import java.io.*;
import java.util.Scanner;
public class FiOutputGetChannel1 {
public static void main(String[] args) {
        // TODO Auto-generated method stub
        File file= null;
        FileInputStream fin=null;
        FileOutputStream fout=null;
        Scanner sc;
        try {
            //creating a txt file.
            file= new File("./JavaTpoint.txt");
            file.createNewFile();
            System.out.println("Enter a string to get the file channel------>");
            sc= new Scanner (System.in);
            //taking a string from the user  and convert it into char Array
           char[] s= sc.nextLine().toCharArray();
            // write a string into the txt file.
            fout= new FileOutputStream(file);
            for(int i=0; i<s.length;i++)
            {
                fout.write(s[i]);
            }
            // reading a data from the txt file
             fin= new FileInputStream(file);
             int read ;
             System.out.print("String that is stored in the JavaTpoint Txt file ------>");
             while((read=fin.read())!=-1)
             {
                 System.out.print((char)read);
             }
          // returns file channel associated with this stream
              System.out.println();
              System.out.println();
              System.out.print("file channel associated with this stream is----->"+fout.getChannel());
             //releases FileOutputStream resources from the streams
               fout.close();    
             fin.close();
            }
        catch(Exception e)
        {
        System.out.println(e);    
        }}}

Output:

Enter a string to get the file channel------>
ashu
String that is stored in the JavaTpoint Txt file ------>ashu

file channel associated with this stream is----->sun.nio.ch.FileChannelImpl@30c7da1e
