Write method findZero, as started below. findZero should return the index of the first element of array A that contains the value zero, starting from position 0 up through position pos. If no element of A from position 0 to position pos contains the value zero, then findZero should return –1. For example:(in java) Array (A) Position (pos) Value returned by findZero(A, pos) 1 0 2 5 6 0 -1 1 0 2 5 6 1 1 1 0 2 5 6 2 1 1 0 2 0 6 2 1 1 0 2 0 6 4 1 1 2 3 4 5 4 -1 Complete method findZero below.

Write class name Student Management having array of students and count of students as attribute. There should be method for the following: Add new Student in Array Remove a Student from Array using Name (of Student) Sort the Students in array using Name (ascending order) Sort the Students in array using Age (ascending order) Sort the Students in array using CGPA (ascending order) Reverse the order of the Students in array Display information of all Students in array (from zero index to last index) Note.This is a java program
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 program java 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.
Create an array of 10 elements. Initialize it as follows. INITIAL array : 58 24 13 15 63 9 8 81 1 a 78 Now split it into middle and store the elements in two different arrays. E.g.-After spliting : 58 24 13 15 b 63 9 8 81 1 c 78 Now create another array “d” of size 5. Fill this array by adding elements of array “b” and array “c”. 67 32 94 16 d 141
Write the method sum2D() which accepts a two dimensional integer array and returns the sum of all the elements of the array.
Complete 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]…
Return the maximum value from the provided integer array. You may assume that all values in the array will be non-negative. getMax([1]) → 1getMax([0, 3, 2, 12, 4]) → 12getMax([15, 3, 1, 7, 2]) → 15 public int getMax(int[] nums) { Write your code in here using this outline.}
3. Remove an element from an array Consider an array named source. Write a method/function named remove( source, size, idx) that removes the element in index idx of the source array. You must execute the method by passing an array, its size and the idx( that is the index of the element to be removed). After calling the method, print the array to show whether the element of that particular index has been removed properly. Example: source=[10,20,30,40,50,0,0] remove(source,5,2) After calling remove(source,5,2) , printing the array should give the output as: [ 10,20,40,50,0,0,0] Use Python language
