FileInputStream in FileOutputStream

	se uporabljata za branje in pisanje v datoteke;
	za branje in pisanje imata enake metode kot InputStream in OutputStream; torej read in write.

import java.io.*;
class testCopy {
    public static void main (String argv[]) {
        int c;
        FileInputStream fin;
        FileOutputStream fout;

        try {
            fin=new FileInputStream("lala");
            fout=new FileOutputStream("lala-copy");

            while ((c=fin.read())!=-1) {        // beremo do konca datoteke
                System.out.println((char)c);
                fout.write(c);                  // pišemo v drugo datoteko
            }
        }
        catch (FileNotFoundException e) {
            System.out.println("Ne morem odpreti datoteke " + e.getMessage());
        }
        catch (IOException e) {
            System.out.println("Napaka pri branju " + e.getMessage());
        }
        catch (Exception e) {
            System.out.println("Neka druga napaka");
        }
    }
}
