Inheriting the main method
- by Eric
I want to define a base class that defines a main method that instantiates the class, and runs a method. There are a couple of problems though. Here is the base class:
public abstract class Strategy
{
abstract void execute(SoccerRobot robot);
public static void main(String args)
{
Strategy s = new /*Not sure what to put here*/();
s.execute(new SoccerRobot())
}
}
And here is an example derived class:
public class UselessStrategy
{
void execute(SoccerRobot robot)
{
System.out.println("I'm useless")
}
}
It defines a simple execute method, which should be called in a main method upon usage as a the main application. However, in order to do so, I need to instantiate the derived class from within the base class's main method. Which doesn't seem to be possible.
I'd rather not have to repeat the main method for every derived class, as it feels somewhat unnessary.
Is there a right way of doing this?
