accessing Object[] values in Java

Question

Hello,

Regarding to this image: link text

I have an object, 'rezultat', which has getters and setters. I wanna set for 'cli' attribute ( rezultat.setCli(String .....) ), and as string parameter it should be that m_objArray[0], so 'ADSL22675....' from that image. Expanding m_objArray there are 19 attributes i need to set for the 'rezultat' object attributes. But i don't know how to access them.

Array o = ocs.getArray(1);
Object[] obj = (Object[])o.getArray();
rezultat = new ListOfMdfTab();
for (int i = 0; i < obj.length; i++)
{
rezultat.setCli ((String)obj[0].<what>?); //i need here that m_objArray[0].
}

'ocs' is an OracleCallableStatament object type, so i need Array o = ocs.getArray(1); because that 1 index is the out parameter which is a complx type. Please help. Thanks!

Answer 1

This statement will return a String or will throw a clasCastException if the Object is not a string:

(String)obj[0]

If you're not sure if it is a String you could use

obj[0].toString()

OR

String.valueOf(obj[0])

Which will handle nulls more elegantly

Answer 2

STRUCT is an oracle class that implements the java.sql.Struct interface. This interface offers a getAttributes() method.

It's worth a try calling this method and hoping for the best, that the array that is returned is equal to the internal m_objArray.

In Java code:

rezultat.setCli(((java.sql.Struct)obj[0]).getAttributes()[0].toString());
