Problem 2.1.5 (Find the address ranges). For each of the three main classes (A,B,C) find the precise address ranges and identify how many hosts can theoretically be in a network of the respective class. For class C please consider both the cases where classes D and E are excluded and where they are included into class C. This has proved to be very inflexible and led to poor utilization of the address space. In particular, after the (few) class-A addresses have been allocated to companies and organisations helping to pioneer the Internet, people urned to class-B addresses. However, only few organizations having a class-B address really have 65,534 different end hosts, leaving large parts of the address space un-utilized. And resorting to class-C addresses lew up routing tables in routers, straining their memory and leading to larger lookup times.

Can some pretty please help with this HW problem?
Suppose we had support for multimethods instead of or in addition to overloading. Explain how you would implement the pretty printer of Project 1 using multimethods instead of having a print() method in each class of the hierarchy. What would be the advantage of using multimethods? You can simply use the same syntax as for overloading and indicate where the multimethod dispatch happens.
Note: I asked the following question 2 days ago, and you have just sent the java code (racket trajectory) with 2 classes, I did not, what the project is about that you sent me, could you please give me an explanation about the (racket trajectory ) and how you implemented it? please! With this assignment, you’ll implement one of the problems listed below. JADE agents also.- Ant-based clustering- Fire escape scenario - Prey-predator - Covid pandemic- Motion of fluids or gases- Or Any other brilliant idea best fits with agent-based phenomenaProbability distributions (Normal, Uniform, Exponential and etc.) for Interarrival times and processing times can be calculated by third-party Java libraries such as Apache Commons.Logging created random numbers by Java and verifying them with Excel, Arena Input Analyzer or sth else will be a part of this step.

Which of the following is true? Select one: O Every class in Java implements exactly one interface. O Every class in Java (except Object) implements one or more interfaces. O Every class in Java implements zero or one interfaces. O Every class in Java implements zero or more interfaces. O Every class in Java (except Object) implements exactly one interface. O Every class in Java implements one or more interfaces. O None of these options
In Java Langauge. Thank you
what is the command subplot(2,3,5) mean? Your answer *
Every interface worth its salt must provide access to a full suite of functions. What abilities do you need to have? Is it planned to use a single method across the board? Document your claims by citing appropriate earlier research.
What is a HashMap? What is its purpose and how do you use it? Answer these questions in writing, and use the Java library documentation of Map and HashMap for your responses. Note that you will find it hard to understand everything, as the documentation for these classes is not very good. We will discuss the details later in this chapter, but see what you can find out on your own before reading on.
Implement the following in the .NET Console App. Write the Bus class. A Bus has a length, a color, and a number of wheels. a. Implement data fields using auto-implemented Properies b. Include 3 constructors: default, the one that receives the Bus length, color and a number of wheels as input (utilize the Properties) and the Constructor that takes the Bus number (an integer) as input.

In Java: -Using a BST Interface (Binary Search Tree) -Create a class Disk. Disk contains four fields: model (String), size (int), measure (String, for GB or TB), and performance index (int). -Disk needs a constructor to initialize all fields, a toString method, and an equals. Make the class Comparable and write a compareTo method that compares Disks based on the size of the disk. Make sure your comparison accounts for the fact that some numbers are in GB and some are in TB. Write a method that will return true if the disk is the same size as the parms; parms are the size and measure("GB" or "TB"). Also write a method to create a Comparator which compares Disks based on the performance rating. -The client code should do the following: Write a function called build, which will open the disks.txt file, read in each disk and add it to the BST. For each disk the model is on the first line, and the second line contains the size, measure, and performance index. The BST is passed to build as…
write in javascript please A cryptid is a legendary creature that, if it exists, is an animal rather than a monster or supernatural entity. For example, yetis, bigfoot, and chupacabras are all cryptids. Use Prototype inheritance to create a cryptid object and a derived bigfoot object. The Cryptid should have a name, a height, and an attack method that prints something like "Bob the generic cryptid, 7 feet tall, attacks with its special weapon!". The bigfoot should *also* have a shoe size, and its attack should print a message like "Barry the bigfoot, 8 feet tall, stomps you !" Write code to demonstrate that your prototypes are correct. You do not need to take user input. write in javascript please
