0238 SequenceInputStream class
<![CDATA[
SequenceInputStream class concatenates multiple InputStreams.
Constructors from SequenceInputStream:
SequenceInputStream(InputStream first, InputStream second)
a pair of InputStreams
SequenceInputStream(Enumeration <? extends InputStream> streamEnum)
an Enumeration of InputStreams
SequenceInputStream reads from the first InputStream until it runs out and then switches over to the second one.
Revised from Open JDK source code

public static void main(String args[]) throws IOException {
SequenceInputStream inStream;
FileInputStream f1 = new FileInputStream("file1.java");
FileInputStream f2 = new FileInputStream("file2.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();
}
