How to use filter + map + collect + Stream in Java? Example Tutorial

Hello guys, many of my readers emailed me to write a post about the map and filter function of Java 8 because they found it difficult to understand and use. Even though I have previously blogged about both map() and filter(), I am writing this post again to explain the concept in more layman's language for a better understanding of my readers and fellow Java developers. The map() function is a method in Stream class that represents a functional programming concept. In simple words, the map() is used to transform one object into another by applying a function. That's the reason the Stream.map(Function mapper) takes a function as an argument. For example, by using map() function, you can convert a list of String into List of Integer by applying Integer.valueOf() method to each String on the input list.

He then asked me if I can write an article about it. I said you should have read the Java concurrency in Practice book or join the Java Concurrency in Practice Bundle course by Heinz Kabutz before the interview, that would have helped, but nonetheless, I liked the idea to just provide a quick overview of what is the happens-before relationship between threads in Java.

10 Difference between StringBuffer and StringBuilder in Java? [Answered]

What is @SpringBootTest annotation in Spring Boot? When and How to use it? Example Tutorial

Hello guys, if you want to learn what is @SpringBootTest and how to use this annotation to test your Spring Boot application then you have come to the right place. Earlier, I have shared the best Spring Boot courses and Spring Boot Testing interview questions and in this article, I am going to explain to you about @SpringBootTest annotation. Before diving into how to use @SpringBootTest annotation. It is good to briefly introduce Testing in Spring boot. There is unit testing and integration test. In a nutshell, when you do a unit test, you only test just a single unit of code, one method at a time, excluding all other components. Other components you exclude would be tested separately and that is another unit test. On the other hand, the Integration test is bringing all the unit tests together making them work without breaking any units of codes. A particular unit of code can of course work on its own.
