failing private test case for level 5 about 2122-s2

[jace-han]

Hello! The ArrayIndexOutOfBounds exception is raised as you are trying to access the first element ("Index 0 out of bounds") when the list is empty ("for length 0"). I can't really help for the loaders (marked by red boxes) just from expected and your output though.

Hi! I ran into the same error as you, you may want to check if your code still runs normally for an empty cruise list

I ran into the same error too so I just added a check for an empty cruise list before running code for level5

One of the private test cases includes running an empty cruise list to the method. So your code must take into account of that!!

To the comments above: If one is running a for loop iterating through the cruise list to "get" the cruises, would an empty cruise list throw an ArrayIndexOutOfBounds error? To my understanding, I don't think so because the for loop would just not be executed. Unless the iterator was set to <= list.size()

Yeah, the for loop is not executed, as it will immediately meet the condition < list.size().

It is specified the JLS:
https://docs.oracle.com/javase/specs/jls/se8/html/jls-14.html#jls-14.14.1.1

If the (possibly unboxed) value of the Expression is false the first time it is evaluated, then the Statement is not executed.

Hey, the error you're experiencing is most likely happening because it is looping through an empty iterable. For my code, I actually implemented an if-else that if the iterable is empty, it will add something into it first before iterating through the iterable. Alternatively, you could use a do-while loop. Hope this helps.

Codecrunch has a test case to check if the list is empty. Hence do check if the list is empty before looping through it. Using a while loop condition will make your code more elegant as compared to for loops.
