Avoid using stream for simple iteration

Let’s say we have a collection; it could be a list or set, it doesn’t really matter as long as it is a collection, and we want to iterate over it. Often, we make this mistake: we immediately open stream whenever we think of working with a collection; since java 8, it has, sort of, become our second nature, which is excellent. Hurray!

However, I have seen this in many production codes. Well, the outcome indeed serves our purpose, but it may not be necessary to open a stream. All the collection interface has a for each method in them, and it does the same thing we are supposed to do here. However, creating a stream creates a new object that is just needed to get our desired output.
