boolean matches() - 示例

下面的示例显示java.time.Matcher.matches()方法的用法。

package com.learnfk;

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("lookingAt(): "+matcher.lookingAt());
      System.out.println("matches(): "+matcher.matches());
   }
}

让无涯教程编译并运行以上程序，这将产生以下输出-

Current REGEX is: foo
Current INPUT is: fooooooooooooooooo
lookingAt(): true
matches(): false
