Hi, We will learn how to parse hex int number parse use bitwise operation let's do it int hexNum = (int) 0xabcd; System.out.println("hexNum binary string " + Integer.toBinaryString(hexNum)); System.out.println("hexNum hex string " + String.format("%02x",hexNum)); // 02 is number of digits // lets get ab System.out.println("hexNum binary string " + Integer.toBinaryString(hexNum&0xFF)); // multiplay by ff System.out.println("hexNum hex string " + String.format("%02x",(hexNum&0xFF))); // 02 is number of digits // lets get cd System.out.println("hexNum binary string " + Integer.toBinaryString((hexNum>>8))); //8 bit shift rigth System.out.println("hexNum hex string " + String.format("%02x",(hexNum>>8))); // 02 is number of digits //8 bit shift rigth

https://docs.oracle.com/javame/config/cldc/rel/3.4/core/da/html/device_access/uart.htm#CIHFBAAG 13 UART The com.oracle.deviceaccess.uart package contains interfaces and classes for controlling and reading and writing from/to Universal Asynchronous Receiver/Transmitter (UART), with optional Modem signals control. In order to access and control a specific UART device, an application should first open and obtain an UART instance for the UART device using its numerical ID, name, type (interface) and/or properties. Example 13-1 and Example 13-2 demonstrate how to use the UART APIs to communicate with a host. Example 13-1 Communicating using the UART API import com.oracle.deviceaccess.PeripheralException; import com.oracle.deviceaccess.PeripheralManager; import com.oracle.deviceaccess.uart.UART; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; public class UARTExample1 { UART host = null; InputStream is = null; OutputStream os = null;...

Answers included! Image for post Photo by Joshua Ness on Unsplash Below you’ll find a list of Java interview questions and answers I’ve gathered during my own job hunts. Before you continue, please note that answers may not be 100% complete, up to date, or optimized, but are in my experience sufficient for interview situations. OOP Questions These questions apply not only to Java, but object oriented languages in general. 1. Compare interfaces and abstract classes Both are used to achieve abstraction. Neither can be instantiated. An abstract class can have concrete i...
