How to copy the content of one file into another

Question

I have tried this code
try {
               fin = new FileInputStream("file path");
          catch(FileNotFoundException exc)
               System.out.println("File not found");
               return 0;
          catch(ArrayIndexOutOfBoundsException exc)
               System.out.println("Usage: Showfile file");
               return 0;
          while(true){
               i=fin.read();
               if(i==-1)
                    break;
               cnt++;
          fin.close();*/
now in this way i can lift one character at a time and copy it into another file (note i have not done the copy part in this code but that can be implemented) however this whole procedure is taking too much time if the size of the file is too big....kindly suggest another way to copy one file into another

Answer 1

have you ever copied and pasted a large file in Windows or another OS? Larger files take more time to copy, that's just how it is.
