ExecuteUpdate error

Question

Hi
Im having a stupid little error and cant see what it is that is causing it. Im trying to set up an admin to allow user to update values in the DB of an application. However, I was using the executeQuery statement and getting the NoResultSet found error.
I then realised I needed the executeUpdate(). I tried it but getting the following error:
DisplayQueryResults.java [178:1] incompatible types
found : int
required: java.sql.ResultSet
resultSet = statement.executeUpdate( query );
^
Here is the valid piece of code!
private void updateTable(int num, double rate) {
        try {
            String query = "UPDATE Banks SET Rate = " + rate + " WHERE Id = " + num + "";
            statement = connection.createStatement();
            resultSet = statement.executeUpdate( query );
            displayResultSet( resultSet );
        catch ( SQLException sqlex ) {
            sqlex.printStackTrace();
            JOptionPane.showMessageDialog(null, "Invalid SQL statement, Please try again");
    }Anyone have any ideas?

Hi thanx for your input,
However Im still getting that No ResultSet was produced. It updates the DB alright, but throws that error.
Heres the code as it stands...am I doing as you say?
private void updateTable(int num, double rate) {
try {
            // Create an updatable result set
            Statement stmt = connection.createStatement(
            ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
            ResultSet resultSet = stmt.executeQuery("UPDATE Banks SET Rate = " + rate + " WHERE Id = " + num + "");
            // Move cursor to the row to update
            resultSet.first();
            resultSet.updateDouble(6, rate);
            // Update the row; if auto-commit is enabled, update is committed
            resultSet.updateRow();
            displayResultSet(resultSet);
        catch (SQLException e) {  e.printStackTrace();  }
}
