# Java Jump Start
### A powerful language demystified.
---
Java Jump Start is a comprehensive guide designed to help you quickly learn
the amazing abilities of Java. This guide will provide you will all the
essentials in syntax as well as the unique features of Java.
---
## Get Started
### Easiest Option
You can create a GitHub Codespace under the green Code button. This will
create an IDE for you in the browser.
#### Create a Codespace with Code Button
#### Load the Codespace Environment
```bash
bash ./init_codespace.sh
```
```bash
source ~/.bashrc
```
### Most Customizable Option
Clone the repository to your local machine using the following command.
```bash
git clone https://github.com/theoliverlear/Java-Jump-Start.git
```
### Run the Java Code
Running the Java code, with modern Java, only requires the `java` command.
#### For all files, except `Script.java`, run:
```bash
java ExampleFile.java
```
#### For `Script.java`, run:
```bash
java --enable-preview Script.java
```

### Chapter 0: Introduction
- What is Java?
- Java is a high-level, object-oriented programming language that is
designed to run anywhere at anytime, securely.
- Why Java?
- Java is fast, secure, and well-maintained with many libraries still used
in enterprise like Spring Boot.
- What is a compiled language?
- Java, as a compiled language, is converted into bytecode before any
execution. This bytecode is then run on the Java Virtual Machine (JVM).
