Transcript

Hi there. In this section, we learned what a marker interface is, what a functional interface is and lambda expressions. In addition, we learned the predicate interface which is widely used and makes our work very easy in large scale projects and how to use this interface with Lambda. Finally, we touched on the concept of static import. Since Lambda expression is new to Java, it may seem a little confusing to you, but the more you use it the better you will understand how neatly and simply it allows us to write our code. 

There's also a lesson in the object-oriented section where we explain the use of Lambda's in the simplest form. If you came to this section without watching that lecture, please watch that lecture first because we explained the use of lambda in a similar way there. In this section, we went one step further and developed the calculator project we developed earlier by using the lambda expression. Therefore, if you only watched this section, it might seem a bit complicated to you. After remembering this, we can end this section. See you in the next lesson.
