Exercise 2: Write array methods that carry out the following tasks for an array of integers by creating and completing the "ArrayMethods" class below. Add documentation comments for each method. Provide a test program called Lab5_yourID.java" that tests methods of ArrayMethods class. In your test program, use random class to generate array values. public class ArrayMethods

In javacode: Use ArrayList to create an array called myAL of type integer. --Fill the array with the values 5, 10, 15, 22, 33. --Print the array (use enhanced for loop). --Insert the value 25 between 10 and 15 and print the array.--Remove 2 elements on index 1 and 3 and then print the array.--Print if the array contains the value 123 or not.--Print the index of the element 22.--Print the size of the array.

Part 2: Coding 1. Write a complete Java program named FindAverage that contains the following: a. A main method that asks the user to provide the number of rows and columns for a 2- dimensional array of integers. b. A main method calls the getArray() method that creates the 2D array of specified size and populates it with random values from 0 to 100. c. A main method prints the elements of the 2D array created by getArray(). d. A main method calls the printAverage method that will: i. Receive the two-dimensional array as input ii. Calculate the average of elements in this array iii. Display the average on the console. The average of all elements should be formatted as xxx.XX. Hint: you can print the 2D array at any point in the program using either traditional for loop, foreach loop or available methods in java.util package. e. Add comments to your program. Start your program with the following header: *** *** ***** /**** ***

Please assist with the attached question using Java language. Thanks.

Write an application that prompts the user to enter nine integers and then store those nine integers in an array. Display the integers from first to last, and then display the integers from last to first. You do not have to sort them, just display the order entered and the reverse order entered. (In JAVA)

Thank you. Plz provide a screenshot of the code. Further I want to write method 4 and called method 3(u just wrote) from method 4. Method 4: A method to count the occurrences of each value in an array takes one parameter, an array of integers returns an array containing the number of times each value occurs in the parameter array

Java programming help please. Main and other class of code is below. Thank you so so much. i have to Write a program that does the following: You have an array of integers with positive and negative values. using one ourArray object (will post code of "ourArrary" below) , and in two loops maximum, How can you reorganize the content of the array so that all negative numbers are on one side and the positive numbers are on the other side. [-3, 2, -4, 5, -6, -8,-9, 7, 13] The output should be [-3, -4, -6, -8, -9, 2, 5, 7, 13] Our array code: public class ourArray<T> implements iQueue{ private T[] Ar; private int size = 0; private int increment = 100; //default constructor @SuppressWarnings("unchecked") public ourArray () { Ar = (T[]) new Object[100]; size = 0; } //constructor that accepts the size @SuppressWarnings("unchecked") public ourArray (int n) { Ar = (T[]) new Object[n]; size = 0; } //constructor that specifies the initial capacity and the increment...
