Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    InetAddress addr = InetAddress.getByName("java.sun.com");
    int port = 80;
    SocketAddress sockaddr = new InetSocketAddress(addr, port);

    Socket sock = new Socket();

    int timeoutMs = 2000;
    sock.connect(sockaddr, timeoutMs);
}

From source file:Main.java

    Socket sock = new Socket();

    int timeoutMs = 2000; // 2 seconds
    sock.connect(sockaddr, timeoutMs);
