called the root node, the garbage collector traverses each object from the root node, marking the accessible object as "valid" (with one exception being a weak reference, followed by a detailed chapter). An island object outside this tree or a collection of islands objects formed by circular references is marked as "invalid", and the garbage collector destroys these invalid objects at the right time and completes a garbage collection. The garbage collector is a low priority daemon running in a

library is used to mark uninitialized Style = "color: # ff6600"> stack memory In the VC debug version, the assigned values in the stack are first processed with 0xcccccccc. Therefore, in the debug mode, the debugging program finds that values such as 0xcccccccccc are referenced, it indicates that an uninitialized value is being used. This is one of the benefits of debugging in debug mode. If the release

Therefore, it is normal to return null.
