Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    FileInputStream fin = new FileInputStream("C:/Array.txt");
    DataInputStream din = new DataInputStream(fin);

    byte b[] = new byte[10];
    din.read(b);
    din.close();//  ww w.  j a va2s  .  c o m
}

    byte[] bs = new byte[count];

    dis.read(bs);

    for (byte b : bs) {
