Java is the most popular and evergreen programming language in the world of the IT Industry because of its support, usability, security and user-friendly. And Java Developers are in a nonstop race on upgrading their skills for its demand. Java is a high-level language and software-only platform. It runs on more than 50 million personal computers and billions of devices worldwide & 9 million developers have created Java applications in all major industries. Java was first developed in 1995 by Sun Microsystems in the US, which is a concurrent, class-based, and object-oriented programming language based on the syntax of C and C++. Java is fast, secure, and extremely versatile. Therefore, it develops applications like software design, gaming technology, and web & mobile applications. Java is an ideal choice for cross-platform apps like the web, Android, cloud, machine learning environments, and the IoT (Internet of Things).

Despite its age and legacy, Java is one of the most known programming languages today. According to a 2021 Statista report, 65% of software developers use Java as a programming language around the globe. No surprise that Java developers have greater demand! If you are eager about the technology and interested in building a career as Java Developer, look no further. 

According to the 2020 HackerRank Developer Skills Report, Java is the 2nd most widely known programming language globally after C. One of the most important advantages of this language is indeed a vast community that is ready to share knowledge and support each other. The two primary elements of the Java platform are the Java Application Programming Interface (API), which is a library of Java command lines, and the Java Virtual Machine (JVM), which decrypts Java code into machine language. Let’s know about the technical skills of Full Stack Java developers below. 

Java Developer Skills (Technical)


Core Java​​​​​​​

• Object-Oriented Programming Skills:

This approach introduces class and object style of coding that deals with the concepts of Inheritance, Encapsulation, Abstraction, and Polymorphism. The motto of OOP is to bind the data and the functions together, to improve code stability and safety.

• Design Patterns in Java:

These are standard solutions followed to solve routine problems faced in the software designing life cycle. Every Design Pattern works as a blueprint that permits customization to decode any given design problem in any code during the development of software modules. 

• Abstract Classes in Java:

These help the developers to achieve abstraction. Abstraction in object-oriented programming lessens code intricacy by showing only the pertinent details of the objects used in the program and improves code readability. 

• Interface in Java:

Java Interface is an advanced level of achieving abstraction in the Java Programming Language. The interface in Java enables a better and more efficient way of achieving abstraction in Java

• Serialization in Java:

This is a concept that deals with the conversion of objects into a byte stream to transport the Java objects from one Java Virtual Machine to the other and recreate them to the original form. Serialization enables developers to meet various factors in real-time programming. Almost everything you can do using Java so, let us know its features/benefits below.

USPs/Benefits: ​​​​​​​

• Simple:

Java is a simple programming language and is effortless to understand because it does not include intricacies that are present in programming languages before.  

• Object-Oriented:

In Java everything is written in terms of classes and objects. The object is a real-world entity that can symbolize any person, place, or thing and can differentiate from others. 

• Platform Independent:

The design goal of Javasoft people is to create a language that must work on any platform. Java permits programmers to write their program on any machine with any configuration and to run it on any other machine with different configurations. 

• Portable:

The WORA (Write Once Run Anywhere) concept and platform-independent feature make Java portable. So, by using Java, the developers can deliver the same result on any machine, by writing code only once. The reason behind this is JVM (Java Virtual Machine) and bytecode. 

• Robust:

Java is capable of handling unexpected termination of a program. There are two reasons behind this, as it has a most influential and valuable feature called Exception Handling. If an exception occurs in Java code then no harm will happen, but in other low-level languages, the program will crash. Another reason is the memory management features. Unlike other low-level languages, Java provides a runtime Garbage collector presented by JVM, which gathers all the unused variables. The garbage collector is a special program under JVM that runs from time to time and notices many unused variables and objects and drags them from the memory to free up space. 

• Secure:

In today’s era, security is a major concern of every application. Java supplies security features to the programmers for the problems like virus threats, tampering, eavesdropping, and impersonation can be handled or minimized using Java. 

• Interpreted:

The Java programming language uses both a compiler and an interpreter. Java programs are accumulated to develop bytecode files then JVM interprets the bytecode file during execution. 

• Multi-Threaded:

Thread is a lightweight and independent subprocess of a running program (i.e., process) that shares resources. And when multiple threads conduct simultaneously is called multithreading. 

Java is a trusted and customizable programming language that has transformed the entire field of software development. Powered by comprehensive libraries and tools, Java helps developers swiftly create high-quality, dependable programs. So, let’s take a look at what does the future of Java hold. 


CSM Tech with 120+ in-house Java experts who have more than 8-10 years of experience, has the best solution to offer for its clients and others who are in search of such a solution.

Future scope of Java: 

Java will undoubtedly continue to be a widely used language in the future. The strong demand for proficiency in Java stems from the large installed base of Java applications. Additionally, Java is frequently updated with new features and capabilities, enabling it to stay relevant in a constantly evolving market. However, it’s feasible that Java may only modestly cede its dominance to emerging languages in the future, particularly in web development. CSM developer community of Java is so vast and is the strength of the Java language. This technology is growing at a fast pace and job opportunities are also increasing for Java developers having good knowledge of Java technologies. As Java is scalable, you can find Java in mobile applications, software applications, servers, and web applications. The application built in Java can be distributed over the internet or on any network. Use more! Learn more!
