java - I have created a date using SimpleDateFormat, how do I convert into a string?

newDate =(newDaysAdded+"/"+month+"/"+year);
            
SimpleDateFormat date = new SimpleDateFormat("dd/MM/yyyy");
try
            {
 Date newDateOne =
            date.parse(newDate);

When
I
try:

view.writeToScreen(newDateOne);

I
get the error:

 Incompatible
            types: Date cannot be converted to
            String.

Here
is the writeToScreen method:

void
            writeToScreen(String
            s);

However from there
I can't turn into a string, I have tried:
String test =
Date.toString(newDateOne);

Can anyone
help?
