- Write a script that opens a file containing a list of passwords and checks to see if the passwords are strong. 1. Save a list of five passwords in a text file. 2. Write a Python script that opens the text file and reads the passwords. 3. For each password, use regular expressions to check the password strength (I recommend creating a module to do this). For a password to be considered strong, it must satisfy the following requirements: + minimum length 8 characters + must contain one or more alphabetical characters [a-z] + must contain one or more Uppercase characters [A-Z] + must contain one or more numeric characters [0-9] + must contain one or more special characters [_$!]In this assignment, you will create a Java program to read undergraduate and graduate students from an input file, sort them, and write them to an output file. This assignment is a follow up of assignment 5. Like assignment 5, your program will read from an input file and write to an output file. The input file name and the output file name are passed in as the first and second arguments at command line, respectively. Unlike assignment 5, the Student objects are sorted before they are written to the output file. • The program must implement a main class, three student classes (Student, UndergradStudent, GradStudent), and a Comparator class called StudentIDComparator. • The StudentIDComparator class must implement the java.util.Comparator interface, and override the compare() method. Since the Comparator interface is a generic interface, you must specify Student as the type parameter when defining the StudentIDComparator class, i.e., public class StudentIDComparator implements…Create a simple java program that reads all the content in a .txt file, the user will enter the filename to be opened. In this case, the file will contain multiple lines of student details with each line containing a single student detail. Your task is to then create a student class that models the firstname, lastname, year of birth and gender of every student. The student class should further be able to assign every student created with a student number using a class variable[format is 2022000X, X is a number such as 1,2..] and be able to calculate the age of each student. Within the driver class add all the students read from file into an ArrayList and then print the first and last student in the list. You are additionally expected to deal with most common exceptions
- In C write a program that takes a file name and two strings as command line arguments, and writes the longer of the two strings to the file with the given name. If the given strings are the same length, write the first string given to the file. If the user does not provide the correct number of command line arguments, print an error message and exit the program with a non-zero exit code.hello, I have errors in my code, and i'm not sure on how fix my some of my myethods. I have the outline for my code bellow, as well as the rubric: description: Write a java application that will open an input file and open an output file. The file names can be entered fromthe command line, if a command line parameter is included, it will be used as the input file name. If a second command line parameter is included, it will be used as the output file name. Any missing parameters will beprompted for and read by the program. When the input file does not exist the user will be prompted to re-enteran input file name. When nothing is entered for the input file name, on a prompt, the program will proceed tothe end of the program and terminate. When the output file exists the user will havea choice of entering a new output file name, backing up the existing output file first, overwriting the existingoutput file, or quitting the program without opening any files. Again, not entering a file…IN JAVA Arrange the data for your chart in a text file as follows: The first line of the file is the title for the chart The second line of the file is the units used in the chart The rest of the file contains data values for the chart alternating with the label to print with the value on the preceding line. The program must be able to produce a chart from any data file arranged as described above. The name of the data file and the output file are provided on the command line. The program must check that there are enough command line arguments and stop with a suitable message if not. The program saves the chart to the output file (2nd command line argument); it may also display the chart to the terminal, but it is not required to. In addition to the above, accept two additional command line arguments: The maximum width for the chart (just the bar itself, not including the labels) The symbol to use for the bars
- In Java, the File class is used to represent the data in a directory entry. Write a program that uses the File class to print all the attributes of a file.Develop a program that follows the rules of Left Center Right (LCR) as described. On program start-up, it shall display the rules to the user as read from a text file submitted with the program. The user can then set up the game by entering the number of players. Any number below three shall ask the user to add more players. Once gameplay has started based on the game rules, there are a few main pieces to address.Rolling the die should be performed by randomly generating the side of the die displayed for each of the three using a random number generator. For this game, if the generated number is 1, that will be L. Additionally, 2 is R, 3 is C, and 4–6 are dots that can be represented with the asterisk symbol *. Be sure to check the current player’s number of chips before rolling. After each player’s roll, calculate the number of chips for players based on the actions dictated by the dice. Continue playing until only one player has chips. Display a message to the game winner.Left Center…with python do whis: Edit or delete a user profileWhen the user chooses 2, the first thing that it should do is to check whether the user information is loaded in the program (i.e., check if the user information is passed to the function that generates recipe recommendations). If the user information is passed to the function (i.e., the user chose option 1 before choosing option 2), the program should show the user the following menu:Hello (user name)You can perform one of the following operations:1) Delete your profile2) Edit your profilea. If the user chooses 1, perform the following subtasks to delete a user profile:1- Search for the user profile in the file userInformation.txt using the user name in read mode; once you find the user profile (i.e., the line that contains all the user information), pass it to a function that deletes the user information.2- The function should create a temporary file called temp.txt in write mode and search the file userInformation.txt in read mode…
- Unix-based operating systems usually include a tool named tail. It displays the last 10 lines of a file whose name is provided as a command line argument. Write a Java program that provides the same behavior i.e. the user can specify how many lines to print from the terminal. Display an appropriate error message if the file requested by the user does not exist, or if the command line argument is omitted. Note: Make sure to display the last n lines of a file whose name is provided as a command line argument. You might need to pass a file as an argument, therefore make sure to have access to a sample file, the contents of which you want to print out.Create a program that reads three lines from a text file. Each line should be read one at a time. For each word on a line, the user should be asked to specify how many syllables are in that word. The program should then inform the user if the file contains a valid Hiku using the function below: def isHiku (firstLine, secondLine, thirdLine):if (firstLine == 5 and secondLine == 7 and thirdLine == 5): return True return False print("The file contains a Hiku:", isHiku(5,7,5))Note: You must replace the values in the function with the numbers counted by your program.Create a simple java program that reads all the content in a .txt file, the user will enter the filename to be opened. In this case, the file will contain multiple lines of Car details with each line containing a single car detail. Your task is to then create a Car class that models the Make, Colour, type and year manufactured. The Car class should further be able to assign every car created with a unique serial number using a class variable[format is AAAYYYYCXX, AAA is the first 3 letters of the make, YYYY is the year it was manufactured, C is the first letter of the colour and XX is the value provided by the class variable(in form 01) all in upper caps see samples]. Within the driver class add all the cars read from the file onto a stack following LIFO approach and then print details of 2 cars from the stack that are older then 5 years. You are additionally expected to deal with most common exceptions(See samples below) [HINT: DO NOT PROVIDE A PATH BUT RATHER ONLY OPEN THE FILE WITH…
