In June 1991, James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project. The original intention behind designing Java was for interactive television, however, it was too advanced for the digital cable television industry. Also, Java’s original name was Oak after an oak tree that was outside Gosling’s office. Then, the name changed to Green and at last for renamed Java, after the coffee that comes from Indonesia.

Java  was designed keeping five principles in mind-

  • Must be simple, object-oriented, and familiar.
  • Must be robust and secure.
  • Must be architecture-neutral and portable.
  • Must execute with high performance.
  • Must be interpreted, threaded, and dynamic.

What Is Java And Its Uses?

Java is one of the most popular programming languages used to create Web applications and platforms. It is an object-oriented language similar to C++, but with advanced and simplified features. Java is free to access and can run on all platforms. 

It possesses some important features like:

  • Simple
  • Portable
  • Object-oriented
  • Secured
  • Dynamic
  • Robust
  • High Performance
  • Multithreaded

“According to the Java official page, more than 1 billion computers and 3 billion mobile phones worldwide run Java.”                                                         


It is a concurrent language which means you can execute many statements at a time instead of sequentially executing it. It is a class-based and object-oriented programming language and is an independent programming language that follows the logic of “Write once, Run anywhere” i.e. the compiled code can run on all platforms which support java.

There are 3 main components of Java which are:

  1. JVM (Java Virtual Machine)
  2. JRE (Java Runtime Environment)
  3. JDK(Java Development Kit)

Although they all look similar, they are different and are meant for specific purposes.

JRE = JVM + libraries to run Java application

JDK = JRE + tools to develop Java application

 

Importance and Uses of Java

Due to its simplicity and robust nature, Java is being used in many industries as an essential core of their functionalities. It is used to create applications that run on a single computer or is distributed among servers and clients over a network. 

A small app module or applet can also be built by using Java. Java has become popular due to the following reasons-

  • You can write software on one platform and run it on any other platform (virtually).
  • You can create programs that run within a web browser and access available web services.
  • Development of server-side applications for online forums, stores, polls, HTML forms processing is possible due to Java.
  • Customizing apps and services by combining different apps and services is done using the Java language.
  • Writing powerful apps for mobile phones, remote processors, wireless modules, sensors, gateways, consumer products is done easily by using Java

Uses-

  1. 97% of all enterprise desktops run on Java.
  2. 89% of all desktops/computers in the U.S run on Java.
  3. There are 9 million Java developers worldwide and the number keeps going up!
  4. Java is the 1st choice for any developer.
  5. Java is the most widely used development platform in the world.
  6. 3 billion mobile phones in the world run on Java.
  7. All the Blu-ray disc players ship with Java.
  8. 125 million TV devices run on Java.
  9. 5 of the Top 5 Original Equipment Manufacturers Ship Java ME.
  10. It is also used in banking and retail for transaction management and billing applications respectively.

If you are a business owner or work in the IT sector, you must be aware of the importance of Java. Java is the most popular programming language in today’s time. Therefore, the need for Java job roles has gone up in the market. 

Thus, like our previous blogs, i.e, Skills To Look For In A Digital Marketer and How To Assess And Hire Data Scientists? We have made a concise list of job roles and skills related to the Java language.

Employee Engagement Trends to Watch for in 2020

In a landscape full of expensive work laptops, catered lunch, and other fancy benefits, engaging employees today is harder than ever. Despite these perks, however, the New York Daily reports that 70% of US employees are miserable at work. This is a large indicator of how leaders are still having trouble stimulating engagement with today’s employees, which is a workforce more diverse and younger than ever before. As new developments in technology and social norms occur at such a rapid pace, keeping up with the changing workforce and knowing how to engage employees can get a little difficult. That said, we’ve outlined a few ways you can stay ahead and have listed the incoming employee engagement trends of 2020. Be sustainable The millennial generation, who are in-line to be the next executives, want to work for companies who are sustainable — and the numbers don’t lie. A survey conducted by Swytch found that out of 1,000 employees, 70% are more likely to work for a company that has a strong green footprint, with 30% leaving a company due to not having a corporate sustainability agenda. Fortunately, it’s not that hard for companies to adapt — even using renewable energy is something that most companies can do, as it’s not as hard nor as expensive as it was before. In fact, thanks to decades of improved technology, Marcus notes that it's cheaper than ever to generate power from a solar grid. This is mainly because the cost to make it has lowered, making it possible for solar-powered projects to thrive, and companies to get into sustainability. While it isn’t meant to be a marketing scheme, being sustainable also provides an opportunity for outward marketing and branding as well. Offer remote or flexible work schedules Today’s generation highly values a work-life balance, and by offering remote or flexible work options, you’re fostering a culture that values these principles. This will increase employee retention as they see their employers value the same thing they do. Not to mention, quality of work and productivity will increase as granting them control over their time lets them choose the work times and environments that are best for them. If you want to start offering flexible work schedules, transitioning isn’t as hard as you think. Our article on ‘5 Ways to Effectively Improve Employee Engagement’ explains that you can start by offering telecommuting days, which lets employees work from home for 2 or 3 days a week. Download time-tracking tools and messaging apps such as Slack or Microsoft Teams to make collaborating and transitioning easier. Remember to also train managers to handle their new team of remote/flexible workers, as managing a flexible workforce isn’t the same as a traditional one. Provide opportunities for growth With the current technology, employees have an easier time developing their skillset — but they don’t want to do this without an opportunity to grow. Providing employees a clear path for growth along with some guidance will make them more motivated to reach higher and engage with the company. Without this, employees will become stagnant or feel demotivated as there are no goals to reach within the company. That said, make sure to pair your employees with mentors, or let them know about the next step in the corporate ladder and how to reach it. Provide seminars, give them challenging tasks, and let them have more opportunities to grow through conventions or events. An employee who feels like they’re valued by a company enough for the company to invest in their growth is an engaged one, and there’s no better way to do this than to give them opportunities
