Answer:
Please find the code and its output in the attached file.
Explanation:
In the above-given code, an interface "Runner" is defined, inside the interface, an abstract method run is declared.
In the next step, three class "Athlete, Machine, and PoliticalCandidate" s defined that implements the run method, and use the print message that holds a given value as a message.
In the next step, a class "DemoRunners" is defined, and inside the main method, the three-class object is declared, which calls the run method.

Answer: network topology is the arrangement of nodes which includes routers and switches so that enables connection between the server and the client.
however due to times when there is huge traffic in the nodes there needs to be an optimal path for the exchange of information which is accomplished by different routing protocols.
Explanation:
Routing Information Protocol(RIP) is one such protocol which enables to route packets from the source to the destination having the least possible traffic along its path. There are two sets of routing algorithm which are
1. Static routing protocols
2. Dynamic routing protocols.
The difference between the two is that dynamic routing protocols helps to construct the routing tables dynamically as compared to static routing.
RIP is a type of dynamic routing whereby it sends the contents of its routing table the adjacent routers every 30 seconds and whenever a route is discarded from the routing table it is marked as unusable.
RIp is supported by almost all routers and also supports load balancing which is one of it advantages.
Answer: Twisted pair cabling in the shielded form can be used for the mentioned situation in the question
Explanation: Twisted pair cables in shielded form are easy to make a connection .It does not create lot of noise and has reduced cross talk .It is a low weighted cable and so it can be easily attached with the ceiling tile.
The maintenance of the complete cabling is not a issue and interference is also low that fulfills the requirement of disruption-less network signal.The overall costing of the cable is also less .Thus shielded twisted pair cable are the most appropriate cable for the mentioned situation.
The answer is an RFID tag. Its a device capable of sending short-range signals, therefore making it capable of sending identifying information to a receiver placed close to the tag.
