What is the best way to filter a Java Collection?

Question

I want to filter a java.util.Collection based on a predicate.

Answer 1

Using java 8, specifically lambda expression, you can do it simply like the below example:

myProducts.stream().filter(prod -> prod.price>10).collect(Collectors.toList())

where for each product inside myProducts collection, if prod.price>10, then add this product to the new filtered list.
