示例1: getGCStatst
import java.lang.management.GarbageCollectorMXBean; //导入方法依赖的package包/类
/**
* Returns a map of garbage collectors and their stats.
* The first object in the array is the total count since JVM start and the
* second is the total time (ms) since JVM start.
* If a garbage collectors does not support the collector MXBean, then it
* will not be represented in the map.
* @return A non-null map of garbage collectors and their metrics. The map
* may be empty.
