------ Solution ----------------------------------- ---------
to set the receive delay in the delay did not receive a reply will throw an exception
------ For reference only ------- --------------------------------
Thank you , has been resolved.

rds = new DatagramSocket (8880);
byte [] rebuf = new byte [256];
rdp = new DatagramPacket (rebuf, rebuf.length);
try {
/ / set the timeout , 3 seconds
rds.setSoTimeout (3000);
rds.receive (rdp);
msg = new String (rebuf, 0, rdp.getLength ( ) ) ;
rds.close ();
System.out.println ("Receive partially completed 11111" ) ;
System.out.println ("Receive msg (YES / NO):" + msg) ;
if (msg.equals ("YES"))
{
/ * int option = JOptionPane.showConfirmDialog (null, " Click OK to download or cancel "," P2P ", JOptionPane.YES_NO_OPTION);
if (option == JOptionPane.YES_OPTION)
{
download ();
} * /
System.out.println ("Receive partially completed 22222 " ) ;
JOptionPane.showMessageDialog (null, " Click OK to download ", null, JOptionPane.OK_OPTION);
download ();

}
if (msg.equals ("NO"))
{
JOptionPane.showMessageDialog (null, " they do not agree to share this file ! " null, JOptionPane.OK_OPTION);
}
} catch (Exception e) {
rds.close ();
JOptionPane.showMessageDialog (null, " the other party does not answer !", null, ; JOptionPane.OK_OPTION);
System.out.println (" no other answer ! " ) ;
}
posted code to solve post to share with you .
