5. Declare an integer array named countingNumbers and fill it with the integers 1 through 10 consecutively. Do this all in one statement. (Be sure to use the same spacing as NetBeans does for this statement.)

Lab9C: 2D or not 2D For this exercise you will also be writing a program that will be building upon Lab9A. So please make new class file, copy, and rename the code you have already written for Lab9A. Please also rememb to rename the file and (and in the case of Java and C# students) class name to Lab9C. For this exercise, please take the array that was filled up with values and flatten it i.e., convert the 2-0 array to a 1-D array that contains the same values. Please do not just print the 2-D array to look li a 1-D array Hint: You will have to take the 2-D array's total amount of cells and make a 1-D array of the same siz Please refer to the sample output below for visualization and match its style. As always: Remember, the class name should be Lab9C. The user input is indicated in bold. Sample Output #1: Please enter the number of rows: 4 Please enter the number of columns: 4 I have 4 rows and 4 columns. I need to fill-up 16 spaces. The 4x4 array: 1|2|3|4| 5|6|7|8| 9|10|11|12|...

TASK 1: Write a Java program that do the following: [10 Marks] 1. Define and create an ArrayList which is called "itemsList" of Integer objects. [1 mark] 2. Define and create an array which is called "numList" with five integer vales. [1 mark] 3. Copy the five values from the array "numList" o ArrayList using a for loop. [2 marks] 4. Display the contents of the ArrayList with a message using the for loop with the get method. marks] 5. Display the size of ArrayList with a message. [1.5 mark] 6. Find the sum of ArrayList.

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 code 8. Given an existing ArrayList named friendList, find the first index of a friend named Sasha and store it in a new variable named index. 9. Given that an ArrayList of Integers named numberList has already been created and several values have already been inserted, write the statement necessary to insert the value 25 at the end of the list. 10. Declare an integer array named evens and fill it with even numbers from 2 through 10 in one statement. 11. Given an existing array named pets, find the size of the array and store it in a new variable named numPets. 12. Given an existing ArrayList named contactList, find the number of contacts in the ArrayList and store it in the existing variable named numContacts.

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...

10 Build the Sudoku Reviewer ( the testing program). The specification is below. Please note: you DO NOT have to build a Sudoku solver. To test you just need to build a class that generates a 9x9 2D array with the values you want to test. You can assume the value types are valid. (integers from 1-9). 1-The main purpose is to make sure the Sudoku solver actually solved it correctly! 2- You are also confirming the solver solves puzzle in no longer than a minute 3- Solver (not the reviewer) requires 7 INDICES (ELEMENTS) filled in the input array at least. 4- The reviewer receives both the original puzzle and the solution. The Reviewer needs to confirm the solution is not only a valid SudoKu solution but also the solution to the original puzzle. 5- Solver will return a 2d array filled with -1s if input array has an error/bad input (exception). Reviewer will check for this case.

Code with comments and output screenshot is must. Thank you!

In Java Assignment 5B : Maze Game! 2D Arrays can be used to store and represent informationabout video game levels or boards. In this exercise, you will use this knowledge tocreate an interactive game where players attempt to move through a maze. You willstart by creating a pre-defined 2D array with the following values:{"_","X","_","X","X"}{"_","X","_","X","W"}{"_","_","_","X","_"}{"X","X","_","_","_"}{"_","_","_","X","X"}You will then set the player (represented by "O") at index 0, 0 of the array, the top-leftcorner of the maze. You will use a loop to repeatedly prompt the user to enter adirection ("Left", "Right", "Up", or "Down"). Based on these directions, you will try tomove the player.• If the location is valid (represented by "_"), you will move the player there• If the location is out of bounds (e.g. index 0, -1) or the command is invalid, youwill inform the player and prompt them to enter another direction• If the location is a wall (represented by "X"), you will tell the...
