如何在 Java Regex 中匹配不包含某个单词的行
范例
import java.util.regex.Matcher; import java.util.regex.Pattern; public class NoRegTest { public static void main(String[] args) { String s="^fun"; Pattern pattern = Pattern.compile(s); Matcher matcher = pattern.matcher("Java is fun"); if(!matcher.find()) { System.out.println("not found"); } } }
输出
not found
