Control statements generally direct the flow of programs based on any desired condition. Control mechanisms such asif, else, switch, and loops like for, while, and do-whileare available in Java. These features will enable the implementer to perform the execution of blocks depending on a specific...
This is a great example of the "vertical" problem in practice. This code is a little difficult to read. In addition, we have to write custom search criteria for each use case. Lambda Expressions Get it Just Right Lambda expressions solve all the problems encountered so far. But first a ...
Java Concurrency in Practice (1st edition) - Brian Goetz Java Concurrency in Practice is a helpful reference book, offering a wide range of concurrency APIs and mechanisms. It also covers design rules, mental models, and patterns so that you can create concurrent programs with ease. This Java...
We have already seen an example of static security properties (that is, registering a provider statically via the "security.provider.i" security property). If you want to set properties dynamically, trusted programs can use the following methods:...
the speed of non critical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we...
Destination names beginning with the lettersmqare reserved and should not be used by client programs. Also, for topic destinations, a symbolic lookup name that includes wildcard characters can be used as the lookup string.

Therefore, previous work [4, 14, 18] provided refactoring tools for improving the concur- rency of Java programs. Based on investigations of real programs, previous work [3, 8] proposed two typical refactoring methods. One is atomic refactoring that allows the programmer to use an operation on...
This paper presents an approach for the automated debugging of reactive and concurrent Java programs, combining model checking and runtime monitoring. Runtime monitoring is used to transform the Java execution traces into the input for the model checker, the purpose of which is twofold. First, it...
