Java Vs C++

Today we will see an in detailed comparison between two prominent programming languages namely, Java and C programming. To develop your logic, best Java institutes in Pune often teach basics of ‘C & C++’ language along with Java training.


Let us see how Java differs from C++

Java is a genuine object oriented language, while C++ is essentially with object oriented extension. That is the thing that precisely the increment operator ++ demonstrates. C++ has kept up in reverse compatibility with C. It is in this way conceivable to compose an old style C program and run it effectively under C++. Java gives off an impression of being like C++ when we consider just the “extension” some portion of C++. Be that as it may, some object oriented features of C++ make the C++ code to a great degree hard to take after and keep up.

Points of differences between Java and C++

  • C++ makes use of pointers
  • Pointer creation and usage in Java is not permitted.
  • Memory allocation and deallocation has to be taken care of by the programmer in C++.

  • This task will be taken care of by JVM in Java.

  • C++ consists of the goto statement.

  • Java doesn’t consist of the goto statement.

  • Multiple inheritance directly available in C++

  • Java lacks multiple inheritance, but you can achieve it by various means.

  • Constructors and destructors are there in C++

  • Java consists of only constructors. Java does not have destructors.

Benefits of Java over C++:

  • One clear advantage is a runtime environment that gives platform freedom: you can utilize similar code on Windows, Solaris, Linux, Macintosh, etc. This is surely essential when programs are downloaded over the web to keep running on an assortment of platforms.

  • Garbage collection:

Java is known for its garbage collection. Garbage Collection (GC) is a type of programmed memory management. The garbage collector endeavors to recover junk, or memory, possessed by objects that are no more being used by the program. This takes out the issue of manual memory allotment. In this way, Garbage collection prompts bring down bug number and quicker execution time. While in C++, a noteworthy bit of C++ code is devoted to memory management. Cross-component memory management does not exist in C++. Libraries and components are harder to manufacture and have less regular APIs.

  • Performance:

In spite of the fact that performance is normally not considered one of the advantages Java has over C++, garbage collection can make memory management significantly more productive, consequently affecting execution. Likewise, Java is multi-threaded while C++ does not bolster multi-threading. C++’s thread safe smart pointers are three times slower than Java references. What’s more, Java has HotSpot Java Virtual Machine (JVM), which highlights in the nick of time (JIT) compilation for better execution.

  • Portability:

As Java’s mantra has been “Compose once, run anyplace,” Java is portable with next to no exertion. C++ is portable in principle, however by and by, you need to assemble another language (#ifdef’d sorts, and so forth.) on top of it. Furthermore, C++ has huge contrasts from vendor to vendor, e.g., standards support.

  • Security:

Java dispenses with pointers, which can permit arbitrary memory access to and the capacity to effortlessly crash the procedure (core dump). There are no buffer invades in Java, and code and data can’t be unintentionally blended. What’s more, Java incorporates limits checking. Limits checking is any method for distinguishing whether a variable is inside a few limits before its utilization.

Thus, we saw a comparison between C++ and Java, in this blog. Also, we saw benefits of Java over C++. Take admission to a Java institute in Pune, and be ready for a bright career ahead.
