Join Peggy Fisher for an in-depth discussion in this video Solution: College cost app, part of Java Essential Training for Students.
- This challenge was meant to refresh your skills in working…with various data types and working with methods.…Let's take a look at my solution,…and remember, your solution might be very different.…At the top of my solution, I have my main method.…Inside the main method, I only call two methods,…just like before.…I have in line 32, String name = getName();…and then 33, I have printTotal() and I pass…the name of the student to the printTotal() method.…Let's scroll down a little bit.…
In the printTotal() method, I have a parameter…that brings in the name as a string.…Then, I check to see if the student is on campus…by calling the onCampus() method,…which returns a Boolean variable of true…if they're on campus or false if they're not.…On line 46, you can see I'm actually calling…several methods within the statement that says…total = calculcateTotal() expenses and I give it…the estimatedLivingExpenses(), the booksAndSupplies(),…the creditHours(), and the costPerCredit() hour.…
If the student is not on campus, then I don't need…
