SequenceInputStream
In this chapter you will learn:
Use SequenceInputStream
SequenceInputStream class concatenates multiple InputStreams.
Constructors from SequenceInputStream:
SequenceInputStream(InputStream first, InputStream second)
a pair of InputStreamsSequenceInputStream(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.
import java.io.FileInputStream;
import java.io.IOException;
import java.io.SequenceInputStream;
/*from j a v a 2s . c o m*/
public class Main {
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();
}
}
