How Linear Search or Sequential Search Algorithms works in Java? Example Tutorial

Hello guys, earlier, I have talked about how the binary search algorithm works and shared the code to implement the binary search in Java. In that article, someone asked me about is there any other search algorithm exists? How can you search an element in the array if it's not sorted, and you cannot use the binary search algorithm? To answer his questions, I mentioned about the Linear search algorithm, which is the predecessor of binary search. Generally, it is taught before the binary search algorithm because the binary search is faster than Linear search. However, nevermind, you can still learn this useful algorithm to search an item in the array or linked list.

What is happens-before in Java Concurrency? An example

A couple of days ago, one of my readers messaged me on LinkedIn about a Java interview question he has recently faced - what is the happens-before relationship in Java concurrency? What is the benefit of it, and how exactly it works? He kind of has some ideas about that its related to the Java Memory Model and provides some sort of visibility guaranteed but couldn't explain with conviction to his interviewer, particularly with a code example and was a bit disappointed. He then asked me if I can write an article about it. I said you should have read the Java concurrency in Practice book 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.

I have read somewhere that programmers should learn a new programming language every year ( I think it's code complete, not sure, though), but if you cannot do so, I suggest to at least learn the following five programming languages to do well in your career.

I personally like Software Engineers who have substantial experience in either C++ or Java and can write scripts in Groovy, Perl, or Python.
