i'm creating jtextfield this:

jtextfield item1 = new jtextfield(10); 

and here tried set text it:

string setvalue = item1.settext("text"); 

this doesn't work. why?

about edit: full code commented out, not deleted. --mightypork

settext() right choice, used in strange way.

string setvalue = item1.settext("text"); 

settext() has no return value, hence error void.
can't assign void variable.

try instead:

item1.settext("text"); 

or, if want value:

string setvalue = "text"; item1.settext(setvalue); 

or:

string setvalue; item1.settext(setvalue = "text");
