A functional interface is an interface with only one abstract method. I would like to talk to you about the various categories of functional interfaces most used and known. […]
Java 8 categories of functional interfaces
BE based
In the category BE based you will be able to find everything that lies behind the lines, which directs what the user will then see and interact with. Typing is king and the speed of information transfer is the ultimate goal of a good BE. To achieve this end, mapping and polymorphism, error handling and security come into play.
Java 8 Lambda expressions and functional interfaces
To talk about lambda functions and functional programming we must first talk about functional interfaces. A functional interface is an interface with one and only one abstract method. They have a special relationship with lambda expressions.From Java 8 we can find many functional interfaces in java.util.function package. A functional interface […]
ModelMapper for simple mapping of objects
Today we will see how to implement a ModelMapper that allows us, for example, to transform an object with many properties into a smaller object with fewer properties. This transformation can be useful for example when we need leaner objects, perhaps in a list, or when we want to expose […]
Java Streams
Java streams are sequences of data elements that can be processed with operations. Streams consist of 3 parts: a source, zero or more intermediate operations, and a terminal operation.In the meanwhile there is a data in pipe, another data is waiting its turn. For instance, for a data in terminal […]
Java generic types
Let’s talk about the Java generic types. Most of the time, we add generics to make lists type-safe.We have pre-java 5 lists without generics that can get all known object’s types and when you get an object out of it we don’t know its type. When we use generics we […]
