程序中正则的使用

public static boolean matchPattern(String source, String pattern)
 {
  RE patt = getPatternObj(pattern);
  if (patt.match(source)) {
   return true;
  }
  else {
   return false;
  }
 }
 /**
 * 获取匹配模式对象
 */
 public static RE getPatternObj(String pattern)
 {
  RE patt = null;
  try {
   patt = new RE(pattern);
   patt.setMatchFlags(RE.MATCH_SINGLELINE | RE.MATCH_CASEINDEPENDENT);
  }
  catch (Exception e) {
   e.printStackTrace();
  }

  return patt;
 }
