***JAVA***

You will design a program that reads and writes to a file.

The specifications are:

There will be a text file that your program will read.

There will be a second text file that your program will write to.

The textfile can be a file you created, or a text file you found on the internet. Your choice. There must be two separate textfiles.

As a hint, here is a textfile you can use - file named names.txt with line(1) Smith, Bob (2) Johnson, Brady (3) Brody, Jessica (4) Hanson, Martin

Another hint....the textfile should be in the same directory as the program.

public class ReadWriteFileDemo {
  
   public static void main(String[] args) throws IOException {
      
       Scanner sc = new Scanner(System.in);
      
       //reading file names
       System.out.print("Enter input file name: ");
       String input = sc.next();
       System.out.print("Enter ouput file name: ");
       String output = sc.next();
       // opening input file
       FileReader fr = new FileReader(input);
       BufferedReader br = new BufferedReader(fr);
      
       // opening output file
       FileWriter fw = new FileWriter(output);
       BufferedWriter bw = new BufferedWriter(fw);
      
       String line;
      
       // reading line by line and stroing into output file
       while((line = br.readLine()) != null){
           bw.write(line);
           bw.newLine();
       }
      
       //closing files
       bw.close();br.close();fr.close();fw.close();
   }
