To do in JavaI just need an example, you can fill all classes and array list or whatever it is with basic info that can show how to do this correctly. - Trying to add a teacher, a student, or a staff member to an inexistent department (based on departmentid) should rise/throw an exception.

FOR JAVA Write a class named Matrix that has a 2 dimensional double array to hold the values of the matrix and the following methods. • Elementwise addition • Elementwise subtraction • Elementwise multiplication • Elementwise division • Dot product • Transpose • Scalar multiplication Create at least two instances of Matrix class and test all your methods, print their results. Note: These methods should not be static. The array in the Matrix class must be used in these methods. For instance, you should call your methods like this: double[][] a = {{1, 2}, {3, 4}}; double[][] b = {{10, 20}, {30, 40}}; Matrix matrix1 = new Matrix(a); Matrix matrix2 = new Matrix(b); double[][] dotProductResult = matrix1.dotProduct(matrix2); double[][] transposeResult = matrix1.transpose();
advanced java For this assignment you will write a program to represent geometric shapes and some operations that can be performed on them. The idea here is that shapes in higher dimensions inherit data from lower dimensional shapes. For example a cube is a three dimensional square. A sphere is a three dimensional circle and a glome is a four dimensional circle. A cylinder is another kind of three dimensional circle. The circle, sphere, cylinder, and glome all share the attribute radius. The square and cube share the attribute side length. There are various ways to use inheritance to relate these shapes but please follow the inheritance described in the table below. All shapes inherit getName() from the superclass Shape. Specification: The program should have the following classes: Shape, Circle, Square, Cube, Sphere, Cylinder, and Glome and two interfaces Area and Volume (Area.java and Volume.java are given below). The volume of a glome is 0.5(π2)r4 where r is the radius. Your classes…
The language used here is in Java. Please answer the question in the screenshot. Please use the code below as a base. import java.util.*; class SortingPack { // just in case you need tis method for testing public static void main(String[] args) { // something } // implementation of insertion sort // parameters: int array unsortedArr // return: sorted int array public static int[] insertionSort(int[] unsortedArr) { // to be removed return unsortedArr; } // implementation of quick sort // parameters: int array unsortedArr // return: sorted int array public static int[] quickSort(int[] unsortedArr) { // to be removed return unsortedArr; } // implementation of merge sort // parameters: int array unsortedArr // return: sorted int array public static int[] mergeSort(int[] unsortedArr) { // to be removed return unsortedArr; } // you are welcome to add any supporting methods }
Java language, please solve the 4 parts sir, thank u alot
Create, compile, and run a recursive program. Choose one of the labs listed below and program it. More details for the lab can be found in the first PowerPoint for Chapter 9. Make sure your code is recursive. You can think of recursive code this way: If you cut and paste a recursive method into another class, it should still run without problems. In other words, you cannot have any instance variables (class-level variables) that the method depends on. Choice 1 - boolean isPalindrome (String str) that returns true if the input string is a palindrome. Choice 2 - boolean find (string fullStr, string subStr) that tests whether the string subStr is a substring of fullStr Choice 3- int numDigits (int num) to determine the number of digits in the number num Choice 4 - double intPower (double x, int n) to compute x^n, where n is a positive integer and x is a double precision variable Choice 5-void printSubstr (String str) that prints all substrings of the input string.
Please help me make a game with Java. The game should have only a class and needs to include at least 3 of the following AP topics: String Array, ArrayList, 2D Array Interfaces and/or Abstract classes Polymorphism Inheritance Searching Algorithms Sorting Algorithms Recursion You also need to include a new topic that is different than the above. Once you finish creating the game, please show me the new topic that you included and let me know what are the other 3 topics that you chose from the list above and what was challenging.

Write this program in Java using a custom method. Implementation details You will implement this program in a specific way in order to gain some experience with loops, arrays and array lists. Use an array of strings to store the 4 strings listed in the description. Use a do-while loop for your 'game engine'. This means the game starts once the user enters money. The decision to stop occurs at the bottom of the loop. The do-while loop keeps going until the user quits, or there is no money left. The pseudocode for this 'game engine' is shown below: determine the fruits to display (step 3 below) and print them determine if there are 3 or 4 of the same image display the results update the customer balance as necessary prompt to play or quit continue loop if customer wants to play and there's money for another game. Use the Random class to generate a random number between 0 and 3. This random number will be an index into the array of strings. Add the string at that index to an…
Write a C#program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate. Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string) ClassRegistration -…

IN JAVA ONLY i need a classMakeArray that prints out a 10 arrays from 10-99 it must always generate a new array of elements. reset the array to the original elements in the MakeArray class (note: cant assign the backup array to the working array, need to copy the data element by element from the ackup array to the working array) i am making a bubble sort with short circuit program that consists of an array of 10 2 digit numbers case 1- makearry (makes a new random 2 digit array each time from 10-99) case 2- bubble sort with short circuit case 3- resetarray (sets the array badk to what it was before the sort)
