system.gc() 和 runtime.gc() 之间的区别

Difference between system.gc() and runtime.gc()(system.gc() 和 runtime.gc() 之间的区别)

问题描述

System.gc()和Runtime.gc()有什么区别?

推荐答案

两者都是一样的.System.gc() 实际上等同于 Runtime.gc().System.gc()内部调用Runtime.gc().

Both are same. System.gc() is effectively equivalent to Runtime.gc(). System.gc()internally calls Runtime.gc().

唯一的区别是 System.gc() 是一个类方法，而 Runtime.gc() 是一个实例方法.所以，System.gc()更方便.

The only difference is System.gc() is a class method where as Runtime.gc() is an instance method. So, System.gc() is more convenient.
