Trying to access subclass methods

Question

So i have an array called roster filled with both Pitchers and Batters and Players( the Player is the super-class of both pitchers and batters)

private Player[] roster;

roster[i] = new Pitcher();

How i would i access methods in the pitcher? For example:

 public double calculateTeamERA() { double ERA = 0; for(int i = 0; i < 25; i++) { if(roster[i] instanceof Pitcher) { ERA+= roster[i].calculateERA(); } } return ERA; } 

So i have a calculate method, and the method calculateERA() is correct syntax, i'm just wondering if there is a way to tell it to access the Pitcher object, because it gives me a syntax error there is no calculateERA() in the PLAYER method which there isn't it's in the pitcher method.

Answer 1

Actually found the answer! You have to type cast it and you have to obey the hierarchy so in my case it would be:

ERA+= ((Pitcher)roster[i]).calculateERA();
