What will happen when you attempt to compile and run the following code?

class A implements Runnable{
      public void run(){
            System.out.println("run-A");
      }
}

public class Test{
      public static void main(String argv[]){
            A a = new A();
            Thread t = new Thread(a);
            System.out.println(t.isAlive());
            t.start();
            System.out.println(t.isAlive());
      }
}
