Toolkit-based design: Toolkit based design helps to restraint the element composed. Cryptographic verification of history: Git stores history of every version and the version is stored by a unique id. Strong Support for non-linear expansion: Merging and Branching are the two main factors that are provided by Git. Git provides strong support for Non-linear development. Well-organized management of large projects: Locally stored repository helps to manage large projects in a well-organized manner.
Git also supports these publishing tools. Selenium Selenium Web Driver with Java is one of the technologies a Java developer should know in Here are the three main reasons you should opt Jenkins: It provides better Software Quality than others. It also provides more time for developers to work on the projects as automated systems manage most of the work.
As integration is managed by automated systems, so development is much faster in Jenkins. Followings are the characteristics of RESTful Services: Client-server based architecture provides operations like management, delivery and server hosting. It also helps users to use services and resources.
It is basically a shared computing model that shares resources. Cacheable architecture is the main reason for blocking web APIs and Applications. A stack technology is not involved in this blockage. It is important to store cache for scalability. It means a request can be passed to another server if a server is busy. The multi-layered system provides a keen response to the clients. REST is an approach where one can describe any web services. It provides flexibility, scalability, and liberty to opt for any technology and platform.
Spring Security Spring Security is a framework that provides access control and authentication. To shorten build configuration, deliver dependencies.
Create stand-alone Spring applications. The key design principles which are important for Java developers are:. After Design, Architectural patterns are a good starting point for the developers. Java developers need to catch up with the trend of building microservices instead of monolithic applications.
Developers need to have an understanding of Docker Container. Docker is used for creating and compiling microservices applications in different environments. Microservices Architecture areas are important areas for a developer to learn. The key areas are :. Microservices best practices are important for the developer to know. They are:. Java developers need to have DevOps skills for continuous integration and continuous deployment.
Developers need to know programming best practices, creating an infrastructure environment, building scripts and guidelines. The key DevOps tools which developers need to know are shown in the table below. The DevOps key principles which a developer must know are :.
You can start evaluating the following DevOps Automation tools:. Java developers need to have knowledge of unit testing frameworks such as JUnit and Mockito. Developers need to develop and create unit tests for the code. JUnit is used for Java code unit testing. Xunit is the parent framework of JUnit. Unit testing coverage in a project is ensured by executing the unit test suites.
Unit Testing is performed manually and using automated methods. JUnit helps in improving the quality and efficiency of the developer. This open-source software framework has features related to the below:. A unit test has a test case that checks the functionality of a program or a method in the class.
Given the input and the result, a test case is written for checking the input and the results. The precondition checks for the input are done. Postcondition checks for the result are done. For every test case, you can have a single positive and negative test.
Mockito is a unit test framework based on mocking. Mocking is based on isolating the program and testing it. Linus Torvalds founded Git in , and you can use the Git project directly as it is a complete version control system. We have listed some of Git's features to help you learn more about Git.
Distributed extension: The repository helps Git to create a copy of the development history. Linking approaches: Git has a toolkit-based design that provides a well-defined model. Toolkit-based design: Toolkit-based design helps reduce the composite part. Strong support for non-linear extension: Scaling and branching are two essential factors that Git offers. Git provides strong support for non-linear development.
Well-organized management of large projects: A locally stored repository helps manage large projects transparently. Git also supports these publishing tools.
The Selenium web driver in Java is one of the technologies a Java developer should know in Selenium provides tools for testing web applications using test frameworks. It includes automation features for web applications. Here are the critical elements of Selenium:. Jenkins is a technology derived from JAVA programming, as the open-source automation Continuous Delivery and Integration automate the software development process which supports various version control tools.
Jenkins has made its plugins available for integration with code written in another language. Here are three main reasons why you should choose Jenkins. It offers better quality software than others. Because automated systems manage integration, development at Jenkins is much faster. It is a suggestion that presents architectural style and is a must for Java developers. It improves web service performance. It also defines scalability and performance constraints.
It is one of the most desirable things in for Java developers. The recreational API use for communication in web service development. Below are the features of RESTful services:. The client-server-based architecture provides features such as administration, deployment, and hosting of servers. It also assists users in using services and resources.
It is essentially a shared computing model in which resources share. A cacheable architecture is the main reason for blocking web APIs and applications.
Stack technology is not involved in this blocking. It is essential to cache for scalability. A multi-tiered system ensures fast response times for clients. A unified interface provides a single resource identifier URI for storing records. REST is an approach to describing any web service.
