## 24.58 java.io.SequenceInputStream (JDK 1.0)

###

This class provides a way of seamlessly concatenating the data from two or more input streams. It provides an `InputStream` interface to a sequence of `InputStream` objects. Data are read from the streams in the order in which the streams are specified. When the end of one stream is reached, data are automatically read from the next stream. This class might be useful, for example, when implementing an "include file" facility for a parser of some sort.

    public class SequenceInputStream extends InputStream {
        // Public Constructors
                public SequenceInputStream(Enumeration e);
                public SequenceInputStream(InputStream s1, InputStream s2);
        // Public Instance Methods
            1.1  public int available() throws IOException;  // Overrides InputStream
                public void close() throws IOException;  // Overrides InputStream
                public int read() throws IOException;  // Defines InputStream
                public int read(byte[] buf, int pos, int len) throws IOException;  // Overrides InputStream
    }
