Few technologies can boast of remaining relevant for nearly three decades. Java is one of the names on this short list. Although there are many new programming languages ​​available in today's world of software and website development, Java is still among the most used and preferred options for development work.

Experts simply cannot deny the fact that Java is one of the most effective and powerful languages ​​ever created. It is also one of the most used programming languages ​​in many areas. However, this doesn't mean that Java doesn't have its own unique sets of disadvantages in addition to its many advantages.

It is important to understand the pros and cons associated with any programming language before starting a project in it. Whether choosing to develop programs in-house or outsource Java development, every company or organization should know what they are getting with a Java-based program.

What is Java?

Java is an all-terrain object-oriented programming language used to develop software applications. It is one of the main languages ​​in the world thanks to the fact that it is open source and runs on all operating systems. Java is known for its “Write Once, Run Anywhere” features.

Sun Microsystems developed Java in 1995 as a programming language similar to C and C++ with adaptations for ease of use and advanced features. In today's market, developers use Java to create scalable, portable, robust, and distributed software products. These products range from server networks to video games, applications and websites.

The Pros of Java Development

Let's look at the positive side first.

  1. Java is simple: A programming language is “simple” if it is easy to learn and understand. Not only is Java that, but its code is also easy to debug and maintain over time. It is also less complex than other similar languages ​​such as C and C++. These languages ​​have many complex features such as storage classes, operator overloading, and explicit pointer concepts, which are sometimes complicated and not in Java.
  2. It has object-oriented programming: Java encompasses object-oriented programming, which is a coding concept that defines not only the data type and its structure but also its set of applied functions. This programming method makes the data structure a manipulable object to allow the creation of relationships between other objects. Object-oriented programming is an advantage because it allows developers to easily reuse objects in other programs, prevents errors by allowing objects to hide more sensitive information, and helps with project pre-planning and organization. This also means that maintaining Java code is simple and modernizing legacy code is easy.
  3. Java is a high-level language with only a slight learning curve: Whether a developer is just starting out or has years of experience, learning Java is easy. As a high-level language, Java is very similar to human language. This means that where other languages ​​look like machine code, Java and other high-level options require conversion using compilers and interpreters. This makes development generally much simpler.
  4. It is a safe programming language: In fact, Java reduces security threats and risks by avoiding the use of explicit pointers. Sometimes pointers cause unauthorized memory access as they store the memory address of other values. Since the concept of pointers does not exist in Java, this is not a problem. The language also offers a security manager for each application that allows developers to define access rules for each class.
  5. Java is a distributed language: Java provides a mechanism for sharing data and programs among multiple computers to help improve system efficiency and performance. This allows for distributed computing, or multiple computers on a network working together. This is a great help in developing network applications that can contribute to both application and data functionality.
  6. Java offers several APIs for application development: Java APIs (or Application Programming Interfaces) are sets of commands or communication methods between various activities. This includes things like database connection, networking, utilities, and more.
  7. Supports multithreading: This means that it offers the ability for a program to run multiple tasks or threads simultaneously within a program.

The cons of Java development

The other side of the coin.

  1. Requires a very significant space for memory: When compared to native languages, Java consumes a lot of memory and is slower. Being a high-level language, each line of code requires interpretation into machine-level code. This can decrease performance due to the extra level of abstraction and compilation. Java's garbage collector is a useful feature, but it also sometimes causes performance issues due to excessive memory usage and garbage collection.
  2. Java code is verbose: Because it is a high-level language very similar to the way humans speak, Java code contains many words. This sometimes results in long, complex sentences. Although the language focuses on being more manageable than others, it compromises this with long explanations and sometimes overly complex code due to its wordiness.
  3. Lacks a native look and feel when used for desktop: Developers must use different language-specific tools to create the graphical user interface (GUI) of a Java program. While mobile apps are typically not a big problem, Java is somewhat weak when it comes to desktop user interfaces and user experience. There are a few GUI builders available for Java programmers to choose from. However, choosing the right GUI fit for a specific project requires additional research.

Conclusion

Most organizations continue to use Java in some form in their programming as it is quite an advantageous programming language. Although it has some flaws or disadvantages, its advantages far outweigh these problems. There's a reason why it continues to be ranked as one of the top programming languages ​​year after year by the development community.
