The C language, which is quite simple, is not tied to any particular hardware or system. This makes it easier for a user to write programs that will run without many or any changes on practically all machines. The C language is often called a middle-level computer language as it combines the elements of high-level languages with the functionalism of assembly language.
Java is a general-purpose, concurrent, class-based, object-oriented programming language that is designed to minimize implementation dependencies. It relies on a Java virtual machine to be secure and highly portable. It is bundled with an extensive library designed to provide a full abstraction of the underlying platform. It includes a documentation system called Javadoc. The differences are as follows:. It can also be done using the internal API sun. Unsafe but that usage is highly discouraged and will be replaced by a public API in an upcoming Java version.
Although they were created to solve similar kinds of problems, and have similar syntax, they are quite different. For example:. Given the very different natures of the languages, definitive qualitative differences are also difficult to draw.
In a nutshell, there are inherent inefficiencies and hard limits on optimizing in Java, given that it heavily relies on flexible high-level abstractions, however, the use of a powerful JIT compiler as in modern JVM implementations can mitigate some issues.
Being an open committee, anyone is free to join, participate, and contribute proposals for upcoming releases of the standard and technical specifications. The committee now aims to release a new standard every few years, although in the past strict review processes and discussions have meant longer delays between publication of new standards , , and The Java language is defined by the Java Language Specification ,  a book which is published by Oracle.
The Java language continuously evolves via a process called the Java Community Process , and the world's programming community is represented by a group of people and organizations - the Java Community members  —which is actively engaged into the enhancement of the language, by sending public requests - the Java Specification Requests - which must pass formal and public reviews before they get integrated into the language.
The lack of a firm standard for Java and the somewhat more volatile nature of its specifications have been a constant source of criticism by stake-holders wanting more stability and conservatism in the addition of new language and library features.

Sun Microsystems. Some programmers and unfortunately even some book authors claim that the Java programming language uses call by reference for objects. However, that is false. Because this is such a common misunderstanding, it is worth examining a counterexample in some detail This discussion demonstrates that the Java programming language does not use call by reference for objects.
Instead object references are passed by value. Java for Programmers. Prentice Hall. Unlike some other languages, Java does not allow programmers to choose pass-by-value or pass-by-reference—all arguments are passed by value. A method call can pass two types of values to a method—copies of primitive values e. Objects themselves cannot be passed to methods. GNU Foundation. Retrieved 20 April Microsoft Corporation.

These two computer programming languages are very popular because of their wide applications. So anyone who is new to programming is generally recommended to learn any or both of these languages before moving on to other languages and technologies. It was also known as C with classes. Besides the OOP features, it has all the features of the C language. Besides giving you high-level features, this language also allows you to perform low-level memory manipulation.

Clear linking rules are abided to meet reference reputability standards. Only authoritative sources like academic associations or journals are used for research references while creating the content. If there's a disagreement of interest behind a referenced study, the reader must always be informed. Naturally, both seem like great options for someone who plans to begin learning to code.
Views C is a successor of B language which was introduced around C is a structured language which is easy to learn and produces efficient programs. It can handle low-level activities and can be compiled on a variety of computers. Today C is the most widely used System Programming Language.
It encapsulates high and low-level language features. So, it is seen as an intermediate level language. Earlier it was called "C with classes" as it had all the properties of the C language. What is the Java language? Java is programming language developed by Sun Microsystems. A small software development team developed this language. They were known as the Green Team, who initiated Java language in the year
