Как запустить этот код?

Сам не шарю, можете помочь?)

public class Main {

private static InputStream is = null;
private static OutputStream os = null;
private static Socket socket = null;

public static ArrayList names = new ArrayList();

public static void main(final String[] args) throws IOException {
while(true){
connect("127.0.0.1", 12345);
disconnect();
}
}

private static String randomnick(final int n) {
char[] array = new char[n];
int rand;
Random r = new Random();
for (int i = 0; i< n; i++) {
rand = r.nextInt(26) + 'a';
array[i] = (char)rand;
}
return new String(array);
}

private static void connect(final String ip, final Integer port) throws IOException {
socket = new Socket(ip, port);
is = socket.getInputStream();
os = socket.getOutputStream();
}

private static void disconnect() throws IOException {
socket.close();
}
