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() 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. Add a comment to your class Moth that explains how you can make the Moth immobile after 10moves.

Giving the following code class Rectangle: def init (self, I, w): self.length = / self width = w def rectangle area(self): return self.length*self width def rectangle _perimeter(self): return (self.length+self.width)*2 RI = Rectangle(20, 12) print(Rl .rectangle_area()) print(Rl .rectangle_perimeter()) Answer the questions How many classes we have on the above example? What is the role of the method init (.)? How many methods are defined? How many objects are created? How we invoke any method. Cite an example from the above code? Instanciate 2 rectangles using your Rectangle class, and draw schema representing the namespaces

Write a program that displays heads (H) or tails (T) for each of ninecoins, as shown in Figure 12.31c–d. When a cell is clicked, the coin is flipped.Write a custom cell class that extends Label. In the initializer of the class, bindthe event <Button-1> with the method for flipping the coin. When the program starts, all cells initially display H.

Write a program that calls methods for each of the following mini problems from its main method. Us a single Scanner for the program declared in the class asprivate Static Scanner keyboard = new Scanner(System.in); Write a method that reads two strings from the user’s keyboard. Display each string, along with its width, on two separate lines. Then create a new string by joining the two strings with a space between them. Display the new string and its length on a new separate line. 2. Write a method that reads a line of text from the keyboard and then displays the line, but with the first occurrence of hate changed to love. For example, a possible sample dialogue might beEnter a line of text.I hate you.I have rephrased that line to read:I love you.You can assume that the word hate occurs in the input. If the word hate occurs more than once in the line, your program will replace only its first occurrence. 3. Write a method that asks the user to enter a favorite color, a favorite…
