DbActivity dbconnection = new DbActivity();

Answer 1

public String selectItemID(){
returns only the last itemNo found and that is added to the Combobox. My suggestion would be to do this:public Vector selectItemID(){
Vector result = new Vector();
try {
statement = dbConnection.prepareStatement("select ItemId from ItemDetails");
ResultSet itemNumberResult = statement.executeQuery();
while(itemNumberResult.next())
String itemNo = itemNumberResult.getString(1);
System.out.println("itemNo " +itemNo);
result.add(itemNo); // add all found itemNos
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return result;
DbActivity dbconnection = new DbActivity();
Vector result= dbconnection.selectItemID();
itemno=new JComboBox(result); // construct Combo with Vector
//System.out.println("Result "+result);
