下列代码哪行存在编译错误？
import java.util.*;
public class Test {
public static void main(String[] args) {
List<String> name = new ArrayList<String>();
List<Integer> age = new ArrayList<Integer>();
List<Number> number = new ArrayList<Number>(); /* line:0 */
name.add("icon");
age.add(18);
number.add(314);
getUperNumber(name); /* line:1 */
getUperNumber(age); /* line:2 */
getUperNumber(number); /* line:3 */
}
public static void getUperNumber(List<? extends Number> data) {
System.out.println("data:" + data.get(0));
}
}
