例子 (Example)

以下示例显示了java.time.Matcher.pattern（）方法的用法。

package cn.xnip;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class MatcherDemo {
   private static final String REGEX = "foo";
   private static final String INPUT = "fooooooooooooooooo";
   private static Pattern pattern;
   private static Matcher matcher;
   public static void main( String args[] ) {
      pattern = Pattern.compile(REGEX);
      matcher = pattern.matcher(INPUT);
      System.out.println("Current REGEX is: "+REGEX);
      System.out.println("Current INPUT is: "+INPUT);
      System.out.println("pattern(): "+matcher.pattern());
      System.out.println("matches(): "+matcher.matches());
   }
}

让我们编译并运行上面的程序，这将产生以下结果 -

Current REGEX is: foo
Current INPUT is: fooooooooooooooooo
pattern(): foo
matches(): false
