Chris Jesz 8b4c2f3d03 Added a more detailed example and corrected some content. (#22716) ... The original page showed java.io as a built in package but it really isn't in the sense that you have to import the package in order to use it where as java.lang does not need to be imported. I removed mentions of java.io and cleaned up the description. I also added a simple example and explanation of a couple of java.lang packages.		2018-11-25 11:16:42 -07:00
