Create a class named “Car” which has the following fields. The fields correspond to the columns in the text file except the last one. i. Vehicle_Name : String ii. Engine_Number : String iii. Vehicle_Price : double iv. Profit : double v. Total_Price : double (Total_Price = Vehicle_Price + Vehicle_Price* Profit/100) 2. Write a Java program to read the content of the text file. Each row has the attributes of one Car Object (except Total_Price). 3. After reading the instances of a Car, “Total_Price” will be calculate, and then the object must be saved in an array of objects. 4. Write each object created to a seperate file, for example: "Honda.txt", “KIA.text” and “BMW.text” for the following sample input file. 5. Write a method named showCar(double eNumber),takes the Engine Number as parameter, and displays all the information of the particular car including Total Price. Sample Input File: Honda 33244231 80 5 KIA 5544546 60 4 BMW 9846343 110 3.5
