Date return values and nullpointerexception

Question

Couple of problems I was hoping to find some help about:
First, I'm passing a String, Number and Date into a private static void method. The String and Number values are updated and returned / retrieved fine, but the Date isn't and holds it's original value. How do I get a Date value, updated within the method, to be returned?
Second, I get a NullPointerException from the following little slice of code. The Olistitem is a class created by JPub FYO.
Olistitem[] listItem = new OSyncEnumlistitem[2];
listItem[0].setNumbervalue( new BigDecimal(1) ); // It's expecting a BigDecimal.
Any ideas?
Thankyou for any help.

Answer 1

For the first one, probably need some source code to
answer.
Are you returning a new Date, or just the original
object?I'm trying to assign a new date value to the date object passed in and then retrieve the results into an array. Some source code:
//To call the method.
Object argsV[] = new Object[argsValue.size()];
argsValue.toArray(argsV);
method.invoke(null, argsV);
// The method itself.
public static void test(CramerVarchar first, CramerNumber second, java.util.Date third, SyncEnumList fourth) throws ParseException
try{
first.setValue("Test String Returned");
second.setValue(new BigDecimal(second.getValue().intValue() + new BigDecimal(1).intValue()));
String dateFormat = "dd-MM-yy HH:mm:ss";
String theDateString = new String ("15-07-03 10:24:05");
SimpleDateFormat date = new SimpleDateFormat(dateFormat);
third = date.parse(theDateString);
catch (SQLException e)
System.out.println("Error in tester");
Any clearer as to what I'm getting at?!
