Given the following piece of code: class Student { public void talk(){} } public class Test{ public static void main(String args[]){ Student t = null; try { t.talk(); } catch(NullPointerException e){ System.out.print("There is a NullPointerException. "); } catch(Exception e){ System.out.print("There is an Exception. "); } System.out.print("Everything ran fine. "); } } what will be the result?
Answer:
In the output of the given piece of code, the following lines are printed on the output screen:
There is a NullPointerException. Everything ran fine.
Explanation:
In the given code
class Student {
public void talk(){} }
This is a Student class which has a function talk()
The following is the Test class
public class Test{
public static void main(String args[])
{ Student t = null; try { t.talk(); }
catch(NullPointerException e)
{ System.out.print("There is a NullPointerException. ");
} catch(Exception e)
{ System.out.print("There is an Exception. "); }
System.out.print("Everything ran fine. "); } }
The above chunk of code creates a Student class object named t which is set to null. A null value is assigned to "t" to indicate that it points to nothing.
In the program a method talk() is called on a null reference. This results in NullPointerException. This is a run time exception. Since no object is created so compiler will not identify this error and this error comes in run time.
The try statement defines a code chunk that is to be tested in case of errors when the code chunk is execute. This is basically used for exception or error handling. The catch statement defines a code chunk (one or two lines of code) that executes if an error occurs in try part (block of code).
Sometimes it is needed to create a reference of the object even before creating an object and this has to be initialized or assigned a value. So null is assigned to such an object reference.
If the talk() method is intended to do something to the object t, which points to nothing, then try throws NullPointerException to indicate this error.
Since the program attempts to use an object reference that contains a null value , so when the program is executed, the try part throws NullPointerException and catch part is executed to indicate this exception. The catch part that executes contains the following statement:
{ System.out.print("There is a NullPointerException. ");
So this message is printed at output screen followed by this statement System.out.print("Everything ran fine. "); } } message. The second catch will not execute as there is no other error in the program except for the NullPointerException. So the output is:
There is a NullPointerException. Everything ran fine.

/* missing code */
System.out.print(volume);
Which of the following can be used to replace /* missing code */ so that the code segment works as intended?
I. double baseArea = pi * r * r;double volume = baseArea * h;
II. double volume = pi * r * r;volume = volume * h;
III. double volume = pi * r * r * h;
a. I only
b. III only
c. I and III only
d. II and III only
e. I, II, and III
Answer:
The answer is "Option e".
Explanation:
In this question we calculating the volume of a cylinder, that's formula is:
[tex]\boxed{\text{Volume}= \pi \times r^2 \times h}[/tex]
In the above, we use π that's value is 3.14 or [tex]\frac{22}{7}[/tex] and "r and h" is input by the user. In the given choices all were correct it calculates the volume, that can be defined as follows:
In choice 1, The double variable "baseArea" is declared, which first calculates [tex]\pi \cdot r^2[/tex] value then multiply the h value and store it into the "volume" variable.In choice 2, The double variable "volume" is declared, which first calculates [tex]\pi \cdot r^2[/tex] value then multiply the h value and store it into the "volume" variable. In choice 2, The double variable "volume" is declared, which directly calculates the volume value by the above-given formula.What can you do to help create a safe online environment?

Imagine that a crime has been committed and being a police officer you have to investigate the case. Solving a crime can be a very complex problem as there are many things to consider. How will you decompose this problem?
Explanation:
On October 31, around twelve o'clock at night, the lights were dull. It was Siberian cold and I was walking painfully under the whitish lighting of a lamppost and the retro neon lights of a convenience store in a neighborhood that was buzzing when I went to buy meat. buildings, grayish in this half-light, crumbled under the weight of sleep, while the neighborhood was still open. Its decoration was particularly macabre in tone: synthetic but very sticky spider webs adorned the porches of the terraces, pumpkin ornaments are exhibited like works of art, ... Some pushed the macabre by hanging mannequins made up in corpses. At the entrance to the neighborhood, I found the body of its owner stabbed. Frozen in place, I wondered what else awaits me. My heart was pounding, feeling a shiver of anguish. When I was removing the phone from my pocket to call my police friends, my hands were clenched in fear. An investigation was carried out to find out the causes of death. Also, I went with them so they take my words. Hopefully the murderer will be arrested to put an end to this sybilinous crime.
An IT technician is applying a static IP address to a printer. Which piece of IP addressing information on the printer would allow the technician to check connectivity with a PC on a remote network?
Answer:
ip ADDRESS
Explanation:
These static IP addresses can be established on the device directly, for example using each computer's network settings on Windows, or they can be set at the router level. Although many people (and even some routers) still refer to it as a “static IP address,” doing it at the router level is referred to as assigning a DHCP reservation.
What IT technician is applying a static IP?Your computer's IP address lets the rest of the Internet know if it is running a web server. Internet-connected devices can have either a static IP address, which remains constant over time, or a dynamic IP address, which is subject to change over time.
A gadget with a static IP address assures that it can be found on the network easily because the IP address won't change.
Therefore, IP address allow the technician to check connectivity with a PC on a remote network.

When you write a program that will run in a GUI environment as opposed to a command-line environment, ____________.a. The logic is very differentb. Some syntax is differentc. You do not need to plan the logicd. Users are more confused
Answer: B. Some syntax is different
Explanation: The graphical user interface and the command line are both ways of interacting with our computer such that through them we can perform numerous functions very easily. However, the graphical user interface and the command line both offers different methods or ways of interaction with our computers. GUI's provides an interactive platform with our computer using visual icons and representarion, hence increasing usability especially for an average user. The command line on the other hand allows interaction with our computer through the use of text typed from the command line interpreter by following a defined syntax for each type of command or task to be performed.
Programs may be written and designed to run in ith environment, however application developers need to pay attention to the syntax due to the differences which exists while writing programs designed for each of the interfaces.
Write an algorithm that outlines how to calculate the room area for the image below.
Answer:
The following are the algorithm to this question:
Explanation:
Following are the steps of the algorithm:
step 1:
To calculate the area of the room, firstly we need to divide the given image into parts and calculate the area of the given image.
step 2:
After calculating each part area, we merge all the parts to calculate the areas.
Calculating area of the parts:
In part 1:
It forms the square shape, and the formula of the square is [tex]side \times side[/tex]. In this diagram we let A=B. that's why the area is [tex]b^2[/tex].
In part 2:
In this part also forms the square image. In this, the side is equal to (A-c). so, the area is equal to [tex](A-C)^2[/tex].
In part 3:
It forms the triangle shape, and the area of the triangle is[tex]= \frac{b \times h}{2}[/tex]. the value of "b" is E and the "h" is = (A-C). so, the area is [tex]= \frac{E\times (A-C)}{2}[/tex].
The total area is:
[tex]\bold{ =b^2+(A-C)^2+ \frac{E\times (A-C)}{2}}[/tex]
The algorithm that outlines how to calculate the room area is as follows:
StartInput A, B, C, D, EAreaRectangle1 = A x BAreaRectangle2 = (A - C) x (D - C - E)AreaTriangle1 = 0.5 x E x (A -C)Total = AreaRectangle1 + AreaRectangle2 + AreaTriangle1Print TotalStopFrom the attached figure, we can see that the figure has been split to 3
A rectangle with the dimension; A by BA rectangle with the dimension: (A - C) by (D - C - E)A triangle with the dimension base E and height (A - C).So, the algorithm is as follows:
