把类似“我……我要……学学学学……编程java”通过正则表达式修改成“我要学编程java”

自己的实现

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

public class RegExp13 {

    public static void main(String[] args) {

        String content = "我我我要要要学学学学编程java!";

        String regStr = "(.)\\1+";

        Pattern pattern = Pattern.compile(regStr);

        Matcher matcher = pattern.matcher(content);

        while (matcher.find()) {

            String str = matcher.group(0);

            content = matcher.replaceFirst(str.charAt(0) + "");

            matcher = pattern.matcher(content);

            System.out.println("content：" + content);

        }

        System.out.println("content：" + content);
        
    }

}

content：我要要要学学学学编程java!
content：我要学学学学编程java!
