Why learning Java is critical for your technical career

by HSG on Nov 06, 2013 in java tutorial

One of the biggest challenges in pursuing a career in software development is to figure out which language you want to work. In addition to commonly used software programming languages like C, C++, Java a lot of new programming languages such as Python, Ruby on Rails have surfaced especially because they are used by a lot of consumer based start-ups these days.

With so many front and back end languages, the choice of learning Java is a failsafe decision and mastering Java can ensure that you have a bright future in software programming.

What is Java

Java is a computer programming language that is designed to be platform independent meaning that the language can virtually run on any hardware platform. This platform independence and an object oriented framework make Java the preferred language of development especially for client-server web applications.

Who Uses Java

Java is the defacto language for business applications and is pretty much used at every financial institution be it back end systems, trading portals, online banking etc. Java is also the preferred languages for developing e-commerce platforms and even most packaged enterprise applications like SAP have a huge codebase written in Java.

The popularity of Java is best understood by looking at some companies that use Java. Companies like Facebook, Linkedin, Google, E-bay extensively use Java in addition to C++, Python etc. Some of the largest enterprise software vendors like Oracle and SAP use Java. Infact, the purchase of Sun Microsystems (Java was licensed under an open source model by Sun) by Oracle clearly suggests the importance of Java in the technology space.

Why You Need To Learn Java

While reading the latest news on languages might suggest that newer languages like Python are the future of programming languages, Java continues to remain one language every technology company has to use at some stage.

One of the most important yet overlooked aspects about Java is the presence of a huge ecosystem around the language framework. Pretty much anything you want to do; there is a library available for you via Javadocs or reusable APIs.

Performance and scalability are critical parameters for evaluating a programming language. This is where Java excels due to its reusability and encapsulation features which reduce code duplications to a large extent. This is the very reason that despite being developed using Ruby on Rails, Twitter is increasing looking to shift it’s codebase to Java to improve performance

Java has existed for more than a decade and has remained quite stable in the number of updated releases it has had over the years. This makes it easier to undergo Java training and become an expert at it unlike other languages where the language itself keeps changing frequently thereby increasing the costs of training.

little beats a good book for depth and insight. the price we pay is time spent reading but it's time worth spending.

did you know? HSG is one of the foremost training companies in the United States

Information Technology Training that enables companies to build better applications and expertly manage the software development process.

Our courses focus on two areas: the most current and critical object-oriented and component based tools, technologies and languages; and the fundamentals of effective development methodology. Our programs are designed to deliver technology essentials while improving development staff productivity.

Personalized courses for unique business and technology needs

An experienced trainer and faculty member will identify the client's individual training requirements, then adapt and tailor the course appropriately. Our custom training solutions reduce time, risk and cost while keeping development teams motivated. The Hartmann Software Group's faculty consists of veteran software engineers, some of whom currently teach at several Colorado Universities. Our faculty's wealth of knowledge combined with their continued real world consulting experience enables us to produce more effective training programs to ensure our clients receive the highest quality and most relevant instruction available. Instruction is available at client locations or at various training facilities located in the metropolitan Denver area.

Upcoming Classes

consulting services we do what we know ... write software

Design and Development
Application lifecycle management
We generate use cases, UML documentation, architect the system, create an object model, iteratively develop the system, unit and system test and modularize where necessary. These types of engagements are typically longterm and, almost always, incorporate a variety of software technologies.
If you are in need of expertise but only require the assistance of one or two engineers, the Hartmann Software Group can be of help. Instead of procuring talent by way of a placement agency who is likely to contact us, come to the Hartmann Software Group directly. You may realize some savings.
Mentor
The best way to learn is by doing.

The coaching program integrates our course instruction with hands on software development practices. By employing XP (Extreme Programming) techniques, we teach students as follows:

Configure and integrate the needed development tools

MOntitor each students progress and offer feedback, perspective and alternatives when needed.

Establish an Action plan to yield a set of deliverables in order to guarantee productive learning.

Establish an Commit to a deliverable time line.

Hold each student accountable to a standard that is comparable to that of an engineer/project manager with at least one year's experience in the field.

These coaching cycles typically last 2-4 weeks in duration.

Provide Expertise
Services for your business growth.
With the introduction of smart devices, e-marketplaces, electronic forms, SEO practices, big data, virtual office environments, media streaming and so much more, there is hardly a business whose livelihood is not, in some way, dependent upon the inclusion of such software functionality into its online presence, work environment and product offerings. Such inclusion often presents a complex array of challenges that are far beyond the expertise of the business as it demands an understanding of technological options, modular decomposition, backend systems integration and web services. Most importantly, the business requires IT talent and expertise; this is where the Hartmann Software Group shines. To that end, here is an overview of some of the services that we offer:
