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…
Implement a complete calculator system in JAVA and GUI. implement add, sub, multiply, divide in your system. You have to add overloaded method for float and integer arithmetic. (assignment 3 question 1) calculator should also calculate square, power, square root functions as well. you must implement the GUI and styling in calculator. (10)

The class should have suitable constructors, get/set methods, and the toString method. Design and implement another Java class named BookShelf which has an ArrayList data member named bookList to store books. The class should have suitable constructors, get/set methods, and the toString method, as well as methods for people to add a book (prototype: addBook(Book book)), remove a book (prototype: removeBook(Book book)), and search for a book (prototype: findBook(Book book)). Test the two classes by creating a Bookshelf object and five Book objects. Add the books to the bookshelf. Display the contents of the bookshelf. Test the removeBook and findBook methods as well.

A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Problem Statement# You are given an interface Addition which contains a method signature int add(int num1, int num2). You need to write a class called Calculator which implements the Addition interface. The add(int, int) method takes two integers and returns their sum. Input# Calls the add(int, int) method by passing num1 and num2. Output# Returns the addition of num1 and num2.arrow_forward
- Exercising a challenge Read the footnote on the asList method for Arrays. Locate and read the sections on class variables and class methods later in this chapter. Explain how this works in your own words.arrow_forwardIn writing a general-purpose sort method in Java, the sort method needs to compareobjects. There are two ways to give the sort method the code to compare objects,implementing the interfaces Comparable and Comparator respectively. Extend Article class toimplement Comparable interface so that the default sorting of the Articles is by its volumearrow_forwardFor the first part of this lab, copy your working ArrayStringList code into the GenericArrayList class.(already in the code) Then, modify the class so that it can store any type someone asks for, instead of only Strings. You shouldn't have to change any of the actual logic in your class to accomplish this, only type declarations (i.e. the types of parameters, return types, etc.) Note: In doing so, you may end up needing to write something like this (where T is a generic type): T[] newData = new T[capacity]; ...and you will find this causes a compiler error. This is because Java dislikes creating new objects of a generic type. In order to get around this error, you can write the line like this instead: T[] new Data = (T[]) new Object[capacity] This creates an array of regular Objects which are then cast to the generic type. It works and it doesn't anger the Java compiler. How amazing! Once you're done, screenshot or save your code for checkin later. For the second part of the lab,…arrow_forward
