So, Java is the best career choice to shine as a Java Developer skills in 2024.

Java Developer Skills

A Java developer is a software professional who develops software applications using Java programming. They will be active throughout the development life cycle of a product. These developers are capable of analyzing and identifying technical problems for applications,products,websites and more. They provide efficient solutions using Java language and should come up with efficient, workable solutions.

The Top Skills of Java Developers are:

  • Core Skills
  • Java ecosystem
  • MVC Design Pattern
  • JDBC and SQL
  • Java Frameworks & Libraries
  • Java GUI Frameworks
  • Java Concurrency
  • Java Server Pages and Servlets
  • Exception handling
  • Java Building Tools
  • Advanced Java
  • ElasticSearch
  • Microservices
  • Cloud services
  • Docker

1.Core Skills

As a Java developer, it is very important to have a strong understanding of core Java programming language concepts.Develop these Java concepts using practical training to have a solid knowledge

Java data types,variables
  • Conditional statements
  • Looping
  • Exception handling
  • Interfaces
  • Lambda features
  • Collection Framework

Knowledge of object-oriented principles – inheritance, polymorphism, encapsulation and abstraction is very essential.To code effectively for robust application, master these concepts.Always update your knowledge with the latest trends and best practices.

2.Java ecosystem

To create various java applications,Java provides a software platform with a collection of resources. The Java Ecosystem composed of the following:

  • Java Virtual Machine (JVM) – It provides a run-time environment to load, verify, and execute Java Bytecode with program memory.
  • Java Runtime Environment (JRE) – It is the communicative link between Java programs and the operating system. It provides libraries and other resources/tools.
  • Java Developer Kit (JDK) – It is a combination of JVM and JRE along with tools and libraries.

3.MVC Design Pattern

Model – View – Controller Design Pattern is a design pattern used in Java applications development. It specifies the application – data as model, presentation as information, and control as information. MVC relates to the interaction layer of an application. The Model contains the application data without any logic.The View presents the model’s data to the user and how to access the model’s data.The Controller is between the view and the model which listens to events triggered by the view and executes the reaction to these events. The reaction is often calling a method on the model.

4.JDBC and SQL

Structured Query Language(SQL) and Java Database Connectivity(JDBC) skills are important for Java developers to handle data effectively. These skills help to store, organize, and manipulate data using databases. It allows you to interact with databases, execute queries, and retrieve data.Java developers can access database data or troubleshoot database issues to improve application performance and reliability.
Java Developers can work as backend developers, so learning JDBC,SQL is a core skill. SQL is the most common tool to interact and analyze data.To learn SQL,Join SQL training courses.

5.Java Frameworks & Libraries

To build complex applications, Java frameworks and libraries are essential for Java developers.It helps to work on web applications, mobile apps, desktop software. Developers use them during the development process and improve the code quality. The common frameworks to build robust applications are:

  • Spring: It is the must have skill for a Java programmer. This framework helps to write testable code easier.It is useful in building web applications and services. With powerful tools,Spring provides dependency injection and model-view-controller architecture.
  • Spring Boot: To create microservices, RESTful APIs, applications,Spring Boot is a must learn skill. It provides auto-configuration which reduces the development time.To learn Spring Boot,Join Spring Boot courses now.
  • Struts: To create web applications, user interfaces, web services, struts is used using JSP,servlet.

6.Java GUI Frameworks

  • GUI – Graphic User Interfac: It includes user-friendly components like buttons, textfield, etc. to make the user interact with the software.The best Java GUI frameworks are AWT, Swing, JavaFX, Apache Pivot, etc.
  • Abstract Window Toolkit (AWT):It is used for a smaller Java UI application and supports GUI programming. It provides user interface components,graphics tools.
  • Swing:It is the primer framework for building new GUI-based Java applications. It has a lot of rich UI components.

7.Java Concurrency

Multithreading and multitasking programming are used in java programming. Learning these concurrency techniques are important to code effectively.

  • Multithreading – is a java feature to run multiple threads concurrently.Thread is a small unit of task in the program.
  • Multi-tasking – To achieve better performance,several tasks are executed simultaneously.

8.Java Server Pages and Servlets

JSP is a programming technology for developing web pages. It supports inserting java codes in HTML codes using special JSP tags. It is used to fulfill user interface.Servlet is a Java programming class to create web pages dynamically. Using HTML forms,user data is collected by servlet and also using query records from databases. These two web development techniques play an important role on the server side. So it is essential to learn as a java developer.

9. Exception handling

Exception handling is the important java mechanism to handle run-time errors which interrupts the program flow. Exception is an unexpected or unwanted event that happens during program execution like:

  • ClassNotFoundException
  • IOException
  • SQLException
  • RemoteException

Exception handler is a block of code to handle run-time errors. Try, catch, throw, throws, and finally are keywords used in java exception handling.

10. Java Building Tools

To develop highly scalable software, Advanced Java concepts are necessary for Java developers. The Advanced Java concepts are

  • Concurrency
