# Contributing to Learn.co Curriculum
2+
3+
We're really excited that you're about to contribute to the [open curriculum](https://learn.co/content-license) on [Learn.co](https://learn.co). If this is your first time contributing, please continue reading to learn how to make the most meaningful and useful impact possible.
4+
5+
## Raising an Issue to Encourage a Contribution
6+
7+
If you notice a problem with the curriculum that you believe needs improvement
8+
but you're unable to make the change yourself, you should raise a Github issue
9+
containing a clear description of the problem. Include relevant snippets of
10+
the content and/or screenshots if applicable. Curriculum owners regularly review
11+
issue lists and your issue will be prioritized and addressed as appropriate.
12+
13+
## Submitting a Pull Request to Suggest an Improvement
14+
15+
If you see an opportunity for improvement and can make the change yourself go
16+
ahead and use a typical git workflow to make it happen:
17+
18+
* Fork this curriculum repository
19+
* Make the change on your fork, with descriptive commits in the standard format
20+
* Open a Pull Request against this repo
21+
22+
A curriculum owner will review your change and approve or comment on it in due
23+
course.
24+
25+
# Why Contribute?
26+
27+
Curriculum on Learn is publicly and freely available under Learn's
28+
[Educational Content License](https://learn.co/content-license). By
29+
embracing an open-source contribution model, our goal is for the curriculum
30+
on Learn to become, in time, the best educational content the world has
31+
ever seen.
32+
33+
We need help from the community of Learners to maintain and improve the
34+
educational content. Everything from fixing typos, to correcting
35+
out-dated information, to improving exposition, to adding better examples,
36+
to fixing tests—all contributions to making the curriculum more effective are
37+
welcome.

# cs-hello-world-lab
2+
3+
## Objectives
4+
5+
1. Install Java SDK >= 1.7
6+
2. Print the version number to stdout
7+
8+
## Instructions
9+
10+
1. Install a recent Java runtime, if you haven't already. We recommend 1.8, but 1.7 will work, too.
11+
2. In `com.flatironschool.javacs.Main`, we've provided a function `getVersion()`. It should print your system's current version of Java.
12+
1. We want not only to make this function work but also to make sure that it prints a version compatible with the upcoming lessons.
13+
2. You might find the following information useful:
14+
1. You can print information to stdout (usually, your console) with `System.out.println()`.
15+
2. `System.getProperty()` will, you guessed it, print system properties.
16+
3. The system properties `"java.version"` and `"java.specification.version"` will both return your system's current version of Java. The former, counter-intuitively, is more specific, and you might need to manipulate the `String` that it returns a bit more.
17+
4. `Double.parseDouble()` converts a `String` to a `Double`.
18+
19+
You can run `ant` or `learn` to test your results. Good luck!
