 Posted: Sat Mar 06, 2004 9:14 am Post subject: need help with the following code (vector) |
 |
|
I have the following code that pulls the menu items from a database
private JComboBox suppgrp = new JComboBox();
Vector SupGrps=SQL_stuff.getsuppliergroups();//this gets the supplier group
areas.
//here we need to setup the list
Object[] stArray = SupGrps.toArray();
for (int i = 0; i < SupGrps.size(); i++) {
String motherf =stArray[i].toString();
suppgrp.insertItemAt(motherf, i);
}
the setup sql code is
while (rset.next()) {
String[] record1 = new String[ColumnCount];
for (int i = 0; i < record1.length; i++) {
record1[i] = (String) rset.getString(i + 1); // COPY THE
DATA TO A LOCAL ARRAY OF THE RIGHT SIZE
}
loop++;
supgrp.addElement(record1);
}
but when displayed the list holds.
[Ljava.lang.String;@663a54
[Ljava.lang.String;@xxxxxx
[Ljava.lang.String;@xxxxxx
however both the vector SupGrps & the object stArray are showing the actual
strings when viewed in a debugger.
I guess it's " String motherf =stArray[i].toString();"
any ideas

Sorry too much time looking at the code
Obviously the correct solution is:
Vector SupGrps=SQL_stuff.getDatabaseArray(2);//this gets the supplier group
areas.(2 cols)
//here we need to setup the list
int i=0;
for (Iterator it=SupGrps.iterator(); it.hasNext(); ) {
Object element = it.next();
String[] stArray = (String[])element;
suppgrp.insertItemAt(stArray[0], i++);
}
