我有128筆從資料庫讀出,想用StringTokenizer的方法把那128筆資料轉成浮點數放入陣列,但不知道為什麼轉換後陣列裡面都是0,剛剛在學如何使用,麻煩有經驗的人指點,謝謝
[code] while(rs5.next())
{
String A=rs5.getString(1);
StringTokenizer st1=new StringTokenizer(A);
float [] st11=new float[128];
int iiii=0;
while(st1.hasMoreTokens())
{
// System.out.println(st1.countTokens());
st11[iiii++]=(float)Float.parseFloat(st1.nextToken());
//System.out.println(st1.nextToken());
System.out.println(st11[iiii+]);
}
}[/code]
