Detailed sequence input stream

(Watch my blog - "Detailed byte stream" )

SequenceInputStream categories:

The concept :

Represents other input stream is the logical concatenation of
it from the ordered set of input stream begins,
and start reading from the first input stream , until the end of the file ,
followed by a second read from the input stream ,
and so on, until reaching contains the last till the end of the file input stream

This stream can be tough in the information file merge multiple InputStream subclasses .

Well, now, I have to show this flow constructor :

Constructor :

• SequenceInputStream (InputStream s1, InputStream s2)
  by remembering these two parameters to initialize a newly created SequenceInputStream
  (in sequence to read these two parameters, the first reading s1, then read s2),
• SequenceInputStream (Enumeration <? Extends InputStream> e)
  Initializes a newly created SequenceInputStream by remembering parameters,
  this parameter must be generated runtime Enumeration type parameters of type InputStream object

Now, I have to show this kind of commonly used API :

Common API :

• int available ()
  estimates returns read without blocking (or skipped) from the bottom of the current number of bytes in the input stream,
  the method is invoked by a single input stream to the bottom of the current methods
• void close ()
  Closes this input stream and releases any system resources associated with the stream
• int read ()
  from this input stream to read the next data byte
• int read (byte [] b, int off, int len)
  up to len bytes of data from this input stream into a byte array

Well, now, I have to show using the lower part of the API:

package edu.youzg.about_io.about_file.core.Test;

import edu.youzg.about_io.about_file.core.FanInfo;

import java.io.*;
import java.util.Enumeration;
import java.util.Properties;
import java.util.Vector;

public class Test {

    public static void main(String[] args) throws IOException, ClassNotFoundException {
        FileInputStream in1 = new FileInputStream("JoJo.properties");
        DataInputStream in2 = new DataInputStream(new FileInputStream("plantsVSzombies.mp4"));
        SequenceInputStream in = new SequenceInputStream(in1, in2);
        FileOutputStream out = new FileOutputStream(new File("summary.txt"));

        int len = 0;
        byte[] bytes = new byte[1024 * 8];
        while ((len = in.read(bytes))!= -1){
            out.write(bytes,0,len);
            out.flush();
        }
        out.close();
        in.close();

    }

}

Now, I have to show the next two source file information:

I come to show the next generation of information files:

you can see, the two files with different flow packed file, the code is merged into a specified file.
