System.out.println("\nThere were " + iArgumentCount + " command line " +
((iArgumentCount != 1)? "arguments":"argument") + ".");

This line in an program we are trying to disect (for school). Uses a ? and what looks like an if statement. Can you help explain this to me?

Thank You.

Its a ternary statement.

Same as:

String args = null;
if (iArgumentCount != 1)
{
   args = "arguments";
}
else
{
   args = "argument";
}
System.out.println("\nThere were " + iArgumentCount + " command line " + args + ".");

a = b ? c : d; is shorthand for if ( b ) a = c; else a = d;
