java - 如何使用 Java 中的模式匹配器类从给定的字符串中查找匹配的两个或多个单词？

Question

我使用下面的代码来匹配给定字符串中的两个单词，但它不起作用。

String inputText = "I want to know relating to cloud based erp services.";
Set<String> words = new HashSet<String>();
words.add("erp");
words.add("cloud");

Pattern p = Pattern.compile("erp|cloud");

Matcher m = p.matcher(inputText);
if (m.find())
{
    return m.group();
    System.out.println("Yes we providing it.");
}

Answer 1

将您的代码修改为:

  Pattern p = Pattern.compile("erp|cloud");

    Matcher m = p.matcher(inputText);
    String match = "";
    if (m.find())
    {
        match =  m.group();
        System.out.println("Yes we providing it.");
    }
    return match;
