part 2 (and probably in every part) I'm going to use "matrix" and "two-dimensional array"interchangeably.In part 2 we will read in the data from file, prepare ThreadOperation for part 3 by adding inputs,and add another helper method to verify we can access the submatrices accurately.1. Modify ThreadOperation to take as input (through the constructor) two matrices and aquadrant indicator. The indicator could be a String, an int, an enum or a set of indexes. It's upto you.2. Modify the main method to instantiate the four ThreadOperation objects withplaceholder values to confirm that the code still runs without error. The placeholders are justexample matrices and a quadrant indicator.3.Write a static method named printSubmatrix that takes four integer indexes and amatrix and prints out the submatrix indicated by the indexes.4.Create a matrix and use it to test printSubmatrix in main. Your print2dArraymethod from part 1 should come in handy for this.5.The filename should be given through the command prompt and passed into main viaString[] args6. Open and connect to the file using a Scanner.7. Read in the number of rows and columns and save these in local variables in main.8. Read in the first and second matrices (two-dimensional arrays) from the file. I recommendwriting a method to accomplish this task and calling the method twice (once for each matrix).Consider using this method header:

the program is an given below :

You are required to demonstrate competency in any or all of 2D arrays, doubly linked lists, merging of sorted data structures and constructive and destructive programming techniques. Code your solution according to the requirements below. And add comments: Class Tester, method process: Modify the following(in particular method process in class Tester).
Design and implement a service that simulates PHP loops. Each of the three loop variants should be encapsulated in an object. The service can be controlled via a parameter and execute three different simulations. The result is returned as JSON. The input is an array consisting of the letters $characters = [A-Z]. -The For loop should store all even letters in an array.-The Foreach loop simulation is to create a backward sorted array by For loop, i.e. [Z-A] .-The While loop should write all characters into an array until the desired character is found. Interface:-GET Parameter String: loopType ( possible values: REVERSE, EVEN, UNTIL )-GET parameter String: until (up to which character) Output:JSON Object: {loopName: <string>, result: <array> }
Part I Explain encapsulation and packaging in Java. Part II Create a package for int array operations. Provide at least 5 different operation by this package. The operations are totally up to you. Part III Create a Test package in order to test the operations you defined in Part II. Note: Do not compress your files, submit only java files. Note: Do not forget to justify your answers with comments.
Need help making a java file that combines both linearSearch and binarySearch •Both search methods must use the Comparable<T> interface and the compareTo() method.•Your program must be able to handle different data types, i.e., use generics.•For binarySearch, if you decide to use a midpoint computation formula that is different fromthe textbook, explain that formula briefly as a comment within your code. //code from textbook //linearSearch public static <T> boolean linearSearch(T[] data, int min, int max, T target) { int index = min; boolean found = false; while (!found && index <= max) { found = data [index].equals(target); index++; } return found; } //binarySearch public static <T extends Comparable<T>> boolean binarySearch(T[] data, int min, int max, T target) { boolean found = false; int midpoint = (min + max)/2; if (data[midpoint].compareTo(target)==0)…
It says that 'readmatrix' is undefined. Do I need to use dlmread()? My original question was more if I had a file with entries, how do I throw them into a matrix?
Design and implement an insertSorted() method for the MyArrayList class. The method should receive a single object and insert it in its correct position. You can assume that the calling array is already in a sorted order. The calling array is therefore updated. Follow the three step method for designing the method. Develop the java code for the method. Create a test program to test the method thoroughly using the Integer wrapper class.
Use the ArrayList class Add and remove objects from an ArrayList Protect from index errors when removing Practice with input loop Details: This homework is for you to get practice adding and removing objects from an ArrayList. The Voter class was used to create instances of Voters which held their name and a voter identification number as instance variables, and the number of instances created as a static variable. This was the class diagram: The constructor takes a string, passed to the parameter n, which is the name of the voter and which should be assigned to the name instance variable. Every time a new voter is created, the static variable nVoters should be incremented. Also, every time a new voter is created, a new voterID should be constructed by concatenating the string “HI” with the value of nVoters and the length of the name. For example, if the second voter is named “Clark Kent”, then the voterID should be “HI210” because 2 is the value of nVoters and 10 is the number…
Please keep the simulation neat and well organized. It is a request. NOTE: I AM ASKING FOR SIMULATION, NOT THE CODE. SO DON'T WRITE THE CODE. Perform QuickSort on the given array. You need to show the whole simulation. A = [10,3,9,18,21,26,30,8,15,6,17].
Java (Sort, IComparable) The librarian wants to sort the media in the ArrayList by title. For this purpose, the Medium class should implement the Comparable interface. Implement a Method compareTo (...) in the abstract class Medium. Then sort the Media in the ArrayList. Implement the sort method in the Zettelkasten class.This should, by Parameters can be selected, the media contained in descending ("A" → "Z") or ascending ("Z" → Sort "A") by title. Please do not implement your own sorting algorithm, but rather simply use a suitable method of the ArrayList class. Increase the efficiency of the note box. The note box should remember whether the The media contained therein are already sorted, e.g. by calling sort earlier. In this case, re-sorting should be omitted.
Use the right loop for the right assignment, using all the follow- ing loops: for, while without hasNext(), while with hasNext() and do-while. So I cannot use array. it has to be done in java.
please use the name, phonenumber and phonebookentry to build this. The three parallel arrays are gone — replaced with a single array of type PhonebookEntry. You should be reading in the entries using the read method of your PhonebookEntry class (which in turn uses the read methods of the Name and PhoneNumber classes). Use the equals methods of the Name and PhoneNumber classes in your lookup and reverseLookup methods. Use the toString methods to print out information. Make 100 the capacity of your Phonebook array Throw an exception (of class Exception) if the capacity of the Phonebook array is exceeded. Place a try/catch around your entire main and catch both FileNotFoundExceptions and Exceptions (remember, the order of appearance of the exception types in the catch blocks can make a difference). Do not use BufferedReader while(true) breaks The name of your application class should be Phonebook. Also, you should submit ALL your classes (i.e., Name, Strip off public from all your class…
