The Positive and Negative Aspects of Java Programming

Object-oriented programming language

Objects in object-oriented programming are instances of a class which serve as a blueprint for creating those objects. A class defines an object’s properties and methods, and each object created from that class has its own set of properties and methods. This makes code easier to organise and manage, making it easier for developers to understand and maintain.

“Write once, run anywhere” philosophy allows for easy portability across different platforms”

“Write once, run anywhere” (WORA) is a tagline for the Java programming language’s cross-platform capabilities. That is, Java code can be written once and then run on any device or operating system that supports the JVM. The JVM interprets Java bytecode, which is the machine-readable format of Java programs on the host computer. This enables Java applications to be platform-independent as long as a JVM for the target platform.”

Large and active community with a wide variety of libraries and frameworks available

These libraries and frameworks offer a plethora of tools and resources to help developers create powerful and efficient Java applications. The Spring Framework, for example, is a popular framework for developing enterprise-level applications, whereas the Apache Hadoop framework is frequently used for big data processing.

Another benefit of the Java community is the wealth of online resources and tutorials available to assist developers in learning and to improve  their skills. The Java programming community has a large number of online forums, blogs, and websites, and many of these resources are open-source and freely available.

The Java community is also well-known for its emphasis on security and performance, making it a popular choice for many organisations and businesses. The community releases updates and security patches on a regular basis to address vulnerabilities and improve performance, and there are numerous tools and resources available for optimising and testing Java code.

Robust and secure, making it a popular choice for enterprise applications

Java developers should adhere to principles such as SOLID, DRY, and KISS, which promote the separation of concerns, avoiding code duplication, and using simple and maintainable code to ensure robustness. Additionally, Java developers should use testing frameworks such as JUnit to test the code and catch any bugs before deploying the application.

To ensure security, Java developers should adhere to security principles such as the OWASP Top 10 and the CERT Oracle Secure Coding Guidelines. Among these principles are secure input validation, secure data storage, and secure session management. To provide secure authentication and authorisation for the application, Java developers should also use security frameworks such as Spring Security or Apache Shiro.

Widely used in many industries, including finance, healthcare, and e-commerce

It’s a popular programming language for creating enterprise-level apps, mobile apps, and web-based apps. It’s also used to make games, financial applications, and scientific simulations. Many large companies and organisations use Java for software development, making it one of the world’s most widely used programming languages.

Complex to understand:

Java can be a difficult language to learn and master, especially for beginners. The language contains many features and libraries, which can make it difficult to understand and use effectively.

Verbosity:

Java is known for its verbosity, which can make writing and reading code difficult. This is particularly true when compared to other modern programming languages like Python or Ruby.

Performance:

In terms of performance, Java is not always the most efficient language. It may be slower than other languages, especially regarding startup time and memory usage.

Garbage Collection:

To manage memory, Java employs automatic garbage collection. While this can make coding easier, it can cause performance issues and unexpected behaviour
