Android source code analysis-system_server Process Analysis In the previous blog, we analyzed the Zygote process. We know that the Zygote process creates an important process-the system_server process and enters an infinite loop, later, an important task in the Android system was handed over to the system_server process. As the eldest son process of zygote, The s

Java concurrent series of AbstractQueuedSynchronizer source code analysis (summary analysis ), To learn Java concurrent programming, you have to understand the java. util. concurrent package. This package contains many frequently used concurrent tool classes, such as ReentrantLock, CountDownLatch, CyclicBarrier, and Semaphore. The underlying implementation of the

Applicationservice, except for the list.dynamicapiverbhelper: Returns httpverb by convention

Learn Java concurrency programming have to understand java.util.concurrent this package, this package has many of the concurrency tools we often use, such as: Reentrantlock, Countdownlatch, Cyclicbarrier, Semaphore and so on. The underlying implementations of these classes depend on the Abstractqueuedsynchronizer class, which shows the importance of this class. So in the Java Concurrency Series I first abstractqueuedsynchronizer this class to analyze, because this class is more important, and th
