Question

I’m making a small (for fun) game where virtual robots fight each other. I have an array of names of the classes of these robots, but I don’t know how to load them. It’s probably clearer in codes:

String[] classes={"Bot1","Bot2","Bot123"};
Object[] bots=new Object[classes.length];

for(int i=0;i<classes.length;i++){
  bots[i]=UnknownFunction(classes[i]);
}

Additional details:

package Arena;

public class Bot {
    public void main(String args[]){

    }

    public void init(){
        System.out.print("Loaded");
    }
}

In the main file:

bot=Class.forName("Arena.Bot").newInstance();
bot.init();

Answer 1

You need Class.forName() method to load your class, and then newInstance() method to instantiate them. Assuming that you have a 0-arg constructor in them: –

bots[i] = Class.forName(classes[i]).newInstance();

Also note that, those class names has to be fully qualified names.
