java实现CSV 字段分割

 private static String[] cvsField(String line){ List fields = new LinkedList<>(); char[] alpah = line.toCharArray(); boolean isFieldStart = true; int pos = 0; int len = 0; boolean yinhao = false; for(char c : alpah){ if(isFieldStart){ len = 0; isFieldStart = false; } if(c == '\"'){ yinhao = !yinhao; } if(c == ',' && !yinhao){ fields.add(new String(alpah, pos - len, len)); isFieldStart = true; } pos++; len++; } return fields.toArray(new String[0]); }
