Answer 1

Answer #1

1.)

An inner class iterator must implement the Iterator interface
Answer: Iterator interface

2.)

When an abstract data type has more number of operations on a single data, it is called interface bloat.
Answer: Interface bloat

3.)

a b - c d / + can be conveted to infix notation as (a-b)+(c/d)
(a-b)+(c/d) = (10-6) + (12/2) = 4 + 6 = 10
Answer: 10

4.)

a b - c - d / + is not a valid expression, it does not have enough number of operands to perform the given operation
Answer: cannot be determined
