Java simple way to input the output image files

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

public  class FileR_W {
     public  static  void main (String [] args) throws IOException {
         // Create the input stream output stream 
        the FileInputStream FIS = new new the FileInputStream ( "70.jpg" );
        FileOutputStream fos = new FileOutputStream("test_jpg.jpg",true);
        int len;
        byte[] b = new byte[1024];
        while ((len=fis.read(b))!=-1){
           fos.write(b,0,len);

        }
        fos.close();
        fis.close();
    }
