Reads some number of bytes from the input stream and stores them into the buffer array b.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {

    ObjectOutputStream out = new ObjectOutputStream(
            new BufferedOutputStream(new FileOutputStream("file.data")));
    out.write("java2s.com".getBytes());
    out.close();// w w w .  jav  a2  s. c  o  m

    ObjectInputStream in = new ObjectInputStream(new BufferedInputStream(new FileInputStream("file.data")));

    byte[] byteArray = new byte[10];
    in.read(byteArray);
    System.out.println(Arrays.toString(byteArray));
    in.close();
}
