Most people get distracted between choosing programming languages and wandering about whether to prefer Java or not for web development.
Don’t get confused..!!! If you’re planning to develop a web application choose JAVA. As this language provides amazing features and commonly used language across the globe. The primary reason why business prefers is, Java is an independent programming language. It follows ‘WORA’ principle i.e ‘Write Once Run Anywhere’.
Java is a powerful programming language that enforces an ‘Object-oriented programming model‘. The language was developed by Sun Microsystems by James Gosling in 1995. From the past 24 years, Java is developing customized applications that are reliable and effective. Java programming is used for designing every application i.e smartphone, desktop, dynamic and server-side web applications. Additionally, it is used to develop an Andriod application.
It was specially designed to get a look & feel of ‘C++ programming language’. With Java programming language, you can design an application that can run on an individual desktop or amoung distributed network. Besides, it is commonly used to develop a specific module of a webpage.
Java is used in popular enterprises such as Google, Flipkart and Facebook. Sounds interesting right? Yes, therefore Java is granted as the perfect option for other enterprise and also maintainable web development. Hence anyone can simply use Java for developing web applications ad Java is a powerful programming language created ever. Therefore most programmers across the globe are highly passionate to work as a Java developer.
Following are the top 10 reasons to choose JAVA for web development:
The features of Java is also called as ‘Java Buzzwords’.
Simple
It’s no secret Java is a simple programming language. Writing and understanding Java terminology is ease. Whether you’re a beginner or professional developer anyone can learn the concepts of java with no efforts.
As per Sun, Java programming language is easy to understand because:
- Java language is based on C++ syntax. The one who is familiar with C++ can learn Java within a short period.
- There are no complicated concepts such as pointers, multiple inheritance operator overloading and more.
- You don’t need to delete unreferenced objects in Java. Because Java provides ‘Automatic Garbage Collection’.
- Java holds a rich set of Application Protocol Interface.
- The language is short and therefore you can easily become fluent.
Object-oriented programming
If you’re a beginner to Java then you must understand about OOPS concept before going further. Many people say ‘Java is object-oriented programming language’, what it actually means?
As the name suggests “Object-oriented programming”, it refers to a programming language that uses objects while developing.
OOP endeavours to implement real-world entities such as
- Class
- Object
- Method
- Inheritance
- Abstraction
- Polymorphism
- Encapsulation and
- Message passing in programming
Although C++, C# and Ruby languages follow an object-oriented programming model, Java implements in an effective way. An object-oriented application in Java is purely depended upon declaring classes, creating multiple objects from classes. As a result, interacting between these objects.
Platform independent
Many people get confused – is Java is platform-independent or not? The answer is YES. Java is a platform-independent language.
What is meant by platform-independent? Source code can execute on every operating system such as Windows, Linux and Mac. Java is the only language that can run on all OS.
There are two types of platform such as
- Software-based platform
- Hardware-based platform
Basically, any program that is written by a human is called source code. As human develops the program, it contains words, phrases, syntax and more. Unfortunately, machines don’t understand human language. Therefore programmers compile the source code language to machine level language.
A compiler is a process to translate complete source code for another programming language into executable code.
Now, this executable code can be a set of a machine instruction, it can be executed by CPU. Sometimes, the code can be interpreted by a virtual machine. It is called as ‘Java Byte Code’.
Step by step execution procedure of the Java program
- You’ve written a program in Java.
- The program will be complied with ‘Javac’.
- The result of the javac (Java compiler) is the .class file. This file is known as bytecode.
- The .class file cannot be executed. Therefore you require an interpreter to run .class file.
- Thus JVM (Java virtual machine) is an interpreter. That JVM will execute the bytecode.
- Finally, the program executes with the desired output on the screen.
Rich API
One more reason for the success of Java is – Rich API. Java has an ultimate set of API’s. These API’s are cost-effective and easily available for Java programmers across the globe.
The Java API is a collection of pre-defined classes that are included with the JDE (Java Development Environment). These classes can be written in Java and execute on Java Virtual Machine.
These Java Application Program Interface can be used for
- I/O
- XML parsing
- Utilities
- Database connection
- Networking
Most programmers & web development industries prefer Java among all the languages. Because these API’s can make designing a product cost-effective and flexible.
Security
Will you download a picture that consists of a virus? Never right. Nobody encourages virus, hackers and other unauthorized parties. Taking java into consideration, this language provides high security for web developers.
Java is well-know for its high standard security. With Java programming language you can easily develop virus-free applications. A web developer worries less while developing an application with Java. Since Java is highly safe and secured. Few features include access control, cryptography and more. These secured features allow programmers to make use of a comprehensive API. It includes digital signatures, cyphers, secured login, etc.
Java is safe and secure because
- No explicit pointer
- Java programs execute inside Sandbox (Java virtual machine)
Here Java virtual machine in java utilises sandbox. This ensures the security feature in Java.
Multi-threading
Multithreading includes a process of executing multiple threads at the same time.
What is a thread?
A thread is defined as a light-weight process or a small unit of processing. As a result, multiprocessing & multithreading are used to achieve multitasking.
It’s no secret developer prefer multithreading over multiprocess. Because when you execute a thread, they use a shared memory location. That means every time when they execute they don’t allocate an internal memory. Ultimately saves memory. The context-switching from one thread to another can take very less time compared to the process.
Java multithreading is commonly used in graphics, animations, video games, etc.
Advantages of multithreading
- It doesn’t block any users. Since threads are individual and perform various operations concurrently.
- You can execute multiple tasks and save time.
- Threads are independent. If a thread doesn’t execute, it doesn’t affect on other threads.
Java is implemented with multi-threading functionality. It enables applications written in Java programming to execute multiple threads identically. The concept of multithreading gives it easy and simple for java developers, as they don’t need to waste their time and effort by creating a wide range of instructions for the corresponding hardware.
It presents users with
- Multiple operations
- Effective responses
- Best performance
Robust
Simply put, robust means strong. It is extremely supported language. Exceptions instead of coding errors. There are few exceptions that are generated through a virtual machine such as “NullPointerException” rather than endeavouring to overwrite memory. That means, exceptions provide stack traces, these are used for debugging.
- Java uses powerful memory management.
- Strong type checking
- No pointers concept is included that avoids security issues.
- The automatic garbage collection that runs on JVM can get rid of objects.
- There are exception handling (try, catch) and type checking process.
- Java has a two-time execution mechanism. It means compilation & interpretation.
Portable
Java is portable. It allows you to execute the java programming on any operating system. That means Java doesn’t need any implementation.
Generally, Java is well-know for portability, it appears from architecture-neutrality. In other programming languages such as C/C++, source code can run differently on different operating systems. Because of how these platforms execute arithmetic and other mathematical operations. In Java, it has been purely clarified.
Distributed
Many developers say – Java is distributed. With Java language, you can design distributed applications. Considering java, RMI & EJB are used to create an effective distributed applications. Here multiple clients rely on multiple servers. Whenever a system encounters an error in one server doesn’t reflect on client systems.
Dynamic
Do you know this attractive feature of Java – Java is a dynamic programming language. Because Java supports “dynamic memory allocation” due wastage of memory has been reduced drastically. As a result, it improves the performance of your web application. The method of allocating the memory space to the information of the java code at run-time is called “dynamic memory allocation”.
