In this article I will try to explain the issue of Lambda expressions available in Java. Lambda expressions shorten the code, making it more readable. This may seem like a small advantage and all the hype surrounding this element of the Java language is exaggerated. Fortunately, the improvement in code readability is very large. In short, instead of creating a new Java class (new file) that consists of eight lines of code, we can create a one-line Lambda expression that will do the same as a separate class, plus we have all the code in one place - no need to navigate after classes. Lambda expressions show their full potential when combined with Java Streams.<\/p>\n\n\n\n
I will divide the article into two sections, each section will consist of three steps showing the transition and transformation of the code into Lambda expressions. Finally, I present a practical application of Lambda expressions with Java Streams - Processing Data with Java SE 8 Streams<\/a>. When we already know the Lambda expressions, we do not have to go through the entire process, step by step, the last form from point Simple Lambda expression - anonymous implementation of an interface method<\/a>. Creating Lambda expressions in the steps described in this article are for educational purposes.<\/p>\n\n\n
