Data being retrieve from PL/SQL is "???"

Question

Hi,
I follow the sample code shown in getting the data of PL/SQL using Java.
Please see below:
OracleCallableStatement stmt =(OracleCallableStatement)conn.prepareCall
( "begin ? := getEMpArray; end;" );
// The name we use below, EMPARRAY, has to match the name of the
// type defined in the PL/SQL Stored Function
stmt.registerOutParameter( 1, OracleTypes.ARRAY,"EMPARRAY" );
stmt.executeUpdate();
// Get the ARRAY object and print the meta data assosiated with it
ARRAY simpleArray = stmt.getARRAY(1);
System.out.println("Array is of type " + simpleArray.getSQLTypeName());
System.out.println("Array element is of type code "+simpleArray.getBaseType());
System.out.println("Array is of length " + simpleArray.length());
// Print the contents of the array
String[] values = (String[])simpleArray.getArray();
for( int i = 0; i < values.length; i++ )
System.out.println( "row " + i + " = '" + values<em> +"'" );
But when i view the data from java the data that is being fetch is "???". All the array data is like this "???". :(
But when i debug the PL/SQL the data is OK.
I dont know if this is a binary numbers or what.
I dont know how to solve this. And get the real data.
Please help.
By the way, i'm using eclipse as the IDE.
Thanks.</em>

Ok,here is the code.
if(nvl(values1,0) >= nvl(:cf_qty,0)) then
     return (nvl(value1,0)-nvl(value2,0));
else
     pck.p_count_first := pck.p_count_first + 1 ;
     pck.p_FGI(pck.p_count_first):= nvl(value2,0) - nvl(value1,0);
end if;
Here for First counter value stored as 1,
Second value stored as 1.
When I am retriving the values. like
if (pck.p_FGI.count > 0) then
PCK.p_count_second := pck.p_count_second + 1 ;
v_total := pck.p_FGI(pck.p_count_second) – VALUE3;
end if;
Here Value pck.p_FGI(pck.p_count_second) comes as 0 instead of 1.
Can you tell us why is this show value 0.
