In Java Please Create A Program For The Following; Please Note: This program should be able accept changes to the values of constants ROWS and COLS when testing the codes. Switch2DRows Given a 2D array with ROWS rows and COLS columns of random numbers 0-9, re-order the rows such that the row with the highest row sum is switched with the first row. You can assume that 2D arrau represents a rectangular matrix (i.e. it is not ragged). Sample run:...

Hi I need help with a java program that I need to create a Airline Reservation System I already finish it but it doesnt work can someone please help me I would be delighted it doesnt show the available seats when running the program and I need it to run until someone says no for booking a seat and if they want to cancel a seat it should ask the user to cancel a seat or continue booking also it...
Java 1. Write a getCount method in the IntArrayWorker class that returns the count of the number of times a passed integer value is found in the matrix. There is already a method to test this in IntArrayWorkerTester. Just uncomment the method testGetCount() and the call to it in the main method of IntArrayWorkerTester. 2. Write a getLargest method in the IntArrayWorker class that returns the largest value in the matrix. There is already a method to test this in...
Help pls! and kindly explain how you do this as well. Thaank you Write a program to test whether a square is a 3x3 magic square. A magic square is a grid with 3 rows and 3 columns, like the figure below. A magic square has the following properties: the grid contains only the numbers 1 through 9 the sum of each row, each column, and each diagonal all add up to the same number Notes: I have provided the...
create a new Java application called "Scorer" (without the quotation marks) that declares a two-dimensional array of doubles (call it scores) with three rows and three columns and that uses methods and loops as follows. Use a method containing a nested while loop to get the nine (3 x 3) doubles from the user at the command line. Use a method containing a nested for loop to compute the average of the doubles in each row. Use a method to...
