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

Java Coding Best Practices and Standards java Core Java by devs5003 - May 18, 2023April 21, 20240 As a developer, while doing coding task, there is a probability that we make some mistakes accidentally. Sometimes, the compiler catches the mistakes and warns us to correct it. But when we make a mistake and compiler didn't catch it, we may face an issue after running the program. That's why we should have some elementary knowledge of Java Coding Best Practices and Standards in order to avoid them. These Java Coding Best Practices and Standards are not only useful in writing a successful program, but also in improving the performance of the application in the long term as a whole. Based on the Code Review, we are going to mention a synopsis of the common mistakes that a Programmer commits.
