PROGRAMING LANGUAGE DIFFERENCES BETWEEN C++ AND JAVA
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).
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.
