JAVA PROGRAM Chapter 7. PC #16. 2D Array Operations Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods: • getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. • getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. • getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the total of the values in the specified column. • getHighestInRow. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the highest value in the specified row of the array. • getLowestInRow. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the lowest value in the specified row of the array. Demonstrate each of the methods in this program.

In visual basic Print out the last value in a single-dimensional array.

When an array is passed as a parameter to a method, modifying the elements of the array from inside the function will result in a change to those array elements as seen after the method call is complete. O True O False

FYI: Please write the code in Pseudocode (no programming language please) 1. Write pseudocode to load a single array with data. Then search that array for a match. Here are the specifics. You do NOT have to write the entire program. Load the array with data from a file named customerNumbers Ask the user to enter their customer number Search the array for the customer number If you find a match output FOUND If there is no match output NOT FOUND

10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated...

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9

JAVA PROGRAM: Monkey Business A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 ×ばつ 5 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey, or use constant values rather than asking user for input. Then it should create a report that includes the following information: Display 3X5 array first. Average amount of food eaten per day by the whole family of The least amount of food eaten during the week by any one The greatest amount of food eaten during the week by any one Input Validation: Do not accept negative numbers for pounds of food eaten.

Lab Activity for the students: Exercise 5: Write a program that asks the user to input 8 numbers and save them in a 2D array with 4 rows and 2 columns. The program finds the sum of all elements and prints the array in reverse order. (1 Mark ) Example : If the inputs are 12, 7, 23, 86, 40, 64, 97, 55. Then, the program will print: 55 97 64 40 86 23 7 12 Sum = 384
