import java.io.*;

public class Demo {
    public static void main(String[] args) {

        // create two  new strings with 5 characters each
        String s1 = "Hello";
        String s2 = "World";

        // create 2 input streams
        byte[] b1 = s1.getBytes();
        byte[] b2 = s2.getBytes();
        ByteArrayInputStream is1 = new ByteArrayInputStream(b1);
        ByteArrayInputStream is2 = new ByteArrayInputStream(b2);

        // create a new Sequence Input Stream
        SequenceInputStream sis = new SequenceInputStream(is1, is2);

        try {
            // read 10 characters, 5 from each stream
            for (int i = 0; i < 10; i++) {
                char c = (char) sis.read();
                System.out.print("" + c);
            }

            // change line
            System.out.println();

            // start closing the streams
            System.out.println("Closing Streams...");

            // close the streams
            sis.close();
            is1.close();
            is2.close();

            // print message for closed streams
            System.out.println("Streams Closed.");

        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
}

输出结果为：

HelloWorld
Closing Streams...
Streams Closed.
