如何在存储在列表中的多个分隔符上拆分字符串？

Question

我有一个分隔符列表，例如

List<String> delimiters= Arrays.asList(",",".");

如果我有一个像"ab,c"这样的字符串。

如何拆分所有分隔符？

Answer 1

你可以做一个正则表达式。

@Test
public void test() {
    List<String> delimiters = Arrays.asList(",", ".", "?");
    String str = "a.b,c?dr";

    StringBuilder regex = new StringBuilder();
    regex.append("[");
    delimiters.stream().forEach(delimiter -> regex.append(delimiter + "/"));
    regex.append("]");

    String[] result = str.split(regex.toString());
}

Answer 2

请检查以下代码是否可以解决您的问题：

List<String> delimiters = Arrays.asList(",", ".", "?", ":");

for (String delimiter : delimiters) {
  text = text.replace(delimiter, " "); //replace all delimiter occurrence with space
}

String[] output = text.split(" "); //split using space

Answer 3

    String s = "a.b,c";
    String[] split = s.split("[.|,]");

这个怎么样？ 使用“|” 分隔多个分隔符，记得加[]，否则需要转义

Answer 4

这是代码：

import java.util.Arrays;
import java.util.List;

public class StringSplitMultipleDelimeter {

    public static void main(String[] args) {
        List<String> delimiters= Arrays.asList(",",".","!","?","$","&","^","%","@");
        String givenString = "Test,String.with?Multiple@delimeters!example";
        //Create Regex to split sting
        StringBuilder regex = new StringBuilder();
        regex.append("[");
        delimiters.forEach(delimeter -> regex.append(delimeter));
        regex.append("]");
        String[] tokens = givenString.split(regex.toString());
        System.out.println("Number of tokens = " + tokens.length);
        for(int i =0; i<tokens.length; i++) {
            System.out.println(tokens[i]);
        }
    }
}

Answer 5

您可以先在字符串上使用 replaceAll 并将其全部转换为固定分隔符（您的选择），就像这样 - 然后您可以根据它拆分它：

String[] newArray = stringArray.replaceAll("[\\.]", ",").split(",");
