Apache Velocity --How to access data from ArrayList

[Ravi Kiran Va]

Hi

I am having a query in displaying data from the ArrayList using Apache Velocity Framework.

Here is a sample code :

I am setting data inside the ArrayList as shown .

ArrayList list = new ArrayList();
        list.add("TXNID001");
        list.add("89891898989889899");
        list.add("TXNID002");
        list.add(2,"89891898989889800");
        list.add("TXNID003");
        list.add(2,"89891898989889899");
context.put("list",list)

Now my requiremnt is that i need to display the TXNID and its related data as shown :

TXNID001 89891898989889899
TXNID002 89891898989889800
TXNID003 89891898989889899

I started this way , but please help me to complete the whole thing

#foreach( $name in $list )
   
// Need Logic Here .

#end

Please share your views .

Thanks in advance .

You have posted in the wrong forum, so I shall move your thread.

Why are you not parameterising the List?
Write down on paper what the 6 elements are in your List. Write how you intend to recover them and how to use the printf method to display them. Also check that you are entering them in the order you want.

Hi , Campbell thanks for the answer , actually the business logic is developed by someone else , and i am suppoused to display the contents of the ArrayList only as per the explained scenario .

So any ideas .

[Campbell Ritchie]

Write down the logic of how you intend to display those values. Are the TXN and 89 strings related or paired in any way in the List? How are you ordering them in the List? Should you be using a Map instead?

Thanks Campbell

They are added to the ArrayList as

while(rs.next())
{

list.add(rs.getString(1)); // This belongs to the Txn Ids
list.add(rs.getString(2));This belongs to the Txn data
}

Thank you .

But some of the entries are being added in the middle of the list for no apparent reason. It's bad enough that somebody decided to use a list to hold pairs of entries, but looking at that code I couldn't even predict what order the entries will end up in.
