Java was created in 1991 by James Gosling, and since then has become one of the most used programming languages in the world. After its creation, it took a group of Sun Microsystems engineers 4 years to develop Java. Other than the web and mobile applications, Java is also used in embedded systems, desktop applications, and scientific applications among other things. 3 billion devices around the world including computers, printers, smartphones, kindles, ATMs, home security systems, are using Java programming language.
The Programming Paradigm:
The programming paradigm is the way a programming language approaches a problem to solve it. Java is an Object-Oriented Programming (OOP) language, which means that Java is based on the concept of “Objects”, similar to the real-world objects. An object can have a name, properties, features, or functions associated with it. It can also have its own data, and it can decide how to share that data with other objects. OOP has allowed java to become the industry standard, especially in the enterprise domain. Although Java also supports functional programming, it is mostly used as an OOP language.
Syntax and Features:
Java on the other hand is statically typed, which means that each variable has to be associated with a “type” when it is declared. It makes the job of the compiler a lot easier and also prevents runtime errors, as the compiler can detect the mistakes before the program is executed.
Inheritance is the mechanism by which one entity can acquire the properties of another entity. In Java, a ‘class’ can inherit properties from another ‘class’. It can also inherit from multiple classes, which is called multiple inheritances.
Multithreading:Multithreading in the context of a programming language is its ability to execute more than one part of a program concurrently in order to reduce the execution time of the program by utilizing CPU power.
Java supports multithreading by spawning and executing multiple ‘threads’.
Compilation and execution:
This is one more area where the two languages differ significantly. Java programs are compiled and interpreted to bytecode before they are executed by the Java Virtual Machine (JVM). This makes Java platform-independent, as different platforms can execute the same bytecode with the help of JVM.
