以下のソース(書ききれない為クラス、エラー等端折ってます・・・)を拡張for文、Generics の表記をせずに（５．０以前？の書き方に）書き直したいんですがどうすればいいですか？教えて下さい！
BufferedReader br = new BufferedReader(new FileReader(f));
String line;
line = br.readLine();
String[] headitems = line.split(",");
headsize = headitems.length;
articles = new ArrayList<String>();
for (int i = 1; i < headsize; i++) {
articles.add(headitems[i]);
}
while ((line = br.readLine()) != null) {
String[] items = line.split(",");
}
Result r = new Result(articles, items);// 1行の結果
for (String art : articles) {// 科目毎の合計
Integer val = totals.get(art);
if (val == null) {
val = 0;
}
totals.put(art, val + r.getResult().get(art));
}
total += r.getTotal();// トータル合計
results.add(r);
}
br.close();
Collections.sort(results);// 全部読んだ後ソート
}
public void writedown(File f) {
BufferedWriter bw = new BufferedWriter(new FileWriter(f));
// フォーマットして書き出し
bw.write(format());
bw.close();
}
private String format() {
StringBuffer buf = new StringBuffer();
buf.append("順位\t名前\t");
for (String art : articles) {
buf.append(art).append("\t");
}
buf.append("合計\n");
int rank = 1;
for (Result res : results) {
buf.append(rank).append("\t");
buf.append(res.getName()).append("\t");
for (String art : articles) {
buf.append(res.getResult().get(art)).append("\t");
}
buf.append(res.getTotal()).append("\n");
rank++;
}
buf.append("\t\t");//総計
for (String art : articles) {
buf.append(totals.get(art)).append("\t");
}
buf.append(total).append("\n");
return buf.toString();
}
public void reset() {/*集計に使う入れ物を洗う*/
headsize = 0;
articles = new ArrayList<String>();
results = new ArrayList<Result>();
totals = new HashMap<String, Integer>();
total = 0;
}
private int headsize;
private List<String> articles;
private List<Result> results;
private Map<String, Integer> totals;
private Integer total;
}
