How to detect if a link has signal with Java ?

Question

Is there a way to detect if a link like the following examples has signal with a Java method ? If you cut and paste them into your browser's url field, you'll see the first one has signal but the 2nd has none, so if I have a Java method like this, how to detect the signals ?

boolean hasSignal(String Link)  // Link = "mms://online.ntdtvcast.com/Stream-Live"
{
 ... ??? ...
}
