Is
java -ea -dsa
the same as
java -ea
?
the KnB book says the java -ea enables assertions in all classes, except for the system classes, so my impression is that the first one is doing the same...
any ideas?

Have you had a look at the Java application launcher tool docs?
Maybe there is some interesting info there

Should I memorize the different assertion options? The only one my book covers is -ea (-enableassertions).

Sorry Brian did I confuse you. Well I only wanted to pointed out the order of evaluation of the assertions command line arguments, it's left to right so if you say java -enableassertions -disableassertions <filename> then assertions would be disabled. As for the various assertions command line options they are :
-ea or -enableassertions
-da or disableassertions
-esa or enablesystemassertions
dsa or disablesystemassertions
Try this javaranch
