SequenceInputStream

Sequence IO

   <source lang="java">

import java.io.FileInputStream; import java.io.IOException; import java.io.SequenceInputStream; public class SequenceIOApp {

 public static void main(String args[]) throws IOException {
   SequenceInputStream inStream;
   FileInputStream f1 = new FileInputStream("ByteArrayIOApp.java");
   FileInputStream f2 = new FileInputStream("FileIOApp.java");
   inStream = new SequenceInputStream(f1, f2);
   boolean eof = false;
   int byteCount = 0;
   while (!eof) {
     int c = inStream.read();
     if (c == -1)
       eof = true;
     else {
       System.out.print((char) c);
       ++byteCount;
     }
   }
   System.out.println(byteCount + " bytes were read");
   inStream.close();
   f1.close();
   f2.close();
