Explain more of the given sample below: Log4j is a java library that developers use to record activity within the application. The hacker needs to exploit the flaw to send malicious data/code string and eventually log by the Log4j java lib, enabling access for hackers through the system.   I'm not sure what my prof wants but I think a brief info is what he wanted?

I NEED BulbGUI.java Using JAVA, Create a File Menu in your GUI Add a file menu to your BulbGUI with options to open any file for reading (and displaying the file as in Project 2), and one to Quit the program. You will need a FileMenuHandler class to handle the events from the FileMenu. Be sure to use getAbsolutePath() when getting the file from the JFileChooser, not getName(). Handle Exceptions Create an exception called IllegalBulbException (by extending IlegalArgumentException as shown in the lecture) and have the constructor of the Bulb throw it. For our purposes, a Bulb is illegal if the wattage is less than 5. Use a try/catch statement to catch this exception in your program, and display the erroneous Bulbs to the console (do not put them in the ArrayList). Use ArrayLists Use an ArrayList to store the unsorted Bulbs. For this project, display only the unsorted bulbs in the GUI.

Our users do not want to have to re-enter the price levels each time the app starts. Therefore,  we need to save the price levels to a file on disk – called levelsFile - and populate the levelsList with the file’s items when the app starts. Also, every time the user manipulates the values in levelsList, levelsFile needs to be updated accordingly. The easiest way is not to update the file, but to simply override it (create a new file) with the new values in levelsList (each time the user manipulates items in the list). Two new methods need to be created in the PriceChecker class. They are readLevelsFromFile() and writeLevelsToFile(). And then the Main Code Section must also be updated to use these methods in the object. Note: The changes required to the Main Code Section are supplied on the next slide, but you need to complete the skeleton code of the two newly mentioned methods (supplied on subsequent slides).

Note that even though you know the name of the input file, you should not hard-code this name into your program. Instead, prompt the user for the name of the input file.The input file should contain (in order): the weight (a number greater than zero and less than or equal to 1), the number, n, of lowest numbers to drop, and the numbers to be averaged after dropping the lowest n values.You should also prompt the user for the name of the output file, and then print your results to an output file with the name that the user specified.Your…

My question has to do with Java programing. I am attempting to do a Regex Lab and read in a text file and validate whether or not it is license plate. The problem is that the text file is read and one of the examples is "ABC 1234", but it reads "ABC" instead of the whole line. I will attach the screenshots of what I have so far.

Despite the fact that I have created a separate main class file, the NetBeans IDE says that there are no main classes when I run my Java code. What's going on? Please let me know. What should I do to get it fixed?

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "Rooter" (without the quotation marks) to get a positive integer (i.e. any number greater than 0) called "start" from the user at the command line and then find the square root of every number from "start" down through 0. Use a while loop to count down. As an example, if the user entered 8, you would find the square root of 8, then the square root of 7, and so on. Print each square root on a separate line. Include data validation to ensure the user provides a positive integer. If the validation is not passed, provide the user with suitable feedback and stay in the program to let the user try again until valid input is received. Use the Math.sqrt(double a) method to find each square root and output the integer and four decimal positions. You do not need to use the scanner hasNextInt() method. to validate the…

Your company is doing some data cleanup, and notices that the email list of all users has been getting outdated. For one, there are some users with repeat email addresses, and some of the email accounts no longer exist. Your job is to create a series of methods that can purge some of the old data from the existing email list. Create static methods in the DataPurge class that can do the following: removeDuplicates This method takes an email list, and removes the duplicate email values. It also prints to the console which duplicate emails have been removed. removeAOL This method removes all email addresses from a list that are from aol.com. It notifies the user which email addresses are being removed as well. containsOnlyEmails This method returns true if all of the data in the email list is actually an email address. We will define something as an email address if it contains the characters @ and . Test your methods out in the DataPurgeTester file. You don’t have to change anything…

This is sample data from my JSON file: "firstName" : "Juan","middleName" : "Dela""lastName" : "Cruz","username" : "JuanDelaCruz","password" : "1234", I already have a JAVA GUI that displays the data of each user in a table format. I need the part of my program that will allow the server to either accept or reject the user. If the user is accepted, the credentials of the user will be saved in another JSON file. If rejected, the server will do nothing.

Reverse The VerseJUnit: P2J3Test.javaOne last batch of transitional problems adapted from the instructor's collection of Python gradedlabs. Only three methods to write this time, though. The JUnit test for these labs uses thewarandpeace.txt text file as source of data, so please ensure that this text file has been properlycopied into your course labs project folder. This text file, same as any other data files you woulduse, does not show up anywhere in the BlueJ project screen, even though it is part of theproject directory that contains the Java source code for the solutions and the unit tests.public static void reverseAscendingSubarrays(int[] items)Rearrange the elements of the given array of integers in place (that is, do not create and return anew array) so that the elements of every maximal strictly ascending subarray are reversed.

Demonstrate how the Path class works and test the file's accessibility. This lab builds upon lab 1, so all you will need to do is update the code. Type up the code, execute the program and submit the output only. You will have to provide an absolute path for the program to work.

In a UP project, each iteration ends with a stable executable. Select one: a.FALSE b.TRUE

The payloads used in this lab were not sophisticated at all and would likely raise some red flags. The msfvenom tool provides a method of putting the payload in an existing executable. For testing, another member of your team has created a simple program that displays a success dialog and will open a simple text file if the user chooses Yes. The program is /home/kali/payload.exe on AttackLinux01. Research the options for the command line use of msfvenom and determine how to create a payload that uses windows/meterpreter/reverse_tcp inside this test program.

please follow the screenshot as a reference which is posted.  can you make it so it reads from the kongcrew.txt file instead of typing out the info? can you also make where it lists all of the specifications with the information below like the bolded text in the picture? example below Name       Sit      Walk        Swing ....... and so on with the info below (make one print  out before adding the second ss and after so it shows the updated info of how many bananas the monkeys have before and after) instructions in the picture, KongCrew.txt file with the info below.
