AVA code OVERVI EW This is a review exercise, so the primary goal of the exercise is to get your mind working and in the correct space.In this activity you will create a imaginary grid of locations that goes from −?≤?≤?, −?≤?≤?, with the coordinate (0,0) being "home". On this grid you will keep track of various animal objects as they move around the grid. Make sure that all animals stay within that grid at all timesincluding when they are created. Zwill be the map size and will control the highest number allowed on themap before wraping around. Using Java, create the following classes and primary program that uses the classes that you developed. INS T RUCT IONS Create the following classes. A N I MA L C LA SS Create an Animal class. Each animal has a name, an x and y integer coordinate. The Animal class should have at minimum the following methodsbelowbut you may want to add more if necessary: Also note, everyanimal will need to have to have “z”passed to it so that it knows how big the…
dict1 = {(1,1,1):"red", (2,1,-1):"green", (0,-1,1):"red", (0,0,-2):"blue"}In this case, there are 2 red points, and their centroid is at ( (1+0)/2, (1-1)/2, (1+1)/2 ) = (0.5, 0, 1)Considering that in this example there is only one green and one blue point, they are representing the respective color's centroid. Hence, your function should return the following dictionary:{"red":(0.5,0.0,1.0), "green":(2.0,1.0,-1.0), "blue":(0.0,0.0,-2.0)}

✓ Exercises Exercise: Write a method _ and _ that computes the region representing the intersection of two regions. Exercise: Write a method _contains__, which checks whether a n-dimensional point belongs to the region. Remember, a point belongs to the region if it belongs to one of the rectangles in the region. ✓ Membership of a point in a region #@title Membership of a point in a region def region_contains (self, p): ### YOUR SOLUTION HERE Region._contains = region_contains [ ] # Tests 10 points. assert (2, 1) in Region (Rectangle((0, 2), (0, 3)), Rectangle((4, 6), (5,8))) assert (2, 1) not in Region (Rectangle((0, 1), (0, 3)), Rectangle((4, 6), (5, 8))) Exercise: Write a method _le_ for regions such that R <= S if the region R is contained in the region S. You can test this by checking that the difference between R and S is empty.
In this assignment, you will implement part of a bigger program that deals with jewelry. You must submit the full implementation for the following interface: public interface JewelryBagInterface { public boolean addJewelryItem(int id, Jewelry j, double weight); public boolean removeJewelryItem(int id); public double getTotalWeight (); public double getTotalPrice (); public double getTotalGoldWeight (); public double getTotalSilverWeight (); public double getTotalBronzeWeight (); public void printBagContents(); public void setMaximumWeight (double max_weight); public void removeAllGoldItems(); public void removeAllsilverItems (); public void removeAllBronzeItems (); public int getTotalNumberOfitems(); public int getTotalNumberOfGoldItems (); public int getTotalNumberOfSilverItems (); public int getTotalNumberOfBronzeItems (); The interface JewelryBag java is available on Moodle (including the method descriptions).

The interface Range is defined below:public interface Range{ void setLimits(int x, int y); int getNumber();}Implementations of Range should exhibit the following behaviour:• The setLimits method should store its parameter values somewhere to serve as the lower and upper limits of the range appropriately.• A call to getValue should return an integer that is always greater than or equal to the lower limit and less than or equal to the upper limit.The class RandomInteger is an implementation of the interface Range. It also has the following features:• It has two fields of int type, low and high, to record the lower and upper limits of the range, respectively.• It has single constructor method that takes two integers and stores them in the appropriate fields. Note: You should make use of the setLimits method.• A call to the method getNumber should return a random number that is always within the range, i.e. greater than or equal to the lower limit and less than or equal to the upper limit.…
#Testing Please test my code and see if it meet the follwing needs: The class should implement the Comparable interface. Circle one is less than Circle two if the radius of Circle one is less than the radius of Circle two. The two Circles are equal if they have the same radius. Circle one is larger than Circle two if its radius is larger. If circle One.compareTo circle Two <> 0 The Test Class displays a menu that allows the user to: Enter a Circle (the user only needs to enter the radius). Print all Circles (print the toString for each Circle in the ArrayList). Quit To adda a circle Cases: The ArrayList is empty The new circle is less than the first circle, add it at the beginning. The circle is greater than the last circle, add it at the end The new circle belongs somewhere in the middle. import java.lang.Math;public class Circle implements Comparable<Circle> {private double radius;public Circle(double radius) {this.radius = radius;}public double findArea()…
