is this a correct way to use java.sql.Statement?

private void theMethod() throws java.sql.SQLException{
    int tmpAmount = -1;
    java.sql.Statement statement = connection.createStatement()

    java.sql.ResultSet rs = statement.executeQuery("SELECT amount FROM account_table WHERE num = '2' ");

        tmpAmount = rs.getInt("amount");

    if(tmpAmount > 0){
        statement.executeUpdate("DELETE FROM records WHERE account_num = '4'");
        statement.executeUpdate("DELETE FROM supplimental WHERE id = '4' ");
        statement.executeUpdate("UPDATE account_table SET amount = 0 WHERE num = '2'");

Is it OK to reuse "statement" like this, or is there some other steps necessary?

thats fine, the only thing you have to worry about is only having one result set open on a statement at a time
