Write a java program that would ask the user to enter an input file name, and an output file name. Then the program reads the content of the input file, and then writes the content of the input file to the output file with each line proceeded with a line number followed by a colon. The line numbering should start at 1. should be used the following technique (a) while loop should be used to complete the program. (b)Scanner classisused (c) PrintWriter class is used (d) The files are closed before the program terminates. ExampleOriginal Input fileOutput file with line number added1341: 1341252: 1251123: 1121894: 189 Solution FileCopier.java:- import java.io.File; import java.io.FileInputStream; import java.io.FileWriter; import java.io.IOException; import java.io.PrintWriter; import java.util.Scanner; public class FileCopier { public static void main(String[] args) throws IOException{ Scanner in=new Scanner(System.in); System.out.println(\"Enter input file\"); File inputFile=new File(in.nextLine()); if(!inputFile.exists()){ System.out.println(\"Source file doesn\'t exist\"); System.exit(0); } FileInputStream fis=new FileInputStream(inputFile); System.out.println(\"Enter output file\"); FileWriter fw=new FileWriter(in.nextLine()); PrintWriter pw=new PrintWriter(fw); in=new Scanner(inputFile); int i=1; while(in.hasNextLine()){ String s=in.nextLine(); pw.write(i++ + \": \" + s + \"\ \"); } pw.flush();pw.close(); } } Console output: Enter input file test.txt Enter output file output.txt Sample run 1:- test.txt: hey 123 . howdy output.txt: 1: hey 2: 123 3: . 4: howdy Sample run 2:- test.txt: 123 345 567 789 output.txt 1: 123 2: 345 3: 567 4: 789.
