- Write the method sum2D() which accepts a two dimensional integer array and returns the sum of all the elements of the array.Write method to reverse sequence of elements in array. if you call a method with array: 1 4 9 16 9 7 4 9 11 array is converted to. this is just example 11 9 4 7 9 16 9 4 1write a method that receives an array and sorts it in an increasing order
- Write a method that returns the sum of all the elementsin a specified row in a matrix using the following header:public static double sumRow(double[][] m, int rowIndex)PointComplete the findMax() method that returns the largest value in array nums. Ex: If array nums contains: 2 4 6 8 10 7 5 3 the findMax() method returns: 10 Note: During development, array nums is filled with 10 pseudo-random integers in main() using the fillRandomly() method with a seed value of 7. When submitted, different seed values will be used to generate arrays of different size for the test cases. Refer to the textbook section on Random numbers to learn more about pseudo-random numbers. Code: import java.util.*;public class Numbers { private int[] nums; public int findMax() { /* Type your code here. */ } public void setNums(int[] nums) { this.nums = nums; } public int[] getNums() { return nums; } // Fill array nums with pseudo-random integers (0-999) with a seed value public void fillRandomly(int seed, int size) { Random rand = new Random(seed); nums = new int[size]; for(int i=0; i<nums.length; i++) { nums[i]…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.
- Implement the following method to sort the columns in a twodimensional array. A new array is returned and the original array is intact.public static double[ ][ ] sortColumns(double[ ][ ] m) Write a test program that prompts the user to enter a 4 X 4 matrix of doublevalues and displays a new column-sorted matrix. Here is a sample run: Enter a 4−by−4 matrix row by row:0.15 0.875 0.375 0.225 ↵Enter0.55 0.005 0.225 0.015↵Enter0.30 0.12 0.4 0.008 ↵Enter0.07 0.021 0.14 0.2 ↵EnterThe column−sorted array is0.07 0.005 0.14 0.0080.15 0.021 0.225 0.0150.30 0.12 0.375 0.20.55 0.875 0.4 0.225import numpy as np a = np.array([1,2,3]) b = np.array([4,5,6]) You may need to use NumPy methods to answer the following questions. What is the cross product of the two vectors a and b given above? What is the dot product of the two vectors a and b given above?Complete the method endsInFive that takes as arguments a 2D-array of integers and an integer value that represents a column index in the array. endsInFive returns the number of values in the column that end in 5. It is possible that the array is ragged, meaning that the number of columns in each row is different. For example, 2 is returned if the following 2D-array is passed as the first argument of endsInFive and the integer 3 as the second argument (the values 25 and 115 end in five at column index 3).
- Write Java code to find the lowest value in a 2 dim array.Write a hangman game that randomly generates a word andprompts the user to guess one letter at a time, as presented in the sample run.Each letter in the word is displayed as an asterisk. When the user makes a correctguess, the actual letter is then displayed. When the user finishes a word, displaythe number of misses and ask the user whether to continue to play with anotherword. Declare an array to store words, as follows:// Add any words you wish in this arrayString[] words = {"write", "that",...}; (Guess) Enter a letter in word ******* > p↵Enter(Guess) Enter a letter in word p****** > r↵Enter(Guess) Enter a letter in word pr**r** > p↵Enterp is already in the word(Guess) Enter a letter in word pr**r** > o↵Enter(Guess) Enter a letter in word pro*r** > g↵Enter(Guess) Enter a letter in word progr** > n↵Entern is not in the word(Guess) Enter a letter in word progr** > m↵Enter(Guess) Enter a letter in word progr*m > a↵EnterThe word is program.
