File i/o problem

Question

iam trying to copy file so i made class it's name filemanager and i made static method called
copy and i used the low level streames without filtering, to read and write, but i found the copy proccess it too too slow, and when i used the BufferedInputStream classes in reading and writing i found the copy proccess is fasterbut the output file is smaller than the input file by littel bytes
//this is the code for the filemanager class
//i compiled it and put it in my classes library
public class FileManager{
     static public void copy(File file1,File file2){
          try{
          FileInputStream f1=new FileInputStream(file1);
          FileOutputStream f2=new FileOutputStream(file2);
          BufferedInputStream ino=new BufferedInputStream(f1);
          BufferedOutputStream outo=new BufferedOutputStream(f2);
          boolean eof=false;
          while (! eof) {
          int c=ino.read();
          if (c==-1)
          {eof=true;}
          else{outo.write(c);}
          catch(IOException e) {
               System.out.println(e);
//and in my application i imported it used it
public static void main(String args[]) {
          System.out.println("Starting Copy...");
          File file11 = new File( "g:\\hazzem.jpg" );
          File file22=new File("g:\\copy2.jpg");
          FileManager.copy(file11,file22);

Answer 1

Try copying a byte array, it will go much faster, use a larger byte array say of size 1024 for example.
