Static synchronization is applied to static methods or blocks. When a method or block is declared as static and synchronized, it means the lock is acquired on the class object itself (represented by Class.class). Only one thread can acquire the lock on the class object, preventing other threa...
Exceptions are an important feature of the Java language and a basic control flow. In the Java language, a function is allowed to have one return value and throw multiple different types of exceptions. The return value of the function is a normal exit. The function return indicates that the ...

Implement the interactions in a “pseudo-transaction” that explicitly checks for and manages error conditions and rollback. This approach is appropriate when when business rules dictate the need for keeping data in target resources synchronized, one or more target resources are non-transactional and ...

Hence, the induced noisy activity may be synchronized with the ongoing relevant signal (Ermentrout, Galan, & Urban, 2008), thereby rendering the signal stronger (Miniussi, Harris, & Ruzzoli, 2013). In other words, behavioural facilitation may result from an optimum level of noise. In the ...
This is achieved through the use of dual lock-stepped microprocessors (executing the same instructions in a fully synchronized manner) with comparison circuits to detect errors in their operation, and self-checking logic to detect errors in the remaining circuitry within the controller. The two ...
In addition to initialization, it may be advantageous to create and initialize an instance of the specification class immediately prior to invoking any methods of the specification class. This “just-in-time” instantiation enables the state of the implementation to remain synchronized with the state...
