In the following code, I get an error from the compiler on the last line that says: 'the type List is Ambiguous' (on the line that attempts to define cgxHist list). What am I doing wrong?
import java.awt.*;
import javax.swing.*;
import java.util.*;
public class drawr extends JPanel{
public static int animationSpeed=470;
public static int diameter = 50;
hBod allHBods[];
List<String> cgxHist = new ArrayList<String>();
I actually wanted the list to contain integers, but when I try to 'cast' the list as such, by replacing <String>
with <int>
, the error on that line becomes 'Syntax error on token "int", Dimensions expected after this token'. Advice please.
Both of these exist. You'll have to add the namespace in front to use one:
If you don't, it doesn't know how to interpret the
List<T>
: is it theawt
one orutil
? Ergo: ambiguous.The problem is that there is a
List
class in both thejava.awt
and thejava.util
package, and as you are importing all classes in those packages, the compiler doesn't know which one you mean.So you should either not use the asterisk to import all classes at the same time (just import the ones you actually need) or instead of
List
writejava.util.List<String> cgxHist = new ArrayList<String>();
