# Java & Rust Comparison of a Restful Service
2+
3+
This repository showcases two implementations of a restful api service. Its intent is to enable Java practitioners to compare and contrast a web service implemented in both languages. Both servers are reachable and running in production.

## About the tech stacks
6+
7+
### ☕️ Why Java?
8+
Many companies use Java for its ease-of-use and mature libraries.
9+
Java's strongest feature is its object-oriented paradigm that enables developers to model their business logic as a hierarchy of objects.
10+
11+
### 🦀 Why Rust?
12+
Rust earned the top spot as the “most-loved” programming language for the fifth consecutive year of [Stack Overflow’s developer survey]. The Rust ecosystem has recently seen an explosion in adoption with backing from [major companies]. Rust's most unique feature is the borrow checker, a compilation step that validates references and reclaims inaccessible memory thereby eliminating the need for a runtime garbage collector. This enables Rust programs to be blazingly fast and memory-efficient.

2+
3+
## Setup
4+
5+
### Java
6+
7+
Install the Java development kits. Java 11 is required by the Language Support for Java by Red Had VSCode extension.
8+
9+
brew install openjdk@8
10+
brew install openjdk@11
11+
12+
Open VSCode's settings with `Cmd + Shift + P` → `Preference: Open SEttings (JSON)` and add the following settings
13+
14+
```json
15+
"java.configuration.runtimes": [
16+
{
17+
"name": "JavaSE-1.8",
18+
"path": "/usr/local/opt/openjdk@8/libexec/openjdk.jdk/Contents/Home",
19+
}
20+
],
21+
```
22+
23+
For the system Java wrappers to find the JDKs, symlink them.
24+
25+
sudo ln -sfn /usr/local/opt/openjdk@8/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-8.jdk
26+
27+
sudo ln -sfn /usr/local/opt/openjdk@11/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk-11.jdk
28+
29+
30+
31+
Install the package manager.
32+
33+
brew install maven
34+
35+
Install the web server.
36+
37+
brew install tomcat
38+
## Development
39+
Make a build.
40+
41+
mvn compile
42+
43+
Run unit tests run.
44+
45+
mvn test
46+
47+
Make a production build.
48+
49+
mvn package
50+
51+
Clear build artifacts.
52+
53+
mvn clean
54+
55+
Make a production build image.
56+
57+
docker build -t java-car-rentals:latest
58+
59+
Run an ephemeral docker container.
60+
61+
docker run --rm -it java-car-rentals:latest
