How you got this question??
You can NEVER print some statement anywhere without invoking main(). All understand the nature of the question here and was immediately able to come up with the answer, however, you have to realize that at some point, the program has to have an entry point, or a main()--even if it's not coded in this particular class (i.e. SCWCD). If there is another class with main() that merely uses SCWCD, then yes, the static block initializer or static class variable are loaded and print is executed. Nonetheless, there must be main() somewhere.
