如何开始通过从ArrayList中集索引迭代？ [英] How to start iterating through ArrayList from set index?

问题描述

我有一个的ArrayList 和我要开始通过它，比如说，从指数100到结束迭代。我该怎么做呢？

I have an ArrayList and I want to start iterating through it from, say, index 100 to the end. How do I do that?

推荐答案

有很多方法可以做到这一点。在这个例子我想你的列表可以保存整数。

There are many ways to do this. In this examples I assume your list holds Integers.

1. 您可以使用的ListIterator

1. You can use ListIterator

ListIterator<Integer> it = list.listIterator(100);
while (it.hasNext()) {
    System.out.println(it.next());
}

或为（内循环，以保持迭代范围）

or with for (to keep iterator scoped inside loop)

for (ListIterator<Integer> lit = list.listIterator(100); lit.hasNext();) {
    System.out.println(lit.next());
}

或正常的循环，但开始从 I = 100

for (int i=100; i<list.size(); i++){
    System.out.println(list.get(i));
}

或只是创建子列表，并遍历它就像你通常做

or just create subList and iterate over it like you normally do

for (Integer i : list.subList(100, list.size())){
    System.out.println(i);
}
