EnumMap constructor not found

Given that I have the requisite

import java.awt.Color;
import java.util.EnumMap;

and

enum Terrain { ... }

then as far as I can tell from the documentation, this should work

static EnumMap<Terrain, Color> colors = new EnumMap<Terrain, Color>(Terrain.class);

but it actually gives me this error

cannot find symbol
symbol  : constructor EnumMap()
location: class java.util.EnumMap<Terrain,java.awt.Color>
static EnumMap<Terrain,Color>colors=new EnumMap<Terrain, Color>();

What am I missing?

Solution

  • The code the compiler is quoting doesn't match what you've claimed to have. It looks like you're not actually providing an argument to the constructor. This works fine, for example:

    import java.util.EnumMap;

enum Foo {}

public class Test {    
    public static void main(String[] args) {
        EnumMap<Foo, String> map = new EnumMap<Foo, String>(Foo.class);
    }
}
