Write a Java program with at least two classes. Use a circle object to represent it. The class must offer at least one (non-static) setter method and one (non-static) getter method. Implement at least one test that invokes the setter method and the corresponding getter method so that the value out == the value in. Also use assert.Equal(60, circle1.getCircumference(), 10); and assert.Equals(10, circle1.get Radius(), 0.1); for radius

1) Implement a class Moth that models a moth flying along a straight line. The moth hasa position, which is the distance from a fixed origin. When the moth moves toward apoint of light, its new position is halfway between its old position and the position ofthe light source. Find the instance variable(s), define and implement the constructor(s), then supplythe following methods:- public void moveToLight(double lightPosition) - public double getPosition()2) Document your class, generate Javadoc documentation and produce a test program ‘MothTester’that construct a moth, move it toward a couple of light sources, and check that the moth’s positionis as expected. 3) Add a comment to your class Moth that explains how you can make the Moth immobile after 10moves.

A java program, with a class Rectangle with attributes length and width , each of which defaults to 2. Providemethods that calculate the rectangle’s perimeter and area. It has set and get methods for bothlength and width . The set methods should verify that length and width are each floating-pointnumbers larger than 10.0 and less than 40.0. Write a program to test class Rectangle .

in java Given main(), define the Team class (in file Team.java). For class method getWinPercentage(), the formula is:wins / (wins + losses). Note: Use casting to prevent integer division. For class method printStanding(), output the win percentage of the team with two digits after the decimal point and whether the team has a winning or losing average. A team has a winning average if the win percentage is 0.5 or greater. Ex: If the input is: Ravens 13 3 where Ravens is the team's name, 13 is the number of team wins, and 3 is the number of team losses, the output is: Win percentage: 0.81 Congratulations, Team Ravens has a winning average! Ex: If the input is: Angels 80 82 the output is: Win percentage: 0.49 Team Angels has a losing average.

Java allows for methods to be chained together. Consider the following message from the captain of a pirate ship: String msg1 = " Maroon the First Mate with a flagon of water and a pistol! ";   We want to change the message to read the message msg1:   String msg2= “Maroon the Quartermaster with a flagon of water.”   Three changes need to be made to adjust the string as desired:   Trim the leading and trailing whitespace. Replace the substring First Mate with Quartermaster. Remove "and a pistol!" Add a period at the end of the sentence. A “chaining1” method which will apply in sequence 4 operations to perform the above. We will use the trim, replace, and substring methods, in this order. Thus the chaining1 method will receive a string msg1 and return a string msg2. Make sure msg2 is printed. A “chaining2” method which will apply the 4 operations above in one single statement. Thus the chaining2 method will receive a string msg1 and return as string msg2. Make sure msg2 is printed

Write a Java class called Rectangle that represents a rectangular, two-dimensional region. In thislab you learn overriding a system method. Create a default, empty constructor.Set the double values for the ‘x’ ‘y’ ‘height’ ‘width’ in the Rectangle objects whose top-leftcorner is specified by the given ‘x’ and ‘y’ coordinates and by the width and height. Your classwill need to use setters and getters with these 4 values. Recall we discussed in class lectures toput values into the instantiated object.Override the ‘toString()’ base method to produce the following information inside the singlequotes. EXAMPLE OF OUTPUT=‘Rectangle [x=2.5, y=13.0, height=14.0, width=4.0] Area is 54.0’Write a test program called TestRectangle that creates objects of the Rectangle class called rect1and rect2. Assign values to the fields of these objects. Print out these Rectangle objects usingSystem.out.println() from inside the main() method (Hint: this will utilize the overridden‘toString()’ in the Rectangle…

Modify class Time2 (pasted below) to include a tick method that increments the time stored in a Time2 object by one second. Provide method incrementMinute to increment the minute by one and method incrementHour to increment the hour by one. Write a program that tests the tick method, the incrementMinute method and the incrementHour method to ensure that they work correctly. Be sure to test the following cases: a. incrementing into the next minute, b. incrementing into the next hour and c. incrementing into the next day (i.e., 11:59:59 PM to 12:00:00 AM).   public class Time2 {private int hour; // 0 - 23private int minute; // 0 - 59private int second; // 0 - 59 //no-argument constructor that initializes each instance variable to zeropublic Time2() {this(0, 0, 0); //invoke constructor with three arguments}//constructor, hour supplied, min and sec defaulted to 0public Time2(int hour) {this(hour, 0, 0); //invoke constructor}//hour and min suppliedpublic Time2(int hour, int minute)…

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…

Use Java program to add a method printReceipt to the CashRegister class. The method should print the prices of all purchased items and the total amount due. Hint: You will need to form a string of all prices. Use the concat method of the String class to add additional items to that string. To turn a price into a string, use the call String.valueOf(price). Also, the payment information will need to be the same as the price information.  Here is the CashRegister class: /**   A cash register totals up sales and computes change due.*/public class CashRegister{   private double purchase;   private double payment;    /**      Constructs a cash register with no money in it.   */   public CashRegister()   {      purchase = 0;      payment = 0;   }    /**      Records the sale of an item.      @param amount the price of the item   */   public void recordPurchase(double amount)   {      purchase = purchase + amount;   }    /**      Processes a payment received from the customer.      @param…

Can you do this please? Thank you
