在C语言中,可以使用传递指针的方式实现有效的Swap(),原因在于C提供了直接的取地址和引用地址的操作。Java则没有提供直接操作内存地址的操作,因此不容易实现形如swap(Object x,Object y)的方法。 Solution 在Java中实现交换,经常借助于数组,一般形式为 public static void exec(Object[] a, int x, int y); 1....

实时上java会分两步写入这个long变量,先写32位,再写后32位。这样就线程不安全了。如果改成下面的就线程安全了: 1 privatevolatilelongfoo; 因为volatile内部已经做了synchronized. CAS无锁算法 要实现无锁(lock-free)的非阻塞算法有多种实现方法,其中CAS(比较与交换,Compare and swap)是一种有名的无锁算法。CAS...
Swapping in Java:The swapping just above using reference parameters in C doesn't work in Java, since Java doesn't have these kind of parameters, but often an application really only needs to swap two values in an array. In this case one can pass the array and the two indexes to swap ...
