Time to learn about disjoint().

Same data. Different look.

Sometimes you need a List. Sometimes you need an array.

Need to sort elements in a Stream sequence? That's the easiest thing in the world to do.

Need to trim the fat from your List? Gotta get rid of some unwanted duplicate elements? If so, then have a look at the distinct() method on Stream.

Raw data doesn't do management any good. They need the numbers transformed into something readable and meaningful.

Sometimes you end up with a List object that you need to whittle down to fewer elements. One way you can do that is with a Java Stream and the filter() method.

If you want to take a look a small sample of objects in a Stream sequence, feel free to use the limit() method.

Need to turn your monstrously large Java Stream into a paginated List? If so, I've got you covered.

Want to know if any object in your list matches a specific criteria? If so, then turn that List into a Stream and use anyMatch().
