Q6. Can instance variables be overridden
Ans. 
Yes, instance variables can be overridden.
• Instance variables can be overridden in subclasses.

• The subclass can declare a variable with the same name as the superclass variable.

• The subclass variable will then override the superclass variable.

• This is known as variable shadowing.

• Example: class A has an instance variable 'x', class B extends A and also has an instance variable 'x', B's 'x' will override A's 'x'.

Q11. Which is fastest between java 8 intermediate and terminal operations
Ans. 
Java 8 intermediate and terminal operations have the same speed.
• Intermediate operations are lazy and do not execute until a terminal operation is called

• Terminal operations trigger the execution of the entire stream pipeline

• The speed of intermediate and terminal operations depends on the size of the stream and the complexity of the operations

• Therefore, it is not accurate to say that one is always faster than the other
