Q: Suppose we write lists by listing the values of the elements between curly brace

Solution: A ) odd = [ 1,3,5,7,8,6,4,2 ] The contents of the list even gets appended to the list odd B ) odd = [ 1,2,3,4,5,6,7,8 ] The contents of the list odd gets sorted C ) odd = [ 1,3,5,7 ] The contents of list even gets removed from the list odd D ) odd = [ ] Since there are no elements of list even in the list odd , so no element is retained from the list odd therefore the list odd becomes empty PLEASE RATE !!

Question

Suppose we write lists by listing the values of the elements between curly braces. For example, the list [1, 3, 5, 7] represents a List of Integers, containing the first four odd numbers.

Let odd = [1, 3, 5, 7] and even = [8, 6, 4, 2].

Assume each of the following happens in sequence, that is, if odd is modified in one question, carry that value forward into the next question.

A. What is the contents of odd if we call odd.addAll(even)?

B. What is the contents of odd if we then call odd.sort(null)?

C. What is the contents of odd if we then call odd.removeAll(even)?

D. What is the contents of odd if we then call odd.retainAll(even)?

Thank you!

Explanation / Answer

Solution:

A ) odd = [ 1,3,5,7,8,6,4,2 ]

The contents of the list even gets appended to the list odd

B ) odd = [ 1,2,3,4,5,6,7,8 ]

The contents of the list odd gets sorted

C ) odd = [ 1,3,5,7 ]

The contents of list even gets removed from the list odd

D ) odd = [ ]

Since there are no elements of list even in the list odd , so no element is retained from the list odd therefore the list odd becomes empty
