What is Java?
Java is a programming language introduced in 1995.
A Quick Intro
In Java every application always start with a class name. Java is a object oriented programming language that is designed to have a fewer dependancies implementations as possible. It allows developers to Write once and run everywhere(WORA) meaning that complied Java code can run in all platforms that support Java without having to recomplie again.
Key Java Features
Simplicity
Java is renowned for its simplicity, making it an ideal language for both beginners and experienced developers. Its syntax, inspired by C/C++, is easy to learn and comprehend. Java avoids the complexities of features like pointers, go-to statements, and multiple inheritance, promoting clean and understandable code.
Platform Independence
One of Java’s groundbreaking features is its platform independence. The Java compiler converts source code into bytecode, which can be executed on any platform with a Java Virtual Machine (JVM). This cross-platform compatibility allows developers to write code on one machine and run it seamlessly on various operating systems, including Windows, Linux, and macOS.
Object-Oriented Programming (OPP)
Java follows the principles of Object-Oriented Programming, organizing programs into objects and classes. The four main concepts of OOP — abstraction, encapsulation, inheritance, and polymorphism — are integral to Java’s design, fostering modularity, reusability, and maintainability in code.
Security
Security is a top priority in Java, making it a preferred choice for developing secure applications, such as those in the banking sector. Java’s design eliminates the use of pointers, preventing unauthorized access to variables. Additionally, Java includes features like garbage collection, exception handling, and memory allocation, minimizing security vulnerabilities like stack corruption and buffer overflow.
