java 强制垃圾回收代码，java强制垃圾回收,package cn.o

package cn.outofmemory.snippets.core;public class RunTheGarbageCollector {    public static void main(String[] args) {        // Run garbage collector by using gc static method of System class        System.out.println("Suggesting VM to run garbage collector");        System.gc();        System.out.println("Suggested VM to garbage collect objects");    }}

输出：

Suggesting VM to run garbage collectorSuggested VM to garbage collect objects

注意： 这种方法并不一定能让VM执行垃圾回收，是否真的马上执行垃圾回收要看JVM的策略
