Learn Java: Getting your hands dirty with this language!


earning java can give you headaches if you are a beginner. Why? Because before starting to learn Java programming, you need to prepare your machine. You need to install everything you need for java programming, making it suitable for coding in Java language.  But don’t you worry…we will arm you with all the tools you need to get started, including this renowned Ultimate Java Tutorial for Beginners.

First off, some introductions. Java is a high-level, object-oriented programming language developed by Sun Microsystems. Learning Java has its incentives, as it’s a powerful language for developing desktop applications, web applications, and many smart devices run on Java. Java is also a platform-independent programming language, highly portable. If your computer runs on Windows, Linux or Mac OS, they all are same for Java because it runs on virtual machine.

So, first things first – before writing your first code in Java, you need to install what is called as Java virtual machine (JVM), also known as Java Runtime Environment (JRE). JRE can be downloaded from this link:

http://java.com/en/download/index.jsp

One that’s complete, you will have JVM installed on your PC. That allows Java programme to run on your machine. To write and test the Java codes, you need to install Java’s software development kit (JDK). The JDK can be downloaded from this link:

http://www.oracle.com/technetwork/java/javase/downloads/index.html

Here, you have a bewildering list of options to download from. Look for Java SE (Standard Edition). One of the links on this webpage will enable you to download JDK and NetBeans. More explanation on NetBeans in a bit. Install the JDK on your machine, and be sure that you are downloading all the software appropriate to your Operating System. You should be clear about whether you have a 32-bit or a 64-bit OS.

What’s the next step? How do you compile and run a Java programme?

Before moving on to the next step i.e., IDEs, let’s talk about some nitty-gritties of how Java programme works. You always start writing codes in a text editor (you will find in-built text editors with IDEs: NetBeans, Eclipse, or Jcreator), called the source code which is saved with a file extension .java. The java compiler (Javac) turns the source code into a class file with extension .class. Once you have the class file, it can be run on JVM. Now to make this process hassle free, IDEs come to rescue.

Now, what’s the next step in java learning?

Let’s get your hands dirty with this IDE thing. The IDEs (Interface Development Environment) take care of all the creating and compiling of jobs for you behind the scenes. They takes your code, create the java file, launch compiler to arrive at class file, and let you run your programme. Here is a list of some quality IDEs like:

Eclipse – a free, popular program. (Learn Java Programming Using Eclipse)
Netbeans – another free program; it is open source and available in many languages.
Jcreator – A for-pay program that provides a bit more power than most other IDEs.[Source]-https://www.udemy.com/blog/learn-java/

Why, when and how to return Stream from your Java API instead of a collection

Introduction Collections are basic and commonly used data structures. Programmers from the beginning of their career learn how to use them to receive, process and return data. Getting more advanced in Java programming, they find stream() method to convert a collection into a stream and learn how to process data using some of the stream’s useful methods like map, flatMap or reduce. They could also notice that other APIs in Java return a stream too e.g. String.lines(), Matcher.results(), Files.find(), Random.ints(). If you have experience with consuming streams but haven’t produced them yet, this article is for you. I’m going to show you some scenarios where streams can be very convenient and examples on how to use them. Additionally, I shortly mention error handling and resource management. The article is based on standard Java library java.util.stream. It’s related neither to reactive streams nor to other implementation of streams like e.g. Vavr. Also, I’m not going to cover a...

What is Kubernetes?

Kubernetes (also known as k8s or “kube”) is an open source container orchestration platform that automates many of the manual processes involved in deploying, managing, and scaling containerized applications. In other words, you can cluster together groups of hosts running Linux containers, and Kubernetes helps you easily and efficiently manage those clusters. Kubernetes clusters can span hosts across on-premise, public, private, or hybrid clouds. For this reason, Kubernetes is an ideal platform for hosting cloud-native applications that require rapid scaling, like real-time data streaming through Apache Kafka. Kubernetes was originally developed and designed by engineers at Google. Google was one of the early contributors to Linux container technology and has talked publicly about how everything at Google runs in containers. (This is the technology behind Google’s cloud services.) Google generates more than 2 billion container deployments a week, all powered by its ...

Best way to learn Java programming

Having said that I am writing this post dedicated to all my young (or I should say beginner) fellows who want to attain a certain level of proficiency in java technology and somewhere would like to take my advice on this. Keep in mind that if you do not like the way to learn java, I am proposing in this post, then just ignore me. Period. OR better, suggest me what you think is the better way to learn java fast or easily. Here I am assuming the people reading this post will be, who are very new to language, so I will start by listing first thing first. Make sure you have prepared your Java development environment ready i.e. You have installed JDK/JRE and you have an IDE like Eclipse. 1) Learn the language basics This is the first step for very obvious reason. If you don’t know the basics then you will never know either what to do next or what you are doing wrong. Initially, I do not expect from you to become the master of all java basic stuffs like keywords, core concepts o...
