What is JAVA
Java is a programming language and a computing platform. It is used for:
- Mobile applications (Android apps)
- Desktop applications
- Web applications
- Web servers and application servers
- Games
- Database connection
- And much, much more!
To it’s core, JAVA is a object-oriented programming language.
Object Oriented Programming
Object-oriented programming (OOP) is a programming paradigm based on the concept of objects.
Objects are nothing but the instances of classes.
A class is a blueprint for creating objects.
Class defines the properties (attributes) and behaviors (methods) that objects of that class will have.
Benefits of OOP include code modularity,reusability, scalability and efficiency.
How does JAVA work
In the most simple terms,
1. Process of Compilation
The java source code(.java file) is converted to byte code(.class file) by the JAVA compiler(JDK).
2. Process of Interpretation
The byte code is then converted to machine code/native code by the JAVA interpreter(JVM).
Why did I choose JAVA over other languages
To be brutally honest, in my first year of college when I was struggling with choosing one language I scrolled through a few youtube videos, read people’s experience through blogs, LinkedIn posts. All I heard clear your interviews with JAVA and C++. Not being a big fan of C, I decided to go for JAVA.
But with a few months of experience in working with JAVA, I realised it had a vast comunity support, simpler syntax, clear documentation and most importantly no more pointers and memory management(reference languages:C,C++)
Further ahead we will be diving deep into JVM,JDK,JIT.
Stay tuned!😄
