I realize this was long ago answered but want to suggest an additional approach that avoids the nested try-with-resources double block.
public List<User> getUser(int userId) {
try (Connection con = DriverManager.getConnection(myConnectionURL);
PreparedStatement ps = createPreparedStatement(con, userId);
ResultSet rs = ps.executeQuery()) {
// process the resultset here, all resources will be cleaned up
} catch (sqlException e) {
e.printstacktrace();
}
}
private PreparedStatement createPreparedStatement(Connection con, int userId) throws sqlException {
String sql = "SELECT id, username FROM users WHERE id = ?";
PreparedStatement ps = con.prepareStatement(sql);
ps.setInt(1, userId);
return ps;
}
