Java

Owned by the Oracle Corporation, Java is one of the oldest, most typical, in-demand programming languages in use these days. Well, think about a number of your favorite internet apps and games. It’s extremely probably that Java plays an enormous role within the code that creates their work. Another necessary factor that has kept Java’s magic intact among internet development corporations is its independence from platforms. This helps developers to basically “write once, work anywhere”(WORA). Java is everyplace and also the demand for sturdy developers is virtually high.

How does it work?

In Java, programs don’t seem to be compiled into practicable files; they’re compiled into bytecode (as mentioned earlier), that the JVM (Java Virtual Machine) then executes at runtime. Java source code is compiled into bytecode after we use the javac compiler. The bytecode gets saved on the disk with the file extension.

Reasons for Demand:

  • With its presence in almost 3 billion devices, Java’s new frameworks such as Spring, Struts, and Hibernate have also become very popular.
  • It is favored by enterprises, with roughly 90 percent of Fortune 500 companies use Java for building applications and back-end systems.

How does it work?

TypeScript works by adding increased syntax to JavaScript so transforming it to JavaScript when the typescript compiler will its own checks. It does not modification JavaScript’s kind of system. Instead, it adds a lot of checks to it.

Reasons for Demand:

  • TypeScript simplifies JavaScript code, making it easier to read and debug.
  • TypeScript gives us all the benefits of ES6 (ECMAScript 6), plus more productivity.
  • TypeScript can help us to avoid painful bugs that developers commonly run into when writing JavaScript by type checking the code.
  • TypeScript is a modern programming language loved by engineers for making web development a lot easier.
  • You can use TypeScript everywhere instead of JavaScript, as it compiles to regular JS code. That’s another reason for its demand.

Scala

Scala could be a programming language used for practical programming and powerful static systems. It’s object-oriented and runs on JVM. It’s the aptitude to interoperate with existing Java code and libraries. It’s powerfully thought of to be a static kind of language and doesn’t have an idea of primitive information.

How does it work?

The compiler in Scala works during a similar fashion because of the Java compiler. It gets the source code and generates Java byte-code which will be dead severally on any commonplace JVM (Java Virtual Machine). Scala could be a statically typed language. Scala will execute Java.

Reasons for Demand:

  • Scala programming language variables are immutable and can be easily overloaded in Java. In addition to this, it also offers to adopt new languages like Python, Ruby, etc. to implement functional programming.

Technology is always evolving, and if you want to make a career for the future, is the way to go Blockchain.

What is Blockchain Developer?

Blockchain developer skills are a combination of hard skills and soft skills from an abstract point of view. They can handle the entire life cycle of a blockchain application. This means that you will be responsible for the execution of the application as well as research.

Types of Blockchain Developers:

There are two types of Blockchain Developer.

  • Blockchain software developer
  • Core blockchain developer

They are both involved in blockchain development, but they have different responsibilities.

Blockchain Software Developer

Blokchain software developers to create applications based on Blokchain architectures and protocols. Their apps also run on the blockchain. You can compare them to web developers, who use the products of a web architect (protocol and design) to develop web applications.

Blockchain software developers create dapps or decentralized applications. They are responsible for the back-end development as well as front-end of Daps. They also monitor the stack running the dapps.

Core Blockchain Developer

These developers focus on the architecture development of blockchain systems. They design their own consensus protocol and make most of the important decisions related to the blockchain. They monitor the network and design the architecture of the same. Core blockchain developers are also responsible for the security of their blockchain network.

Role and Responsibilities of Blockchain Developer:

  • Research, design, develop, and test blockchain technologies.
  • Brainstorm and help evaluate applications for new tools and technologies as they continually evolve.
  • Maintain and extend current client- and server-side applications responsible for integration and business logic.
  • Collaborating with managers to determine blockchain technology needs and envisaged functionalities.
  • Maintaining client and server-side applications.
  • Optimizing and securing blockchain applications by integrating new tools and technologies.
  • Taking into account the current blockchain technologies and cryptography methods.

Blockchain Developer Skills:

Blockchain developers have many responsibilities. To handle those responsibilities well, they must possess certain skills as well.

Cryptography:

Cryptography is the study of protocols that prevent unwanted parties from accessing your data. There are several essential concepts in cryptography that you should be familiar with as you will need them during blockchain development.

Data Structures:

To become a blockchain developer you need to have extensive knowledge of data structures. This is because blockchain developers regularly work with different data structures as they need to build and implement networks.

Blockchain Architecture:

To become a blockchain developer, you must be familiar with blockchain architecture. You should know what a ledger means in a blockchain, what is consensus, and how smart contracts work.

Web Development:

As a blockchain developer, you will be developing web apps in most cases. Learning web development will you familiar with all its aspects, and you can create robust web apps that use Blokchain technology using this knowledge.

Java:

Java is popular among blockchain developers due to its many properties. It is easy to learn, but it is capable of developing many complex solutions.

C++:

C++ is a popular language among blockchain developers. You can do a lot of things related to blockchain with its help. The creators used C++ to create Bitcoin Core, so it’s definitely a must-see for any aspiring blockchain developer.

Python:

Python is one of the most popular programming languages on the planet. It is versatile, and its various libraries enable you to use it for both front-end as well as back-end development. So you should also familiar yourself with Python.

You can learn JavaScript, Ruby, and C# in addition to the languages mentioned above. The ability to learn and work with multiple languages is one of the important blockchain developer skills.

What Blockchain Developer do?

Blockchain software developers build applications based on the blockchain architecture and protocol. Blockchain software developers create dapps or decentralized applications. They are responsible for the front-end as well as back-end development of Dapps. They also monitor the stack running the dapps.

Blockchain developers enable secure digital transactions by the system to record and store Blockchain data which prevents changes or hack.

  • They design secure blockchain technologies.
  • Develop application features and interfaces.
  • Maintain client and server-side applications.

At present, Blockchain is considered one of the most revolutionary technologies as it transforms the way we interact, transact, and share information. Many technocrats and Blockchain Experts also believe that it is going to be the most disruptive technology in the next decade.

Today, this technology is not only used by tech giants, enterprises, federal agencies, and even startups have started adopting Blockchain. In fact, they are looking for Certified Blockchain Experts and are considering certified professionals over the non-credential peers.

Apache Ant

Ant is a Java library and command-line tool. Ant’s mission is to drive processes described in build files as targets and extension points dependent upon each other. The main known usage of Ant is the build of Java applications. Ant supplies a number of built-in tasks allowing to compile, assemble, test and run Java applications. Ant can also be used effectively to build non Java applications, for instance C or C++ applications. More generally, Ant can be used to pilot any type of process which can be described in terms of targets and tasks.

Ant is written in Java. Users of Ant can develop their own “antlibs” containing Ant tasks and types, and are offered a large number of ready-made commercial or open-source “antlibs”.

Ant is extremely flexible and does not impose coding conventions or directory layouts to the Java projects which adopt it as a build tool.

Software development projects looking for a solution combining build tool and dependency management can use Ant in combination with Ivy.

Introduction of Apache Ant

Apache Ant is a software tool for automating software build processes. It is similar to Make but is implemented using the Java language, requires the Java platform, and is best suited to building Java projects.

The most immediately noticeable difference between Ant and Make is that Ant uses XML to describe the build process and its dependencies, whereas Make has its Makefile format. By default the XML file is named build.xml.

Ant is an Apache project. It is open source software, and is released under the Apache Software License.

Apache Ant: A Build Tool

Apache Ant (or simply Ant) is an XML-based build scripting language used heavily by the Open Source community. Ant automates tasks such as compiling source code, building deployment packages and automatically checking dependencies of what items need to be updated in a build set.

Using Ant to build J2EE Applications

Apache Ant (Another Neat Tool) is a build tool, mainly for Java projects. A build tool can be used to automate certain repetitive tasks, e.g. compiling source code, running software tests, creating jar files, javadocs, etc.

A build process typically includes:

  • the compilation of the Java source code into Java bytecode
  • creation of the .jar file for the distribution of the code
  • creation of the Javadoc documentation

Ant uses a xml file for its configuration. This file is usually called “build.xml”. Within this build file you specify the targets for ant. A target is a step which ant will perform. You also can specific dependencies. If target A depends on target B, ant will first do B and then A. Also you specify the main target. This target is the target ant will try to execute per default. If this target depends on other targets then ant will automatically perform these task first and so on and so on.
