Write a shell script that reads a file name and checks this file exists or not. If the file exists, searches this file for "Joshua" or "joshua" and displays the total number of occurrences of "Joshua" and "joshua"; if the file does not exists, display "the file does not exist." Hints: you can use cat and egrep.

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…
Create a list of 5 words, phrases and company names commonly found in phishing messages. Assign a point value to each based on your estimate of its likelihood to be in a phishing message (e.g., one point if it's something likely, two points if modereratly, or three points if highly likely). Write an application that scans a file of text for these terms and phrases. For each occurance of a keyword or phrase within the text file, add the assigned point value to the total points for the number of occurences and the point total. Show the point total for the entire message. (Write the program in Java)
Use the Bash shell for the completion of this project. Develop a shell scripting application that allows the user to perform some advanced mathematical operations: Task 1: Find the even multiples of any number chosen by the user in a given range – the user should specify the multiples of which number they want to print and a minimum and maximum value. The multiples printed should be within the [minimum, maximum] range. For example, if the user choses the number 7 and would like to print all even multiples in the [15, 60] range, the program should print all the even multiples that are bigger than or equal to 15 (minimum), but smaller than or equal to 60 (maximum). The program should keep a count of how many numbers were printed and should output that count, as well as the numbers. The output then, for theexample given, should be 28, 42, 56, and the count should be 3.
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.
Write a program that will read the file text.txt which is provided and the encryptedmessage in there. Please write back the decrypted message into the output.txt file.When you see the message in the output.txt file, you need to submit the java codefile. You need to use Rot13 class for decrypting the message. Do not need to submit in the output.txt file. file example: public class FileExample { public static void main(String[]args){ try {//create file object for input.txtFile in_file = new File("src/input.txt");//create file object for output.txtFile out_file = new File("src/output.txt"); //read the input.txt file with ScannerScanner read = new Scanner(in_file);//write the output.txt file with PrintWriterPrintWriter w = new PrintWriter(out_file); while(read.hasNextLine()){w.write(read.nextLine());} //don't forget to closew.close(); // while(scan.hasNext()){// System.out.println(scan.next());// } }catch(Exception ex){ex.getStackTrace();}
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…
Java OOP Write a complete address book maintenance application. The user of the program has four options: Add a new person, delete a person, modify the data of a person, and search for a person by giving the name. Use the AddressBook class, either the original one from the chapter or the modified one from the previous exercises. You have to decide how to allow the user to enter the values for a new person, display person information, and so forth.

Write an application that throws and catches an ArithmeticException when you attempt to take the square root of a negative value. Prompt the user for an input value and try the Math.sqrt() method on it. The application either displays the square root or catches the thrown Exception and displays an appropriate message. Use Java programming language.

Rules: Corner cases. Throw the specified exception for the following corner cases: Throw an IllegalArgumentException if the client calls either addFirst() or addLast() with a null argument. Throw a java.util.NoSuchElementException if the client calls either removeFirst() or removeLast when the deque is empty. Throw a java.util.NoSuchElementException if the client calls the next() method in the iterator when there are no more items to return. Unit testing. Your main() method must call directly every public constructor and method to help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. Your implementation must achieve the following worst-case performance requirements: A deque containing n items must use at most 48n + 192 bytes of memory, not including the memory for the items themselves. Each deque operation (including construction) must take constant time. Each iterator operation (including construction) must take…
