What is the difference (explicit and implicit parameter in java) ?

Answer 1

Is it okay to do this in C++? I quit Java years back. The principle is the same.

I think you need to understand these terms first.
Explicit: Written in the code. Example:
int main (int argc, char** argv)
Implicit: "Assumed" by the compiler or interpreter. Example:
int main ()
The argc and argv parameters are there, but clearly the programmer won't be using them, however they're mandatory so a modern C++ compiler sorta fills them in for you.

To oversimplify: In real life, 4 + 3 * 2 will be 10, not 14. Because of precedence, there's an implicit parenthesis 4 + (3 * 2) in our sum.

When speaking of implicit parameters, the argc/argv example somewhat illustrates the concept (at least in C++). Hope this helps.
