This question involves reasoning about arrays of integers. You will write two static methods, both of which are in a class named ArrayTester. public class ArrayTester { /* Returns an array containing the elements of column c of arr2D in the same order as they appear in arr2D. Precondition: c is a valid column index in arr2D. Postcondition: arr2D is unchanged. */ public static int [] getColumn (int [1 [] arr2D, int c) { /* Your code goes here */ } /* Returns true if and only if every value in arr1 appears in arr2. Precondition: arr1 and arr2 have the same length. • Postcondition: arr1 and arr2 are unchanged. */ public static boolean hasAllValues (int [] arr1, int [] arr2) { /* implementation not shown */ } // Returns true if arr contains any duplicate values; false otherwise. public static boolean containsDuplicates (int [] arr) { /* implementation not shown */ } } Write a static method getColumn, which returns a one-dimensional array containing the elements of a single column in a two-dimensional array. The elements in the returned array should be in the same order as they appear in the given column. The notation arr2D [r] [c] represents the array element at row r and column c. The following code segment initializes an array and calls the getColumn method. int[][] arr2D = { { 0, 1, 2 } , { 3, 4, 5 } , { 6, 7, 8 } , { 9, 5, 3 } }; int[] result = ArrayTester.getColumn (arr2D, 1) When the code segment has completed execution, the variable result will have the following contents: {1, 4, 7, 5} public static int[] getColumn (int[] arr2D, int c) { CODE TEXTBOX }
