Create an interface called Runner. The interface has an abstract method called run() that displays a message describing the meaning of run to the class. Create classes called Machine, Athlete, and PoliticalCandidate that all implement Runner. The run() should print the following in each class:
Machine - When a machine is running, it is operating.
Athlete - An athlete might run in a race, or in a game like soccer.
PoliticalCandidate - A political candidate runs for office.

public class Athlete implements Runner
{
public void run()
{
// write your code here
}
}

public class DemoRunners
{
public static void main(String[] args)
{
Machine runner1 = new Machine();
Athlete runner2 = new Athlete();
PoliticalCandidate runner3 = new PoliticalCandidate();
runner1.run();
runner2.run();
runner3.run();
}
}

public class Machine implements Runner
{
public void run()
{
// write your code here
}
}

public class PoliticalCandidate implements Runner
{
public void run()
{
// write your code here
}
}

public interface Runner
{
// write your code here
}
