FOR JAVA Write a method that takes a one dimensional integer array, an integer (as index) and another integer (as number). Your program must insert the number into the given index, shift the rest of the elements to the right, and return the new array. For instance, if we want to insert the number 0 into position 3 of {1, 2, 3, 4, 5}, your method must return {1, 2, 3, 0, 4, 5}.
Write a Java class that creates a 3x4 array of 12 random ints between 0 and 100. Write a method to return the sum of the elements in the last column of each row in the two-dimensional array.
Write a method sumArray that calculates and returns the sum of a given array of double values
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: 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. Assume that it is called only with values that satisfy its assumptions as stated below. // Description: Returns smallest index k // such that (0 <= k <= pos) and (A[k] == 0) // Assumptions: 0 <= pos < A.length public int findZero(int[] A, int pos) {
The rotateLeft method takes an array of integers, and an integer number of places, and returns a new copy of the array that contains a "rotated" version of the input array. Rotation means that elements have been shifted leftwards by that number of places, moving elements off one end of the array and onto the other end. For example, [11, 12, 13, 14, 15] rotated left by 2 places results in [13, 14, 15, 11, 12].
FOR JAVA Write a method that takes an integer array and returns the difference between the sum of even indexed elements and the sum of odd indexed elements in that array.
Given an ArrayList of integers, return an ArrayList where all the odds are before the evens in the order that they occur. public ArrayList<Integer> solution(ArrayList<Integer> nums) {ArrayList<Integer> finalList = new ArrayList<>();int index = 0;for (int i = 0; i < nums.size(); i++) {if (nums.get(i) % 2 == 1) {finalList.add(index, nums.get(i));index++;} elsefinalList.add(nums.get(i));}return finalList;} This is my failing code. for [1.-3.3] where [1,3,-3] is being returned
Write the method printTail() method that accepts an array of integers and an integer index as parameters and prints all the array elements starting from the index passed. For example if printTail(x,5) is invoked, it should print all the elements of the array x starting at x[5].
Write a program in java that randomly fills in 0s and 1s into an n-by-n matrix, prints the matrix, and finds the rows and columns with the most 1s. (Hint: Use two ArrayLists to store the row and column indices with the most 1s.)
FOR JAVA Write a method that takes a one dimensional integer array and an integer, and returns the index of the integer in the array. If the integer is not in the array, your program must return -1. If there are multiple occurrences of that number, your program must return the smallest index. Repeat the second question, but if there are multiple occurrences of the number, your program must return the largest index instead of the small- est.
Write the method sum2D() which accepts a two dimensional integer array and returns the sum of all the elements of the array.
Write a java method named sumArray that accepts an array of double values and returns the sum of the values stored in the array.
