> I want to iterate over the ArrayBuffer. You should get yourself familiar with methods related to the Scala collection library: https://twitter.github.io/scala_school/collections.html
Almost all of the methods take a function as their parameter. This is a very convenient feature of Scala (unlike in Java, where you have to get an iterator, the use the iterator.hasNext and .next). For an example, you can write like: ArrayBuffer(5,3,1,4).foreach(println) It's because "foreach" expects a one-parameter function as its parameter, and "println" is such a function.
