Java value transfer and reference transfer, java transfer reference Tian tianbo planted a big pitfall in the field of value transfer and reference transfer, resulting in a waste of time in the afternoon. let's first talk about passing and referencing values to the official e

The automatic reference count (Automatic Reference counting) is referred to as arc, which is Swift's tracking and management of application memory. Similar to the GC in Java, but not quite the same.Arc is the instance of the reference number 0,arc will destroy this instance.GC is when the program cannot access this ins
