Why learn Java?
A programming world without Java is inconceivable. Widely used in the distributed environment of the internet, it is one of the most popular programming languages for Android smartphones and favoured for development of devices and software applications. The functioning of a large number of websites and applications depends on the installation of Java which is fast, secure and reliable. From data centres and laptops to gaming consoles, scientific supercomputers and the Internet, Java is widely used and implemented. Created in 1995, and owned by Oracle, the programming language offers a lot of advantages to the organizations and individuals working on it.
Programs created on Java offer portability and can run in any network. Easy to learn and simple to use, the programming language can be used on different platforms like Windows, Mac, Linux, Raspberry Pi etc. The language is designed in a way that once written it does not require recompilation which saves time and money. Java applications are compiled to “bytecode” that are capable of running on any virtual machine irrespective of the computer architecture.
Benefits:
Java is a general-purpose computer programming language that is object-oriented, concurrent and class-based and designed to have minimal dependencies when it comes to its implementation.
Individual Benefits: A Java Certification helps individuals:
- Train for jobs in the software testing domain that rely extensively upon Java programming for their applications
- Move up in their career in Software development and coding fields
- Prepare to be part of the Java programming trend
- As per Payscale.com, a Java Developer in the US earns $73,336 on an average.
Organizational Benefits: Training their workforce on Java gives organizations several benefits:
- The code is robust and guarantees integrity
- Java does not use pointers and therefore data is secure
- Java applet has the characteristic of offering flexibility
- Java is object-oriented
- It's free to use and is utilized by over 116,818 websites currently, which makes up for 1.72% of all websites
With Java being the core language with which a majority of applications are now built, Java developers are in great demand in the software industry all over the world. Certification in Java programming will definitely help software professionals distinguish themselves from non-certified individuals and move ahead in their career. Java continues to be among the top programming languages used by programmers for the development of web, desktop and mobile applications.
Java training courses are in great demand in the developer and programming community given the ease of learning for developers with a huge community to support.
