    正确答案： A
    解析： Java语言将内存分配和释放的工组交给了自己，程序员不必做这些工作，它提供一个系统级的线程跟踪每个内存的分配，在JVM的空闲处理中，垃圾收集线程将检查和释放不再使用的内存（即可以被释放的内存）。垃圾收集的过程在java程序的生存期中是自动的，不需要分配和释放内存，也避免了内存泄漏。可以调用System.gc()方法建议（suggest）JVM执行垃圾收集以使得可被释放的内存能立即被使用，当此方法返回的时候，JVM已经做了最大的努力从被丢弃的对象上回收内存空间。程序员不能指定收集哪些内存，一般而言也不用关心这个问题，除非是程序的内存消耗很大，特别是有很多临时对象时可以“建议“进行垃圾收集以提高可用内存。需要指出的是调用System.gc()方法不能保证JVM立即进行垃圾收集，而只能是建议,因为垃圾收集线程的优先级很低（通常是最低的）。
