In a nutshell:

In a nutshell: -Monitor. Enter/exit and mutexes are commonly used for protecting objects From being used by two threads at the same time. Every thread acquires Mutex (resp. enters the monitor) before it uses the object, and no other Thread will be allowed to do the same until the mutex is released (resp. Monitor is exited); the monitor methods are faster and use less memory, Mutexes can be shared using SS Processes -The lock statement internally uses

Preface to "C #3.0 in a Nutshell, 3rd Edition"

Preface I recently read the book C #3.0 Core Technology in the library. I think it is quite good to read it. C #3.0 technology covers from basic syntax to new features, it is a good book to learn C #3.0. I wanted to download the electronic version from the Internet but couldn't find it, but I read the English version of C #3.0 in a Nutshell, 3rd Edition, also very good. I plan to take the time to learn something and write a few articles on my blog to

locked. Locking an object[] doesn ' t lock the individual objects.Locks a object[] array, and cannot lock every object within the array. Primitives is not mutable, so they can ' t (and don ' t need to) be locked.Native types are immutable, so they cannot (and do not need to) lock. Synchronized can ' t appear on a method declaration in an interface.Synchronization cannot appear on the method of an interface. Inner classes is just syntactic sugar, so locks on Inner classes has n

distinguish between these, kinds of equality. One of the "identical" when talking about equality of references and the word "equal" when Talking about a distinct objects that has the same content. To test-nonidentical objects for equality, pass one of the them to the Equals () method of the other: All objects inherit a Equals () method (from Object), but the default implementa‐tion simply uses = = to test for identity of references, not equality of content.

Either, directly re-implementing the JVM, directly explaining the language3,java and C + + differences: Java's function call is virtual by default Java always passes the value of the Java does not support multiple inheritance Java does not have operator overloading 4,java ignores all whitespace, tab, line breaks, and so on,

JAVA8 Method References-java In a nutshell, 6th

The relationship between the JAVA8 function reference and the lambda expression => function Reference is a simplified lambda expression that infers only the function, parameter, and return value compiler that appears. > Actually this grammar and lambda expression is exactly the opposite, NBSP;LAMBDA expression represents an anonymous method, which is the absence of a function name, giving only parameters and method bodies. Then the existing function comes in handy, the existing function has th

Eight sort algorithms that must be known [java Implementation] (3) Merge sort algorithms and Heap Sort Algorithms I. Merge Sorting Algorithm Basic Idea: The Merge Sorting method combines two (or more) ordered tables into a new ordered table, that is, the sequence to be sorted is divided into several subsequences, each of which is ordered. Then combine the ordered
