For an experienced Java developer who can access source code, any program can be seen as a transparent model in the museum. Similar to thread dumping, method call tracking, breakpoint, and aspect (profiling) statistical tables and other tools let us know what operations the program is currently performing, what operations it has just done, and what operations it will do in the future. However, this is not so obvious in the product environment. These t

being unusable or dirty. An empty catch block can only become meaningless, and if you are very certain that an exception will not continue to affect the state of the object in any way, it is still the best method to log errors during program execution. For writing exception handling code in Java programming, this is not just a Java best practice, but a most comm

In the latest Android platform (starting from Android 2.3), a new class is added, called strictmode (Android. OS. strictmode ). This class can be used to help developers improve their applications and provide various policies. These policies can be used to check and report problems existing in

more recommendations, I only mention a few: Java How to programme seems to be recognized as the classic textbook, I naturally do not deny his value. About thinking in Java, personal feel is not too suitable for beginners, into the door to see the feeling better, the reader is very useful. Also very willing to recommend effective Java, this book won the Jolt A

code does not contain those blocking calls, or that a non-synchronous method exists in an object that uses the synchronization blocking code. Although this method requires some attention to ensure the safe operation of the result code, it allows the object to still respond to other threads after the thread with the object is blocked. Design for different thread ModelsDetermining whether the thread model is preemptible or collaborative depends on the real-time users of the Virtual Machine and va
