This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
My teacher has asked us to take the following class file, Date.java:
...and create 2 private date fields, as I have already done:
He then wants us to create two constructors: one as a default constructor, and the other that accepts the start and end dates of the time period as parameters. The problem is, I don't know how I would go about creating these methods.
I have tried:
...but I get an error saying that it must return something. Maybe I'm going about this completely wrong, anyways. Could someone please shed some light on this?
The class is named Date, so the constructor must also be named Date, not DateSpan. If you call it "DateSpan" then Java thinks it's a method instead of a constructor, and in a method declaration you always need to specify a return type ("void" if the method doesn't return a value).
