Runtime.totalMemory介绍

[英]Returns the number of bytes taken by the heap at its current size. The heap may expand or contract over time, as the number of live objects increases or decreases. See #maxMemory for the maximum heap size, and #freeMemory for an idea of how much the heap could currently contract.
[中]返回堆在其当前大小下占用的字节数。随着活动对象数量的增加或减少，堆可能会随着时间的推移而扩展或收缩。请参阅#maxMemory了解最大堆大小，以及#freemory了解堆当前可收缩的大小。
