Specific domain language (domain-specific languages,dsl) has become a hot topic; Many functional languages are popular, mainly because they can be used to build DSLs. In view of this, in the final article of the Scala Guide series for Java developers, Ted Neward continues to discuss a simple calculator DSL to demonstrate the power of functional languages in building an "external" DSL, and in this process to

same time also is the Internet knowledge redundant disorder initiator, because some people like to copy things, but also does not indicate the original text. This kind of blog must be identified.Seven, finally to the source codeI think this part of us all have to frown, read the source code, is the ultimate step of learning. Learn the architecture and code of good work. This doesn't have to be self-enforcing, but I have to recommend that you develop good habits,1. To the official website, find

, it wakes the thread and re-holds the Spilllock lock.As can be seen here, the use of lock can make our multi-threaded interaction easier, and the use of synchronized does not do this.Finally, the Reentrantlock class also provides 2 mechanisms for competitive locking: Fair lock and unfair lock. The meaning of these 2 mechanisms can literally be understood: that for multithreading, a fair lock relies on the order in which threads come in, and the subsequent thread gets a lock. The non-fair lock m

the initialization of the instance member is after the static member. 3. A static domain in a class can be accessed either by an object name or by a class name. "Solved the problem.Last week's experimental exercise is just a small test sledgehammer, this week's program has made me feel small difficulty, although clear algorithm, but always to C language inertia to consider, to write programs, sometimes a little messy, which caused my program has a lot of grammatical errors, although looking at

examples are as follows:Bytebuffer Header = bytebuffer.allocate (+); Bytebuffer body = bytebuffer.allocate (1024x768= {header, Body};channel.read (Bufferarray);Note that buffer is first inserted into the array, and then the array is used as the input parameter of the Channel.read (). The read () method writes the data read from the channel into buffer in the order of buffer in the array, and when one buffer is full, the channel is written to the other buffer.Scattering reads before moving the
