in java language 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. keep everything in one class and andinclude the method that processes the file as a static method.

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
Open the Palace Solution.sln file contained in the VB2017\Chap10\Palace Solution folder. Use Windows to copy the Rectangle.vb file from the VB2017\Chap10 folder to the Palace Project folder. Then, use the Add Existing Item option on the Project menu to add the file to the project. Modify the Rectangle class to use Double variables rather than Integer variables. Change the name of the GetArea method to GetAreaSqFt. Add another method to the class. Use Get AreaSqYds as the method’s name. The method should calculate and return the area of a rectangle in square yards. The application’s Calculate button should calculate and display the number of square yards of carpeting needed to carpet a rectangular floor. Code the btnCalc_Click procedure. Display the number of yards with one decimal place. Save the solution and then start and test the application.
I would like to open a data file in Java for Exercise 6 in Chapter 4 of JAVA by Gaddis & Muganda. The file properties shows in Explorer the location as C: \Users\Vladi\Desktop. The Files is Exercise0406.txt. I inserted the lineFile file = new File(“C:\Users\Vladi\Desktop\Exercise0406.txt”);I get Exception cannot find file.
Write a class to represent a real-world concept.•Write voidmethods and methods that return values.•Write methods that have parameters.•Implement information hiding using private instance variables, accessors, and mutators. 3.Modify the Java Class template:(a)In the Toolsmenu, select Templates.(b)In the dialog box that comes up, open the Javafolder, select Java Classand click the Open in Editorbutton.(c)A new file should open up containing the following text:<#assign licenseFirst = "/*"><#assign licensePrefix = " * "><#assign licenseLast = " */"><#include"${project.licensePath}"><#if package?? && package != "">package ${package};</#if>/**** @author ${user}*/ public class ${name} {}(d)Delete the first four lines and after @authorreplace the text ${user}with your first and last name. The file should now look like this (except with your name):<#assign licenseFirst = "/*"><#assign licensePrefix = " * "><#assign licenseLast = "…
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…

Hey, this is my code below and I cannot seem to get the import.java.io.*; to create and save information on a txt file. Any help would be great. There is a person class with get and set for firstname, lastname, etc. However I could not fit it in due to space. Code in bold is what I tried for the txt. import java.io.FileNotFoundException;import java.io.PrintWriter;import java.util.ArrayList;import java.util.Scanner; import mainInterface.Interface; public class StaffManager { protected static ArrayList<Staff> Staffs = new ArrayList<Staff>(); public static void main(String[] args) throws FileNotFoundException{ staffManMenu(); //Call writeToFile writeToFile(); } // method to write the staff data to a file titled StaffFile.txt public static void writeToFile() throws FileNotFoundException{ //create object PrintWriter write = new PrintWriter(new File("StaffData.txt")); for(Staff s : Staffs) { write.println("First Name: "…
Hi l would appreciate the help of this project in java . Part 1 The zip file my_zoo_p1.zip is on BB under the Resit folder in Programming 2. The file contains two Java classes, MyZoo and Animal, and two text files import001.txt and import002.txt containing "animal" data. Download these into your filespace. Although the MyZoo and Animal classes are similar to the classes in the original Zoo project, there are some important differences. For example, the Animal objects in the zoo are stored in a TreeMap rather than an ArrayList. Animals are added to the TreeMap using the put() method which requires a unique key value to be specified (similar to the HashMap discussed in Chapter 6). You can examine the documentation for TreeMap if you wish, but no detailed knowledge of this class is required for this project. Another difference is that the MyZoo class has a three letter identifier, provided to the constructor, and a method allocateId() for creating unique identifiers for animals…
You must now write a method readVehicleData() in the ReservationSystem class, that reads this data, creates corresponding Vehicle objects and adds those objects to vehicleList. The name of the file that you read from should be selected using a file dialog box -- the name should not be passed to readVehicleData() as a parameter.
You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date date, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email provide getters/setters, constructors, toString. Provide following options to the user. Add Friend (which add new friend to the Friends file) View Friends (read data from Friends file and display) Send message (This should ask for friend name and message match the friend name and write that message to the inbox file). Read messages (This show all messages form inbox on JList or Text area. Note: Create a manager class with methods use to read and write messages to “inbox” file you should write sentMessage(Friend f, Message message) method which write the messages to the file user can send as many message as he/she wants (use loop and arraylist). Write another method readMessages()…
