[英]Java split regex patten letters and numbers
I want to split this regexp pattern 2 numbers-3 numbers-5 numbers and letter
in two part. 我想将此正则表达式模式分为
2 numbers-3 numbers-5 numbers and letter
两个2 numbers-3 numbers-5 numbers and letter
。 Numbers and "-" one array and the letters in the second array. 数字和“-”一个数组,第二个数组中的字母。
I been trying to figure it out for a while. 我一直试图找出答案。 Hoping I can get some help.
希望我能得到一些帮助。
Here is an example 这是一个例子
"12-123-12345A" <----- the string
// I want to split it such that it can be ["12-123-12345","A"]
I tried this 我试过了
"\\d{2}-\\d{3}-\\d{5}"
// that only give me ["", "A"]
and this 和这个
"(?<=\\D)(?=\\d)|(?<=\\d)(?=\\D)"
// ["12", "-", "123", "-", "12345", "A"]
\\D
matches any non-digit character (including -
). \\D
匹配任何非数字字符(包括-
)。 You'd better to use [^-\\d]
instead to exclude -
. 您最好使用
[^-\\d]
来排除-
。
String s = "12-123-12345A";
String parts[] = s.split("(?<=\\d)(?=[^-\\d])");
System.out.println(parts[0]); // 12-123-12345
System.out.println(parts[1]); // A

尝试这个
String[] a = "12-123-12345A".split("(?<=\\d)(?=\\p{Alpha})");
(\\d{2}-\\d{3}-\\d{5})(\\w) (\\ d {2} - \\ d {3} - \\ d {5})(\\ w)的

Here's the java code. 这是Java代码。 note double slash in replace of slash \\ --> \\\\
注意用双斜杠代替斜杠\\-> \\\\
package com.company;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main {
public static void main(String[] args) {
Pattern regex = Pattern.compile("(\\d{2}-\\d{3}-\\d{5})(\\w)");
Matcher matcher = regex.matcher("12-123-12345A");
matcher.find();
System.out.println(matcher.group(1));
System.out.println(matcher.group(2));
