here is the problem
I have an Object[] args[];

I want use this array args to transfer the values.
For example args[0] is a int; args[1] is a string.

The problem is I can't change a int to string, I use this way

int refer=1
args[0]= (Object) refer;

but it doesn't work

HELP

Thanks a lot
fAnS.

You can't cast an int to an Object. Do this instead:

args[0] = new Integer(refer);

Uh-huh. The primitives are not objects, so they don't inherit from
Object thus you can't do that cast. Use primitive's wrappers.

Or, in 1.5, simply

args[0] = i; // will generate the same code as args[0] =
Integer.valueOf(refer);
