The output of the given code is "AB-2".

Explanation:

The description of the java program can be given as:

In this program firstly we define a class that is "A". In this class, we define a private integer variable that is "myNum" and parameterized constructor and pass an integer variable that is "x" and use a private variable to holds the constructor variable value.Then we define three function that is "getNumber(), getLetters() and getMessage()" this function we returns values. Then we define another class that is "AB" which inherits the base class "A". In this class we define parameterized constructor and two methods that is "getNumber() and getLetters()". In the parameterized constructor and getNumber() method we use a super keyword that calls above(base class methods) and increases the value by 1. In getLetters() method we return value that is "AB". In calling time we create a class object that is "test", and call the AB class and pass value 0 in the parameter, and call the getMessage() method.

That's why the output of this program is "AB-2".

Local area networks use many of the same network technologies and the internet, only on a smaller scale. devices that access lans are equipped with a network interface that contains circuitry for wireless or wired connections. devices also have a physical address, in addition to the ip addresses acquired from a dhcp server. the most popular wired technology is . the most popular wireless technology is , which can be configured as a(n) or star topology. setting up a lan and configuring its router is fairly easy. the first step is to change the standard to one that is secure. next, create a(n) that uniquely identifies the network by name. it is also important to activate wireless to prevent wireless signals from being intercepted during transmission. a limited-access network can be created for visitors to use. by activating , the router will be able to assign ip addresses to each device that joins the network. to connect to a secure lan that is protected by encryption, an encryption , or password, is required. lans can be used to access data collected by iot devices and the networks that tie these devices together. technologies such as rfid, nfc, bluetooth smart, zigbee, and z-wave offer -power links, essential for battery-powered devices that can’t expend excess amounts of energy transmitting data.
