You will write a method that will take a file name (String) as a parameter that is a file of numbers and will return the sum of the numbers in the file. You will then create a GUI with the following: 1. Some way for the user to specify a file name. 2. A mechanism for the user to begin processing the file. 3. Some place to display the sum of the numbers. You can keep everything in one class and just include the method that processes the file as a static method.
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
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.

Write another Java class named Patient that contains: ■ A private integer data field called id. ■ A private static integer data field called numberOfPatients that counts the number of Patient objects created (default value 0). ■ A private String data field called name. ■ A private Address variable called address. ■ A private File variable called file that refers to a database.txt file. ■ A constructor that creates a patient object with specified name and address. Note that the id of patients is auto-incremented. If 3 patients are created the first one would have id 1, the second id would be 2 and the third id 3. ■ A static method getNumberOfPatients() that returns the number of patients. ■ A method getId() that returns the patient’s id. ■ A toString() method that returns a one-line description of the patient. ■ A savePatientToFile() method that is called every time a new patient object is created to save the patient information (patient object) to the database file.
In a Java program, create an automobile class that will be used by a dealership as a vehicle inventory program. The following attributes should be present in your automobile class: private string make, private string model, private string color, private int year, private int mileage. Your program should have appropriate methods such as: constructor, add a new vehicle, remove a vehicle, update vehicle attributes. At the end of your program, it should allow the user to output all vehicle inventory to a text file.
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 {…
please use java to answer the following question Implement a program with a GUI and Action listener that looks like the one shown below You should connect to the database ( make sure you have maximum 5 rows in your table) The table should contain of the name, card number and the pin number of the customers who uses the ATM once you enter the card number and the pin number that exist in the database, then by clicking on the Login button, you could show a dialogue dialog box in which it shows the name of the customer and then indicates that that name is login successfully ( Mehrnaz is login successfully). Otherwise, the dialogue box indicates that the information does not exist in the database. The clear button will clear all the information on the GUI.
For this exercise, you will create 2 classes: InputOutput class and AddNumbers class. ⦁ InputOutput Class: write a program that carries out the following tasks:⦁ Create an object of type PrintWriter and that writes into a file with the name greeting.txt.⦁ Print the message “Hello, world!” on the file.⦁ Close the file.⦁ Open the same file again.⦁ Read the message into a string variable (hint: use nextLine() method to read the text).⦁ Print the message on the screen. ⦁ AddNumbers Class: write a program that asks the user to input four floating-point numbers. Add all correctly specified values and print the sum when the user is done entering data. Use exception handling to detect improper inputs. For example, the user might enter letters instead of numbers. In this case, use the exception handling mechanism to print a proper message. (hint: use InputMismatchException) Don’t forget to import java.util.*.
** in JAVA ** Write a Java program called ThreeWords that prompts (asks) the userto enter three words, separated by a space, on the same line and readin using the .nextLine( ) method of the Scanner class. You may NOTuse the .next( ) method of the Scanner class in this Task. Using the .next( ) method of the Scanner class will result in this Task being awarded 0, regardless of correct execution.(You may assume that the user always enters 3 words, each word separated by a single space.)Once the user has entered the three words, the program displays to the screen the longest word, that is, the word with the most characters. In the event of one or more of the words having the same number of characters, the program may decide which word it displays to the screen.
In Java. Write a complete static method named favoriteWords that accepts, in order, an Scanner170 object and a one letter long String. The method repeatedly prompts the user to enter words (using the Scanner170 object) until two consecutive words starting or ending with the letter passed in the second parameter are entered. The method begins with a simple description to the user and ends with a printout of the two words that matched (two in a row starting or ending with letter). Begin by writing complete pseudo code for your algorithm.
Given main(), define the Artist class (in file Artist.java) with constructors to initialize an artist's information, get methods, and a printInfo() method. The default constructor should initialize the artist's name to "unknown" and the years of birth and death to -1. printInfo() displays "Artist:", then a space, then the artist's name, then another space, then the birth and death dates in one of three formats: (XXXX to YYYY) if both the birth and death years are nonnegative (XXXX to present) if the birth year is nonnegative and the death year is negative (unknown) otherwise Define the Artwork class (in file Artwork.java) with constructors to initialize an artwork's information, get methods, and a printInfo() method. The default constructor should initialize the title to "unknown", the year created to -1. printInfo() displays an artist's information by calling the printInfo() method in Artist.java, followed by the artwork's title and the year created. Declare a private field of type…
