因此之所以在getAndSet方法中调用一个for循环,即保证如果调用compareAndSet这个方法返回为false时,能再次尝试进行修改value的值,直到修改成功,并返回修改前value的值。 整个代码能保证在多线程时具有线程安全性,并且没有使用java中任何锁的机制,所依靠的便是Unsafe这个类中调用的该方法具有原子性,这个原子性的保证并不...
In this problem, we need to swap numbers in java. Swapping is the process of changing the values kept in two variables. The values of two variables can be changed in a variety of ways. Simple mathematical operations like addition and subtraction, multiplication and division, or bitwise XOR ca...

A swapping values:In C and in Java, we can always swap values with the use of three assignment statement and no function or paramters. The code on the left shows this, while the code on the right shows how the same task can be accomplished using the Cexclusive-oroperator^. (Notice th...

This means that a JRuby object is not much more than a map from method names to their implementations and from field names to their values. The implementations for those methods are contained in anonymously named classes that are generated when the method is encountered. If you add a method,...
