abstract class和interface是Java语言中对于抽象类定义进行支持的两种机制,正是由于这两种机制的存在,才赋予了Java强大的面向对象能力。 abstract class和interface之间在对于抽象类定义的支持方面具有很大的相似性,甚至可以相互替换,因此很多开发者在进行抽象类定义时对于 abstract class和interface的选择显得比较随意。其实,两...

CAS通过调用JNI的代码实现的。JNI:Java Native Interface为JAVA本地调用,允许java调用其他语言。而compareAndSwapInt就是借助C来调用CPU底层指令实现的。 下面从分析比较常用的CPU(intel x86)来解释CAS的实现原理。sun.misc.Unsafe类的compareAndSwapInt()方法的源代码: ...
