-threaded execution is faster, because the "array sum" itself does not require additional resources and is not blocked.Instead, multiple threads increase the time overhead of "thread scheduling".You can also see that the CPU calculation is very fast. The "200000000" 200 million integers add up to a time of less than 0.1 seconds.episodeWhen I first looked at the code, I misunderstood it. Think "the number of CPU cores split task", this time "multithreading
Multithreading and concurrency issues are among the questions that interviewers prefer to ask in a Java technology interview. Here, the most important questions are listed from the interview point of view, but you should still have a solid grasp of the basics of Java multithreading to match the problems you encounter later. ( proof Note: Very much agree with this
The introduction of multithreading concept is one of the embodiment of the effective compaction of the Zhai computer, and this is also very necessary, because the general operation of the process involves the reading of data, such as from disk, other systems, databases, CPU speed and data read speed has a serious imbalance, During the execution of a thread, a number of nodes will become blocked, making the calculation inefficient. In addition, the ser

The following is transferred from http://ifeve.com/java-concurrency-thread/:In the past single-CPU era, single-tasking can only execute a single program at a point in time. Later in the multitasking phase, computers can perform multitasking or multiple processes in parallel at the same point in time. Although it is not really the "same point in time", but multiple tasks or processes share a CPU, and the operating system to complete the multi-tasking C
. Whatever it takes to fit your system.A simpler concurrency modelEvery system running on its own thread in the same threading system can be implemented as a single thread. This means that the internal concurrency model is much simpler than the thread-sharing state. You don't have to worry about all the concurrency problems that can result from concurrent data st

do not need to use the Futuretask class, it becomes very useful when we intend to rewrite some methods of the future interface and keep the original base implementation. We can just inherit from it and rewrite the methods we need. Read the Java futuretask example to learn how to use it.7. What is the implementation of concurrent containers?Java collection classes are fast failures, which means that when a collection is changed and a thread iterates through the collection using Iterators, the ne
The development trend of 1.CPU:The number of cores will continue to grow, and, according to Moore's Law, a typical PC desktop may return to the 24 core in 2018 due to a serious bottleneck in the single core performance improvement.2. The difference between multithreading and parallel computing:All concurrent processing have queued, wake up and execute these three steps, so concurrency is a macro concept, on

1. Introduction to Concurrency and multithreadingThe original computer was single-tasking and later developed to run multiple tasks (processes) in parallel, scheduled by the operating system, and each task could get a time slice. Under multitasking, each task needs to release resources to other tasks after the system resources have been used.Later, the same task internal development of multiple threads concurrent operations, the same memory space for
