I'm beginner in Java. I really need to return DefaultTableModel
(javax.swing
) from array or ArrayList
. It is possible? I can't insert array into DefaultTableModel
(constructor).
Code is below:
private DefaultListModel model;
public DefaultListModel getNamesAndIdToCombobox(Connection conn, boolean closeConn, String sql) throws SQLException {
long counter = 0;
try {
Statement stmt =
conn.prepareStatement(sql);
ResultSet rs = stmt.executeQuery(sql);
while (rs.next()) {
// String longKey = (String)rs.getString(2);
try
{
jListList.add(new JListValues(rs.getLong(2), rs.getString(1)));
}
catch(SQLException sqlException){}
try
{
jListList.add(new JListValues(rs.getLong(2), rs.getLong(1)));
}
catch(SQLException sqlException){}
try
{
jListList.add(new JListValues(rs.getString(2), rs.getLong(1)));
}
catch(SQLException sqlException){}
counter++;
}
JListValues[] array = jListList.toArray(new JListValues[jListList.size()]);
model = new DefaultListModel(array); // HERE IT IS A PROBLEM
LOGGER.info("getNamesAndIdToCombobox result count: " + counter);
} catch (SQLException e) {
LOGGER.error("Error", e);
throw e;
} finally {
try {
if (closeConn == true)
conn.close();
} catch (Exception e) {/* null */
}
}
return model;
}
adding the following code for adding arraylist values to DefaultListModel
should work:
DefaultListModel<JListValues> model = new DefaultListModel<>()
for(JListValues val : array)
model.addElement(val);
