QUESTION 1 Using the following declarations and a member of the Array class, int [ ] bArray = new int [10]; int location; Using a method in the Array class, write a statement that would change the order of the elements in the bArray array. The contents of the first cell should hold what was in the last cell. The second cell should hold what was in the next to last cell. __________________________ HINT: You must write the full statement...
please use eclipse the sample output is incorrect CPS 2231 Chapter 8 Lab 1 Spring 2019 1. Write a class, SumOrRows. The main method will do the following methods: a. Call a method, createAndFillArray which: defines a 2 dim array of 3 rows and 4 columns, prompts the user for values and stores the values in the array. b. Calls a method, printArray, which: prints the Array as shown below c. Cails a method, calcSums, which: returns à 1 dimensional...

SELF-CHECK Why did the first version of method search that passed the first test itemNotFirstElementInSingleElementArray contain only the statement return −1? Assume the first JUnit test for the findLargest method described in Self-Check exercise 2 in section 3.4 is a test that determines whether the first item in a one element array is the largest. What would be the minimal code for a method findLargest that passed this test? PROGRAMMING Write the findLargest method described in self-check exercise 2 in...
5. (40 Points) Write a complete Java class named ArrayMethods that implements the methods listed below. All the methods accept the following parameters: Parameters: intar An array of int values. int firstIndex The index of the first element to include in the sum. int lastIndex The index of the last element to include in the sum. Please note that all methods must verify the validity of first Index and lastIndex. public static int sum(int[] arr, int first Index, int lastIndex)...
HW58.1. Array Merge Sort You've done merge (on Lists), so now it's time to do merge sort (on arrays). Create a public non-final class named Mergesort that extends Merge. Implement a public static method int[] mergesort(int[] values) that returns the input array of ints sorted in ascending order. You will want this method to be recursive, with the base case being an array with zero or one value. If the passed array is null you should return null. If the...
Complete an Array-Based implementation of the ADT List including a main method and show that the ADT List works. Draw a class diagram of the ADT List __________________________________________ public interface IntegerListInterface{ public boolean isEmpty(); //Determines whether a list is empty. //Precondition: None. //Postcondition: Returns true if the list is empty, //otherwise returns false. //Throws: None. public int size(); // Determines the length of a list. // Precondition: None. // Postcondition: Returns the number of items in this IntegerList. //Throws: None....

Create a program called GeneralizedBubbleSort that will make use of the Comparable Interface in the same way it is used in the GeneralizedSelectionSort. You should use the attached ComparableDemo to test your program. public class ComparableDemo { public static void main(String[] args) { Double[] d = new Double[10]; for (int i = 0; i < d.length; i++) d[i] = new Double(d.length - i); System.out.println("Before sorting:"); int i; for (i = 0; i < d.length; i++) System.out.print(d[i].doubleValue( ) + ", ");...
Complete the program that solves the Eight Queens problem. The program’s output should look similar to: |1|0|0|0|0|0|0|0| |0|0|0|0|0|0|1|0| |0|0|0|0|1|0|0|0| |0|0|0|0|0|0|0|1| |0|1|0|0|0|0|0|0| |0|0|0|1|0|0|0|0| |0|0|0|0|0|1|0|0| |0|0|1|0|0|0|0|0| Use the Queens class given. In your implementation of the Queens class, complete the body of all methods marked as “To be implemented in Programming Problem 1.” Do not change any of the global variable declarations, constructor or placeQueens methods. Here is what I have so far with notes of what is needed. public class Queens...
