- Variables/fields/parameters store a single value.
- They range from 1 byte to 8 bytes in most languages.
- At the statement `m = new PVector();` the operator `new` creates a contiguous memory block enough to fit in all PVector’s non-`static` fields.
- And when it’s done, it returns the 1st memory address of that block.
- And finally, that 1st memory address is stored in the field _m_ as a reference value.
- Now, when you do `pressLoc = m`, you’re assigning field _pressLoc_ w/ the exact value of _m_.
- After that assignment, both _m_ & _pressLoc_ fields point to the same PVector object, b/c they now store the same 1st memory address value of it.
- In other words, they’re now alias to the same object.
