I really need help on these 12 questions about java.

1) How can you tell a method is a constructor?

2) Would public void cheese() be considered a constructor?

3) Does it make sense to have private or void accessor method?

4) Would public void setName() be a good mutator declaration?

5) How can you tell the difference between instance and class variables?

6) Can we write name = name; and what would it mean?

7) How can you tell which version of the constructor is being called?

8) What does the . operator do for objects?

9) Can you use a loop to implement calcSubTotal?

10) Can you tell when and where we do the recursion in run()?

11) What does this refer to?

12) Give the code to implement public void setName(String name) { }.
