The codes are: CT for Connecticut, MA for Massachusetts, ME for Maine, NH for New  Hampshire, NJ for New Jersey, NY for New York, PA for Pennsylvania and  VT for Vermont. In AutoPolicy method setState, use the logical OR (||)  operator(Section 5.9) to create a compound condition in an if...else  statement that compares the method's argument with each two letter  code. If the code is incorrect, the else part of the if...else  statement should display an error message. In later chapters, you'll  learn how to use exception handling to indicate that a method received  an invalid value.
