Let’s be honest: It’s pretty exciting that Infinispan now supports Java 8 for many reasons, but perhaps one of the most anticipated reasons is because of the new stream classes. The main reason for this is the fact that it completely transforms the way we process data. Instead of having to iterate upon the data yourself, the underlying stream does this for you, and all you have to do is provide the operations to perform on it. This is perfect for distributed processing because the implementation handles the iteration entirely.
However, another important reason why these kinds of advancements are so important is they make development accessible to younger generations. By creating easier methods, we are actually opening up opportunities for young people to get involved in the tech sector, and creating career paths for people who have earned an information technology degree that feel as though this work may be too hard for them.
To gather insights on the state of the Java ecosystem today, we spoke to nine executives who are familiar with the ecosystem.
We asked these experienced Java professionals "What do developers need to keep in mind when working with Java?" Here's what they told us:
The purpose of any version control system is to record changes to your code. This gives you the power to go back into your project history to see who contributed what, figure out where bugs were introduced, and revert problematic changes. But, having all of this history available is useless if you don’t know how to navigate it. That’s where the git log command comes in.
By now, you should already know the basic git log command for displaying commits. But, you can alter this output by passing many different parameters to git log.
As a typical nerd (and a DZone Zone Leader), I tend to read a lot of blog posts and comments about programming. One thing that keeps amazing me is how long people’s functions tend to be and how many people are convinced this is the right way to code. In reality, a readable function should rarely exceed five lines of code.
Take a short look at this function:
Scheduling tasks to run is a need that sometimes arises in a Java program. Maybe you want to run a periodic cleanup of some resource, or check on the status of some job, or maybe fetch a URL which might not be available the first time.
The Timer class provides a very simple implementation of such a scheduler. Let us learn how to use it.
