如何正则表达式拆分以接受十进制数？

(\d+)(\.\d+)?

import re

pattern = r'(\d+)(\.\d+)?'
text = 'The numbers are 42 and 3.14'
matches = re.findall(pattern, text)

for match in matches:
    print(match)

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main {
    public static void main(String[] args) {
        String pattern = "(\\d+)(\\.\\d+)?";
        String text = "The numbers are 42 and 3.14";
        
        Pattern regex = Pattern.compile(pattern);
        Matcher matcher = regex.matcher(text);
        
        while (matcher.find()) {
            System.out.println(matcher.group());
        }
    }
}
