Reference Memory
It is correct
mh
if a variable is of value type memory is allocated on stack memory.. if it is of reference type,memory is allocated on heap memory..
Memory works on reference points. Like a file system. If you can't remember something that's because the reference to that particular thing is missing.
You can say that
All references must be non-null, therefore they will always have memory allocated to them. A reference is simply a non-null memory location that stores a specific type of variable, as determined by the reference's type. The reference name is an alias (a token) for the memory location, in much the same way that an array name is an alias for the starting address of the array. A pointer variable is different in that memory must be set aside for the pointer variable itself, in addition to the memory it actually points to. On a 32-bit system, 4 bytes must be allocated to every pointer variable, to store the memory address that they point to, which could be null. But references only occupy the memory they actually refer to, which can never be null (a null reference will in fact render the program invalid).
The idea of a reference count is so that you do not have to keep multiple copies of the same data in memory. Each new occurrence of the value just increments a reference count. This cuts down on memory utilization.
An object is the actual storage space in memory in which some collection of data resides.A reference variable is a variable which refers to the memory location of an object.Look at the pseudocode below:Object obj = new Object();Here obj is the reference variable, and the data to which it refers is the object.
