List的遍历条件删除
List的遍历条件删除
List<Integer> l = new ArrayList<Integer>();for (int i = 0; i < 10; i++) {l.add(i);}// 方法1，目标是删除1for (int i = 0; i < l.size(); i++) {if (l.get(i) == 1) {l.remove(i);}}System.out.println(l);// 方法2，目标是删除2Iterator<Integer> it = l.iterator();while (it.hasNext()) {if (it.next() == 2) {it.remove();}}System.out.println(l);// 方法3，目标是删除3(错误)for (Integer i : l) {if (i == 3) {l.remove(i);}}System.out.println(l);
