Write java methods to do these tasks: a. Move even elements to the front, if not then preserving the order of the elements. Return true if all elements in array are identical. b.Remove the middle element if the array length is odd, or the middle two elements if the length is even. **Find the mean of the values in an array **Find the second-largest element in the array. **Find the median value of the values in an array

2. Rotate Left k cells Use Python Consider an array named source. Write a method/function named rotateLeft( source, k) that rotates all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateLeft(source,3) After calling rotateLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]
TASK 3 Write a Java method that returns the location of the largest element in a two-dimensional array. public static int) locatelargest(double[] a) The return value is a one-dimensional array that contains two elements. These two elements indicate the row and column indices of the largest element in the two-dimensional array. Write a Java test Program that prompts the user to enter a two- dimensional array and displays the location of the largest element in the array. Here is a sample run: Enter the number of rows and columns of the array: 3 4 -Enter Enter the array: 23.5 35 2 10 Enter 4.5 3 45 3.5 |-Enter 35 44 5.5 9.6 -Enter The location of the largest element is at (1, 2)
4. Remove all occurrences of a particular element from an array Consider an array named source. Write a method/function named removeAll( source, size, element) that removes all the occurrences of the given element in the source array. You must execute the method by passing an array, its size and the element to be removed. After calling the method, print the array to show whether all the occurrences of the element have been removed properly. nmm" Use Python Example: source=[10,2,30,2,50,2,2,60,0,0] removeAll(source,8,2) After calling removeAll(source,8,2), all the occurrences of 2 must be removed. Printing the array afterwards should give the output as: [ 10,30,50,60,0,0,0,0,0,0]
In Java (Single-Dimensional Arrays) // need a different solution than what's already in Chegg's solution Write a program that reads and fills an array with 20 integers. Then, using the array elements, calculate the data to find and display: The highest value entered. The lowest value entered. The average of the numbers entered. The sum of the numbers entered. Display this information in a readable display making the data easy to understand.
1. Shift Left k Cells Use Python Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]
Q / write a program in Fortran language to find the number of readings whose values exceed 70 mm and the percentage of these readings, as well as find the number of readings that are less than 40 mm and the percentage of these readings in the matrix AN (7 + AN if your number (N) is odd, or from the array (8 +8). AN if your number is (N) even. Notes: 1- N represents your number (meaning the student's number in the department. 2- The program must be complete (ie include FORMAT phrases) with each reading and writing statement 3- Reading items from an external file His name is the first 3 letters of the first name of your name 4- Print the elements in an external file whose name is the first 3 letters of the third name of your name 5- The answer is by printing the required program and not a picture of the solution for the purpose of correction #my number is (n=14)
TASK 1 Write a Java method that returns the index of the smallest element in an array of integers. If the number of such elements is greater than 1, return the smallest index. Use the following header: public static int indexofLargestlestelement(double[] array) Write a test program that prompts the user to enter ten numbers, invokes this method to return the index of the smallest element, and displays the index.
Carry out the following task with an array: a. Allocate an arraya of ten integers. b. Put the number 17 as the initial element of the array. c. Put the number 29 as the last element of the array. d. Fill the remaining elements with –1. e. Add 1 to each element of the array.f. Print all elements of the array, one per line. g. Print all elements of the array in a single line, separated by commas.h. Count how many elements are less than a given value (entered by user). i. Remove all elements that are less than a given value (entered by user). j. Place all elements that are less than a given value (provided by user) in another array.

Debugging challenge: Consider the code example below. This program is designed to compare the contents of two arrays: if they are equal, the program should display "TRUE," if the arrays are not equal, the program should display "FALSE". However, even when the arrays have the same value, the program always prints "FALSE", regardless of the values in arrays a and b. What is going on here? What about the program causes the comparison to always fail? int a[4] {1, 2, 3, 4}; int b[4] = {1, 2, 3, 4}; if (a == b) { display ("TRUE"); else { display ("FALSE");
Instead of utilizing an array, would it be beneficial to work with vectors instead?
JAVA QUESTION 1 Using methods and arrays, write a program that • Creates an array A of size 100 integers. Fill the array with random values should be within the range 1 to 21 inclusive • Add a method to change the data and store it in another array based on the rule: if any item is divisible by 2 then add 2 and it is divisible by 3 then add 3 else add 5. prints it out in the two arrays 5 items per line.
