In this example we are going to talk about java.net.SocketTimeoutException. This exception is a subclass of java.io.IOException, so it is a checked
We can use theternaryoperator for handling null pointers as follows: 1 String message = (str == null) ? "": str.substring(0, 10); The message variable will be empty ifstr’s reference is null. Otherwise, ifstrpoints to actual data, the message will retrieve the first 10 characters ...
