Scope refers to the lifetime of a variable.
There are four basic scopes:
Static variables live basically as long as their class lives.
Instance variables live as long as their object lives.
Local variables live as long as their method is on the stack; however, if their method invokes another method, they are temporarily unavailable.
Block variables (e.g.., in a for or an if) live until the block completes
