Problem2 : 2D Arrays Define a 2D array using Java code that takes from a teacher the total number of rows and the total number of columns. Then let the teacher fill the array by students IDs and courses marks for each student. And print the following: 1- Print the array. 2- Print the marks that are less than 50 (mark < 50)

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 × 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.
1. Shift Left k Cells Use Python Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]
2D arrays (matrices/grids) Write a program that takes 20 student objects and stores them in an array. Each Student object should have a first name and a last name. Sort the array by student’s last name. You can use any of the sorts you have. Then put the names into a 2D array that has 5 rows and 4 columns. Create 2 seating charts by printing the 2D array.

Problem1: 2D Arrays write a java code to Create a 3x3 2D array, fill it with numbers from the user, and check if the array is an hour glass shape or not.
2. Rotate Left k cells Use Python Consider an array named source. Write a method/function named rotateLeft( source, k) that rotates all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateLeft(source,3) After calling rotateLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]
JAVA Your teacher has created two arrays, each holding the results of tests, say Test 1 and Test 2. You need to create a new array which holds the averages of these two tests. You may assume that the first element of the first test array refers to the student who also has the grade in the first element of the second test, and the last element in each array are the grades the last student earned for each test. All students received grades for both tests, meaning both test arrays are of the same length. Complete the method, named makeAverage, in the class named Grades.java. There are two parameters to this method: the first is the integer array representing the grades of the first test, and the second is the array containing the grades of the second test. The new average array should be returned by the method. The grades should be treated as double variables. For example, consider the test grades for the five students in the following arrays: [ 87 ] [ 91 ] [ 76 ] [ 76 ] [ 94 ]…
Sales.java contains a Java program that prompts for and reads in the sales for each of 5 salespeople in a company. Now modify the program as follows: Declare an array called sales to save the sales of 5 salespeople. Complete the header of the first for loop. This loop initializes the array. Complete the header of the second for loop. This loop computes the total of array elements. Add code to compute and print the average sale. Add another loop to print the id of each salesperson and the number of their sales. The salespeople are objecting to having an id of 0—no one wants that designation. Modify your program so that the IDs run from 1-5 instead of 0-4. // *************************************************************** // Sales.java // // Reads in and stores sales for each of 5 salespeople. Displays // sales entered by salesperson id and total sales for all salespeople. // // *************************************************************** import java.util.Scanner;…
Rotate Right k cells (use python) Consider an array named source. Write a method/function named rotateRight( source, k) that rotates all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateRight(source,3) After calling rotateRight(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]
Lab Goal : The lab was designed to teach you how to use arrays to simplify solving more complex problems. Lab Description : Given a provided array, determine how many groups of a specified size exist.For the array [1,1,1,2,2,2,3,3,3,4,5,6,7] , there are 7 groups with at least one, 3 groups with at least 2, and 3 groups with at least 3. A group is a series of same values. 1 1 1 is a group of 3, but it also is a group of 1 and 2. To count as a group, all values must be the same. 1 1 1 is a group of 3 because there are 3 1s in a row.
