Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream.

Usage

From source file:Main.java

public static void main(String[] args) throws IOException {
    int[] i = { 123, 234, 345, 456, 678 };
    FileOutputStream fos = new FileOutputStream("c:\\test.txt");
    DataOutputStream dos = new DataOutputStream(fos);

    for (int j : i) {
        dos.writeInt(j);//from   w ww .  ja  va 2 s. c  o m
    }
    dos.flush();

    InputStream is = new FileInputStream("c:\\test.txt");
    DataInputStream dis = new DataInputStream(is);

    while (dis.available() > 0) {
        int k = dis.readInt();
        System.out.print(k);
    }
}
