Consider a scenario where all Cars will have 4 tyres and other features can be different.
In this case any subclass of Car has to have 4 tyres. This is a case where abstract class will be used and a default implementaion for tyres will be provided.
public abstract class Car{
public abstract String getCarName();
public final int getNoOfTyres(){
return 4;
}
}
Consider a scenario where Cars can have any number of tyres and other features can also be different. In this case interface will be created.
public interface Car{
public abstract String getCarName();
public abstract int getNoOfTyres();
}
