我正在尝试创建正则表达式 匹配一个字符串,该字符串不包含某些特定单词并跟随某个单词,如下所示:
(?<!(state|government|head).*)of
例如:
state of -> not match
government of -> not match
Abc of -> match
但它不起作用。我不知道为什么,请帮我解释一下。
答案 0 :(得分:0)
您可以将此正则表达式与否定前瞻一起使用。样本如:
public static void main(String[] args) {
Pattern pattern = Pattern.compile("^(?!state|government|head).*$");
String s = "state of";
Matcher matcher = pattern.matcher(s);
boolean bl = matcher.find();
System.out.println(bl);
s = "government of";
matcher = pattern.matcher(s);
bl = matcher.find();
System.out.println(bl);
s = "Abc of";
matcher = pattern.matcher(s);
bl = matcher.find();
System.out.println(bl);
}
希望这有帮助!
