string a=“this is a string”;int b = a;就会报类似的错误了。常见于函数调用中参数的顺序不对，或者缺了部分参数时。
public static int powers(double x, int n) { int result = Math.pow(x, n); //ERROR***// //[I]Type mismatch:cannot convert from double to int[/I]// result = x * powers(x, n-1);//ERROR***// //[I]Type mismatch:cannot convert from double to int[/I]// System.out.println...
您好，我来为您解答：一般是UserID为String的情况，如果你的UserID是Integer int l_UserID=((Integer)session.getAttribute("UserID")).intValue();如果我的回答没能帮助您，请继续追问。

int type = (Integer) scan_device.get(position).get(device_mapid[4]);int是基本类型 怎么能从Object类型强转呢
if(cid ==(int)cidActiveList.get(i)) 又出现如下错误提示: Cannot cast from Object to intDataConnectionTracker.java/check/frameworks/base/telephony/java/com/android/internal/telephonyline 657Java Problem 最后在网上找了一翻,最终改为如下, 即问题解决。

The call is ambiguous between the following methods or properties: 'System.Math.Round(double)' and 'System.Math.Round(decimal)' Cannot implicitly convert type 'double' to 'int'. An explicit conversion exists (are you missing a cast?)
