I tried to add an int variable to a vector:
{
int i = (int)tokenizer.nval;
Vector v = new Vector();
v.add(i);
}
Alas! The compiler error says "cannot resolve symbol", but similar String variable compiles well.

Who knows what the problem is.

Thanks.

If you look at the API, you'll see that the add method takes boolean add(Object o) an Object - so you cannot add primative data. You need to wrap the int in a suitable wrapper class like java.lang.Integer.

For more info on the java.lang.Integer object:

HI
The error is b'cos you are trying to add a primitive type to a vector where as the add(Object o) takes an Object as argument so to add an int value to a vector u can do it this way

int i = (int)tokenizer.nval;
Vector v = new Vector();
v.add(new Integer(i));
