I want to append the above java lines in above code such that the socket should read only once i.e; in public static void main(final String[] args) and the buffered reader method along with while loop must be in public void actionPerformed(final ActionEvent e).
try {


Socket skt = new Socket("192.168.1.67", 5001);
//for(;;)
{
//Socket skt = new Socket("192.168.1.67", 5001);
BufferedReader in = new BufferedReader(new
InputStreamReader(skt.getInputStream()));
while (!in.ready()) {}
int value;
while((value = in.read()) != -1)
{

}
in.close();
}
}
catch(Exception e) {}
