Answer:

Option c is the correct answer for the above question.

Explanation:

The super is a keyword in java which is used to call the parent class constructor from the child class constructor, but the only one thing is important to write the super is the constructor that the super keyword needs to be written as a first-line where it is used.
The above question has three option which holds the constructor, in which option 1 and 2 holds the super keyword as the last line. So this option is not to hold the correct constructor.
But option 3 will hold the Super as the first line, Hence this is the correct use of the constructor.
And Only option c states about option 3 while the other is states about the other option. Hence option c is the correct answer.

Answer:

Uneven use of resources

Explanation:

Potential problem associated with supporting multi - user operation without hardware support is:

Uneven use of resources: In a situation where we assign a set of resources to user 1 and if a new user comes, then it would be difficult to allocate new resources to him. The processor would get confused between the two users. And the tasks would not be completed. This can affect task processing.

Develop an sec (single error correction) code for a 16-bit data word. generate the code for the data word 0101000000111001. show

Kipish [7]

Answer:

code = 010100000001101000101

Explanation:

Steps:

The inequality yields $2^{k} - 1 > = M+K$ , where M = 16. Therefore,

The second step will be to arrange the data bits and check the bits. This will be as follows:

Bit position number Check bits Data Bits

21 10101

20 10100

The bits are checked up to bit position 1

Thus, the code is 010100000001101000101

Assume there is a class AirConditioner that supports the following behaviors: turning the air conditioner on and off. The follow

Dafna11 [192]

Answer:

officeAC = new AirConditioner();

officeAC.turnOn();

officeAC = new AirConditioner();

officeAC.turnOn();

officeAC.setTemp(69);

Explanation:

In the first statement a new object of the class AirConditioner whose reference is assigned to the officeAC. new is a keyword which creates an object of the class.

Next statement uses the method turnOn(). Reference to the new object officeAC is used to invoke this method turnOn().

2) The first two statements works the same as in 1)

The last statement invokes a method setTemp() using the reference variable and passes the value 69 to this method to set the desired temperature.

I would say, "not those kinds of kernels, when I say kernel, I mean the core of your computers operating system.

A painting company has determined that for every 115 square feet or wall space, one gallon of paint and eight hours of labor wil

Kay [80]

The program to calculate the total paint cost and other values is given below.

#include <iostream>

using namespace std;

int main() {

int rooms, laborChrg = 18;

float paintChrg;

float feetPerRoom[rooms];

float paintReq, laborHrs, paintCost, laborCost, totalCost, totalsqft=0;

cout<<"Enter the number of rooms to be painted "<<endl;

cin>>rooms;

for(int i=0; i <= rooms; i++)

{

cout<<"Enter the square feet in room "<<endl;

cin>>feetPerRoom[i];

// shortcut operator which is equivalent to totalsqft = totalsqft + feetPerRoom[i];

totalsqft += feetPerRoom[i];

}

cout<<"Enter the cost of the paint per gallon "<<endl;

cin>>paintChrg;

laborHrs = (totalsqft/115)*8;

laborCost = laborHrs * laborChrg;

paintReq = totalsqft/115;

paintCost = paintReq * paintChrg;

totalCost = laborCost + paintCost;

cout<<"The number of gallons of paint required "<<paintReq<<endl;

cout<<"The hours of labor required "<<laborHrs<<endl;

cout<<"The cost of the paint is "<<paintCost<<endl;

cout<<"The labor charges are "<<laborHrs<<endl;

cout<<"The Total cost of the paint job is "<<totalCost<<endl;

return 0;

}

Explanation:

The header files for input and output are imported.

#include <iostream>

using namespace std;

All the variables are taken as float except labour charge per hour and number of rooms.

The user is asked to input the number of rooms to be painted. An array holds the square feet in each room to be painted.

cout<<"Enter the number of rooms to be painted "<<endl;

cin>>rooms;

for(int i=0; i <= rooms; i++)

{

cout<<"Enter the square feet in room "<<endl;

cin>>feetPerRoom[i];

totalsqft += feetPerRoom[i];

}

The above code asks for square feet in each room and calculates the total square feet to be painted simultaneously.

All the data to be displayed is calculated based on the values of labor charge per hour and gallons of paint needed, given in the question.

laborHrs = (totalsqft/115)*8;

laborCost = laborHrs * laborChrg;

paintReq = totalsqft/115;

paintCost = paintReq * paintChrg;

totalCost = laborCost + paintCost;

All the calculated values are displayed in the mentioned order.
