请问：在JSP中怎么把字符串转换为DOUBLE和INT型？？？急急！！！！！

[xiaolei_418]

double money = (double)ruquest.getParameter("money");
double int = (int)ruquest.getParameter("kindinfo");
我这样写为什么不对？该怎么写？？？急急！！！

[javastart]

Double.valueOf(parm)

[liad]

double money = new Double(ruquest.getParameter("money")).doubleValue();

[xiaolei_418]

不好意思，帖子有错：
Int kindinfo = (int)ruquest.getParameter("kindinfo");

[juhwali]

String money = (double)ruquest.getParameter("money");
String info = (int)ruquest.getParameter("kindinfo");
double d = 0;
int i = 0;
try{
d = Double.parseDouble(money);
i = Integer.parseInt(info);
}catch(Exception e){
}

[juhwali]

String money = (double)ruquest.getParameter("money");
String info = (int)ruquest.getParameter("kindinfo");
double d = 0;
int i = 0;
try{
d = Double.parseDouble(money);
i = Integer.parseInt(info);
}catch(Exception e){
}

[defan]

String aa=ruquest.getParameter("kindinfo");
int kindinfo=Integer.parseInt(aa);

String转换成int
1). int i = Integer.parseInt([String]); 或
i = Integer.parseInt([String],[int radix]);

2). int i = Integer.valueOf(my_str).intValue();

String转换成Double
1). double i = Double.parseDouble([String]); 或
i = Double.parseInt([String],[double radix]);

2). double i = Double.valueOf(my_str).intDouble();

严重同意楼上的

[elathen]
