Who is a Java Software Engineer?

A Java software engineer is an individual that is solely responsible for developing and designing software applications by utilizing the java programming language. He or she works closely with web developers and other software engineers to achieve his or her objective. Java software engineers are active participants in every stage of the development cycle that is from the initial design to the final testing. The software product development cycle may include: analyzing system and user requirements, writing clean java code, designing flow charts, running tests to enhance system functionality, and troubleshooting bugs. To ensure that you are a successful java software engineer, you need to possess extensive knowledge of java coding development, the ability to manage projects, and excellent software troubleshooting skills. A top-notch java software engineer can also work closely with the development team to formulate high-quality software applications that the needs of the user.


What is Java?

Before we proceed, there is a serious need to understand what the concept is called “java”.

Java is a programming language developers utilize for mobile phones, web development, and software. The history of java can be traced to the 1990s when a small team known as “the Green Team” first brought about the concept of java. There was a man called James Gosling who was part of the team and in later years became known as the “Father of Java” because of his notable contribution to the concept. Gosling developed Java while working as an engineer at Sun Microsystems ( a subsidiary of Oracle today). Java was initially designed to be the following:

  • Portable
  • Simple
  • Robust
  • Platform –independent
  • High Performance
  • Architecture Neutral
  • Interpreted
  • Dynamic
  • Secures
  • Multithreaded

Java was first commissioned in the year 1995 and many modern programming languages have descended from it, examples of such programming languages are Scala, JavaScript, PHP, and Python. Java continues to remain relevant because it is one of the easiest and most popular programming languages to learn from. In this modern dispensation, there are four editions of java:

  • Java Card: This is utilized to develop programs for devices with small processing abilities or capacities such as SIM cards and ATM cards
  • Java Standard Editions (Java SE): This is utilized to develop programs for desktops and servers
  • Java Micro Edition (Java ME): This is utilized to develop programs for  mobile devices with high capacities such as iOS and Android phones
  • Java Platform Enterprise Edition (Java EE): this is used to develop large-scale applications.

Java versus Java Script

Java and JavaScript have similar names and people use them interchangeably, however, they differ in the way they function. The difference is that java is a compiling language, which implies that it is translated into a machine code by compilers whereas JavaScript is an interpreted scripting language, which implies, it is translated into machine codes when it runs.

Java and JavaScript have different use; Software engineers use java for server-side development and JavaScript for client-side projects.


Differences Between a Java Developer and a Java Software Engineer?

Contemporary developers confuse java developers with software engineers but the fact remains that these professionals are different. The difference is that Java Developers are highly specialized professionals that work particularly with java projects and only java projects whereas software engineers have a wide range of knowledge to work on different programming languages and projects. Although Java developers and software engineers have similar roles they play and also possess similar skills: most professionals swap into the two roles for a new challenge or to acquire a new skill.
