They are now a commonly used feature in the Java language so it is useful to be able to read and understand them, as well as to use them in your own code. In this example I have a functional interface called greeting message which has a single abstract method called greet, then in my main class, I implement a new greeting message instance using an anonymous inner class. I override the greet message followed by the name parsed in. Instead of using all this boiler plate code, I can use a lambda instead to make the code shorter and simpler, so in the main method below the code I already have. I will create a second greeting message variable and I will call it gm2 and then put the equals sign.
