Is it legal to declare a variable in one method which has the same name as a variable declared in another method? If this is so how are they related and if the value of one of these variables is changed what effect is apparent in the other variable?

Yes. Local variables declared in different methods can have the same names. They are distinct variables and will not interfere with each other.

It is legal to declare two variables with the same name if they are in two different methods. Each one occupies its own spot in memory and is directly associated with the method in which it was created. Remember that that a variable lives and dies within the curly braces of its parent method. Changing the value of one does not affect the value of the other.
