Answer 13

Question 14

True or False? If a SortedSet object contains references to String objects, the natural ascending sort would take the difference between upper case and lower case characters into account.

Answer 14

Question 15

True or False? A SortedSet object containing references to String objects will always take the difference between upper case and lower case characters into account when establishing the sort order.

Answer 15

Question 16

True or False? Specific sub-interfaces of the Collection interface can define requirements that do not apply to all sub-interfaces of the Collection interface.

Answer 16

Question 17

True or False? A collection that implements the List interface maintains its elements in ascending alphanumeric order.

Answer 17

Question 18

True or False? A collection that implements the List interface is an unordered collection.

Answer 18

Question 19

True or False? A collection that implements the List interface is allowed to contain duplicate values.

Answer 19

Question 20

True or False? The contracts of the methods in the List interface are the same as the contracts of the methods inherited from the Collection interface.

Answer 20

Question 21

True or False? The iterator method for the Collection interface returns an iterator over the elements in the collection in propersequence, where the sequence is determined by the numeric index.

Answer 21

Question 22

True or False? The iterator method for the List interface returns an iterator over the elements in the collection in proper sequence,where the sequence is determined by the numeric index.

Answer 22

Question 23

True or False? The SortedSet interface "guarantees that its iterator will traverse the set in ascending element order, sorted according tothe natural ordering of its elements (see Comparable ), or by a Comparator provided at sorted set creation time."

Answer 22

True.

Back to Question 22

Answer 21

False. The iterator method for the Collection interface returns an iterator over the elements in the collection where thereare no guarantees concerning the order in which the elements are returned by the methods of the Iterator object.

Back to Question 21

Answer 20

False. According to Oracle, "The List interface places additional stipulations, beyond those specified in the Collection interface, on the contracts of the iterator , add , remove , equals , and hashCode methods."

Back to Question 20

Answer 19

True. Unlike a collection that implements the Set interface, a collection that implements the List interface is typically allowed to contain duplicate values.

Back to Question 19

Answer 18

False. A collection that implements the List interface is an ordered collection (also known as a sequence) . According to Oracle, "The user of the interface has precise control over where in the list each element isinserted." Elements can be inserted and retrieved on the basis of their integer index (position in the list) using the following methods:

sure. what is your question?

20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
