More over how many engines mysql server has and what is the default engine?
The Java contruct for main() is the equivalent of C’s “void main(int argc, char **argv)”. Java’s main() receives an array of strings, from which one can obtain the length with args.length; no need for argc, the count. It can also be written “String args[]”; both ways specify an array of strings.
