Modify the body of the toString method so that it uses the for-each iterator idiom instead.

How do I fix this code?

import java.util.ArrayList; import java.util.Iterator; import java.util.List;

/** * IteratorError.java * Illustrates a common error when using Iterators. */ public class IteratorError {

/** * Identify and eliminate the errors regarding the use * of the iterator itr in the following method. */ public static int search(List list, T target) { int i = 0; Iterator itr = list.iterator(); while ((itr.hasNext()) && (!itr.next().equals(target))) { i++; itr.next(); } if (itr.hasNext()) { return i; } else { return -1; } }

/** Drives execution. */ public static void main(String[] args) { List ilist = new ArrayList(); ilist.add(2); ilist.add(4); ilist.add(6); ilist.add(8); ilist.add(10);

int loc = IteratorError.search(ilist, 8); System.out.println(loc); loc = IteratorError.search(ilist, 5); System.out.println(loc); }

}
