1. Create a new Java project named ExerciseArray2. 2. Create a class named Matrix that has the following methods: Create that will allow user to specify an nxn two-dimensional array and also allows the user to enter the values in both arrays.. You can also hard code the arrays. • Sum that accepts two two-dimensional arrays (matrices) as arguments and returns a two-dimensional array representing their sum. • Product that accepts two two-dimensional arrays (matrices) as arguments and returns a two-dimensional array representing their product. • Display that accepts a two-dimensional array as an argument and displays its elements. 3. Create a class MatrixTest to invoke the previous methods with the following two matrices: (1 2 3 M1-3 0 1 and M2-8 2 1 4 (5 -10 6) 7 -1 3 2 Note that (6 -8 9) M1+M 2-11 7 13 10 and M1×M2-15 - 27 20 21

In this project you will generate a poker hand containing five cards randomly selected from a deck of cards. The names of the cards are stored in a text string will be converted into an array. The array will be randomly sorted to "shuffle" the deck. Each time the user clicks a Deal button, the last five cards of the array will be removed, reducing the size of the deck size. When the size of the deck drops to zero, a new randomly sorted deck will be generated. A preview of the completed project with a randomly generated hand is shown in Figure 7-50.
JAVA PROGRAM Homework #1. Chapter 7. PC# 2. Payroll Class (page 488-489) Write a Payroll class that uses the following arrays as fields: * employeeId. An array of seven integers to hold employee identification numbers. The array should be initialized with the following numbers: 5658845 4520125 7895122 8777541 8451277 1302850 7580489 * hours. An array of seven integers to hold the number of hours worked by each employee * payRate. An array of seven doubles to hold each employee’s hourly pay rate * wages. An array of seven doubles to hold each employee’s gross wages The class should relate the data in each array through the subscripts. For example, the number in element 0 of the hours array should be the number of hours worked by the employee whose identification number is stored in element 0 of the employeeId array. That same employee’s pay rate should be stored in element 0 of the payRate array. The class should have a method that accepts an employee’s identification…
JAVA PROGRAM Lab #2. Chapter 7. PC #11. Array Operations (Page 491) Write a program that accepts a file name from command line, then initializes an array with test data using that text file as an input. The file should contain floating point numbers (use double data type). The program should also have the following methods: * getTotal. This method should accept a one-dimensional array as its argument and return the total of the values in the array. * getAverage. This method should accept a one-dimensional array as its argument and return the average of the values in the array. * getHighest. This method should accept a one-dimensional array as its argument and return the highest value in the array. * getLowest. This method should accept a one-dimensional array as its argument and return the lowest value in the array. This part of the program is not correct. There should be no Scanner. You should read the file name from the command line.Scanner scanner = new…
