I need help with step 1 1. Complete the private int[U] copy0fBoard (int[][] originalBoard)method. In this method, you need to declare a 2D array with the same length of theparameter array originalBoard. Then your code must copy values in the parameterarray originalBoard to the array you just created and then return it.2. Complete the private int[] getTwORanNum(int min, int range) method.In this method, you should generate two random numbers in the range min ~ (min +range) and put them into a single dimensional array. Then your code must return thisarray. For example, if the passed value of min is 5, the passed value of range is 10, then yourcode need to generate two random numbers in the range 5 ~ 14. 2 HW.jaimport java.util.Arrays;import java.util.Random;PAPEpublic class Sudoku {public static final int[J BOARD = {(4, 3, 5, 8, 7, 6, 1, 2, 9},{8, 7, 6, 2, 1, 9, 3, 4, 5},{2, 1, 9, 4, 3, 5, 7, 8, 6},(5, 2, 3, 6, 4, 7, 8, 9, 1},{9, 8, 1, 5, 2, 3, 4, 6, 7},{6, 4, 7, 9, 8, 1, 2, 5, 3},{7, 5, 4, 1, 6, 8, 9, 3, 2},{3, 9, 2, 7, 5, 4, 6, 1, 8},{1, 6, 8, 3, 9, 2, 5, 7, 4}};222324252627public static final int GRID_SIZE = 9;public static final int SUBGRID_SIZE - 3;public static final double EMPTYCELL PERCENTAGE = 0.5;public static final 5tring VALUE= "123456789":28293031private int[) puzzle;private Random random - new Random();32333435V/ Create a copy of Lhe sudoku boardprivate int[) copyofBoard(int[][] originalBoard) {// step 1V/ copy a the passed 20 array to a new array and then return it36373839404142/7 provide twd rändom number as an array With length tw./ used to hide ome numbersprivate int[) getTwokan Num (int min, Int range)43449/ strp 277 generate tuo runcom integers in the range min-mintrangesaveLrmina LD array and return it4546474849/ Hide nome numbers to create puzzle.public int[l createNewPuzzle(int]U board) {this puzzle = cupyofBoard(board);int numofEmptylell = (int) Nath.floor(EMPTYCELL_PERCENTAGE * GRID_STZE * GRID S:5051-525354|WritableP Type here to searchesc%233.Wtabps lock

1. Complete the private int[U0 copy0fBoard(int[][] originalBoard) method. In this method, you need to declare a 2D array with the same length of the parameter array originalBoard. Then your code must copy values in the parameter array originalBoard to the array you just created and then return it. 2. Complete the private int[] getTwORanNum(int min, int range) method. In this method, you should generate two random numbers in the range min ~(min range) and put them into a single dimensional array. Then your code must return this array. For example, if the passed value of min is §, the passed value of range is 100, then your code need to generate two random numbers in the range 5 ~ 14.

Write a method with header static void DisplayIntArray(int[] numbers). The first argument is an array of ints. There is no return value. This method displays all the elements of the argument on a single line. Each item will occupy three columns.Call this method from main with a suitable argument. Write a method with header static int[] GenerateRandomIntArray(int numberOfItems, int largestValue). The first argument is an int indicating the number of elements that will be present in the return array. The second argument is an int representing the largest item in the array. The returned value is an array of integers. This method does the following: Declare and initialized a variable of type Random (Random generator = new Random();) Declare an array of type int (you may call it result) Allocate storage for the correct number of items Using your favorite looping statement, assign a random integer to each element of the array (result[i] = generator.Next(largestValue);) In your…
Image one is my file or you can create ur own file as long as it's similar to mine. image 2 is my program I want to write a 4th method(method 4) and the spec is: A method to count the occurrences of each value in an array takes one parameter, an array of integers returns an array containing the number of times each value occurs in the parameter array. Also should call method 3 from method 4Hint: The general idea of this method is using an array with length maxVal+1(maxVal should get from method 3 already) to save the occurrences of each number. For example, if number 44 occurs 3 times in the file, your array should have a value 3 stored at index 44.
please help me with this JAVA Programming challenge from chapter 7. Below is the challenge question Thank you 17. 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…

Problem: Write a method that will determine whether a given value can be made given an array of coin values. For example, each value in the array represents a coin with that value. An array with [1, 2, 3] represents 3 coins with the values, 1, 2, and 3. Determine whether or not these values can be used to make a desired value. The coins in the array are infinite and can only be used as many times as needed. Return true if the value can be made and false otherwise. Dynamic Programming would be handy for this problem. Data: An array containing 0 or more coin values and an amount. Output: Return true or false. Sample Data ( 1, 2, 3, 12, 5 ), 3 ( 4, 15, 16, 17, 1 ), 21 ( 1 ), 5 ( 3 ), 7 Sample Output true true true false
Create 2D array 4 *5. Ask the user to enter the number inside the array. Print the numbers organized by rows. Calculate the average for each row. Print the least average. Finally, create a method that receives a 2D array to print its elements reverse starting from the last element.
3. write a method called insert that inserts an element into an integer array. It should take 3 parameters: an int array, the number to be inserted and the index it should be inserted at. It should return a new array that has the element inserted at the index (the new array should have a length 1 longer than the original array). Sample code int[] a = {1,2,3,4,5}; int[] inserted = insert (a,9,0); printArray (inserted); int [] a = {1,2,3,4,5}; int[] inserted = insert (a,9,3); printArray(inserted); int [] a = {1,2,3,4,5}; int[] inserted = insert(a,9,5); | printArray(inserted); Sample output 912345 123945 123459
Define an array to be a 121 array if all elements are either 1 or 2 and it begins with one or more 1s followed by a one or more 2s and then ends with the same number of 1s that it begins with. Write a method named is121Array that returns 1 if its array argument is a 121 array, otherwise, it returns 0. There is one additional requirement. You should return 0 as soon as it is known that the array is not a 121 array; continuing to analyze the array would be a waste of CPU cycles. If you are programming in Java or C#, the function signature isint is121Array(int[ ] a) If you are programming in C or C++, the function signature isint is121Array(int a[ ], int len) where len is the number of elements in the array a. Examples a is then function returns reason {1, 2, 1} 1 because the same number of 1s are at the beginning and end of the array and there is at least one 2 in between them. {1, 1, 2, 2, 2, 1, 1} 1 because the same number of 1s are at the beginning and end of…
