多谢,已解决.rds=new DatagramSocket(8880);           
byte[] rebuf=new byte[256];
            rdp=new DatagramPacket(rebuf, rebuf.length);
            try {  
                //设置超时时间,3秒  
                rds.setSoTimeout(3000);  
                rds.receive(rdp);
                msg=new String(rebuf,0,rdp.getLength());         
                rds.close();        
             System.out.println("Receive部分完成11111");
             System.out.println("Receive msg(YES/NO):"+msg);         
             if(msg.equals("YES"))
             {
             /*int option = JOptionPane.showConfirmDialog(null,"点击确认下载或取消","P2P",JOptionPane.YES_NO_OPTION);
                 if (option == JOptionPane.YES_OPTION)
         {
                 download();
         }*/
             System.out.println("Receive部分完成22222");
             JOptionPane.showMessageDialog(null, "点击确认下载", null, JOptionPane.OK_OPTION);
             download();
            
             }
             if(msg.equals("NO"))
             {
             JOptionPane.showMessageDialog(null, "对方不同意共享此文件!", null, JOptionPane.OK_OPTION);
             } 
            } catch (Exception e) {
             rds.close(); 
             JOptionPane.showMessageDialog(null, "对方无应答!", null, JOptionPane.OK_OPTION);
         System.out.println("对方无应答!"); 
            }
