public Pattern pattern()

返回值

創建此匹配器的模式。

示例

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

package com.zaixian;

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());
   }
}

編譯並運行上面的程式，這將產生以下結果 -

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