This article is the fourth in the GC expert series. In the first understanding of Java garbage Collection, we learned several different GC algorithm processing processes, the way GC works, the difference between the new generation and the old age. So, you should have known about the 5 GC types in JDK 7, and the performance impact of each GC.The second monitoring of Java

? This is the mystery of these classes under the atomic package: The language level does not do the processing, we put it to hardware-cpu and memory, using the CPU's multi-processing capabilities, hardware-level blocking, coupled with the characteristics of volatile variables can be implemented based on atomic operation of thread safety. So, CAS is not non-blocking, but blocking is not in terms of language, threading, but on the hardware level, so no doubt such operations will be faster and more
