We have C++ in the corner. This is the C language with the best classes for writing system level code, he was created by Bjarne Stroustrup in 1985. In the other corner is the Java programming language, developed by Sun Microsystems with a mantra.
“Write once, run anywhere.”
Which language is right for your software project?
You may have done a bit of research to find the right language, but it’s hard to tell which language is right for someone without software development experience.
Both Java and C++ have been in production for years. Both have similar syntax, support object-oriented programming (OOP), and run some of the largest enterprise platforms on the market. Most C++ programmers will tell you that the style and syntax are very similar, so it’s easy to convert to a Java project.
But despite their similarities, the two languages are worlds apart. Java is an interpreted language and C++ is a compiled language. This diversity will play a big role in future projects. In this article, we’ll look at the main differences between Java and C++. What is the difference between Java and C++
A common misconception is that a language that is similar to another language should also be functionally similar. Although Java and C++ have similar syntax, they are very different in how they are executed and processed.
interpreted and compiled
Java is an interpreted language. That is, it is “translated” into a binary file at run time. This allows it to run on any operating system regardless of where it was created. C++ is a compiled language. That is, a program is compiled on a specific operating system and will only run on that specific operating system. If you want compatibility with another operating system, you should compile the program on that operating system.
memory management
Java, like most high-level programming languages, supports garbage collection for automatic memory management. In C++, memory must be managed manually using specific operators and pointers.
memory safe
Java is a memory-safe language. In other words, if you try to assign a value other than the specified array parameter, the programmer will get an error her message. C++ is much more flexible, but it comes at a price. C++ allows programmers to assign values outside of the allocated memory resource, which can later lead to runtime errors or fatal crashes.
speed and performance
Java is popular among developers, but it’s also slow because the code has to be interpreted at runtime. C++ compiles to binary, so it runs instantly and faster than Java programs.
Multithread
The difference between C++ and Java regarding multithreading is the level of abstraction available to facilitate writing concurrent programs. As a low-level language, C++ did not receive standard library support for multithreading until C++11. Before that, managing POSIX threads or pthreads in C was a chore. Java has long provided more tools and built-in features for writing concurrent code. However, since C++ is closer to the hardware, performance is slightly better here.
pointer
A pointer is a C++ construct that allows you to manage values directly in a memory region. Java does not support pointers, so you can only pass values using value references.
name space scope
C++ has both global and namespace scope, allowing data and functions to exist outside classes. Java follows a root hierarchy of single inheritance, so there is no namespace scope.
