Answer / guest
I said , I will have a Base Class School , and 3 sub
classes for school , viz Admin Class, Eucation Class &
Trust Class. I will have an interface with 2 methods , viz
KinderGarden() and Hsc() and an implementation class for
these methods. The sub classes will extend School class and
implement this interface.

Answer / adarsh
I think the best way to do this would be to have an interface for school,Kinder Garden and Higher secondary .Make School as the super class and kinder garden and secondary as an interface which extends the school interface.Then we can have three classes Education,Admin and Trust and make this classes implement both kinder garden and Secondary interfaces

Answer / binoy
I would answer this different.
I would have a Class (Interface) called School.
I will have an Class (Interface) called Division extending
School.
Education , Admin and Trust would be instances of Division.
KinderGarten and Higher Secondary would be subclasses that
would implement the Division interface.
In real time scenario, KinderGarten or Higher secondary
would be implementing either Education,Admin or Trust
classes.
I am not sure if any of them are any methodes. All are to
be considered as classes instead of methods

3) Suppose you are a very rich person, having 50 rooms and you have lost the key for one of the room's. How effectively you can find this key? (Qs2 and Qs3 are related)
If I will write String s=new String("XYZ"); String s1=new String("XYZ"); if(s.equals(s1)){ sop("True"); } else{ sop("False"); } This program will give me "True". But When I am creating my own class suppose class Employee{ public Employee(String name); } Employee e= new Employee("XYZ"); Employee e1 = neew Employee("XYZ"); if(e.equals(e1)){ sop("True"); } else{ sop("False"); } Then it will give the output as "False". Can I know what is happening internally?
