I MUST BE STUPID

[Dave Van Even]

how comes this doesn't work ??
DrawStrategy.java

public interface DrawStrategy
{
public void draw(String str);
}

compiles fine
�
Base.java

class SimpleDrawStrategy implements DrawStrategy
{
public void draw(String str)
{
System.out.println(str);
}

}
class QuotedDrawStrategy implements DrawStrategy
{
public void draw(String str)
{
System.out.println("\"" + str + "\"");
}
}

public class Base {
private static void draw(String str, DrawStrategy ds)
{
ds.draw(str);
}

public static void main(String[] args)
{
String string = "Dit is strategy";

draw(string, new SimpleDrawStrategy());
draw(string, new QuotedDrawStrategy());
}
}

produces an error on compile: cannot resolve symbol DrawStrategy
(files are in the same directory)
I MUST BE STUPID not to see my mistake

Being in the same directory is to my opinion not enough. Do they belong to the same package?

[Dave Van Even]

If I put them in the same package, I get the same result

Do you use an IDE or do it "by hand"?
Where is the .class file generated? Check that if you compile them separetely, the directory where your outputs are generated has to be in your classpath.

It compiles and runs fine for me, output is -
Dit is strategy
"Dit is strategy"
I have just put all classes in one folder, no package.
I put them in seperate files, so i have 4 java files and 4 class files.

[Dave Van Even]

I forgot to put . in my classpath
thanks for helping out!

Dave, Dave, Dave,
You KNOW that there is no such thing as a STUPID question (Cindy slowly shakes head). We have ALL overlooked little things that hang us up.
I personally take objection to you calling someone stupid that is smart enough to figure out his own mistake - and I think that you owe him an apology .

[Margaret Tan]

YEAH to Cindy!!! Gosh, plenty of nice people here in JavaRanch huh?

[David O'Meara]

and I'd finish up with "Hands up anyone who hasn't made this mistake"

Dave.
