Given a class Square with an instance variable width, provide a recursive getArea method. Construct a square whose width is one less than the original and call its getArea method. Make a resource class that contains all of the methods and make a driver class in a separate file, and the driver class only needs to call those methods. The driver class needs to have only 5 lines of code. The code will need to be written in Java. Please help me with exactly what I asked for help

53. Write a class with two instance variables, representing an old password and a new password. Write a recursive method that returns the number of places where the two passwords have different characters. The passwords can have different lengths. Write another, nonrecursive method returning whether the two passwords are sufficiently different. The method takes an int parameter indicating the minimum number of differences that qualify the passwords as being sufficiently different. Your program should include a client class to test your class.

Please write a Java program with at least two classes. Use a circle to represent it! The class should have at least one non-static setter method and one non-static getter. Implement at least one method test that invokes the setter method and the corresponding getter method so that the value out == the value in!

Implement the Solver class. In doing so, you are allowed to define other classes to help you (as well as use "built-in" Java classes or the book’s classes). The point of the solver class is the solve method which takes a board/puzzle configuration represented as a 2D array of booleans and returns a char array containing a minimal sequence of moves that will lead to the solved board (all the cells around the edges being filled). The board configuration is passed in as a 5-by-5 boolean array of Booleans with exactly 16 true cells (filled) and 9 false cells (empty). The solve method then returns an array of characters representing a minimal sequence of moves that solves the puzzle. In other words, if the characters from the returned array are used in order as input to the move method on the Board object representing the initial configuration, the resulting board configuration represents the solved board. Furthermore, the solution must be minimal in the sense that there are no solutions...

Write a java class method named capitalizeWords that takes one parameter of type String. The method should print its parameter, but with the first letter of each word capitalized. For example, the call capitalizeWords ("abstract window toolkit"); will produce the following output: Abstract Window Toolkit

Can I get a help with this in Java please? Introduce a new class, called Borrower to the project. Its purpose is to represent the borrower of the CD. It should have two fields surname and libraryId; where the latter is a mix of letters and numbers, and a suitable constructor with parameters for only these two fields in the order specified above as well as appropriate accessor methods.

In Java, please. Complete the Course class by implementing the findStudentHighestGpa() method, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. (Hint: getGPA() returns a student's GPA.) Note: For testing purposes, different student values will be used. Ex. For the following students: Henry Nguyen 3.5 Brenda Stern 2.0 Lynda Robison 3.2 Sonya King 3.9 the output is: Top student: Sonya King (GPA: 3.9) LabProgram.java import java.util.Scanner; public class LabProgram { public static void main(String args[]) { Scanner scnr = new Scanner(System.in); Course course = new Course(); int...

Implement the following in the .NET Console App. Write the Bus class. A Bus has a length, a color, and a number of wheels. a. Implement data fields using auto-implemented Properies b. Include 3 constructors: default, the one that receives the Bus length, color and a number of wheels as input (utilize the Properties) and the Constructor that takes the Bus number (an integer) as input.
