code convertion from c to java

please can someone help me convert this socket program to java

/* Client code in C */

#include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h>

int main(void) { struct sockaddr_in stSockAddr; int Res; int SocketFD = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

if (-1 == SocketFD)
{
  perror("cannot create socket");
  exit(EXIT_FAILURE);
}

memset(&stSockAddr, 0, sizeof(stSockAddr));

stSockAddr.sin_family = AF_INET;
stSockAddr.sin_port = htons(1100);
Res = inet_pton(AF_INET, "192.168.1.3", &stSockAddr.sin_addr);

if (0 > Res)
{
  perror("error: first parameter is not a valid address family");
  close(SocketFD);
  exit(EXIT_FAILURE);
}
else if (0 == Res)
{
  perror("char string (second parameter does not contain valid ipaddress)");
  close(SocketFD);
  exit(EXIT_FAILURE);
}

if (-1 == connect(SocketFD, (struct sockaddr *)&stSockAddr, sizeof(stSockAddr)))
{
  perror("connect failed");
  close(SocketFD);
  exit(EXIT_FAILURE);
}

/* perform read write operations ... */

shutdown(SocketFD, SHUT_RDWR);

close(SocketFD);
return 0;

}

It would be great if you could tell us what exactly are you trying to achieve in the program. Java has its own packages for Sockets, but just a gist would help understand better.

You have probably figured out what you wanted to do by now, but for the sake of future viewers of this topic; there is already a Socket class in Java that should suite most, if not all, of your needs.
