5 Courses to Improve Email Writing for Programmers, IT Professionals, and Software Engineers

One of my readers emailed me a couple of days ago and asked If I could suggest something to improve his email writing skills? He says that he is very good at work and programming but sucks on writing emails and because of that he never gets the visibility he deserved, resulting in no promotion or career growth. This sounds me a very common problem, especially among programmers whose native language is not English, and who have never attended any business or email writing course. In fact, it was a problem with me as well but I slowly picked it up though I am still far behind with many people I know who have excellent email communication skills.

How to implement Binary Search in Java without Recursion - Iterative algorithm

This week’s task is to implement a binary search in Java, you need to write both iterative and recursive binary search algorithm. In computer science, a binary search or half-interval search is a divide and conquer algorithm which locates the position of an item in a sorted array. Binary search works by comparing an input value to the middle element of the array. The comparison determines whether the element equals the input, less than the input or greater. When the element being compared to equals the input the search stops and typically returns the position of the element. If the element is not equal to the input then a comparison is made to determine whether the input is less than or greater than the element.

Top 5 Object Oriented Programming and Design Courses in Java - Best of Lot

There is no doubt that Object-oriented programming is a pillar of software development and also one of the reasons for the huge success of Java. Good knowledge of Object-oriented programming helps you to create better software. It also helps you to communicate your ideas better with your team members and fellow programmers. Despite being such an important technology, it's difficult to find programmers who understand OOP well. Many programmers just think that OOP is nothing more than Abstraction, Inheritance, Encapsulation, and Polymorphism, without truly understanding these concepts and mastering them.

Is "Java Concurrency in Practice" Still Valid in the Era of Java 8 and 11?

One of my reader Shobhit asked this question on my blog post about 12 must-reads advanced Java books for intermediate programmers - part1. I really like the question and thought that many Java programmers might have the same doubt whenever someone recommends them to read Java Concurrency in Practice. When this book came first in 2006, Java world was still not sure of about new concurrency changes made in Java 1.5, I think the first big attempt to improve Java's built-in support for multi-threading and concurrency. Many Java programmers were even not aware of new tools introduced in the API e.g. CountDownLatch, CyclicBarrier, ConcurrentHashMap and much more. The book offered them the seamless introduction of those tools and how they can use them to write high-performance concurrent Java applications.

Thread, Code and Data - How a Multithreading Java Program Actually Run

There are certain things, which you don't learn on academics or training class, you develop those understanding after few years of work experience, and then you realize, it was very basic, how come I had missed that all those years. Understanding of how a multi-threaded Java program executes is one of such things. You definitely have heard about threads, how to start a thread, how to stop a thread, definitions like its independent path of execution, all funky libraries to deal with inter-thread communication, yet when it comes to debugging a multithreaded Java program, you struggle.

Difference between @ContextConfiguration and @SpringApplicationConfiguration in Spring Boot Integration Test

Even though both @ContextConfiguration and @SpringApplicationConfiguration annotations are used along with SpringJUnit4ClassRunner to specify how to load the Spring application context, there is a subtle difference between them. Although @ContextConfiguration does a great job in loading application context it doesn't take full advantage of Spring Boot features. Spring Boot applications are ultimately loaded by either SpringApplication ( in case of the JAR) or SpringBootServletInitializer. This class not only loads the application context but also enables logging and loading of external properties specified in application.properties or application.yml file, and other features of Spring Boot framework, which is not loaded or enabled by the @ContextConfiguration annotation.
