How can I pass arguments to main other than String args[] from the console?
The main() method is the entry point to start a Java program. If you relay on input parameters you need to represent them as strings. Use those to instantiate java objects and pass those to the methods which require them. The strings passed to main() may represent a path to...

How can we pass arguments to the main function in JAVA using command prompt and notepad?

1) Sure, that's all fine (except for the argv indices as described below), if you're assuming your inputs are valid numbers. If not, atoi will return 0. 2) You're not meant to pass arguments to main -- instead, you pass arguments to the program, and the OS comes up with...
C++ - Looping main resetting objects
It is probably not a good idea to use recursion to do this task. If you want it to repeat you are probably better off with a while loop. http://msdn.microsoft.com/en-us/library/2aeyhxcd.aspx While(true) will loop as long as the statement (true) is true. Aka forever. You could also do something like while(choice...

Should I test for nullity of values in the args array of Main
As written in your question, the static void Main() is private (because private is implicit if missing). Whoever calls it must use reflection and must know he is walking on tiny ice.

C++ references to main parameters
First of, consider char* to mean c_string, and it immediately becomes obvious why you would need int main(int argc, c_string argv[]) versus int main(int argc, c_string& argv).

From your comments it seems that your command should probably look like java -cp c:\users test so try changing your code to something like Process p1 = Runtime.getRuntime().exec("java -cp c:\\users " + exec); where exec should pass full.package.name.of.YourClass which in your case is most probably test (not test.class or test.java)....

How does function named connect() prevent MPI C program from running?

Is it more efficient to have a print statement in a method besides main or does it matter?
There is no difference in efficiency. This can be seen by the fact that a function can't find out what other function called it. It can't possibly behave in a different way. (Except for stack introspection and inlining...) Architecturally it is better to try to keep methods pure in the...

There is no such thing as "flushing" an std::istream. Flushing is an output concept.
