How can I cast a list using generics in Java?

Question

Please consider the following snippet:

public interface MyInterface {

    public int getId();
}

public class MyPojo implements MyInterface {

    private int i         


        

Answer 1

You should be doing:

public ArrayList getMyInterfaces() {   
   ArrayList myPojos = new ArrayList(0);    
   myPojos.add(new MyPojo(0));    
   myPojos.add(new MyPojo(1));    
   return myPojos;
}
