Java面试题：循环删除 List 中的元素

package com.example;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class Demo {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>(Arrays.asList("Tom", "Jack", "Steve"));
        System.out.println(list);
        // [Tom, Jack, Steve]
        // 删除元素操作
        System.out.println(list);
        // [Tom, Steve]
    }
}

int length = list.size();
// 下标范围 [0, length - 1]
for (int i = length - 1; i >= 0; i--) {
    System.out.println(i);
    if ("Jack".equals(list.get(i))) {
        list.remove(i);
    }
}

// 先查找，再删除
int index = list.indexOf("Jack");
if (index > -1) {
    list.remove(index);
}

// @since 1.8
list.removeIf(x -> "Jack".equals(x));

// @since 1.8
list = list.stream()
        .filter(x -> !"Jack".equals(x))
        .collect(Collectors.toList());
