It as well also gives technical support and improvisation in the experience of the developers. This is certainly one of the essential tools that a JAVA programmer needs to have an understanding of. The prime features of the Undertow loader are as given below:
- Deploy Undertow, Jetty, or Tomcat directly
- To bring a reduction in building configuration providing dependencies
- Creation of independent applications in spring
- Automatically configuring spring attachments
- Providing complete security and technological support
- No code generation is required for XML configuration
Angular JS- This is a specific JavaScript library for the purpose of UI development and is termed as ReactJS and Angular is the framework. These two prime technologies need to be familiar to the JAVA developer. Angular 2 refers to the framework for web applications that can use in open source. The prime features are Directives, templates, advanced dependency, and a child router.
Apache Spark and Kafka- Apache Spark and Kafka are two must-have technologies for Java 2021 developers. This is a framework for the purpose of cluster computing that is made available in open source.

In specific, the code of Apache Kafka in Java and Scala. Kafka can make use of basic APIs that include Producer API, Connector API, Stream API, and lastly Consumer API. There are some well-known or defined features of Apache Spark that include real-time stream processing, advanced analysis, speed, high performance, reliability, robustness, data conversion, docker, no downtime, multilingual support, and more.
Docker- This is a language that is written in the Go language and developed on Linux. Docker is a significant tool for learning Java 2021 developers. Docker provides tools that are of much help for the purpose of containerization. It as well also had a stable release at the end of the year 2018. The container or set of software packages is managed by Docker.
Unit Testing- Unit testing refers to an essential skills for the Java developers that one should learn in the upcoming years. For all those working in Java, towards integration as well as unit testing. Mockito is also a tool which will help one to make use of unit testing skills.
DevOps- DevOps refers to one of the most significant things that Java developers are required to learn in the year 2021. This is an effective way of operating software development. It can also be referred to as an effective method for various operations of software development. This shortens the development cycle of a system providing required updates and features to the enterprise objects. This is something that develops a closer relationship between processes and IT development, allowing for better level of collaboration as well as communication. Prime features of DevOps implementation include tasks being done in small steps, support for the existing systems, making use of system translation and deployment of DevOps toolkit.
Groovy- This as well is a very essential tool for the Java developers of the year 2021. Apache Groovy praises Java as it is something that supports Java syntax. This can make use of a Java platform and can make use of a scripting or programming language. This influences by Java, Ruby, Perl and Python.

However, it does not mean that Java developers have to learn all of the above-mentioned skills. But certainly, all of the above-mentioned skills are something that is looked at by top Java application development companies irrespective of the countries they operate in. Java developers need to have a proper knowledge to ensure that what they develop is good and helpful for the society. Without having a updated knowledge it cannot be expected that the software being developed will be good for the society
