Which Programming Language Is Better: C++ or Java?

When comparing programming languages, it is often difficult to determine which is more powerful. In terms of C++ and Java, both languages have unique strengths and weaknesses. In order to make an informed decision about which language to focus on learning in 2022, it is important to consider the current and upcoming trends in the software development industry. C++ is a powerful language that is still used in many applications today, while Java is the language of choice for many modern web applications. Ultimately, it is up to the individual to decide which language will best meet their needs and goals.

When deciding which programming language to use for a project, there are several factors to consider. Type, complexity, time to market (TTM), scalability, security, and other criteria must all be taken into account. While programming languages that are more sophisticated may result in applications that are more flexible, extensible, and packed with features, they tend to require more time to develop the code for them. Therefore, it is important to weigh these factors carefully when selecting the best language for a project.

Software developers can benefit from understanding the technical differences between C++ and Java when making decisions about which programming language to use for their projects. It is important to consider the distinct advantages of each language and how they can be applied to different types of software development. C++ is often used for performance-critical applications, such as gaming and graphics, due to its speed and memory management capabilities. On the other hand, Java is commonly used for enterprise-level applications, such as web-based applications, due to its portability, scalability, and robustness. By being aware of the technical distinctions between C++ and Java, developers will be better able to make informed decisions about which language is best suited to their software development needs.

Why do we need to know about C++?

C++, commonly referred to as “C with Classes,” was developed in 1985 by Danish computer scientist Bjarne Stroustrup. This programming language has gained international recognition for its complexity and power, and is used to create sophisticated programs such as operating systems and comprehensive software suites.

C++ is a programming language that is object-oriented, multi-paradigm, and provides low-level memory management. It is used extensively in many large corporations, such as Microsoft, Apple, Facebook, NASA, Google, Amazon, and many more. C++ is a powerful language that enables developers to create efficient, high-performance applications.

Because C++ is not tied to any one platform, applications written in it may be deployed across a wide range of environments.

Java: what is it?

In 1995, Canadian computer scientist James Gosling developed Sun Microsystems’ Java programming language. Java is a high-level, open-source and general-purpose language that was designed with an emphasis on minimising the effects of coupling between the language and its implementation. Its WORA (Write Once, Run Anywhere) feature makes it easy to compile Java code on any system.

Java is an attractive choice for developers due to its affordability, user-friendliness, security, portability, and reliability. It is used by professionals to develop software for a range of devices, from game consoles to desktop PCs, from cell phones to servers, from supercomputers to scientific calculators, and even smartwatches. Notable companies such as Google, Airbnb, eBay, Spotify, Slack, Intel, and many more have successfully employed Java in their online applications.

Comparing C++ with Java, what are the key differences?

It is true that C++ and Java share a number of similarities, as both languages have a syntax that is derived from C. However, the two languages differ significantly in terms of their ecosystems. C++ code can be easily invoked from C or C++ libraries, as well as the operating system’s Application Programming Interface (API). On the other hand, Java programming is more effective when combined with other Java-based programs and libraries.

C++’s low-level design and absence of automated memory management also make it a better choice for interacting with hardware than Java.

Listed below are the specific distinctions between C++ and Java:

  • Several Inherited Traits

    Multiple Inheritance is a concept in Object-Oriented Programming which allows a child class to acquire the properties and methods of more than one parent class. While the use of Multiple Inheritance is not allowed in Java, C++ supports a wide variety of inheritance patterns.

    Project safety can be improved through the implementation of type-safety measures, and complex calculations can be carried out during the compilation process. Additionally, the development of a Domain Specific Language (DSL) can be supported through the use of multiple inheritance.
  • Ability to reuse code

    Both the Java and C++ programming languages have implementations of generic classes, which allow for code reuse across multiple data types. C++ templates provide a more powerful and flexible tool for dealing with complex programming tasks. With the use of these templates, developers can create code that can be reused for different data types without having to rewrite the code for each type.

    When working with new data types, C++ compilers can generate specialised functions or classes to facilitate their use. C++ also supports template specialisation, allowing templates to incorporate user-defined functions. Furthermore, certain data types can include customised code based on the parameters of high-level functions.

    The Java programming language does not implement template specialisation, instead utilising a process referred to as “type erasure”. During compilation, compilers for the Java language utilise type erasure, which involves the generation of generic objects that do not contain data types. Despite the fact that type arguments for generic classes are checked during compilation, their behaviour is not.
  • This thought is being reflected on at this moment throughout the run.

    At run-time, developers are able to examine the structure of Java code through a process known as “reflection”. This capability provides programmers with the ability to observe which elements of a class or class type are accessible.

    Rather than providing a true reflection mechanism, C++ makes use of a runtime type information mechanism (RTTI) instead. Through RTTI, developers are not able to gain insight into the members of an object, however they can determine its type.
  • Techniques for Managing Your Memories

    There are two main approaches to managing memory effectively: automatic memory management and manual memory management. For manual memory management, developers need to be mindful of their code, objects, and components in order to manually free up memory that is no longer needed.

    Java’s automatic garbage collection mechanism is an effective way to manage memory allocation, and offers a variety of benefits in terms of security. By automatically releasing memory that is no longer in use, the risk of memory leakage, which can lead to potential weaknesses and vulnerabilities, is greatly reduced. Furthermore, the process of memory management is simplified, as the programmer does not have to manually manage the release of memory, which can be prone to errors and omissions. As a result, Java is able to improve security by reducing memory release mistakes and simplifying memory management.

    In contrast to other programming languages, C++ takes advantage of reference counting through the implementation of “smart pointers”. With this method, when an object is destroyed in C++, its destructor can be used to release the allocated memory.

    While the Java programming language only permits heap allocation, C++ provides developers with the option of both heap and stack allocation. C++’s linear data structures facilitate stack allocation in a manner that is faster, more secure, and simpler than ever before, and also enable the utilisation of the RAII (Resource Allocation Is Initialisation) programming approach.
  • The way it works in practice

    Due to C++’s manual memory management, which differs from Java’s automated garbage collection, C++ generally outperforms Java when it comes to performance. However, in certain scenarios, Java may be able to achieve better performance using Just-In-Time (JIT) compilation. JIT compilation enables code to be compiled at runtime, providing a performance advantage over C++ in certain circumstances.

    Additionally, C++ boasts superior garbage collection capabilities compared to Java, as it requires fewer heap allocations and consumes less memory. Nonetheless, Java is still a speedy and effective way of creating applications, unless low latency is a fundamental requirement.
  • Configuration of builds and packages

    Builders use build and package management to put together their projects and link their software to its many external dependencies.

    Build and package management are aspects of software development that can have a significant effect on developer productivity, project timelines, update management and component tracking. Maven is a Java-based tool that can be used to facilitate the integration of Java projects with integrated development environments (IDEs) such as IntelliJ IDEA.

    At present, the C++ programming community has not come to a consensus on which repository or tool should be used to manage builds and packages. This lack of agreement is further compounded by the fact that certain commercial C++ libraries are only accessible as binary files, which makes it difficult to develop applications using them.


The selection of C++ or Java as the programming language of choice for your projects depends on the specifics of the project. Both languages have their advantages and disadvantages in comparison to each other, and consequently, there is no one-size-fits-all answer that can be provided when it comes to deciding between Java and C++.

Java is an ideal programming language for those who lack experience with low-level principles, providing an accessible and intuitive platform for development. For those who wish to create video games, operating systems, desktop applications and embedded systems, C++ is the perfect choice due to its sophisticated capabilities and powerful tools.
