正则表达式匹配Java中的多行
Pattern.MULTILINE将有助于匹配Java中的多行。以下是显示此的示例-
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MultiRegex {
public static void main(String[] args) {
if (args.length<1) {
System.err.println("run the program from command line");
System.exit(1);
}
String regexString = args[0];
String spamString = "welcome to java world";
Pattern aPattern = Pattern.compile(regexString,Pattern.MULTILINE);
Matcher aMatcher = aPattern.matcher(spamString);
if (aMatcher.find()) {
System.out.println("got a match");
} else {
System.out.println("no match");
}
}
}
