Question about the task We're all friends here, even the exceptions
Java Syntax, Level 9, Lesson 8
Under discussion
I'm so lost. How do I throw and exception that's in an extends class I have no clue what to do now. I tried throwing an exception right after the extends code and that ended in an error. I also tried to throw the error in the body of the method and had errors. Please help. Thank you for your assistance.

Java Syntax, Level 4, Lesson 1

Why Apple.addPrice needed in addPrice method?According to the lesson, static method can not access non-static variables. However, addPrice is a static method and applePrice variable of Apple class is also static. Why then we needed to use Apple.applePrice to access the variable in addPrice method?
