We will use the file classlist.txt. Note that it contains a list of usernames. 3. Write a script called finduser that is to be called as follows, where classlist is the name of the classlist file, and username is a particular student's username, either first name or last time. ./finduser classlist username The script should check that the correct number of arguments was received and print an error message if not, check whether the classlist file exists and print an error message if not, print the line of the given username in the classlist file If you have not been doing so all along, you should now add some comments to your script and thoroughly test it! 4. Write the script into your lab report.
Modify the SalesReport2.java program to use the BadData.txt file. You will input integers from this file and continue on if there is a bad record. If a record is bad (nonnumeric), display the file name. Do not just put the filename in quotes, display what file the program used. Change what displays in the catch statements. Add a finally clause. Do something in this clause. See when it is run. Remember: in Eclipse a file must be added to the project, not the src folder. Naming: Name the Java project: LastFProjectAssign09 Name the driver program (main): LastFAssign09.java Where Last is your last name and F is the first initial of your first name. Ex: OgleD Save in a file folder on your storage device SALESREPORT2.JAVA PROGRAM BELOW import java.io.*; // For File class and FileNotFoundExceptionimport java.util.*; // For Scanner and InputMismatchException /** * This program demonstrates how exception handlers can * be used to recover from errors. */public class SalesReport2{public…
In this lab, you will read two files. Firstly, the ‘AccountData.csv’ file has the name and account number.Use each account number to scan the ‘BankData.csv’ file for a matching account number to get a ‘balance’from the account transactions. You must repeatedly open, read the ‘BankData.csv’ file and close it for eachaccount number in the ‘AccountData.csv’ file unless you wish to store its entire contents in a static array.(More code and may not be enough time to complete.) import java.io.*;import java.nio.file.Files;import java.nio.file.Path;import java.nio.file.Paths;import java.util.ArrayList;import java.time.format.DateTimeFormatter; public class BankDataProcessing { static DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MM-dd-yyyy HH:mm"); static ArrayList<BankAccount> Accounts = new ArrayList<>(); public static void main(String[] args) { try { Path path = Paths.get("src/AccountData.csv"); readAccounts(path, true);…
Please make a procedure that takes two parameters and prints a list of students from the first parameter as a student ID to the last parameter which is another student ID. If student is not found, then process an exception NO_DATA_FOUND.
The history teacher at your school needs help in grading a True/False test. The students’ IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form:TFFTFFTTTTFFTFTFTFTTEvery other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry:ABC54301 TFTFTFTT TFTFTFFTTFTindicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9. The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score, followed by the test grade. Assume the following grade scale:90%–100%, A; 80%–89.99%, B; 70%–79.99%, C; 60%–69.99%, D; and…
Implement a ROT13 simple replacement cipher as described in this article. You can limit your transformation to just the upper and lowercase letters (i.e., you do not have to transform punctuation or spaces). Requirements Similar to the earlier parts of this assignment, use the provided template file p4 3.py I to implement the encrypt and decrypt functions. Use the tests provided in CodingRooms to verify your solution. Hint: You may wish to use the Python string maketrans function, but it's not required - as long as you correctly handle all uppercase and lowercase letters. Example doctests output: python -m doctest p4_3.py -v Trying: decrypt('Qb be qb abg. Gurer vf ab gel.') Expecting: 'Do or do not. There is no try.' ok Trying: decrypt('Nubl, gurer!') Expecting: 'Ahoy, there!' ok Trying: encrypt('Do or do not. There is no try.') Expecting: "Qb be qb abg. Gurer vf ab gel.' ok Trying: encrypt('Ahoy, there!') Expecting: 'Nubi, gurer!' ok 3 items had no tests: p4_3 p4_3. get_rot13 p4_3.…
Create a program for caesar cipher in which the user enters a string of lowercase alphabets and the shift. The program should display the encoded string in the output. You can use the programming language of your choice but add the output screenshot in the file and test your code for the test case "fzyxtnavhal".
Consider the data contained in the text file data1.txt. The first row of this file contains the column names. The remaining rows have one number for each column. The numbers are separated by a tab character. You can work in your command window. No need to create a matlab file for this question. Download the data file. Use importdata() function to load data into Matlab. What is the average of the numbers contained in the third column of this data? Data1: col1 col2 col3 col4 col5 906 552 743 348 45 676 229 425 661 558 469 642 430 384 773 913 485 125 628 312 105 152 25 22 179 746 782 291 911 339 737 101 318 801 211 562 295 654 746 511 185 238 957 814 907 598 531 936 384 629 300 92 458 618 102 135 406 241 576 391 213 105 764 531 55 895 113 760 276 502 72 785 741 249 432 243 292 744 452 998 54 604 106 228 812 442 965 682 805 486 14 433 464 987 895 898 695 213 30 138 197 759 99 536 391 94 433 824 88 928 308 656 176 803 918 457 110 164 990 714 102 934 666 67 619 996 188 895 940 344 333 267…
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.
ScenarioI want to create an INDEXCEPTION value of the unique vowels and unique consonants that the name that was given to you can create.InputA string of the name that was GIVEN TO YOU. CASE SENSITIVE.ProcessStep 1: For every unique vowel of a name, you need to get the first index of that vowel from the original string.Step 2: For each vowel index you get from step 1, you will get the unique consonant from that position. if the index is out of scope of the consonant array, ignore that vowel index.Step 3: For each unique consonant that you get from step 2, you need to get the first index of that consonant from the original string.Step 4: Get the value of indexception by adding all index you get from step 3.OutputTO BE DISPLAYED- 2 lists that consists of unique vowels and unique consonants- The vowel, the vowel index, the consonant, the consonant indexFINAL OUTPUT- The total indexception value of the name that was given to you.
Write a program that generates student records in a database file. Your program should be able to generate at least 10 records. The format in the database should be: student name, student id The first student id should be 20180001, second id will be 20180001 and so forth. Show screenshot of script
Write a script studhts that will first attempt to open the file 'studhts.dat' created in Q-3. If the file open is not successful, an error message should be printed. If it is successful, the script will read the data into strings, one line at a time. Print for each person the name in the form 'last, first followed by the height. Also, calculate and print the number of students having heights less than 160. Finally, print whether or not the file close was successful. For example, the result of running the script would look like this: Shukla, Anubhav 143.5 Jindal, Ram 156.9 Singh, Saurav Number of students having heights less than File closed successfully. 175
