Write a class Bug that models a bug moving along a horizontal line. The bug moves either to the right or left. Initially, the bug moves to the right, but it can turn to change its direction. In each move, its position changes by one unit in the current direction. Provide a constructor
Answers
Answer:
Following are the constructor to the given code:
Bug(int position) //defining a constructor that defines a integer parameters
{
this.position = position;//use this key word to hold parameter value
right = true;//defining a variable right that hold a boolean value
}
Explanation:
In this code, a constructor is declared that defines integer parameters with it, Inside the constructor, this keyword is used to holds the "position" parameter value and defines a boolean variable "right" that holds a boolean value.
Full program:
public class Bug //declaring a class Bug
{
private int position;//declaring integer variable position
private boolean right;//declaring boolean variable
public Bug(int position) //defining a parameterized constructor
{
this.position = position;//use this to hold position value
right = true;//holding boolean value
}
public void turn() //defining a method turn
{
right = !right;//holding value
}
public void move() //defining method move
{
if(right)//use if to check boolean value
{
position++;//incrementing position value
}
else//else block
{
position--;//decreasing position value
}
}
public int getPosition()//defining method getPosition
{
return position;//return position value
}
public static void main(String[] args) //main method
{
Bug bug = new Bug(10);//creating class object
System.out.println("Expected = 10, Actual = " + bug.getPosition());//calling method with printing value
bug.move();//calling method
System.out.println("Expected = 11, Actual = " + bug.getPosition());//calling method with printing value
bug.move();//calling method
bug.move();//calling method
bug.move();//calling method
System.out.println("Expected = 14, Actual = " + bug.getPosition());//calling method with printing value
bug.turn();//calling method
bug.move();//calling method
bug.move();//calling method
System.out.println("Expected = 12, Actual = " + bug.getPosition());//calling method with printing value
bug.turn();//calling method
bug.move();//calling method
System.out.println("Expected = 13, Actual = " + bug.getPosition());//calling method with printing value
}
}

because the password being used is of high quality
Explanation:
Option C is the most preferable in terms of system security because the password being used is of high quality. Meaning that it contains lower case and capital case letters as well as numbers. It is also a random mix of all three and is not a common word or name. The length of the password is normal but could be longer for better safety. These things make it very difficult and time-consuming for a software program to guess the password, and nearly impossible for an individual to guess.
Which of the following passes an int argument into a method named print? Chose one option and explain why.
o print();
o print()+5;
o print("5");
o print(5);
Answers
Answer:
print(5)
Explanation:
Passing an int argument into the method named print ;
print() ; Here, the print method has no argument as it is empty
print()+5; Here also, the print method has no argument and adding +5 is an invalid syntax.
print("5") ; Here, print takes in an argument, however, the argument is a string due to the fact that 5 is enclosed by quotation marks.
print(5) ; Here, the integer is 5 is passed to the print method.
Write a program to prompt the user for hours worked to compute a gross pay for an employee, and he is paid 100/hour. If he worked for 50 hours in a week then he will get overtime pay for the extra hours he worked i.e. he will be paid 1.5 times of M100.00 for 10 hours (50-40)
Answers
Answer:
rate = 100
hours_worked = eval(input('enter number of hours worked'))
gross_pay = hours_worked * rate
if hours_worked <= 40 :
print(gross_pay)
else:
print(gross_pay + (1.5*rate*(hours_worked -40)))
Explanation:
Using python 3 :
The rate of pay is defined using the rate variable
The user is the prompted to enter the number of hours worked.
Gross_pay gives the mathematical evaluation of the amount paid base in rate and hours worked.
Since hours beyond 40 are paid as overtime. Then we have to add that to those who worked above 40 hours.
If hours_worked is 40 and below, then use gross pay
If gross pay is above 40 ; then the overtime fee is added to gross pay using the rate provided.
Write a program that allows the user to enter the last names of five candidates in a local election and the number of votes received by each candidate.

void main()
{
int votes[20];
string name[10];
int total=0;
float percent[10];
int m, i, loc;
cout<<"Enter the names of candidates in local election and number of votes:"<
for(int i=0;i<5;i++)
{
cin>>name[i];
cin>>votes[i];
}
for(i=0;i<5;i++)
{
total=total+votes[i];
}
for(i=0;i<5;i++)
{
percent[i]=((votes[i]/total)*100);
}
cout<<"Candidate"<<'\t'<<"VotesReceived"<<'\t'<<"% of Total Votes"<
cout<
for(i=0;i<5;i++)
{

cout<<"Total:"<
m=findMax(votes);
cout<<"Winner of the election is"<
system("pause");

{
int i,max,loc;
max=votes[0];
for(i=1;i<5;i++)
{
if(votes[i]>max)
{
max=votes[i];
loc=i;
}
}
return loc;
}
But, it is saying that loc is not initialized, and it is also not calculating % of total votes or the winner of the election and I don't what to do to fix it.
Answers
Answer:
The following fix were made to the program
Change void main() to int main(), then set a return value at the end of the main function; e.g. return 0Remove system("pause"); It's not neededFor each of the array, change their lengths to 5 i.e. int votes[5]; string name[5]; and float percent[5];Lastly, calculate the percentage using: percent[i]=((votes[i]*100.0/total))Explanation:
(1) void main implies that the main function will not return any value. So, you change it to int main() and then set the return value
(2) There is no need to pause the program, so system.("pause") is not necessary.
(3) The question says there are 5 candidates. So, we set the arrays to accommodate inputs for 5 values
(4) percent array is declared as float; 100.0 will ensure that it calculates the percentage as a float value.

(d)
public class abstract Rectangle {
public abstract double findArea ( );

Answer:
(b)
public abstract class Rectangle {
public abstract double findArea ( );
}
Explanation:When a class is declared with the abstract keyword, the class is called an abstract class. Abstract classes cannot be instantiated and may include one or more abstract methods. If a class contains an abstract method, then it (the class) must be declared abstract.
In Java, abstract classes are defined using the following format:
[access_modifier] abstract class [name_of_class]
[access_modifier] specifies the access modifier of the class which could be public, private, e.t.c
abstract is the keyword that specifies that the class is an abstract class.
class is a keyword used for defining classes
name_of_class specifies the name of the class.
The only option that fulfils this format is option b where;
(i) The access modifier is public
(ii) The name of the class is Rectangle
Option a is not correct because the abstract keyword is supposed to come before the class keyword.
Option c is not correct because the keyword abstract is missing. In other words, the class must be declared abstract since it contains abstract method findArea();
Option d is not correct because the abstract keyword is supposed to come before the class keyword.
A programmer writes 500 lines of computer code in 17 days. Must there have been at least 1 day when the programmer wrote 30 or more lines of code
Answers
Answer:
The answer is No
Explanation:
Given data
Total Lines of code= 500
Number of days= 17 days
Number of codes written per day= 500/17
Number of codes written per day= 29.4117
If we multiply 29.4117 by 17
=499.9989
=500 approx
Hence there was never a day when the programmer wrote 30 or more lines

Answer:
When the present state is causes the next state to reset. ( e )

A finite state machine is a machine that can only be a certain state out its finite number of states at a given time. Hence state transitions occurs in a Finite state machine when the present state is causes the next state to reset.
An Example of a Finite state machine is a Coin-operated turnstile :
In this Finite state machine the Input of Coin unlocks the machine hence resetting the next state ( i.e. the lock state ), while to activate the lock state you push the arm of the Turnstile which in turn will as well reset the unlock state ( previous state ).

give one word • pressure exerted by a stationary liquid _______. • force in a direction perpendicular to a given surface area _______. • a pair of forces whose resultant is zero _______.
Answers
Answer:
1. Hydrostatic pressure.
2. Pressure.
3. Equilibrium forces.
Explanation:
1. Hydrostatic pressure: pressure exerted by a stationary liquid. It is simply the pressure in a liquid such as water at a specific depth.
Mathematically, hydrostatic pressure is given by the formula;
[tex] H.P = rho * g * d [/tex]
Where:
H.P is the hydrostatic pressure of a liquid.rho represents the density of a liquid.g is the acceleration due to gravity.d is the depth (height) of a liquid.2. Pressure: it is the force in a direction perpendicular to a given surface area. Thus, it's typically measured in Newton per meters (N/m²).
Mathematically, pressure is given by the formula;
[tex] Pressure = \frac {Force}{area} [/tex]
3. Equilibrium forces: a pair of forces whose resultant is zero. It is also referred to as balanced forces because the resultant of all the pair of forces acting on a body or system is at equilibrium (balanced).

a. The amount of time it takes guest users to send and receive large files is likely to decrease.
b. The number of packets required for guest users to send and receive data is likely to decrease.
c. Guest users will be prevented from having fault-tolerant routing on the Internet.
d. Guest users will be restricted in the maximum amount of data that they can send and receive per second.
Answers
Answer:
The correct option is d. Guest users will be restricted in the maximum amount of data that they can send and receive per second.
Explanation:
Bandwidth can be described as the maximum data transfer that an internet connection or a network has. It gives a measure of the amount of data that can be transmitted over a particular connection in a particular amount of time. For instance, the capacity of a gigabit Ethernet connection is 1,000 megabits per second (Mbps) (which also translates to 125 megabytes per second).
Therefore, when a local router is configured to limit the bandwidth of guest users connecting to the Internet, it will restrict the the maximum amount of data that they can transmit per second.
Therefore, the correct option is d. Guest users will be restricted in the maximum amount of data that they can send and receive per second.

Identify the correct statement regarding HTTP. a. Basic HTTP is a stateful protocol. b. In HTTP tunneling, some protocols travel inside HTTP traffic. c. It has been replaced with IPv6. d. It was developed by Al Gore.
Answers
Answer:
b. In HTTP tunneling, some protocols travel inside HTTP traffic.
Explanation:
a. HTTP is not a stateful protocol. It is a stateless protocol since the receiver is not allowed to store the state from previous requests. In other words, there is no need to keep track of the session information or status. Other examples of stateless protocol are UDP (User Datagram Protocol) and DNS (Domain Name System).
b. In HTTP tunneling, some protocols travel inside HTTP traffic. HTTP tunneling allows two devices to be connected together using network link with or without restrictions such as firewalls and access control lists. One way of implementing this HTTP tunneling is by using the regular HTTP methods such as POST, GET, PUT and DELETE.
In other words, HTTP tunneling allows certain protocols travel inside HTTP traffic.
c. HTTP has not been replaced with IPV6. They are different protocols performing different functions. IPV6 is an internet protocol addressing scheme invented to replace its predecessor IPV4.
d. HTTP was not developed by AI Gore. It was developed by Tim Berners-Lee and his team.
