Question 8

Which of the following is FALSE about arrays on Java.

◯ A java array is always an object

◯ None of the above

◯ Length of array can be changed after the creation of an array

◯ Arrays in Java are always allocated on heap

 

Recursion Question 5. In the following question, you will be asked to program the following using recursion. If you have an iterative solution, you may use it, but the most you can get for the question will be half credit. (5) points) Consider the following mathematical function h which operates on integers. (1, if n < 2 h(n) = n(n-1) +n if n > 2 and n is even han -2) +2*n if n > 2 and n is odd In Java, use recursion to write a method h which takes as input an int n and returns h (n). public static int h(int n) {

20. How many arrays are created in the following code? int[] foo = {1,2,3); int[] bar = foo; int[] m = foo; m = new int [10); int[] copyOfM = m;

Coding Question - Sorted array You are to write a method that takes as input an array of integers, returns true if the array is sorted, and returns false otherwise. For example, if a is the array {1,12,5,6,2,87}, then the method has to return false as it is not sorted. Use the 5 following questions to "write" your code. Pay close attention to how your answers group together with each other. 33. Line 1 (A) public static boolean Sorted (int[] a) { (B) public static void Sort (int[] a) { (C) public static int[] Sorted (int a) { (D) public static boolean Sorted() { (E) public static void main(String[] s) {
