[gparLondon]

Why option A is not correct? I am using kindle edition, might be its old one(I purchased it in November-2014). I wrote this code which is fine.

Code: Select all

package com.oracle.certification.OnlyInheritance;

 class Sub extends Super implements Tone{
	
	public void go()
	{
		System.out.println("Go! Go! Go!");
	}

}

Code: Select all

package com.oracle.certification.OnlyInheritance;

public class Super {
	
	public static void main(String args[])
	{
		Super s=new Sub();
		((Tone)s).go();
	}

}

Code: Select all

package com.oracle.certification.OnlyInheritance;

 interface Tone {
	
	void go();

}
