Answer:
See explaination
Explanation:
def readFileFirstLast(filename):
# doc string
''' Function accept the filename and opens the fle
and reads all lines and strips new line character and
stores first and last in a string and return that string'''
#eception handle if file not found
try:
#opening the file
f = open(filename)
#reading the first line and striping the ne line
string = f.readline().strip()
#iterating until last line
for line in f:
pass
#concate the last line after strip the new line character to the string
string = string + " " + line.strip()
#return the string
return string
except:
#if file not found
return "File not found"
#taking the file name from user
filename = input("Enter a file name: ")
#printing the doc string in function
print("\ndoc_sting: \n"+ readFileFirstLast.__doc__+"\n")
#printing the returned string by calling the readFileFirstLast()
print("output string :")
print(readFileFirstLast(filename))
Answer:
import java.awt.Point;
public class Line{
private Point point1, point2;
public Line(Point p1, Point p2){
point1 = p1;
point2 = p2;
}
public Point getP1(){
return point1;
}
public Point getP2(){
return point2;
}
public String toString(){
return "[( The " + point1.x + "," + point1.y + "), (" + point2.x + "," + point2.y +")]";
}
public static void main(String args[]){
Line lineObj = new Line(new Point(7,9), new Point(6,2));
System.out.println(lineObj.toString());
}
}
Explanation:
- Declare the points inside the class Line.
- Initialize the getters and setters method for the class.
- Define a toString method that returns the information in a formatted manner.
- Inside the main method, initialize an object with some values.
- Display the information by calling the toString method.
The protocol that should be used for establishing a secure network connection is SSH.
The following information is to be considered:
- SFTP is secure also it is a protocol for file transferring that applied SSH.
- IP, FTP, and DHCP should not be for safety purposes as they are not secure.
- SSH is a secured connection for the remote sites so here the SSH protocol should be used.
Therefore we can conclude that The protocol that should be used for establishing a secure network connection is SSH.
