System.gc()
和Runtime.gc()
有什么区别?
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.
