Read and write values fo collection

[Former Member]

Hi Experts ,

Pls guide me in resolving the below issue

1. I have a collection XX with 5 columns (Q1 , Q2,Q3,Q4,Q5) .

On a particular condition , I'm trying to add new rows .

consider I have added 2 rows .

//valu=2

for(int j =0;j<valu;j++){

annual.add( newMember );

}

}

On adding 2 rows , I'm trying to read first row and trying to set value for Q1

savingsIter = annual.iterator();

while (savingsIter.hasNext())

{

member = savingsIter.next();

firstRow=annual.get(0);

firstRow.set("ERS_Q1", Qu1);

}

On trying this , automatically Q1 of 2nd row is auto-populated with value updated in 1st row

Pls suggest me where i'm going wrong

THANKS IN AdVANCE

From what you have mentioned above, it looks like You have created one collection object and have added the same collection object n number of times. Hence any change made in one of the objects is reflected in all the objects.

Place the code to create the collection object and the code to add the collection object(which u have already done) inside the looping construct(in ur case the for loop). This will solve ur problem.

Hope this helps.

retrieve the collection. Use a normal for loop and and skip the first 2 rows.

say colln is the collection

size=colln.size();

for(i=2;i<size;i++){

collnBean=colln.get(i);

//perform the required operations on colln bean

}
