Re: LinkedList newbie

Hi,

Please correct me if I am off the beaten path. I am new to java and I
am trying to use LinkedLists.
I created a class Transaction as my data storage object. I have a class
checkBook that attempts to write create a linkedlist of transactions.
Attached are the 2 files:
public class Transaction
{
    Transaction()
    {
        transType="";
        accntTotal=0;
    }

    public void setTransType(String newTransType)
    {
        transType = newTransType;
    }

    public String getTransType()
    {
        return transType;
    }

    private String transType;
    private double accntTotal;
}

import java.util.*;
public class chequeBook
{
    public void chequeBookList()
    {
        LinkedList tranList = new LinkedList();
// ArrayList tranList = new ArrayList();
        Transaction financialTrans = new Transaction();
        financialTrans.setTransType("Deposit");

        tranList.add(financialTrans);
// System.out.println(tranList.peek().getTransType()+ " from peek");
    }

    public static void main (String args[])
    {
        chequeBook chkbook = new chequeBook();

        System.out.println("In main method.");
    }
}

When attempting to run this little test proggie I get the following:
chequeBook.java:12: warning: [unchecked] unchecked call to add(E) as a
member of
 the raw type java.util.LinkedList
                tranList.add(financialTrans);

I am totally lost and would greatly appreciate if someone could point
out and explain the warning message.

Thanks in advance...
