Ask any developer and they'd tell you that your choice of programming language can make or break your development project. So while options are abundant out there to choose from, development teams find themselves stuck between two highly popular programming languages - Java and C++. Also, while both of them are object-oriented programming languages, there are nonetheless many factors that differentiate the two.

For starters, C++, an expansion of the C language, and Java have distinctive aims when it comes to design. Also, while C++ was brought in for system and app development, Java was initially aimed to serve as an interpreter for printing systems that eventually supported network computing. You get where we are going this. So, let's delve into details of the critical differences between them to see if one of them is decidedly better than the other.

  1. Thread support: Java offers built-in support for threads; it gets a thread class that can be then inherited to build a new thread overriding the run method. On the other hand, C++ lacks any inherent support for threads and developers have to make use of third-party libraries in this context.

  2. Documentation comment: When it comes to documentation comments, C++ does not offer any support for it. Thought, Java provides built-in support for documentation. What this means is that Java source files are capable of containing their documentation. It, in turn, is read by a different tool, which is typically Java doc, and then reformatted into HTML. How does it help developers, you ask? Well, this Java functionality allows them to ensure that all the documentation is maintained easily.
  3. Runtime error detection: Another crucial point of discussion, when it comes to choosing between C++ and Java, is the responsibility for runtime error detection. Who is responsible for it? Well, in C++ it is the developer's job. However, in Java, the system is responsible for detecting runtime errors.
  4. Libraries: Any developer worth his salt understands and appreciates libraries as well as the role they play in programming. So in this context, C++ comes with a relatively lower level of functionalities. Whereas Java tends to a broad range of possibilities with its provision of a wide variety of classes for several high-level and crucial services.
  5. Portability: Yet another vital factor in the decision between the two programming languages is their portability. C++ is a platform-dependent language since the source code is required to be recompiled for every different platform. Contrastingly, Java makes use of the concept of bytecode, which, by the way, is independent of the platform. So, when it comes to development projects and their compatibility with different platforms? It suggests that Java code can be utilized with the platform-specific JVM.

The discussion makes it abundantly clear which one between Java and C++ is a better choice. So, when you make the right choice for your project, the next step should be to find a trusted vendor who offers Java-based development services to ensure you can harness all the benefits provided by Java.
