Before swapping the numbers: First number = 11 Second number = 22 After swapping the numbers: First number = 22 Second number = 11 The value of the first number and the second number are switched using a temporary variable, as can be seen in the output. Swap Two Numbers in Java Without...
2. 也可以通过重新定义个类(在JAVA中我们可以通过使用int的包装类---Integer,然后将其作为值的引用传到函数中,但这个Integer包装类也不允许你来改变它的数据域;但这不防碍我们用自己的包装类,比如说下面实现的MyInteger): 1. //MyInteger: 与Integer有些类似,但是其对象可以变值 2. class MyInteger { 3. priva...

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...
