Need code that satisfies the following in java using arduino board. explanation for it also needed!

Consider passing in the OLED object into the Listener class. You may also wish to pash in your Button and LED pin objects in order to use them inside the onPinChange() method. The value from the potentiometer should range from 0 to 1023. Why 1023. Because it's one less than 1024. That value comes from the fact that the analogue-to-digital converter (ADC) inside the Grove board's ATMEGA328 processor has a 10-bit quantizer. What does that mean? It means that it chops up voltages into just over one thousand pieces, from 0 volts to 5 volts. Your potentiometer outputs signals that range between these two values. The ADC will give a value of 0 for a 0 volt signal from the potentiometer a value of 512 for a 2.5 volt signal Voltage to ADC Quanta . a value of 1023 for a 5.0 volt signal. [ADC "Quanta"] . A value of 1022 for a 4.995 volt signal 1823 + - - - - - . A value of 1 for a 0.0049 volt signal 1824 512 + - "quanta" includes 10238 0 2.5v 5v [ Volts] Demonstrate that you can display the potentiometer value when you press the button. Values should range from 0 to 1023
