Java Source Coded to read and write into a file character by character

The following source code is an example of how to read and write the content of a file character-by-character to another file. This is also an example of how to give the file name as an input at the command prompt :


import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Scanner;

public class ReadWrite {

public static void main(String[] args)throws IOException {
FileReader fileInput = null;
        FileWriter fileOutput = null;
        Scanner input;
        try
        {
        System.out.println("Enter the File Name with Location");
        input=new Scanner(System.in);
        String filePath=input.nextLine();
        fileInput = new FileReader(filePath);
            fileOutput = new FileWriter("C:\\Untitled1.txt");
            int character;
            while ((character = fileInput.read()) != -1) {
                fileOutput.write(character);
            }
        }
        catch (IOException e)
        {
            System.out.println("Error message: " + e.getMessage());
        }  
        finally
        {
           
            if (fileInput != null)
            fileInput.close();        
            if (fileInput != null)
            fileOutput.close();    
       }
  }
}
