java从字符串中删除字母数字单词

Question

我正试图从字符串中删除字母数字单词

 String[] sentenceArray= {"India123156 hel12lo 10000 cricket 21355 sport news 000Fifa"};
    for(String s: sentenceArray)
        {
            String finalResult = new String();
            String finalResult1 = new String();
            String str= s.toString();
            System.out.println("before regex : "+str);
            String regex = "(\\d?[,/%]?\\d|^[a-zA-Z0-9_]*)";
            finalResult1 = str.replaceAll(regex, " ");
            finalResult = finalResult1.trim().replaceAll(" +", " ");
            System.out.println("after regex : "+finalResult);
        }

Answer 1

public static void main(String[] args) {
    String s = "India123156 hel12lo 10000 cricket 21355 sport news 000Fifa";
    // String s = "cricket abc";
    // cricket sport news
    System.out.println(s.replaceAll("\\b\\w+?[0-9]+\\w+?\\b", "").trim());

}

O/p:

cricket  sport news
