Answer / sunitha
In C and C++ when you invoke a program, the system passes
two parameters to it:
argc--the number of arguments on the command line
argv--a pointer to an array of strings that contain the
arguments
When you invoke a Java application, the system only passes
one parameter to it:
args--an array of Strings (just an array--not a pointer to
an array) that contain the arguments

argv--a pointer to an array of strings that contain the
arguments

if passes the arguments in an array of Strings if and only if the arguments are given by the user.
otherwise system does not pas any argument.
