Create a Point classCreate a Point class as we did in the class. We'll use this to create Point objects that hold x,y coordinates of locations where we'll want to draw. Draw DotsWrite a drawDots(points) function that takes a list points as input and draws a dot on the drawing window for each Point. For example, you should be able to call your function as follows: >>> p = Point(10, 20) >>> q = Point(20, 30) >>> points = [p, q] >>> drawDots(points)
IN JAVA Create a function that takes a string and returns the number of alphanumeric characters that occur more than once. Examples duplicateCount ("abcde") → 0 duplicateCount ("aabbcde") → 2 duplicateCount ("Indivisibilities") → 2 duplicateCount ("Aa") → 0 // Case sensitive

Exercise 2. Create a Book class where: Each book contains the following information: book title book Author name, barcode (as fong integers), and book topic. o Implement an appropriate constructor(s) and all necessary get/set methods. Test Book class: o Create diffcrent book objects (at least 5 hooks) and store them in a LinkedList sorted by book barcode value Generate a unique random integer value for the barcode. Iterate through the LinkedList and print out the books' details O Create a second LinkedList object containing a copy of the above LinkedList, but in reverse order.
Java - Encapsulation Create a class Point with attributes x and y which are both integers. Create getters and setters for these attributes and implement the following methods: 1. calculateDistance() - calculates the distance from the origin to the point. Returns a double, formula is sqrt(x^2 + y^2) 2. printCoordinates() - prints "(x,y)" Ask for user inputs for x and y. Use the methods printCoordinates() and calculateDistance() respectively. Inputs 1. X 2. Y Sample Output Enter x: 20 Enter y: 15 (20,15) 25.00

Return its contents as a String. If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String. This makes it useful for displaying to the user. /** * Returns a String representation of this vector.
