java - cannot find symbol -method getvalue (); maybe you meant : intValue -

import java.util.arraylist; public class averager {     private arraylist list;     public averager() {       list = new arraylist();    }     public void addgrades(int test, int quiz) {       list.add(new integer(test));       list.add(new integer(test));       list.add(new integer(quiz));    }     public double getaverage() {       int sum = 0;       for(int = 0; < list.size(); i++) {          sum += ((integer)list.get(i)).getvalue();       }       return sum / list.size();    } } 

integer class not have getvalue() method. there intvalue() method. arithmetic operations don't have call - java autoboxing:

sum += (integer)list.get(i);
