Question

I was faced this question while one of recent interview :

class1
{ 
  virtual getname();
  {//code here..}
}

class2:class1
{
  overrides getname();
  {//code here..}

}
class3:class2
{
  public new getname();
  {//code here..}

}

class4
{
  class1 obj=new class3();
  obj.getname();
}

now in class4 which class’s method will call ? why ? and what is call this concept in oops ?

Answer 1

The getname in class3 will be the only one that’s invoked.

It’s called Method Hiding

Simply put, if a method is not overriding the derived method, it is hiding it. A hiding method has to be declared using the new keyword.
