Var args

[Pawan Arora]

what's the meaning of varargs? Is it like [B]method(int... args)[/B] where this method can have any no. of parameters.

Basically, yes. And the identifier references an array holding those parameters.

See Varargs.

Hi,

If the identifier references an array then why to use varargs when we can actually pass an array?

Thanks,

Because with varargs you can skip creating the array. Compare:

System.out.printf("Hello, I am %s %s%n", new Object[] {"Rob", "Prime"});
 
System.out.printf("Hello, I am %s %s%n", "Rob", "Prime");

Now which do you prefer?

The compiler actually turns the second call into the first call so during runtime there is no difference, but your source code will be easier to read.
