Hi there ,

I am starting with java learning and by testing the examples you mentionned
in "jls8-diif.pdf" page 44 and instead of an output "
-727379968
1000000000000
"


here what i got instead ,

Exception in thread "main" java.lang.UnsupportedClassVersionError: Test0 :
Unsupported major.minor version 51.0
