Hi this is a save function for my program, this is the first time using "file dialog function" it is throwing an error I am not sure how to fix it.
The constructor FileDialog(Frame, String, int) is ambiguous
import java.awt.FileDialog;
public class save {
private void initialize() {
FileDialog fileOutputDialog =
new FileDialog(null, "Output File", FileDialog.SAVE);
}
}
FileDialog has two constructors of interest for this problem:
public FileDialog(Frame parent, String title, int mode)
public FileDialog(Dialog parent, String title, int mode)
If you call your constructor with a null first argument, how does the compiler know which constructor you want to call?
A better way to handle this would be to declare a variable of the right type, set it to null, and use that as the first argument instead. The static type of that variable allows the compiler to figure out which constructor you want.
For example, if you want the Frame constructor:
Frame unusedFrame = null;
FileDialog fileOutputDialog = new FileDialog(unusedFrame, "Output File", FileDialog.SAVE);
try this
FileDialog fileOutputDialog = new FileDialog(new Frame(), "Save file", FileDialog.SAVE);
instead of
FileDialog fileOutputDialog = new FileDialog(null, "Output File", FileDialog.SAVE);
