I have a really quick question if anyone does not mind answering, the first sentence on the MySet paragraph: NOTE: Java has a built in Set class. You may NOT use this class or any of its methods. Also, you may not use any of the built in Java Collection classes inside of your MySet class. This means no ArrayLists, Lists, Maps, etc. Does this mean we can not import an array utility? (import java.util.Arrays;) Thank you for taking the time to read this message. |

I believe John upholds his directions, therefore, I'd say you can't use anything that is inside the Java Collection classes found here: [https://docs.oracle.com/javase/7/docs/api/java/util/Collections.html]. I am taking his instructions directly and not including any methods from any of the classes he specifies, everything else (to me) is free game. This is the way I've been coding in his class and he hasn't said anything yet, just remember to comment that you understand something that isn't taught in the class before you use it.
TLDR: No usage of anything inside Set Class [https://docs.oracle.com/javase/7/docs/api/java/util/Set.html] or Java Collection [https://docs.oracle.com/javase/7/docs/api/java/util/Collections.html]. Last edited by nickdrakesi at

I will make one exception: you can use Array.sort() in your .equals() method |

So you are saying, we are able to useArray.sort() in order to display the matching integers, sorted into an order we determine? |

Yes, because this will make the equals() method much easier |

Does this mean I can not use Arrays.copyOf to copy the array without duplicates and create the new array? |
