Challenge: Tic-Tac-Toe (Report a problem) Detecting mouse clicks For this step of the challenge you will complete Tile's handleMouseClick method. The handleMouseClick method has two parameters: x and y which represent the coordinates of where the user clicked the mouse. When a user clicks inside a tile, that tile's handleMouseClick method should call that tile's onClick method. To check if the mouse click is inside of the tile, you will need an if statement that checks if: - the mouse click is on, or right of, the left edge of the tile - the mouse click is on, or left of, the right edge of the tile - the mouse click is on, or below, the upper edge of the tile - the mouse click is on, or above, the lower edge of the tile

A common measure of transmission for digital data is the number of bits transmitted per second. Generally, transmission is accomplished in packets consisting of a start bit, a byte (8 bits) of information, and a stop bit. Using these facts, answer the following:a. Compute the time required to transmit an image of 1200x800 pixels with 8 bits for gray of each pixel using a 50 M bits/sec. modem?

b.What would the time be at 3 M bits/sec, a representative of download speed of a DSL connection?

(c) Repeat a and b when the image is RGB colored with 8 bits for each primary color. f 20 colored frames per second

Answers

Answer: a) 0,19 seg. b) 3,2 seg. c) 11,5 seg. d) 192 seg.

Explanation:

a) For each pixel in the image, we use 8 bits + 1 start bit + 1 stop bit= 10 bits.

Number of Pixels: 800*1200= 960,000.
Bits transmitted: 960,000 x 10 = 9.6 * 10⁶ bits = 9.6 Mbits
if the modem is able to transmit up to 50 Mbits in a second, we can calculate how much time it will be needed to transmit 9.6 Mbits, using this equality:

50 Mbit = 1 sec
9.6 Mbit = x ⇒ t= 9.6 / 50 = 0.19 sec

b) If the modem speed changes to 3 Mb/s, all we need to do is just use the same equality, as follows:

3 Mbit = 1 sec
9.6 Mbit = x ⇒ t= 9.6 / 3 = 3.2 sec

c) Now, if we need to transmit a colored image , at a rate of 20 f/sec, we need to calculate first how many bits we need to transmit, as follows:

1 Frame= 800*1200* (24 bits + 3 start bits + 3 stop bits)= 28.8 Mbits
1 Second= 20 frames/ sec = 28.8 Mbits *20 = 576 Mbits.
If the modem speed is 50 Mb/s, we can use the same formula that we used for a) and b), as follows:

50 Mbit = 1 sec

576 Mbits = x ⇒ t= 576 / 50 = 11.5 sec

d) Same as c) replacing 50 Mb/s by 3 Mb/s, as follows:

3 Mbit = 1 sec
576 Mbits = x ⇒ t= 576 / 3 = 192 sec

The time that's required to transmit an image of 1200x800 pixels with 8 bits for gray is 151.6 million seconds.

How to calculate the time taken?

The time required to transmit an image of 1200x800 pixels with 8 bits for gray will be:

= (1200 × 800 × 8) / 50

= 151.6 million seconds.

The time needed to be at 3 M bits/sec, a representative of download speed of a DSL connection will be:

= 7.68/3

= 2.56 seconds.

Whichof following can be thrown using the throw statement?ErrorThrowableExceptionRuntimeExceptionAll of Given

Answers

Answer: Exception

Explanation: A throw statement is a statement that whenever it gets executed ,it stops the flow of the execution immediately. The throw statement has a throw keyword for stopping of the execution which is denoted as the exception. A checked or unchecked exception can only be thrown. The compiler of a program has the function of giving warning if there are chances of exception.

Obtain the 9’s complement of the following eight-digit decimal numbers:12349876

89009951

Answers

Answer:

87650123

10990048

Explanation:

We have to find the 9's compliment of the given numbers

Now for the given data

a) given = 12349876

9's complement of the given number is calculated as:

99999999 - 12349876

= 87650123

b) given number = 89009951

9's complement for the given number 89009951 is calculated as:

99999999 - 89009951

= 10990048

Write a method called allDigitsOdd that returns whether every digit of a positive integer is odd. Return true if the number consists entirely of odd digits (1, 3, 5, 7, 9) and false if any of its digits are even (0, 2, 4, 6, 8). For example, the call allDigitsOdd(135319) returns true but allDigitsOdd(9145293) returns false.

Raj, a recent graduate, has recently joined your organization as a Junior Business Analyst. He has been asked to conduct a Feasibility Analysis on whether to automate the process of software installation or not. If you were in Raj's place, based on which of these parameters would you identify if that process can be automated? Pick onea. Availability of software licensingb. Entering license number during installationc. Operating System being usedd. Software version being used

Answers

Answer:

a. Availability of software licensing

Explanation:

With feasibility analysis, we take into consideration economic, technical, legal, and scheduling factors to make sure that our project completes successfully. Acquiring license for a software can be free of cost or paid subscription. So a business analyst needs to make an account of the cost of accessing the software services. Also while automating a software installation process, it would require automatic authentication which would again require details of licensing. So in my best knowledge, analyzing availability of software licensing is a must and foremost step for a feasibility study.

2. Use inheritance to create a hierarchy of Exception classes -- EndOfSentenceException, PunctuationException, and CommaException. EndOfSentenceException is the parent class to PunctuationException, which is the parent class to CommaException. Test your classes in a Driver class with a main method that asks the user to input a sentence. If the sentence ends in anything except a period (.), exclamation point (!), or question mark (?), the program should throw a PunctuationException. If the sentence specifically ends in a comma, the program should throw a CommaException. Use a catch block to catch all EndOfSentenceExceptions, causing the program to print a message and terminate. If a general PunctuationException is caught, the program should print "The sentence does not end correctly." If a CommaException is caught, the program should print "You can't end a sentence in a comma." If there are no exceptions, the program should print "The sentence ends correctly." and terminate.
