我好像缺了点什么I seem to be missing something
package zh.codegym.task.task07.task0707;
import java.util.ArrayList;
/*
那是什么类型的列表？
*/
public class Solution {
public static void main(String[] args) throws Exception {
ArrayList<String> list = new ArrayList<String>();
list.set(1, a);
list.set(2, b);
list.set(3, c);
list.set(4, d);
list.set(5, e);
int x = list.size();
System.out.println(x);
for (int i = 0; i < x; i++)
System.out.println(list.get(i));//在此编写你的代码
}
}
