Java正则表达式

import java.util.regex.Pattern;
public class RegularExpression {
 /**

   for(String token:tokens){
    System.out.print(token+"\t|");
   }
   System.out.println();
  }
 * 显示结果:
 * justin |64/5/26 |09323432434 |4546465 |
   momor |68/7/23 |43543653     |34535435 |

  for(String token:tokens){
   System.out.print(token+" ");
  }
  
  System.out.println();
  
  
   * 返回结果是:
   *  d ad
            ebcadxbc
            解释:使用.bc来作比对,由于符合的子字符串有abc ebc xbc 3个,所以split()方法会使用这三个字符串来做字符串分离
            ,返回的就是不符合表达式.bc的d和ad了,同理..cd
