The parsing method of the Java irregular string separated by commas (the field also contains commas)

/*** Java string comma split parsing method * This is specifically designed for cases where there are commas in double quotes or a field with a single quote * For example, string sss= "101,\" A\ "," China, Jiangsu \ "," b\ "," China,     BEIJING \ ", 1,0,\" c\ "" separated by commas to parse; * The correct split result is (101) (a) (China, Jiangsu) (b) (China, Beijing) (1) (0) (c) * If you use the Java split method, when you encounter (China, Beijing) These field values will be more divided a field out, is not correct, at the same time, the above 101, 1,0 without a double quote * We expect the ideal string to be a string of field values with double quotes, but we feel very annoyed when it happens. * Above is the original intention of this method design, in fact, this method is mentioned in the data structure of the university textbook, in this Java implementation of a bit , but the efficiency of the method execution I haven't tested yet * if anyone has a better way welcome to join the discussion O (∩_∩) o~ *@authorHsuchan *@version2014-11-30 22:30 *@paramSSS *@returnString []*/     Publicstring [] Commadivider (String sss) {//Double quote start tag        intQutationstart =0; //Double quote closing tag        intQutationend =0; Char[] Charstr =Sss.tochararray (); //used to stitch characters as a field valueStringBuffer SBF =NewStringBuffer (); //Results Listlist<string> list =NewArraylist<string>(); //CHAR-per- character processing         for(inti=0;i<charstr.length;i++) {            //no double quotes have been encountered before and the current character is \ "            if(Qutationstart = = 0&&charstr[i] = = ' \ ' ') {Qutationstart= 1; Qutationend= 0; Continue; } Else if(Qutationstart = = 1&&charstr[i] = = ' \ ') {//preceded by a double quotation mark and the current character is \ "Description field stitching that's overQutationstart= 0; Qutationend= 1; //when the last character is double quotation marks, because the next loop will not be executed, save it here                if(i = = Charstr.length-1&&sbf.length ()! = 0) {List.add (sbf.tostring ()); Sbf.setlength (0); }                Continue; } Else if(Qutationstart = = 1&&charstr[i] = = ', ' &&qutationend = = 0) {//handling \ "China, Beijing \" This nonstandard stringsbf.append (Charstr[i]); Continue; } Else if(Charstr[i] = = ', ') {//The field ends and the stitched field values are stored in the listList.add (sbf.tostring ()); Sbf.setlength (0); Continue; }            //do not belong to the delimiter on the splicingsbf.append (Charstr[i]); if(i = = Charstr.length-1&&sbf.length ()!=0) {List.add (sbf.tostring ()); Sbf.setlength (0); }                    }                return(string[]) List.toarray (Newstring[list.size ()]); }
