Problem: Implementing a method to print a cell's neighbors on a 2D array. The method's header is provided. The main method (do not alter it)w ill read N numbers to create the 2D array and it will call the method for you. Do not go out of the bounds of the 2D array.
I have attached what it should look like with the following input:
4 4
1 2 3 4 7 8 9 10 13 14 15 16 19 20 21 22
2 2
Code I have so far:
import java.util.Arrays;
import java.util.Scanner;
public class Problem3 {
public static void printNeighbours(int[][] data, int row, int col){
}
public static void main(String[] args) {
Scanner kb = new Scanner(System.in);
int[][] data = new int[kb.nextInt()][kb.nextInt()];
for (int i = 0; i < data.length; i++) {
for (int j = 0; j < data[0].length; j++) {
data[i][j] = kb.nextInt();
}
}
System.out.println("The 2D Array:");
for (int[] cols : data) {
System.out.println(Arrays.toString(cols));
}
int row = kb.nextInt();
int col = kb.nextInt();
System.out.printf("The centre point is: %d %d (row,col)\n\n", row,col);
printNeighbours(data, row, col);
}
}

- Write a Java program to make two arrays containing random integer values (You can make these arrays with specific sizes using the below makeRandomArray method). The program should sum these two arrays and prints the resulted array (the array that contains the result of the two arrays summing). The program should also show the maximum element of the resulted array. Your program must define and call the following methods to perform the program as illustrated above: 1- A method int [] makeRandomArray(int size ,int a , int b) that makes and returns an array with specific size. The methods fills this array with random integers in a range [a..b] 2- A method public static int findmax(int x[ ]) that finds the maximum value of a number of x array passed to the method. 3- A method public static void printArray(int x[ ]) that prints the elements of the array x passed to the method. 4- A method public int[ ] sumTwoArrays(int x[ ], int y[ ]) that sums the elements of the two arrays(x and y...arrow_forwardCould i get help with this java program where you have to write a static method which reverses an integer array. The array will be a parameter to the method. Put the method in a Test class Your method would be called as follows int [] num = {2, 3, 5, 7, 11, 13, 17}; // Call the method to reverse the array Test.reverse(num); Your method should not print anything. It will be called by the following program: import java.util.Scanner; public class Main { public static void main(String [] args) { // Create a scanner object Scanner in = new Scanner(System.in); System.out.print("How many numbers: "); int len = in.nextInt(); int [] num = new int[len]; System.out.print("Enter " + len + " numbers: "); for(int i = 0; i < num.length; i++) num[i] = in.nextInt(); Test.reverse(num); System.out.print("The numbers reversed are:"); for(int i = 0; i < num.length; i++) System.out.print(" " + num[i]); System.out.println(); } } This program will read in the array and use your method to reverse the...arrow_forwardFor Java. Create a program that can read N integer numbers, store them in an array and then use a method to calculate and return the average of all numbers. Refer to photo.arrow_forward
- Needs to be written in java: Write a program with a main() method that asks the user to input an integer array of 10 elements.Next, create three methods described below. From inside your main() method, call each of thethree methods described below and print out the results of the methods 2, 3, which return values.1. printReverse() - a method that receives an array of integers, then reverses the elements ofthe array and prints out all the elements from inside the method. Print all in one lineseparated by commas (see sample output below).2. getLargest() – a method that receives an array of integers, then returns the largest integervalue in the array. (print result from main())3. computeTwice()- a method that receives the previously reversed array of integers, thenreturns an array of integers which doubles the value of each number in the array (see thesample output below). (print result from main())Sample output:Enter a number:22Enter a number:34Enter a number:21Enter a number:35Enter a...arrow_forwardNeeds to be written in java and completed using "for loops" or "nested for loops" and in one program just seperate methods: Write a program that calls these three methods. method 1 should print: 5 4 3 2 1 4 3 2 1 3 2 1 2 1 1 method 2 should print: 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1 method 3 should create and array and store 10 multiples of 5 and print it out. Use for loop to generate the multiples and then print them out using a second for loop.arrow_forwardWrite a Java method (do not write a class, only the method) with the following signature: Return type: void Parameters: 2D integer array Name: printDiagonal Implement the method code that will print out the values of the 2D array along the Diagonal from left to right. For example, if the array had the following values: 56 78 98 21 33 55 98 44 11 The method should print to the console: 56,33,11 The above 2D array example is only given for you to understand the problem Do not hard code the values in your solution or assume the array is the same as the given data. Your method should work for all 2D integer arrays.arrow_forward
- please answer question in java, thanksarrow_forwardIn JAVA Write the method below: Given a two-dimensional array containing integers, create a method called "matrixOperations" The method should do the following:1. Print out all the numbers in the array row by row (add empty line at the end of the row)2. For each row, print out the length of the row (each row is an array, remember)arrow_forward
