- This is for Advanced Java Programming Write a test program that reads words from a text file and displays all non-duplicate words in ascending order and then in descending order. - The file is to be referenced in the program, not needing to be used as a command line reference. - The word file is to be titled collection_of_words.txt and included in your submission. Write test code that ensures the code functions correctly.Linux commands: In this part of the lab, you will run Linux commands, capture their output in a format that shows the command and its results in an easy way (command-> new line-> output - > new line-> new line-> command, .... etc). In your output file, make sure to print out the name of your user account and todays date. It should look something like this "My Student Account is " , "Todays Date is ". Can someone please help with this ?Use Linux executable objectCode5 for this question. These files are on syccuxas01.pcc.edu in directory ~michael.trigoboff/cs201/quiz02LinuxFiles. The file is run from the Linux command line, and takes one positive numerical argument, like this: ./objectCode5 3 (You can enter any small positive integer instead of 3.) Command line arguments are passed to int main(int argc, char** argv) as arguments argc and argv. You should assume that argc is at ebp+8 and argv is at ebp+12. This code contains a function named what. Using gdb, figure out what the function named what computes: Question options: 1) the absolute value of n 2) n squared 3) the sum of the integers from 1 through n 4) factorial of n

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. Input file Phillips,1237DF2,100,1200 Phillips,546AHH7,75,900 Phillips,875RTM6,4,750 Cree,14573,65,800 Cree,86545,100,1100…In Chapter 11, you created the most recent version of the MarshallsRevenue program, which prompts the user for customer data for scheduled mural painting. Now, save all the entered data to a file that is closed when data entry is complete and then reopened and read in, allowing the user to view lists of customer orders for mural types.
- You will develop a client side and a Servlet program that will work with a database. 1. The client (front end) should have a title "NJIT Credit Union", centered. 2. The client should have a background color. 3. The client should have a text field with label 'UserID' where user will enter userID (integer) and a Submit button with text "Submit". 4. An unsuccessful authentication should have a message printed on the screen, in red, stating that "Your authentication has failed, please try again.” (no pop up message). At this point the text field should get cleared and ready to accept a new input. Your program should not exit. 5. A successful authentication should be followed by a message on the screen, in green, stating that "Your authentication is successful" (no pop up message). 6. There should be two other text boxes with label "Deposit" and "Withdraw" where user will enter an amount (you should accommodate for decimals). These two text boxes should only be enabled after successful…Add a command to this chapter’s case study program that allows the user to view the contents of a file in the current working directory. When the command is selected, the program should display a list of filenames and a prompt for the name of the file to be viewed. Be sure to include error recovery in the program. If the user enters a filename that does not exist they should be prompted to enter a filename that does exist.A tar file named "male.tar" has several files. One of the files in the archive is "lonnie.yml". Writethe command that will extract ONLY the file named "lonnie.yml". The command CANNOT contain/usefilter commands such as "grep", "sed", etc. The tar file is in the directory /red/white/blue/. Yourcurrent directory is /root
- UNIX ASSIGNMENT - IXQuestion 8 : Rename all the files within a folder with suffix “CS_” i.e. suppose a folder has two files file_a.txt and file_b.pdf than they both should be renamed from a single command to CS_a.txt and CS_b.pdfFormat of file called deltafleet.txt aircraftName regnum manufacturer maxSize crewSize yearPutInService maxServiceWeight numPassengers currentAirMiles lastMaintenanceDate lastMaintenanceMiles What would be best way to read from a file using file and Scanner with try-catch block. I also have to write and append to a file called newfleet.txt. what would be best way of doing that In Java with traditional for Loops that a beginner programmer would use.UNIX ASSIGNMENT - IXQuestion 3 : Suppose you have a C project in a folder called “project”, it contains .c and .h files, it also contains some other .txt files and .pdf files. Write a Linux command that will count the number of lines of your text files. That means total line count of every file. (remember you have to count the lines in .txt files only)
