Fail when trying to get another property? -resolved by OP

Working in Systemizer.java file. I looked thru the properties as listed out by the 'for' loop and picked another property to print out with the following code.

System.out.printf("The Java version is: %s %n", 
    System.getProperty(java.class.version));

When I run it I get the following error:

com/teamtreehouse/Systemizer.java:18: error: cannot find symbol
    System.getProperty(java.class.version));

symbol: class java
location: class Systemizer

Please let me know why this is failing? It looks to be correct when compared to the first line Craig added to the code in the video.

Also of note: the 'class' word in the failed line of code is highlighted red; unlike when 'class' is used in the first "java.class.path"... And I believe I just fixed my own problem by seeing I didn't put the quotes "" around the java.class.version... ugh!

I will leave this post as it might help another new programmer struggling to remember proper line structure.

The corrected code is as follows:

System.out.printf("The Java version is: %s %n",
    System.getProperty("java.class.version"));
