Programming Language Differences Between C++ and Java – Desiliciouskitchen


Desiliciouskitchen-The difference between the Java programming language and the C++ programming language can be traced to the inheritance system, because they have different design goals:

  • C++ is designed primarily for programming systems, developing the C programming language. For this reason, programming language procedures are designed for more efficient program execution, C++ has added support for object-oriented programs with static types, except in terms of control, including resource management and programming. generic, in particular also added “standard library” including algorithms and generic program content.
  • Java was originally designed to support computer networks. Java is believed to be a secure and very easy virtual machine. Java is bundled with an extensive design library to provide a complete abstraction of a platform. Java is a static type object-oriented programming language that uses a syntax similar to the C programming language, but is not compatible with it. Java was designed from the ground up, with the aim of being easy to use and accessible to a wider audience.

Differences Of Its Development Objectives:

The difference in the purpose of developing the Java programming language with the C++ programming language, results in differences in principles and design differences between each of these programming languages.

  • More or less compatible with the source language (source code) C language.
  • Allows direct calls to native system libraries.
  • Run with low security system facilities.
  • Supports unregistered arithmetic.
  • There are no standard or size limits for all types of numeric data types. Only given relative sizes.
  • Parameters used can be values, pointers or references.
  • Memory management through a third party that provides garbage collection (garbage collection).
  • The C++ Standard Library has more settings and functions than the Java standard library.
  • Multiple inheritance.

  • Designed from scratch not compatible with any programming language.
  • Calls via the Java Native Interface.
  • Runs on a secure (protected) virtual machine.
  • Does not support unregistered arithmetic.
  • Standard and size restrictions for all data types.
  • Parameters used are always with value, even though objects accessed through references will be changed to value first, not directly from the object.
  • Automatic garbage collection, although it can be manually set by the programmer.
  • The Java Standard Library evolves with each release/version.
  • Single inheritance, if needed multiple inheritance can only be through the interface.

The C++ programming language is powerful but complex, while the Java programming language is designed to be simpler (and therefore easier to learn).

General Differences:

In Java, dynamic memory management and pointers are done automatically. This automation eliminates the possibility of using pointers that can destabilize programs and the operating system. In C/C++ programmers do their own memory allocation and deallocation.

  • Java does not recognize multiple inheritance as in C/ C++. Multiple inheritance in C/C++ is confusing and makes it difficult to build applications and compilers. Instead of something better, Java uses interfaces.
  • Java uses pure OOP language while C++ is a hybrid OOP language (can use both OOP and procedural models).
  • Java uses the Exception model in handling program errors.
  • Java does not use compiler-directives in the source code.
  • Java has a garbage collection facility that works automatically to ensure memory availability by freeing up unused memory.
  • Java is very portable, both source files and compilation results. This is different from C/C++ which is only portable at the source code level, and even then by codifying when moved to a different platform.
  • Java language and implementation specifications are defined and do not follow a particular machine or platform. This is different from C / C + + which is very dependent on the machine and platform that will be used.
