Java监视内存使用情况，运行Java 程序一般要消耗大量的内存，这曾经是java 的一个致命弱点。当然随着硬件的飞速发展，这个缺点有所弱化，同时java 虚拟机的逐渐成熟，也使内存的消耗量减少。那么一个较小java 程序 　　究竟要消耗多少内存呢？本例将实现一个能自我监视内存使用的简单程序，来评估java 程序的内存消耗情况。(Java monitor memory usage, run Java programs generally consume large amounts of memory, which used to be a fatal weakness of java. Of course, with the rapid development of hardware, this shortcoming has been weakened, while mature java virtual machine, but also to reduce memory consumption. Then a small java program How to consume much memory? This example of a simple program memory can be used for self-monitoring to assess memory consumption java program.)
