java - 除了拆分之外，还有其他方法可以从字符串中获取列表吗？

Question

有一个字符串是一个分隔字符串:item_1|item_2|item_3，在这个例子中分隔符是|。

我的老板不喜欢split 方法来获取字符串的不同部分:他认为这样做有风险，但他不太确定风险是什么。那么还有其他方法可以从分离的字符串中获取 List 吗？

Answer 1

import java.util.ArrayList;
import java.util.List;

public class SplitUsingAnotherMethodBecauseBossLikesWastingEveryonesTime {

    public static void main(String[] args) {
        System.out.println(split("Why would anyone want to write their own String split function in Java?", ' '));
        System.out.println(split("The|Split|Method|Is|Way|More|Flexible||", '|'));
    }

    private static List<String> split(String input, char delimiter) {
        List<String> result = new ArrayList<>();
        int idx = 0;
        int next;

        do {
            next = input.indexOf(delimiter, idx);

            if (next > -1) {
                result.add(input.substring(idx, next));
                idx = next + 1;
            }
        } while(next > -1);

        result.add(input.substring(idx));

        return result;
    }
}

输出...

[Why, would, anyone, want, to, write, their, own, String, split, function, in, Java?]
[The, Split, Method, Is, Way, More, Flexible, , ]
