根据字符串定界符从字符串中获取子字符串列表

Question

String s = "I like an orange as well as apple but mostly apple. apple, orange are the best fruits.";

String[] delimiter = {"orange", "apple"};

我想像下面这样拆分这个字符串：

{"I like an ", "orange", " as well as ", "apple", " but mostly ", "apple", ".", "apple", ",", "orange", " are the best fruits."}

上面我根据水果orange和apple拆分了字符串，但是这两个水果也是子字符串列表的一部分。

使用this answer:

public class Solution {
    public static String[] getTokens(String str, String[] delimeters) {
        if (delimeters.length == 0) {
            return new String[]{str};
        }
        // Create regex: ((?<=delimeter)|(?=delimeter))
        String delimetersConcatenatedWithOr = "(" + String.join(")|(", delimeters) + ")";
        String regex = "((?<=" + delimetersConcatenatedWithOr + ")|(?=" + delimetersConcatenatedWithOr + "))";
        // Split using regex
        return str.split(regex);
    }
    public static void main(String args[]) {
        String str = "I like an orange as well as apple but mostly apple. apple, orange are the best fruits.";
        String[] delimeters = {"apple", "orange"};
        for (String token : getTokens(str, delimeters)) {
            System.out.println("{" + token + "}");
        }
    }
}
