Question: 3

You create a new class named NewClass1 in a model. NewClass1 manipulates the CustTable table in the
protected method modifyCustTable.
NewClass1 has the following code:
class NewClass1
{
public static MainClass1 construct()
{
return new MainClass1();
}
protected void modifyCustTable()
{
...
}
}
In the same model as NewClass1, you create a new class named NewClass2. You want to run the code in
the modifyCustTable method from the callModifyCustTable method in NewClass2.
What is a correct example of calling the modifyCustTable method from NewClass2?

A. {
public static NewClass2 construct()
{
return new NewClass2();
}
public void callModifyCustTable()
{
NewClass1 newClass1 = NewClass1::construct();
newClass1.modifyCustTable();
}
}
B. class NewClass2
{
public static NewClass2 contsruct()
{
return new NewClass2();
}
public void classModifyCustTable()
{
newClass1.modifyCustTable();
}
}
C. class NewClass2 extends NewClass1
{
public static NewClass2 contsruct()
{
return new NewClass2();
}
public void callModifyCustTable()
{
this construct().modifyCustTable();
}
}
D. class NewClass2 extends NewClass1
{
public static NewClass2 construct()
{
return new NewClass2();
}
public void callModifyCustTable()
{
this.modifyCustTable();
}
}

Question: 4

You are writing a method to update the Customer reference field on a Sales order table record. You
begin
by writing the following code:
class ExampleClass
{
/// <summary>
/// Update the Customer reference field on the Sales orders table.
/// </summary>
/// <param name = "_salesId">
/// Sales order to update
/// </param>
/// <param name = "_customerRef">
/// Updated Customer reference value
/// </param>
public static void updateSalesTableCustomerReference(SalesId _salesId,
CustRef _customerRef)
{
SalesTable salesTable;
}
}
Which statement will complete the method?

A. salesTable = SalesTable::find(_salesId);
salesTable.CustomerRef = _customerRef;
salesTable.update();
B. update_recordset salesTable
setting CustomerRef=_customerRef
where salesTable.salesid==_salesId;
C. salesTable = SalesTable::find(_salesId, true);
salesTable.CustomerRef = _customerRef;
salesTable.update();
D. update_recordset salesTable
setting SalesId = _salesId
where salesTable.CustomerRef == _customerRef;
