Question

I have an integer value in my java servlet code which is being retrieved from the database and i need to add that value to a cookie.

int k=rs.getInt(3);
Cookie c1= new Cookie("access", k);

But this line throws an error saying:

Cookie c1= new Cookie("access", k);
             ^
required: String,String
found: String,int
reason: actual argument int cannot be converted to String by method invocation
conversion
1 error

I understand the error but how do I go about passing a int value to a cookie. I am new to servlets. Your help would be most appreciated.

Answer 1

If you see the documentation of Cookie, the only constructor it has takes both the argument as String. So, you need to convert your integer value to a String.

You can use String.valueOf(int) method for that: –

int k=rs.getInt(3);
Cookie c1 = new Cookie("access", String.valueOf(k));
