I'm writing a Java class that's implementing an interface called Command, which contains the methods isValid() and run(), as follows:
public class DailyEnergy implements Command {
@Override
public boolean isValid(String command) {
return false;
}
@Override
public void run(String command) throws Exception {
}
}
and here's the Command.java file:
public interface Command {
public boolean isValid(String command);
public void run(String command) throws Exception;
}
Within this class, I'm implementing the superclass methods isValid() and run(), and I want to add the @Override annotation, but Eclipse gives an error saying that "the methods must override superclass methods".
Even when I take out the methods and import them automatically with Eclipse, if I add the annotation, I get the error. If anyone can shed some light as to why I can't use the @Override annotation, that would be greatly appreciated.
