JDK1.0 introduces the first associated collection class Hashtable, which is thread-safe. All the methods of Hashtable are synchronous.JDK2.0 introduces the HashMap, which provides an unsynchronized base class and a synchronized wrapper synchronizedmap. Synchronizedmap is known as a conditional thread-safe class.The implementation of the map thread security introd

To understand the Thread Scheduling Principle and thread execution process, SCJP5 learning notes must understand the thread stack model. The thread stack refers to the stack information of Thread Scheduling in the memory at a certain time point. The method currently called i

Note: (previously only used handle because the main thread is added by default Looper.prepare () and Looper.loop (). So the main thread can send and receive information through the handle, but if inside the thread, that is, the worker thread, the worker thread, the default i

Thread priority preemption experiment [RT-thread Study Notes 3], rt-Thread Study Notes At the same time, the thread is in the ready state and runs first with a higher priority. When a high-priority task is ready, the low-priority task gives way to the CPU, so that the high-priority task is executed first. Create two ta

Life cycle: Threads also have a life cycle, and there are different states, transitions between states.New state, ready state, running state, blocking state, dead state.Someone puts the blocking state, the wait state, and the timing wait state together called the blocking state .The state of the thread object is stored in the inner class of the thread class:Note: The Thread.state class is actually an enumer

This chapter describes the lifecycle of a thread pool. In the "Java multi-thread series-" basic articles "01 Basic Concepts", we have introduced five States of threads: new state, ready state, running state, and blocking state, death status. The thread pool also has five States. However, the thread pool is different fr

1 Actual instructions for asyncFor a time-consuming process, we give it to someone else (like another thread) to execute, and we continue to work on it, and when someone else takes the time-consuming action and then feeds back the results, that's what we call async.We use an easy-to-understand threading mechanism to implement Asynchrony.2. Principle of the implementation of the co-process notationWhen using a callback function to write an asynchronous
