Answer:

public Clock(int hours) {

this.hours = hours;

}

Explanation:

In Java programming language, Constructors are special methods that are called to initialize the variables of a class when a new object of the class is created with the new keyword. Consider the complete code for the class below;

public class Clock {

private int hours;

public Clock(int hours) {

this.hours = hours;

}

}

In this example above, an object of this class can created with this statement Clock myclock = new Clock(6); This is a call to the constructor and passes a parameter (6) for hours

Using Matlab programming I need to rotate the line defined by x,y by 45 degrees around 2,2

belka [17]

Answer:

% here x and y is given which we can take as

x = 2:2:10;

y = 2:2:10;

% creating a matrix of the points

point_matrix = [x;y];

% center point of rotation which is 2,2 here

x_center_pt = x(2);

y_center_pt = y(2);

% creating a matrix of the center point

center_matrix = repmat([x_center_pt; y_center_pt], 1, length(x));

% rotation matrix with rotation degree which is 45 degree

rot_degree = pi/4;

Rotate_matrix = [cos(rot_degree) -sin(rot_degree); sin(rot_degree) cos(rot_degree)];

% shifting points for the center of rotation to be at the origin

new_matrix = point_matrix - center_matrix;

% appling rotation

new_matrix1 = Rotate_matrix*new_matrix;

Explanation:

We start the program by taking vector of the point given to us and create a matrix by adding a scaler to each units with repmat at te center point which is (2,2). Then we find the rotation matrix by taking the roatational degree which is 45 given to us. After that we shift the points to the origin and then apply rotation ans store it in a new matrix called new_matrix1.

RUDIKE [14]

Answer:

The answer is "print 2".

The mail command, which is also known as the return path, bounce address, as well as mfrom, and sends the back address. This command is used to set the message receiver, order RCPT. It's also composed of the message for the header, and it is the empty line of the message body, and in this command to read the second message we use the print 2 message.
