Like with lambdas, the syntax can take a bit of practice to get used to, but once you have got used to it, streams allow you to write nice, concise code. And being able to read and understand streams with lambdas is really important because a lot of Java code that's been written since Java 8 uses this syntax. So let's think about an example of where streams might be used.
