Objectives

1. Install Java SDK >= 1.7
2. Print the version number to stdout

Instructions

1. Install a recent Java runtime, if you haven't already. We recommend 1.8, but 1.7 will work, too.
2. In com.flatironschool.javacs.Main, we've provided a function getVersion(). It should print your system's current version of Java.
   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.
   2. You might find the following information useful:
      1. You can print information to stdout (usually, your console) with System.out.println().
      2. System.getProperty() will, you guessed it, get a system property (just pass in the name as a String, e.g. System.getProperty("myProperty")).
      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.
      4. Double.parseDouble() converts a String to a Double.

You can run ant or learn-test to test your results. Good luck!
