note
- the operations must be stored in a txt file and make read method to read it
- The samples are separated with new-line ("\n").
please take your time I would really appreciate the help I am not in a hurry
hank you very much :)

- Assume that multiple arithmetic operations? are stored in a file. However, some of the results are wrong. Write a method that finds the operations which the results are wrong in given file. For example, given operations 1.0 + 2.0 4.0 %3D 2.5 + 2.5 5.0 %3D 3.0 / 2.0 1.0 the method should return Oth and 2nd line strings. Note: Do not round the numbers in any step of the calculation.Java Programming: Below is the shank.java file which is the main method file along with shank.txt. The main goal is to make sure to use this method: (List<String> lines = Files.readAllLines(Paths.get(filename));) to read the text file. Show the full code with the text file being read in the output. There must be no error at all. package mypack; import java.io.IOException;import java.nio.charset.Charset;import java.nio.charset.StandardCharsets;import java.nio.file.Files;import java.nio.file.Path;import java.nio.file.Paths;import java.util.List; public class Shank { public static void main(String[] args) { Path filePath = Paths.get("shank.txt"); Charset charset = StandardCharsets.UTF_8; if (args.length != 1) { System.out.println("Error: Exactly one argument is required."); System.exit(0); } String filename = args[0]; try { List<String> lines = Files.readAllLines(Paths.get(filename)); for (String line : lines) { try {…For this assignment, your program will read characters from a string for the purpose of assigning data from that string to the private data members of a class. This simulates a program that would read a record in from a stored file into memory for the purpose of making changes to that record. Below is a template of your program. For this assignment, you MUST use loops (100 pts off if not using loops) and you cannot use the following methods: indexOf() substring() subsequence().
- Computer Science Consider a look-up service for the television shows on a given date. A file contains information about these shows. Each show’s data appears on two lines. The first line gives the name of the station, the channel, the name of the show, and a rating. These entries are separated by tildes (~). The second line briefly describes the show. Write pseudocode for a method with the header public void readFile(Scanner data) to read the file into a dictionary that will be searched. Decide what data should be the search key and what should be the associated value. Design any classes needed for the key and the value. Write pseudocode for the method Do not write any code for the answer. Use UML, pseudocode, and written Description.Question 3: Write the bin2Dec(String binaryString) method to convert a binary string into a decimal number (your method should return an integer). Implement the bin2Dec method to throw a NumberFormatException if the string is not a binary string. Test your method in a program that prompts the user to input a binary string and uses your bin2Dec method to print out the decimal equivalent of that string. If the method throws an error, have your program catch it and print "Not a binary string." before terminating.Java: Write a static method named textCount that takes a Scanner representing a file as a parameter and that reports various statistics about the file. In particular, your method should report the number of lines in the file, the total number of characters (not counting any new-line \n characters) in the file, and the length and text of the longest line. You may assume that the input file has at least one line of input. For example, if the file contains the following text: Twas brillig and the slithy toves did gyre and gimble in the wabe. All mimsey were the borogroves, and the mome raths outgrabe. "Beware the Jabberwock, my son, the jaws that bite, the claws that catch, Beware the JubJub bird and shun the frumious bandersnatch." The program would find that there are 9 lines (blank lines count), a total of 254 characters in the file (33 on the first line, 32 on the next line, 31 on the next line, 28 on the next, 0 on the next, etc) and that the longest line is the one that begins…
- In JAVA, write a program in a single file that: Main: Creates 10 random doubles, all between 1 and 11, Calls a method that writes 10 random doubles to a text file, one number per line. Calls a method that reads the text file and displays all the doubles and their sum accurate to two decimal places.

You will then create and use the following methods:• A validation method that takes in the message (as a string) and the offset integerentered by the user. The method should return “true” if the offset is between 0and 26 inclusively and the message contains only letters and spaces. If it failseither criteria, it should return “false”.• If the validation method returns true, a second encryption method should becalled. This method also takes in the message (as a string) and the offset integerentered by the user. It should convert the message to UPPERCASE, encryptevery letter in the message, and leave the spaces as they were. It should thenreturn the encrypted message. i attached an image of the sample outputIn python using beginners methods (no custom classes etc) and small files - How do I have a user find and replace bad information in a text file? My instructor says: The program will READ in data from a text file named StudyHours.txt. The user corrects any bad data. The program updates the information in StudyHours.txt file. For example if the file contains a letter grade of K which is not a possible letter grade. StudyHours.txt contains the following data: first line full name second line number of credits third line grade desired for each class Example format StudyHours.txt file Aaron RODgers 12 A Tom brady 9 K philip Rivers apple c Joe Theismann 15 B I need to show the user the contents of the file, have them enter in corrections, and then update the file with the correct information with the bad information deleted.

None of these O d. public ReadWords) throws FileNotFoundException {...}Assume there is a static method called scienceTechEngrMath that takes a String parameter. Its prototype is below:public static String scienceTechEngrMath(String department) This method will return the answer to any department-based question, but… it will throw exceptions in the following cases: • NullPointerException is thrown if you pass it “null” instead of an actual department string • NotInTheDivisionException is thrown if the length of the characters in the department name is less than 7 • ThatIsInvalidDivisionException is thrown if the length of characters in the department name is more than 11 characters private static void askDepartment(String question) { try { String response = scienceTechEngrMath(question); System.out.println("1"); } catch (NullPointerException e) { System.out.println("3"); } catch (NotInTheDivisionException e) { System.out.println("5"); }…Language/Type: Related Links: Author: Java file input Scanner Nick Troccoli (on 2017/04/25) Write a method named classPresidents that tallies votes for presidents of two school classes. Somehow the vote tallies for sophomore and junior class presidents got mixed up! Your method should accept as its parameter a Scanner representing a file of vote results. It should output the next sophomore and junior class presidents. The file format looks like the following: Jared s 25 Sophie j 12 Tom j 44 Isaac s 30 Emily s 60 Russ s 23 Madison j 20 The file repeats the pattern name year votes. The year is either "s" for sophomore or "j" for junior. Your program should output the candidate in each presidential race with the most votes, and how many votes they got. Specifically, if this file were named candidates.txt, your method could be called in the following way: Scanner input new Scanner (new File("candidates.txt")); classPresidents (input); The above call should produce the following output:…
