Usage

From source file:Main.java

public static byte[] getBodyBytes(String ip, String port, String key)
        throws NumberFormatException, IOException {

    String[] ipArr = ip.split("\\.");
    byte[] ipByte = new byte[4];
    ipByte[0] = (byte) (Integer.parseInt(ipArr[0]) & 0xFF);
    ipByte[1] = (byte) (Integer.parseInt(ipArr[1]) & 0xFF);
    ipByte[2] = (byte) (Integer.parseInt(ipArr[2]) & 0xFF);
    ipByte[3] = (byte) (Integer.parseInt(ipArr[3]) & 0xFF);

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    DataOutputStream dos = new DataOutputStream(baos);
    dos.write(ipByte);/* w w  w .j a  v  a2  s.co m*/
