想获取字符串内getcolsum(xxx)的字符串，正则表达式该怎么写？

Question

java 自己写了一个正则怎么都验证不到getcol 开头后面跟 3个任意字符，（xx）这样的字符

    String str = "798>getcolsum(fmoney)>getcolavg(fmoney)";
    String pattern = "getcol[\\w]{3}\\([\\w.]*\\)";

    Pattern r = Pattern.compile(pattern);
    Matcher m = r.matcher(str);
    System.out.println(m.matches());

这个表达式应该怎么写？

Answer 1

 String str = "798>getcolsum(fmoney)>getcolavg(fmoney)";
            String pattern = "getcol\\w{3}\\([\\w.]*\\)";
            Matcher m  = Pattern.compile(pattern).matcher(str);
            List<String> result=new ArrayList<String>();
            while(m.find()){
                result.add(m.group());
            }
