Use recursion to develop a method, printTree, that displays the folder tree under a given path along with the total size of each folder/subfolder (the method does not display any files). A sample output is given below. The numbers on the far right are folder sizes in Bytes. Note how the parent folders are displayed above their subfolders. Try to format the output so that it matches the sample below. Do not worry too much about the order of the subfolders (e. g. they do not have to be sorted). You may develop and use helper methods. You can only import File and Stack classes. You are not allowed to import any other java libraries or readymade libraries from the internet

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.
