How to interpret the syntactic construction?

Question

Java

Good afternoon!
I am reading the book "Java 8. Beginner's Guide"
Perhaps because I read selectively, or maybe not, but I can not understand the following syntactic construction

ЬtnUp.setOnAction(new EventHandler<ActionEvent>()

puЬlic void handle(ActionEvent ае) {

response.setText("You pressed Up.");

}
}) ;

And specifically, what is this "<"ActionEvent">" in such brackets.
Google about anonymous classes, but there is no such thing.
Only comes across

public class Anonymous {
   public static void main(String[] args) {
    Runnable anonym = new Runnable() {
      public void run() {
      }
    };
  }
}
