Implement the static method declared as follows:
/** * Divides {@code n} by 2. * * @param n * {@code NaturalNumber} to be divided * @updates n * @ensures 2 * n <= #n < 2 * (n + 1) */ private static void divideBy2(NaturalNumber n) {...} |

Implement the static method declared as follows:
/** * Checks whether a {@code String} is a palindrome. * * @param s * {@code String} to be checked * @return true if {@code s} is a palindrome, false otherwise * @ensures isPalindrome = (s = rev(s)) */ private static boolean isPalindrome(String s) {...} |
Recursion needs to be used for both of these, and the NaturalNumber class needs to be used for the top method.
/** * Checks whether a {@code String} is a palindrome. * * @param s * {@code String} to be checked * @return true if {@code s} is a palindrome, false otherwise * @ensures isPalindrome = (s = rev(s)) */ private static boolean isPalindrome(String s) { if(s.length() <= 1) { return true; } else { if(s.charAt(0) != s.charAt(s.length()-1)) { return false; } else { return isPalindrome(s.substring(1, s.length()-1)); } } }

Implement the instance method flip declared as follows (this is a Queue): /** * Reverses ("flips") {@code this}. * * @updates this * @ensures this = rev(#this) */ public void flip(); Rewrite flip, including the contract, so that it is a static method. http://web.cse.ohio-state.edu/software/common/doc/
A palindrome is a word, phrase, or sequence that reads the same backward as forward, e.g., madam or nurses run. In this program, ask the user to input some text and print out whether or not that text is a palindrome. Create the Boolean method isPalindrome which determines if a String is a palindrome, which means it is the same forwards and backwards. It should return a boolean of whether or not it was a palindrome. Create the method reverse...
IN JAVA. Implement a method, public static boolean isPalindrome(String) to determine whether the specified String is a palindrome or not. A palindrome is a phrase that reads the same forwardand backward; not including punctuation, spaces, or letter case. Some example palindromes include: Just the method please..
Java Software Originals, Inc., has been hired by Eaton Wright, the "pizza king", to help automate a new chain of pizza delivery stores. SOI's system engineering staff have asked you to implement a prototype for the telephone operator's console. To start the project they have assigned you to implement the following two static methods (the first of which will be used to read files containing menus of pizza sizes and their prices, and pizza toppings and their prices; and the...
The code is in JAVA public class CheckBST { //method to implement public static boolean isValidBST(TreeNode root) { } public static void main(String[] args) { TreeNode a = new TreeNode(1); TreeNode b = new TreeNode(2); TreeNode c = new TreeNode(3); a.left = b; a.right = c; System.out.println(isValidBST(a)); TreeNode d = new TreeNode(2); TreeNode e = new TreeNode(1); TreeNode f = new TreeNode(3); d.left = e; d.right = f; System.out.println(isValidBST(d)); } } TreeNode.java class TreeNode { int val; TreeNode left; TreeNode...
Modification to be completed by group member 4: In the processLineOfData method, write the code to handle case "M" of the switch statement such that: A Manager object is created using the firstName, lastName, salary, and bonus local variables. Notice that salary and bonus need to be converted from String to double. You may use parseDouble method of the Double class as follows: Double.parseDouble(salary) Call the parsePaychecks method in this class passing the Manager object created in the previous step...
In the processLineOfData method, write the code to handle case "H" of the switch statement such that: • An HourlyEmployee object is created using the firstName, lastName, rate, and hours local variables. Notice that rate and hours need to be converted from String to double. You may use parseDouble method of the Double class as follows: Double.parseDouble(rate) Call the parsePaychecks method in this class passing the Hourly Employee object created in the previous step and the checks variable. Call the...
In this lab, we will implement the Linked Bag. The bag will contain a sequence of strings. First, you need to design the Node class (Node.java). It will contain an integer data and a reference to thenext Node. The constructor of Node class receives an integer and assigns it to the data field. It also has a default constructor. Data Next Node Then we will design another class named LinkedBag (LinkedBag.java). LinkedBag class has an instance variable called firstNode of...
Modify the library program as follows: Create a method in the LibraryMaterial class that accepts a string s as a parameter and returns true if the title of the string is equal to s. Create the same method for your library material copies. Note that it will need to be abstract in the LibraryMaterialCopy class MY CODE **************************************************************** LibraryCard: import java.util.List; import java.util.ArrayList; import java.time.LocalDate; import java.time.temporal.ChronoUnit; public class LibraryCard { private String id; private String cardholderName; ...
