or “->” operator with a set/get method. IDE’s are so good at generating “boiler plate” code that the benefits of this feature seems minimal at best. Certainly not great enough to justified this change IMHO. Kind regards, Kirk The Cafes » What Properties in Java Should Have ...
In this syntax, the, first method only uses one colon and specifies the start and stop values. The second method includes a second colon, where the value before the first colon is the start, the middle value is the step, and the last value is the stop....

In the scenario outlined above, what do you think is going to happen? AddProduct is a non virtual method call, so it cannot be intercepted. Accessing the _products field also cannot be intercepted. The end result is a NullReferenceException that will seem to appear randomly, based on whatev...

This technique can be used in some complex synchronization scenarios. As the parking uses a binary semaphore, we cannot add up permits, and two unpark calls wouldn’t produce two permits: privatefinalThreadparkedThread=newThread() {@Overridepublicvoidrun(){ LockSupport.unpark(this); LockSupport.un...
