for (int i = 0; i <= max+1; i++) { list.add(i,0); } int c=0; for (Interval l : airplanes) { int start = l.start; int end = l.end; c++; System.out.println("第"+c+"次遍歷開始"); System.out.println("init data in ("+start+" , "+end+")"); for (int i = start; i < end; i++) { list.add(i, list.get(i)+1); System.out.println("end ("+i+" <=> "+list.get(i)+")"); } } return Collections.max(list);Interval的構(gòu)造器 是public Interval(int start, int end) { this.start = start; this.end = end; }為什么，index為５（６也有這樣的問題）的list在第三次遍歷的時候被初始化為２，在第４次遍歷的時候，不應(yīng)該被增加到３的麼？

Class AbstractList<E>中 add 方法的文檔:
public void add(int index,E element)
Inserts the specified element at the specified position in this list. Shifts the element currently at
that position (if any) and any subsequent elements to the right (adds one to their indices).
