Java is based on OOPS concepts and abstraction is one of its feature. So by using interfaces in Java, we achieve abstraction. Like a class, an interface can have methods and variables, but the methods declared in an interface are by default abstract (method signature without body).
First, let’s have a basic understanding of stream. Then we will have a look at the side effects that can occur while working with streams. Streams represent a sequence of objects from a source, which supports aggregate operations. One thing to be notified while working with streams is that, aggregate operation (intermediate operations) are lazy evaluated i.e. they do not start processing the content of Continue Reading
The Functional Features of Java8 Java 8 was a major release in terms of language and APIs. The language includes several ideas from functional programming like behavior parameterization, passing lambda expression as methods, processing data with stream pipelines etc. The following presentation describes the functional programming add on in Java 8. We will be introducing the lambda expression, Functional Interfaces, Default methods and Stream API in Java Continue Reading
