You need to find a good java  introductory book.

Test.java:

public class Test
{
public static void main(String[] args)
{
for (int i = 0; i < args.length; i++)
System.out.println("Argument " + i + ": " + args[i]);
}
}

If you want to learn Java, forget the C or C++, Read any Java book
without comparing with C and you will understand . C is old and not
good realized Language. C can do any things but it isn’t understandable
language.

I don't agree with you at all here. Much of the syntax and structure
in Java was derived from C. So basically anyone that knows C should
be able to learn Java MUCH faster than someone that doesn't know any
language. I coded with C/C++ for many years before learning Java and
I found it to be a fairly smooth transition. The only thing that is
REALLY different is the mindset of OOP.

I would have to agree, I do mostly Java coding here but on occasion we
do C++ stuff. It all comes down to the best tools for the job, and
sometimes c/c++ is the best tool for the job.
