type saftey and static reference errors

[nomad]

Hello Everyone...
I have rewrite my code and I ran into some problems.
I have two problems.

1. What does this mean "Type safety: The method add(Object) belongs to the raw type ArrayList. References to generic type ArrayList<E> should be parameterized" at this statement

arlist.add(temp);

2. how do I change this "Cannot make a static reference to the non-static field empid"

 for(String idx :  empid

)


Thanks

here is my code

In the future please adhere to the proper naming of new thread questions.

See Use a Good Thread Title

In your first question you must have an object type between brackets so that the data structure knows what object it is allowed to operate on.

Your other question has something to do with the way that you are calling the method. Either it needs to be called statically in which you put the ClassName.MethodName(arguments) or you must create an object of ClassName and then call methods using the object (ie classObject.MethodName(arguments))

I sudden realized that I can make problem 2 static.
Will have to rethink this...

thanks
