6 Skills Java Programmers Must Acquire In 2021
Technology is evolving at a rapid pace. With the latest changes come the upgraded versions of the programming language and framework, be it Java, Python, or the C language.
Over the last couple of years, Java came with many updates – Spring 5, Spring Security 5, Spring Boot 2, and other exciting features such as API enhancements, Records, GC improvement, var with local variables, and many more.
No doubt these continuous upgrades get overwhelming for the programmers to stay up to date, but at the same time, embracing new enhancements and refining Java programming skills can help you stay on par with the latest market demands and new opportunities.
This is one reason why more and more students and budding developers take up advanced Java programming courses and seek Java assignment help. They can learn, upgrade skills, or develop advanced academic tools such as a plagiarism checker, citation maker, or essay maker.
That’s why; today, we will discuss six advanced skills a Java programmer must learn in 2021.
6 Advanced Skills Every Java Programmer Should Hone
- DevOps (Jenkins)
Jenkins is the open-source server for developers to build, test, and deploy software. It allows developers to integrate a large number of changes and deployment technologies. In addition, Jenkins manages the continuous integration and continuous delivery (CI/CD) pipeline to support various activities.
Jenkins is vast, and it can take years for developers to learn about tools and principles. However, it is a must-know skill for developers as most organisations have adopted CI and CD, improving the software development process.
Learning Spring is not an option but a must-have skill for aspiring Java programmers. It is an open-source framework supporting other frameworks such as EJB, Hibernate, Tapestry, Struts, etc., and helps developers create advanced applications with old Java programming models.
Spring allows developers to add pluggable transaction managers easily and demarcate transactions. Also, since it is not limited to J2EE environments, developers can use it in container less environments.
- Spring Boot
Spring Boot is another Java skill developers must learn for the smooth development of Java applications. It simplifies the developer’s work by removing boilerplate codes and creating a more accessible and efficient development ecosystem with minimal configuration.
Spring Boot saves your time and has most of the work cut out for you, as it auto-configures everything you need for the project. As a result, it cuts down the time you need bootstrapping the Java projects and simplifies application configuration.
Maven is a crucial skill Java programmers must have for project creation, dependency, and documentation using plugins and Project Object Model. This automation and management tool is far more advanced than ANT and can build countless projects in the required output.
With Maven, developers can efficiently build Java-based projects, increase project performance, and improve the building process. Eclipse, NetBeans, and MyEclipse are a few of the well-known IDEs for development with Maven Framework.
- Git & GitHub
Git is a free and popular open-source control system designed to handle all projects with efficiency. Once installed and maintained on the local system, it can give you a record of the source code.
Git is an easy to use, responsive version control system that works with text files and allows branching codes. Branching enables developers to try new ideas, go back to earlier branches, recall, merge and delete branches.
On the other hand, GitHub is an online, cloud-based database that helps developers keep track of Git projects outside the local server. GitHub is widely preferred for open-source projects and gives programmers control of task management tools.
An authorised person can access the Git repository and migrate data from GitHub from any part of the world. Since more and more companies are migrating their projects to Git, aspiring developers and Java professionals must build Git skills.
SQL is a crucial programming language to create databases, insert, analyse, and update data. Some of the standard database management systems using SQL are Oracle, Microsoft SQL Server, Ingres, etc.
With SQL, users can create functions in databases, place queries, and define data from data management systems. The five primary SQL commands are DDL, DML, DCL, TCL, and DQL.
- DDL: Data Definition Language (DDL) changes the table structures and permanently saves the changes in the databases, as these commands are auto-committed.
- DML: Data Manipulation Language (DML) is used to make changes in the database. The commands are not auto-committed, meaning you can retrieve changes.
- DCL: Data Control Language (DCL) grants or takes back authority from a user.
- TCL: Transaction Control Language uses commands likes INSERT, UPDATE, and DELETE and are auto-committed in the base.
- DQL: Data Query Language (DQL) is used to retrieve data from a database.
SQL is a query language used to update and retrieve data and communicate with a database. It is an important skill to master for creating Java-based applications.
