It allows us to specify which classes or interfaces are allowed to extend or implement a
Java 8 Features Java 8 Core Java java by devs5003 - August 20, 2023March 18, 20243 Java 8 was released by Oracle after 2 Years 7 Months 18 Days of release of java 7 on March 18th, 2014. However, after Java 1.5 version, Java 8 is the next major release version. Before Java 8, Sun community focused majorly on objects, but in Java 8 version, Oracle community has focused more on functional programming to bring its benefits to the Java language. However, it doesn’t mean that Java is a functional oriented programming language, but we should grasp it in a way that we can apply functional aspects of programming as well now with Java 8. It is a part of Java 8, as an object oriented programming. Here, we will discuss new Java 8 Features one by
Stream API in Java 8 java Core Java Stream API by devs5003 - August 11, 2023March 18, 20243 Data Processing is the dominant part of a Software Application. As a developer, we can't think of developing an application without data processing logics. However, almost every Java Application uses the Collections API to store and process data. Using Collections API, it is not so easy to write the codes for even some common data processing operations such as filtering, sorting, matching, finding, mapping etc. That's why Java API designers have come up with Stream API in Java 8 to implement more complex data processing logics with the least number of lines of code. So, in this article, we are going to learn Stream API in Java 8 and how to work with the complex data processing operations in an easy
