1,Although the condition "value.indexOf("(") < 0"  can be instead by "bracketsCount(value,'(') < bracketsCount(value,')')",use "||",cos the sencond condition can rarely be satisfied and the second condition call a mehtod including a for loop which will lower the performance.

2,no if in if.

//before refactoring

    if (value.endsWith(")"))
      {
       //AR43966, modify by Jerry Gao,April 24,2007
       if(value.indexOf("(") < 0 || bracketsCount(value,'(') < bracketsCount(value,')')){
        value = value.substring(0, value.length() - 1);
        rightBrackets[i] = "yes";
       }
       //end
      }

//after refactoring

 

 

  //AR43966, modify by Jerry Gao,April 25,2007
            //add condition after &&
            if (value.endsWith(")") && (value.indexOf("(") < 0 || bracketsCount(value,'(') < bracketsCount(value,')'))) {
                value = value.substring(0, value.length() - 1);
                rightBrackets[i] = "yes";
            }


    /**
     * get the count of destination char,add by Jerry Gao for AR43966,April 25,2007
     * @param sourceStr - source string
     * @param desChar - the char which want to search
     * @return the count of destination chars
     */
    private static int bracketsCount(String sourceStr,char desChar){
     int count = 0;
     for(int i = 0; i < sourceStr.length();i++){
      if(sourceStr.charAt(i) == desChar)
       count++;
     }
     return count;
    }
