public static String showInputDialog(Component, Object, Object);
public static String showInputDialog(Component, Object, String, int);

Every one of these returns a string.

The final one:

Code:

public static Object showInputDialog(Component, Object, String, int, Icon, Object[], Object);

Returns an object. It's used for selections though, not direct input.
