What is Java?
Java is an object-oriented programming language that runs on the Java Virtual Machine (JVM), which allows you to write platform-independent programs. Java is used for both client-side and server-side programming, but it is primarily utilized in server-side programming in online applications.
JVM is a machine that converts bytecode into machine code. Byte-code is an intermediate code created by translating source code. Unlike machine code, this code runs exclusively on the JVM and is interpreted by the many computers that Java programs run on, such as Linux, macOS, and Windows.
Advantages of Java
- Java’s compilation and interpretation portability features allow it to be written once and run anywhere. All you have to do is write the source code, which will be transformed into bytecode on the JVM and interpreted on any system or OS.
- Multi-threading is supported by Java. It signifies that Java can handle multiple jobs at the same time. A thread is a unit of a process in Java, and it is possible to run numerous threads at once.
- Java is one of the most secure platforms for designing and executing applications due to its capabilities.
- JS allows you to rapidly develop code due to its execution directly in the browser. It minimizes support from the server for even the basic and simple calculations that increase efficiency and save time.
There are many grounds on which the two popular programming languages differ. Let’s understand each one by one:
1) Typing Discipline
2) Language Type
4) Datatype Definition
5) Role in Web Development
Java is used for developing the backend. Although JS was initially developed for building the frontend, it can now also be used for developing the backend using NodeJS.
6) IDEs and Code Editors
Java IDEs include Eclipse, NetBeans, and IntelliJ IDEA, to name a few. Some of them are completely free, while others are reasonably priced for the value they bring. Like Java, all of these programs run on a variety of platforms.
7) Object Creation
8) Code Clarity
All of Java’s variables are encapsulated in a single type. When you declare an object or create a variable of a set primitive type, that variable is locked into its identity. You won’t be able to run your code until the problem is fixed if there are any mismatches.
Multithreading in Java allows for and assures concurrency, making the program run more quickly and efficiently. JS does not handle concurrency or several events at the same time.
10) Error Detection
Compilable languages, such as Java, check the code of a complete project while optimizing and converting scribbles into byte code that the Java Virtual Machine can then read. It detects a significant percentage of syntactical errors and alerts developers at build time.
Java was created with the primary objective of ensuring the security of source code. It also comes with a slew of features to back it up.
|Point of distinction||Java|
|Typing discipline||Java is a strongly-typed programming language.||It is weakly typed.|
|Creator||James Gosling (original), Sun Microsystems (current)||Brendan Eich and Netscape|
|Datatype definition||Data types are mandatory to be defined in Java.||There is no compulsion of defining data types in JS.|
|Role in web development||Java is used for backend development.||It can be used for both frontend and backend development.|
|IDEs and code editors||Eclipse, NetBeans, and IntelliJ IDEA are the major IDEs for Java development.||Most IDEs and code editors provide support for JS. Popular ones are Brackets and Atom IDE.|
|Object creation||Once a class is declared in Java, it creates objects.||JS creates objects from a prototype object.|
|Code clarity||It has high code clarity.||Code clarity is average.|
|Concurrency||It supports multi-threading.||Multi-threading is not available.|
|Error detection||Java finds errors during the build time.||JS detects errors at runtime.|
|Security||Security is the primary objective of Java. For the same, it comes with a plethora of features.||There is no built-in security in JS.|
In this blog, you came across two of the most powerful languages used in software development but in different ways.
Java’s powerful typing and compilation capabilities will free you up to focus on developing excellent coding habits, while a mostly auto-configured development environment will get you writing, testing, running, and, most importantly, delivering your code quickly.
