推荐答案

详细：gc 在每个gc集合之后立即打印并打印有关每一代内存详细信息的详细信息以下是有关如何阅读详细gc 的博客

verbose:gc prints right after each gc collection and prints details about each generation memory details. Here is blog on how to read verbose gc

如果您正在尝试查找内存泄漏，请详细说明：gc可能还不够。使用一些可视化工具，如 jhat （或） visualvm 等，

If you are trying to look for memory leak, verbose:gc may not be enough. Use some visualization tools like jhat (or) visualvm etc.,

 4416K->512K(4928K), 0.0081170 secs

Before GC used memory is 4416K
