The difference is how you can call this function. The array variant can only be called with an array

isAscOrder(new int[] {1, 2, 3});

while the varargs variant can be called with an array or with separate arguments

isAscOrder(1, 2, 3);

and the java compiler will create the array for you under the hood.

Thank you for the most helpful comment. You must be a god in development.

I agree that this is cheating even though I have the same solution.LOL

I wouldn't, to be honest. Technically it could be useful if you still need the side effects of case1 and case2 or something, which you wouldn't always get from case2 if condition else case1, but there are less confusing ways to write that.

Yes
