How to become a java developer?

Java is one of the most used programming languages worldwide. Approximately 9 million developers around the world use it. Java is used to create customized programs, is very adaptable and can operate practically on every platform in a safe manner. It is fast, secure and reliable and therefore used to make applications ranging from software design, gaming technology to web and mobile applications. Java is extremely versatile and coder friendly. Since most large software companies have their software systems and backend services implemented in Java, Java developers are some of the most sought professionals in the world today. 

Who is a Java developer?

Java developers take care of planning, creating and overseeing Java-based software and processes. For instance, software tools, scientific and online applications, and also android applications. Simple actions that we do everyday like searching for something on Wikipedia or playing a game will always involve a Java developer. Java developers operate in two fields: mobile app development and software backend development. Although other programming languages like Python and Go have become very popular, Java still remains strong and effective. 

To become a successful Java developer, there are several steps to keep in mind. They are listed below.
1. Master the Core Java SE
You will have to begin by mastering the Core Java (Java SE) as much as you can. You should be familiar with basic ideas such as loops, arrays, operators. Also, you should at least have a basic understanding of general purpose APIs that are available in Java SE. 
2. Keep practicing Java
To become a successful Java developer, you need to apply the components learned in Core Java and become an expert. When you learn the language constraints and recommended design principles, you will find it easy to offer a theoretical fix to a problem. However, there are often challenges in putting ideas to practice. You will need to code and practice Java as often as you can and attempt to create small projects on different subjects.
3. Learn Java EE
When you complete learning Core Java, start learning Advanced Java which is also known as Java EE (Enterprise Edition). When you learn that, you can concentrate on web development. For web specifications, this includes tools like Java Server Faces, Servlet, WebSocket and many more. 
4. Make projects with Servlets and JSP
All Java knowledge that you gain must be combined with front-end technologies like HTML, CSS and JavaScript. You could attempt to develop small projects on specific subjects so that it helps you develop your thinking skills. Without working on projects, it will be difficult for you to determine your programming level. 
5. Learn Hibernate and Spring Frameworks
To become an expert in Java coding, you will have to learn Java frameworks such as the Spring Framework and Hibernate Framework. These Java frameworks are used most widely. The possibility of you being selected as a Java developer in an organization is high if you are familiar with these frameworks and can create projects with them. 

Becoming a Java Developer

Most businesses that wish to stay ahead of the game in the age of digital transformation, will pay close attention to hiring devoted Java developers. Normally Java Developers are classified into three levels: Junior Java Developer (Up to 2 years’ experience), Senior Java Developer (more than 5 years’ experience) and Lead Java Developer (More than 10 years’ experience). It is not just about experience but also the skill of the developer. 

To be a good Java developer, you need to have the following skills:

  • Research and organization
  • Using Java EE platform for application design and development
  • Create project essential modules and functionalities for applications
  • Participate in the entire development process
  • Code effectively with a well-tested design
  • Design and create software component releases
  • Positivity, analytical thinking, and problem-solving abilities
  • Determining risk and carrying out action plans for risk mitigation
