Figure 9-17 displays the accessor method and mutator method for the
expiresNotifyLimit instance variable of the Password class. Recall that the number
contained in this variable is used to determine if the password will expire soon.

79 public int getExpiresNotifyLimit ()

80 {

81 return expiresNotifyLimit;

82 }

83
84 public void setExpiresNotifyLimit ( int newNotifyLimit )

85 {

86 if ( newNotifyLimit >= 2 && newNotifyLimit <= 20 )

87 expiresNotifyLimit = newNotifyLimit;

88 }
