Chapter 1: Introduction to Java
Java is a versatile, platform-independent, object-oriented programming language known for its 'write once, run anywhere' capability. It combines both compilation and interpretation to enhance performance and portability, with core components including the JDK for writing, the JRE for running, and the JVM for executing applications. Its structured programming style focuses on classes and methods, making it suitable for various applications from desktop to mobile.

What we have learnt
- Java is a high-level, object-oriented programming language developed by Sun Microsystems.
- It features a unique combination of compiled and interpreted languages for performance.
- Java's core components include the JDK, JRE, and JVM, with a focus on classes and methods.
Key Concepts
- -- Java Development Kit (JDK)
- A software development kit used to develop Java applications, inclusive of development tools and JRE.
- -- Java Runtime Environment (JRE)
- An environment that allows Java applications to run, which includes the JVM and core libraries.
- -- Java Virtual Machine (JVM)
- It interprets and executes compiled Java bytecode, making Java platform-independent.
- -- ObjectOriented Programming (OOP)
- A programming paradigm based on the concept of 'objects' which can contain data and methods.
- -- Write Once, Run Anywhere (WORA)
- A main feature of Java allowing code to be executed on any platform with the JVM.
