The Pet class has one instance variable called name. Dog inherits from Pet and adds an age instance variable. Identify any compiler errors in the program segment below. Explain what each error is and why it occurs. If we remove the statements with errors, so that the program runs, what output will be produced by the 2 print statements? Explain why you get that output.

Pet p = new Pet( No Name );

System.out.println(p); // what output is produced here? why?

p = new Dog(Fido, 5 );

System.out.println(p); // what output is produced here? why?

Dog d = new Pet( No Name );
