CODE IN JAVA Please look at the attached image for the information about the format the code should be in It should have 2 java files one acting as server and other the client Design and implement an application that reads a sequence of up to 25 pairs of names and postal (zip) codes for individuals. Store the data in an object of a class called “NameAndZip”, designed to store a first name (String), last name (String), and a postal code (int). Create a driver class called “NameAndZipList”. Assume that each line of input will contain two strings followed by an integer value. You will then create an object for each line read in and store that object in an array of NameAndZip objects. After the Names and Codes have been entered, print the list in an appropriate format to the screen using the toString method in the NameAndZip class. To test the program enter 3 names and codes.

Computer Science In java design 2 classes, one where you design a Car object with 3 features, doors, windows and seats. Include one toString method that returns how much you have for each feature. This is NOT serializable, the file is .txt In the second class, create a client class, where you have an existing file, which already has 2 car objects in it, delete the second line with the car object, so there is only 1 and then write in the file 4 car objects from the Arraylist. DO NOT use colons ":" in your work . Explain all steps of your work and display an output. Don't use buffer reader or file reader. Use Scanner when reading a file, below are the imports you can use, YOU can also use any type of error message import java.io.FileWriter;import java.io.IOException;import java.io.PrintWriter; import java.util.Scanner here is a example of scanner if needed Scanner file = new Scanner( new File("flights.txt" ) );
