### Java Program DescriptionThe Java program `ArrayTest.java` is designed to perform the following tasks:- **Fill an Array**: Populate the array with integer values obtained from the file `ints.txt`. - **Shift Elements**: Execute a right shift of the elements in the array `a` by one position. The last element of `a` is moved to the first position, creating a wrap-around effect.#### ExampleIf the array `a` originally contains `{1, 2, 3, 4}`, after the operation, the resulting array `a` would be `{4, 1, 2, 3}`.### Command Line InputTo redirect the input to the program `ArrayTest` so it uses the data from the text file `ints.txt`, what command would you use on the command line?**Enter your answer here:** [Text box for answer input]

The purpose is to write a program with 2D arrays that will display Knight's Tour. Knight's Tour is a fascinating problem that is done on an electronic chessboard with a knight. Starting at any location on the chessboard, a knight proceeds to move on the board in such a manner that all positions on the chessboard are visited, once and once only. The knight may only move according to the rules of chess playing. The matrixes below show a sequence of knight moves that starts from the top-left corner. In most cases, the knight is locked in place and can go no farther. Note: there are only 3 legal knight moves from the 44 locations and they have already been visited. 01 60 39 34 31 18 09 6438 35 32 61 10 63 30 1759 02 37 40 33 28 19 0836 49 42 27 62 11 16 2943 58 03 50 41 24 07 2048 51 46 55 26 21 12 1557 44 53 04 23 14 25 0652 47 56 45 54 05 22 13 01 22 39 20 03 18 09 1600 37 02 23 08 15 04 1335 40 21 38 19 12 17 1000 00 36 41 24 07 14 0500 34 00 32 00 28 11 2600 00 00 00 42 25 06 2900…
2. Write a program that will load A with 15 random numbers (range : 1-50). Display elements of A in ascending order. Then get a number X. Compare X to each element of A, if array element is less than X, replace that element with X. On another line, display elements of A after replacing all elements less than X with X.
Use a one-dimensional array to solve the following problem: Read in 10 numbers, each of which is between 10 and 100. As each number is read, print it only if it's not a duplicate of a number that has already been read. Provide for the "worst case", in which all 10 numbers are different. Use the smallest possible array to solve this problem. This needs to be in Java and Html.

Write a Java program to do the following: • Create a two-dimensional array named "marks" and size n-by-5 (n X 5). This array represents students' marks in ITCS114 course. Where we have n students registered in this course and each student has 5 assignments. The number of students(n) should be entered by the user. Prompt the user to enter the values of the array. • Make a copy of array "marks" with reverse rows order into another array and name it "rMarks". Where the first row of array "marks" should be copied in the last row of array "rMarks" and so on for all rows. • In the array "marks", add extra one mark in the 3rd assessment for all students who have scored 4.0 or more in this assessment. • Print the values of the "marks" and "rMarks" arrays. For example, if n=4 and "marks" array as follow: 4.5 4.5 1.5 5.0 3.5
this is insturction Write a program which prompts the user to enter up to 15 floating point numbers (terminated with a non-numeric), reads them into an array, then prints the following. The program must use an array (not a vector) to get credit. The array values in the original order, separated by commas, with no trailing comma at the last value. The array values where the order of each adjacent pair of elements is swapped, separated by commas (NOT every element swapped with its next neighbor, which would just move the first element to the end, but every original pair swapped only in that pair. For an odd element count, the last element should not change. See examples below.) The smallest number in the array. Example program outputs with user input shown in bold font: Enter up to 15 numbers, and a non-numeric to quit: 1 0 -1.001 # Original array: 1, 0, -1.001 The swapped array: 0, 1, -1.001 Smallest number: -1.001 Enter up to 15 numbers, and a non-numeric to quit: 1 0 -1.001 5 ,…
In java Define and create a 2-dimensional array of integers with 4 rows and 8 columns. Print the elements of the array in table format (rows and columns). Replace the element in the second row and third column of the array with the value 99.
