Java can finally join strings

I am sure you were in a situation in which you wanted to join multiple strings. If you were using a programming language other than Java you probably used the join() function provided by the programming language. If you were using Java you could not do this. There was no join() method. The Java Standard Class Library provided you tools ...

The Programmer Productivity Paradox

Programmers seem to be fairly productive people. You always see them typing at their desks; they chafe for meetings to finish so that they can go back to their desks and code. When asked, they will say that there is not enough time to produce the code, and the sooner they can start coding, the sooner they will be done. ...

How HashMap works in java

Most common interview questions are “How HashMap works in java”, “How get and put method of HashMap work internally”. Here I am trying to explain internal functionality with an easy example.

The Microservice Architecture Sounds Like Service-Oriented Architecture

I didn’t understand the service-oriented architecture. I thought that it was just one of those highly theoretical and very impractical software architecture patterns. In other words, I considered it to be an architecture fanatics’ wet dream. Then I read an article titled Microservices by Martin Fowler, and the service-oriented architecture started suddenly make sense to me. What Changed My Mind? ...

The Cloud my friends, is nothing but the Internet. Different vendors  set up the Infrastructure, Platform and Software and make them available to us from remote locations over ...

Empathy in OSS – It’s Important

Spending nearly my entire working day (and many evenings) with Open Source projects I don’t maintain I have come to form an opinion or two on the use of OSS – specifically when it comes to contributing to projects. We’ve come a long way as a community with tools like Github, making it easier and easier to get an OSS ...

A SQL query DSL for Scala by ScalikeJDBC

There are a tremendous amount of SQL APIs natively written in Scala. Manuel Bernhardt has summarised a nice collection in his a post. Another collection of Scala SQL APIs can be seen in this Stack Overflow question. One API that we want to focus on in particular is ScalikeJDBC (licensed ASL 2.0), which has recently published a SQL query DSL ...

Java EE 7: What’s new???

java-interview-questions-answers

I am a little ‘late to the party’ so to say… as far as ‘blogging’ about Java EE 7 is concerned. It has almost been 10 odd months since it was released back in June 2013, but it is still relatively new. Personally speaking, I am thrilled about it, simply because of the ease-of-use and the gamut of features it has bought ...

Afraid of reopened issues?
