Hi Ananad,
Please see correct code:


////////////////
private void insertLedgerBalance(int iRow)
{
try{
if (optReceipts.isSelected())
{
String atCode = (String)tbl_PettyReceipt.getValueAt(iRow, 0);
String atAmount = (String)tbl_PettyReceipt.getValueAt(iRow, 3);
}

else if(optDeduction.isSelected())
{
for (int a = 0; a < tbl_PettyReceipt.getRowCount(); a++)
{
String atCode = (String)tbl_PettyReceipt.getValueAt(iRow, 0);
String atAmount = (String)tbl_PettyReceipt.getValueAt(iRow, 3);
}
}
}
catch(Exception e){
System.out.println(e);
}
}

Anand - the previous post corrected your code but didn't tell you why it is correct. I am presuming that tbl_PettyReceipt is some sort of collection. When you put something into a collection, it is casted up to an Object. So, when you pull it out, you have an Object reference, even though the underlying object is actually a String. So, it has to be cast to a String before it can be assigned to the atCode or atAmount variable. Makes sense?

Hi, All -

Please use the CODE UBB codes when posting code snippets. Doing so makes reading the code much easier as it preserves the indentation.

Thanks!
