Write a Java Program to define a class, describe its constructor, overload the Constructors and instantiate its object.

Please write a Java program with at least two classes. Use a circle to represent it! The class should have at least one non-static setter method and one non-static getter. Implement at least one method test that invokes the setter method and the corresponding getter method so that the value out == the value in!

What are some of the benefits of using an ADT bag in Java? Provide an example that illustrates when using a bag would be useful. In your answer, specifically think of and give a real-life scenario where: The Bag ADT can be useful Using Bag ADT is better than the alternatives Please and thank you

Create a new project called Trunc.java . Trunc.java shouldloop around getting floating point (i.e. type double) numbers and displayingboth the number and the running total to the nearest whole number. Theprogram will finish when a number is entered outside of the range -100 to100. The program should use methods to check whether the number is in thisrange, and then rounded to the nearest whole number. (NOTE: Not touse the JAVA Round method, write own method by modifying thecalcTwoDPs method in TwoDPs.java). //TwoDPs.java//Displays running total of numbers in lines of standard input correct to two decimal places.//Uses an out of range number (<-100 or >100) to quit. import java.util.Scanner; public class TwoDPs { public static void main(String[] args) {Scanner input = new Scanner(System.in);double total = 0;boolean flag = true;System.out.println("Use an out of range entry (< -100 or > 100) to quit.");while (flag) {System.out.println("Enter a floating point number on a…

There are three main operations on rectangles: intersection, union, and difference. Among them, only intersection is guaranteed to return another rectangle. In general, the union of two rectangles is... two rectangles, and the difference between two rectangles is ... a whole lot of rectangles, as we will see. We let you implement rectangle intersection. Of course, the intersection is defined only if the rectangles have the same number of dimensions. The intersection is computed by taking the intersection of the intervals of the two rectangles for corresponding dimensions. If one of the intervals is empty, you should return None. [] # @ title Rectangle intersection def rectangle_and(self, other): if self.ndims != other.ndims: raise TypeError("The rectangles have different dimensions: {} and {}".format( )) self.ndims, other.ndims ### YOUR SOLUTION HERE Rectangle. _and_ = rectangle_and [ ] r1 = Rectangle((2, 3), (0, 4)) r2 = Rectangle((0, 4), (1, 3)) draw rectangles (r1, r2) draw…
