Java and C++: Why Does Google Mainly Use Them?

Google would hire both Java and C++ programmers, with equal skills. Really!

However, does Google prefer, on the margins, C++ to Java?  Probably not! In some ways, Java is easier than C++ in an interview because you will not have to worry about memory management and pointers. Furthermore, if you don’t know C++, you will have difficulty understanding computer architecture as well.

These both are most used at Google. It is difficult to choose between the two. But, more importantly, languages are not that important. Since there are a lot of differences between Java and C++.

Would it be better to switch from one language to another? Definitely not!  You’d probably be wasting your time. Your skills matter the most. For instance, you are good at coding with Java and also have the core knowledge of C++. But, the top tech companies always hire the best candidates only. Similarly, Google hires the best candidates with a high potential of playing with the most complex programming algorithms.

What makes Java so popular?

Java’s platform independence is one of the reasons it is so popular. The Java Runtime Environment (JRE) is necessary for Java programs to run on different types of computers. As long as the computer has a Java Runtime Environment (JRE) installed, Java programs can run.

Java Runtime Environments are compatible with most types of computers, including Windows, Macintosh, Unix, and Linux, as well as large mainframe computers, smartphones, and tablets.

The world’s largest companies use it and it has been around for so long using it.

What are the benefits of learning Java?

The popularity of Java is not declining and, for that reason, the language is still worthwhile learning. It’s relatively easy to learn, which makes it the first programming language picked up by most developers.

Its syntax is similar to English, with a small number of special characters, so Java could be learned in a short period of time and used to build apps. Therefore, learning Java is extremely useful when learning any of the other two languages mentioned above. According to him, the language has many potential applications such as:

• Developing Android applications

While Android applications can be developed in other ways, the majority of them are built in Java, using the Android API. Android uses different JVMs and packaging methods, but most will still be written in Java.

• Java web applications

Applications built in Java are commonly found in government, healthcare, insurance, education, and defense departments. Google’s Gmail is a good example.

• Software tools

Java is used for writing and developing useful software and development tools, such as Eclipse, IntelliJ IDEA, and NetBeans IDE.

• Scientific applications

It has a number of advantages over other languages, including safety, portability, maintainability, and better high-level concurrency tools than C++. Java can lead you down different career paths based on your career prospects. No matter what kind of application you want to build – games, mobile applications, desktop applications, or web apps – Java can handle it all.

Even if you do not plan on using Java in your career or job role, you will learn syntax, ideas, patterns, tools, styles, and idiosyncrasies that can easily be transferred to other programming languages.

When you learn Java, you will gain greater insight into how one language performs certain operations in comparison to another. You will become an even more well-rounded developer if you know what works for Java and other languages.

History and Origins of C++

Dennis Ritchie from Bell Labs created a Unix language called C in 1972. Denmark’s Bjarne Stroustrup added classes to C in 1979. To create C++, he added object-oriented features. To make the language easy to program large software systems but also fast with low-level hardware control like BCPL, he attempted to create a language much like Scala. In addition to being more flexible and efficient, C++ offered him more advanced features than C. By the 1990s, C++ had grown and developed, becoming the first choice for operating systems such as Windows, BeOS Haiku, and Syllable.

C++ has many advantages

The C++ language has the flexibility to be used for procedural, object-oriented, or functional programming, thus being called a “multi-paradigm” language. Its flexibility and extensibility make it a popular programming language. A procedural language allows modules to communicate via shared data stores through writing and reading of state.

By sending various messages to other objects, objects communicate with tightly bound object-oriented languages. Polymorphism simplifies code by allowing the deployment of one interface and many entities. Compared to most other languages, C++ code runs faster.  Additionally, it offers classes, data abstraction, polymorphism, encapsulation, and inheritance as well as a useful function library.

Used in a Variety of Fields

The C++ programming language is used for tasks requiring high performance, such as video editing, transcoding, computer-aided design (CAD), image processing, games, telecommunications, and business. Google for Chrome and other apps, Reuters and Bloomberg for data feeds with low latency, and Microsoft for Office are some of the companies using it.

C++ is also used by many airlines for flight control systems. C++ is used to create games for Xboxes and iPhones with the Torque 3-D game engine. The makers of advanced medical equipment use C++ for their mission-specific software APIs, as do defense contractors. Ever-note, LinkedIn, Microsoft, Opera, NASA, and Facebook are well-known companies and organizations that use C++. In order to make HTTP/REST requests, LinkedIn uses rest-client-CPP, a C++ client. It is used by Facebook for back-end services, and C++ standards are frequently modified to include custom features.

Conclusion

Depending on the objectives of the project, programming languages offer different advantages. Python, Java, and C++ are popular at Google, for instance. Here are their comparisons:

Algorithms used in both languages are quite the same in terms of working but the usage and the syntaxes are totally different. The result is that C++ has many cross-platform libraries since each platform has its own compiler. Java programs can run on any device that supports Java since the Java Virtual Machine is essentially an abstraction layer. Java programs are memory safe while C++ programs are not. C++ relies on unchecked castings and a developer’s memory management while Java has a disciplined system for detecting errors. Java provides multiple inheritances through interfaces, while C++ offers multiple inheritances through classes.
