java.math.BigDecimal cannot be cast to [Ljava.lang.Object;

List queryList = executeReadAllSQLQuery(queryString);
    for (Iterator i = queryList.iterator(); i.hasNext();) {
        Object values[] = (Object[]) i.next();
        FDetails pDetails = transform(values);
        fDList.add(pDetails);
        values = null;
    }

Error I am getting at line 3 : java.math.BigDecimal cannot be cast to [Ljava.lang.Object;

My transform function : 

private FDetails transform(Object[] values) {
    FDetails Details = new FDetails();
    Details.setPb((BigDecimal)values[0]);
    Details.setPm((BigDecimal)values[1]);
    Details.setEl((BigDecimal)values[1]);
    Details.setUl((BigDecimal)values[1]);
    return BalanceDetails;
}

Please help me resolve these issue.

This works very fine!. Please try this

    HashMap<String, Object> map = new HashMap<String, Object>();
    map.put("amt", "1000");

    System.out.println("Amount is::"
            + new BigDecimal((String) map.get("amt")));

How about this code:

@SuppressWarnings("rawtypes")
List<BigDecimal> queryList = executeReadAllSQLQuery(queryString);

FDetails details = new FDetails();
int i = 0;
details.setPb(queryList.get(i ++));
details.setPm(queryList.get(i ++));
...

fDList.add(pDetails);

Note: Calling fDList.add() inside of the loop is almost certainly wrong. The loop gets one value from the list but you want all five values from the list, create one instance of FDetails from those five values and add that single instance to fDList once

It's clear from error that your List queryList is in fact a list of BigDecimals. So this would be work

BigDecimal value = (BigDecimal) i.next();

but since it's not what you expect then executeReadAllSQLQuery returns wrong result

BTW for-each would look better anyway

for (Object obj : queryList) {
   ...

The below line is returning you a java.math.BigDecimal which you are trying to cast illegaly to Object[]. It seems yourqueryList is a List<java.math.BigDecimal>.

i.next(); // is returning you a  java.math.BigDecimal
