Math class and its different methods

Java math class consists of arithmetic math methods that performs basic numeric operations such as finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions, etc. The Math library functions can be accessed using the header Java.lang.Math. These math methods under Java math class are for our convenience.

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…

Suppose I have implemented classes C and D, where D extends C. “Just for fun” I want to write code such that a variable of type D refers to an object of type C. I’m allowed to use assignments, casts and so on. Explain why Java will make it impossible for me to achieve my goal.
Write a class named NameAndCount for recording a String data name and an int data named count. A constructor for the class takes two values, one for the name and the other for the count, and stores the two values in the instance variables. The class must be comparable, with the declaration of implements Comparable<NameAndCount>. The class has a “getter” for the name, named getName, and a “getter” for the count, named count. For “setters”, there is a method named increment that increases the value of count by 1. There is another instance method equals, which receives a String data as its parameter, and returns a boolean value indicating whether or not the contents of the String data is equal to the contents of name. Additionally, the class must implement the compareTo method, which returns the result of comparing the values of count. please write java code for above question and please send me the screenshot of the output format
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…

For this assignment, your implementation plan must include at least one class with public and private sections. For assistance with classes, see sections 6.2, "Using a Class," and 6.3, "Defining a Class," in zyBooks. For this assignment, we recommend using Maps (section 11.4 in zyBooks) for implementation. Maps do require precise coding syntax. However, you can choose a different implementation option. Apply industry standard best practices such as in-line comments and appropriate naming conventions to enhance readability and maintainability. Remember that you must demonstrate industry standard best practices in all your code to ensure clarity, consistency, and efficiency. This includes the following: Inserting in-line comments to denote your changes and briefly describe the functionality of the code Using appropriate variable, parameter, and other naming conventions throughout your code Optional Challenge: User Input ValidationValidating user input is a coding best…
