请问一个 Java String 的有关问题.

    public void Handle() {        try {            FileReader fs = new FileReader("adult.txt");            BufferedReader br = new BufferedReader(fs);            FileWriter fw = new FileWriter("out.txt");            BufferedWriter bw = new BufferedWriter(fw);            String strLine = null;            String[] temp;            strLine = br.readLine();            int m = 0;            boolean test=false;            String strTemp = null;                        while (strLine != null) {                temp = strLine.split(",");          [color=#FF0000]//将文件adult.txt中的每一行以逗号分隔开, 返回字符串数组temp,[/color]                String[] temp1 = new String[8];     [color=#FF0000] //用于取temp字符串数组中特定的字段..[/color]                                temp1[0] =temp[0].substring(0, temp[0].length());                temp1[1] =temp[1].substring(0, temp[1].length());                temp1[2] =temp[3].substring(0, temp[3].length());                temp1[3] =temp[5].substring(0, temp[5].length());                temp1[4] =temp[6].substring(0, temp[6].length());                temp1[5] =temp[8].substring(0, temp[8].length());                temp1[6] =temp[9].substring(0, temp[9].length());                temp1[7] =temp[13].substring(0, temp[13].length());                                for(int i=0;i<8;i++)                    if(temp1[i].equals("?"))
