Distributed Networking

Internet is all about distributed networking and Java is indigenously designed for distributed computing with seamless networking capability. Writing network programs in Java is a cake walk for programmers.

Secure & Robust

On the internet security is one of the main concerns; Java is designed to provide a secure development and deployment environment. The Java platform allows users to download code over a network which is not trusted and run in a secure environment where it can do no harm. It also makes security levels and restrictions highly configurable.

Programmer Efficiency

The ability of Java to get results is one of the main reasons it is most preferred by programmers. Java has a set of well designed API’s which allows programmers to code efficiently with fewer bugs and considerable reduction in development time.

Highly Scalable

Big Data Technology

Big Data which is transforming the organization into being data driven is also using Java. Hadoop as well other big data technologies are using Java for example Apache’s Java-based HBase and Accumulo(open source) and ElasticSearch .

Server Apps

Java is used in writing server side applications where there is no front end. The main purpose of these server side applications is to receive data from one server process it and send it to other processes. This functionality of Java is extensively used by global investment banks like Goldman Sachs, Barclay, and Standard Charted etc for building financial applications for server side.

Scientific Applications

Java is being used in many scientific applications because of its advantages like security, portability and robustness. It is being used in natural language processing and other important applications. The multi threading feature of Java provides high level of concurrency.

Here are some more reasons that make java a  popular choice for programmers.
