The Java programming language is very popular and, truth be told, if it disappeared tomorrow, there would be millions of websites and apps that would no longer function. Java is recognized for its performance, security and dependability and those are just a few of the things that make Java a frequent developer choice.
The Java programming language has become so popular that, when people say the word ‘java’, most people no longer think of coffee! The Java language is object-oriented and it supports developers with a library of classes called Java API. It has a long and rich history, and is widely recognized for its performance, security and dependability. In this article, we review four important reasons for Java popularity among developers.
When considered within the brief but dynamic history of technology, Java is old-school. It has been around a long time and has worked to keep pace with the market and the needs of the users, as well as the evolving landscape of technology. Here we discuss four highlights of the Java universe and the benefits and uses of these tools.
For our example, we’ll use a module called ‘Employee’. For this example, we’ll need to display an employee’s personal details, in addition to other information, on the main employeeDetail page. We’ll separate the main page into several small jsp pages. The file that will display the employee’s personal information is empPersonalDetails.jsp and that page must be included in the main page (employeeDetails.jsp), using action.
Let’s assume that you have used apache tiles to provide consistent layout for each such sub-page (due to some requirement or just for decorative purpose) and you want to include that through a controller call. To accomplish that, you will use code similar to what we have detailed below:
The Jenkins tool is an open source Continuous Integration tool which is written in Java, and runs in a servlet container like Apache Tomcat. It can be used to build software written in various languages such as Java, .Net, PHP, C++ etc. This open-source, free software is available under MIT License.
If you have worked on a software development team, you will recognize these scenarios:
- You have a large team of engineers developing a software application. While committing the code in the repository, one of the developers forgets to commit one or two files. When other team members take the repository updates, they find problems in the code due to the missing file changes, and they have to spend a long time debugging the problems.
- Your engineering team is developing a software product. Your Business Analysis team needs frequent updates of the code to validate the changes or demonstrate new features to the customers. Preparing a new build and deploying it on the staging server for a BA team takes a significant amount of a developer’s valuable time.
