How many copies does a static variable have?
Short answer. One, shared by the whole class.
Does changing one object's name affect another?
No. Instance variables are separate.
Remember
| Instance: copy per object |
| static: one shared copy |
Fifty students, one school name. How many copies? Static school gets one shared box. Each object gets its own name box. Change school once, and every object sees it. Instance means a copy per object. Static means one shared copy.
