ClassCast Exception

[maya.more]

I get class cast exception when explicitly casting Double to Int

This is my code
List<Integer> NumList




for (Object Num: NumList){

if (Num instanceof Integer){

pList.add((Integer) Num);

} else {

Double doubleNum = (Double) Num;
Integer integerNum = Num.intValue(); (Exception occurs here)
pList.add(integerNum);

}
}


This works fine in Windows , but causes class cast exception when deployed in Linux Root Cause: java.lang.Double cannot be cast to java.lang.Intege


Any help is appreciated

Thanks

small change in code

for (Object Num: NumList){

if (Num instanceof Integer){

pList.add((Integer) Num);

} else {

Double doubleNum = (Double) Num;
Integer integerNum = doubleNum .intValue(); (Exception occurs here)
pList.add(integerNum);

}
}

Any ideas please?
Thanks

What is the full text of the error message?

The line with the comment does not do a cast. The cast is on the preceding line.

This is the stack trace

java.lang.Double cannot be cast to java.lang.Integer

That says what the problem is.
Try finding the correct type by using instanceof before casting.

When I debug and see the varialbles ,its of type Double

If its Double, then there should not be any problem casting it to Double.
