The _____ class can be used to get user input using dialog boxes.

Ber [7]

Answer:

JOptionPane

Explanation:

The class "JOptionPane" are used to pop / create dialogue boxes for the user to enter the input for a question.
JOptionPane contains methods to create input dialogue boxes, message dialogue boxes, option dialogue boxes and confirm dialogue boxes.
The dialogue boxes can be just message dialogue boxes which gives some message to the user. It doesn't require anything to be input from the user. It is just a message box.
Where as input dialogue box requires the user to input something.
Confirm dialogue box asks the user to answer a question yes / no / cancel.
Option dialogue box asks the user to select the options.
So, option (d) JOptionPane is the answer for the question.
Option (a), (b) and (c) are used for different purposes but not to create dialogue boxes. So, options (a), (b) and (c) are not the correct answers for the question.

Which of the following shows a list of Big-Oh running times in order from slowest to fastest?

Rufina [12.5K]

Answer:

O(N!), O(2N), O(N2), O(N), O(logN)

Explanation:

N! grows faster than any exponential functions, leave alone polynomials and logarithm. so O( N! ) would be slowest.

2^N would be bigger than N². Any exponential functions are slower than polynomial. So O( 2^N ) is next slowest.

Rest of them should be easier.

N² is slower than N and N is slower than logN as you can check in a graphing calculator.

NOTE: It is just nitpick but big-Oh is not necessary about speed / running time ( many programmers treat it like that anyway ) but rather how the time taken for an algorithm increase as the size of the input increases. Subtle difference.

Create the following matrix M: 1 7 13 19 25 ?-3 9 15 21 27 5 11 17 2329By writing one command and using the colon to address ran

zimovet [89]

Answer:

Matlab code is:

>> $M=reshape(1:2:29, 3,5)$

>> $\% (a)$

>> $Va=M(3,:)$

>> $\% (b)$

>> $Vb=M(:,4)$

>> $\% (c)$

>> $Vc=[M(2,:) M(:,3)']$

Explanation:

>> $\% \ Making\ the\ Matrix\ With\ required\ terms\ 1\ to\ 29\ with\ spaces\ of\ 5\ in\ three\ rows$

>> $M=reshape(1:2:29, 3,5)$

$M =$

1 7 13 19 25

3 9 15 21 27

5 11 17 23 29

>> $\% (a)$

>> $\%\ Slicing\ M\ \ from\ third\ row\ till\ end$

>> $Va=M(3,:)$

$Va =\\\ 5\ 11\ 17\ 23\ 29$

>> $\% (b)$

>> $\% \ Slicing\ the\4th\ column\ of\ M\ matrix\$

>> $Vb=M(:,4)$

$Vb =\\ 19\\ 21\\ 23\\$

>> $\% (c)$

>> $\% \ slicing\ the\ 2nd\ row\ and\ 3rd\ column\ of\ M\ Matrix\ and\ combining\ them\ to\ make\ a\ row\ matrix$

>> $Vc=[M(2,:) M(:,3)']$

$Vc =\\ 3\ 9\ 15\ 21\ 27\ 13\ 15\ 17$

The code is tested and is correct. If you put a semi colon ' ; ' at the end of every statement then your answer will be calculated but matlab doesn't show it until you ask i.e. typing the variable (Va, Vb, Vc )and press enter.
