Java实现正则匹配 “1234567” 这个字符串出现四次或四次以上

package com.s;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class RegexMatchExample {
    public static void main(String[] args) {
        String text = "4211234567 some text 1234567 some more text 1234567 another 1234567 more text 1234567";
        String patternString = "(?:1234567[^1234567]*){4,}";
        // Compile the pattern
        Pattern pattern = Pattern.compile(patternString);
        // Create matcher object
        Matcher matcher = pattern.matcher(text);
        if (matcher.find()) {
            System.out.println("The string '1234567' appears four times or more.");
        } else {
            System.out.println("The string '1234567' does not appear four times or more.");
        }
        // To count exact number of occurrences
        Pattern countPattern = Pattern.compile("1234567");
        Matcher countMatcher = countPattern.matcher(text);
        int count = 0;
        while (countMatcher.find()) {
            count++;
        }
        System.out.println("The string '1234567' appears " + count + " times.");
        if (count >= 4) {
            System.out.println("The string '1234567' appears four times or more.");
        } else {
            System.out.println("The string '1234567' does not appear four times or more.");
        }
    }
