This semester we began to learn the Java programming language, just beginning to get the Java textbook, my heart is dashed, because what? It's because the textbook is the thickest I've ever seen. Last semester, I felt the C language textbook is very thick, but not the thickest, only thicker. The thickness of the Java t

product code) Write the Product Code Test Pass Refactor the code and ensure the test passes (refactoring the next lab session) Cycle through the development of all functions Based on TDD, we don't have an over-design situation where the requirements are expressed through test cases, and we just 产品代码 let the test pass. There is a unit test tool JUnit in Java to aid TDD, and we use TDD to rewrite the example of the previous percent

Java concurrent programming and java concurrency The reason why Latch and Barrier are put together is that they give people a similar feeling.They all block some behaviors until an event occurs, but Latch is waiting for an event, while Barrier is waiting for the thread. First, compare the descriptions of the two in JCIP:Latch-A latch is a synchronizer that can de

Java concurrent programming and java concurrency This article records the immutability of the policy to ensure concurrency security. (Note: It is Immutable, not Invariant !) Organizes a series of actions into an atomic operation to ensure immutability conditions, or uses a synchronization mechanism to ensure visibility, to prevent reading of invalid data or chan

does not depend on class-specific instances and is shared by all instances of the class. The definition of a method must have a return value type modifier, one of which indicates that the method has no return value, and that the keyword is void. The main () method is the entry method for the Java application, which means that the first method to execute is the main () method when the program is running. 2. Object-oriented

: Initializes the resource with a specialized class.* The JVM will defer initialization of Resourceholder until the class is started, and the resource is initialized with a static initialization, so no additional synchronization is required.* When any thread calls GetResource for the first time, it causes Resourceholder to be loaded and initialized, at which point the static initializer will perform the resource initialization operation.*/ Public classresourcefactory{PrivateStaticclassresourceho
