Android : How to set Bluetooth Device adress and name in android BLE?

I want to set device name and address of Android Bluetooth LE device.

the class BluetoothDevice provides getter methods for name and address like

BluetoothDevice device;

device.getName();
device.getAddress();

But there is no visible constructor or setter methods for device name and address like

BluetoothDevice device;

device.setName();
device.setAddress();

Please guide how to get rid of the issue. Thanks
