________ are the primary means of authentication for a user's computer and other networks and servers to which the user may have

inn [45]

Answer:

The answer to this question is "Password".

Explanation:

In computer science, any User's computer and networks and server is secured with the password to access all we use the password. for example, if we want to access any WiFi system or any User's computer. Then we will insert the password. If the password is wrong so we can't access the WiFi system or User's computer. similarly, If we want to access any server so we must know about the password. Then we use the server and change it's setting.

So the password is the primary means of authentication for all User's.

Write a Java program that can calculate and print out the area of a circle. The user enters data of the radius and its measureme

mezya [45]

Answer:

// program in java.

// package

import java.util.*;

// class definition

class Main

{

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

try{

// Scanner object to read input

Scanner scr=new Scanner(System.in);

// variables

double rad;

String unit1="in";

String unit2="ft";

String unit3="cm";

String unit4="m";

// ask user to enter radius

System.out.print("Enter the radius: ");

// read radius

rad=scr.nextDouble();

// check radius is negative or not

while(rad<0)

{

System.out.println("Radius can't be negative:");

// ask again to enter radius

System.out.print("Enter the Radius again:");

// read radius again

rad=scr.nextInt();

}

// ask user to enter the unit of measurement

System.out.print("Enter the unit (\"in\" for inch, \"ft\" for feet, \"cm\" for centimeter, and \"m\" for meter):");

// read unit

String unt=scr.next();

// calculate area

double area=3.14*rad*rad;

// print area and unit

if(unt.equals(unit1))

System.out.println(area+" inch.");

else if(unt.equals(unit2))

System.out.println(area+" feet.");

else if(unt.equals(unit3))

System.out.println(area+" centimeter.");

else if(unt.equals(unit4))

System.out.println(area+" meter.");

}catch(Exception ex){

return;}

}

}

Explanation:

Read radius of circle from user with Scanner object and assign it to variable "rad".Check the radius is negative or not.If the radius is negative ask user to enter radius again until user enters a positive radius.Then read the unit of measurement.calculate the area of circle and print area with unit.

Output:

Enter the radius: -4

Radius can't be negative:

Enter the Radius again:6

Enter the unit ("in" for inch, "ft" for feet, "cm" for centimeter, and "m" for meter):cm

Area of circle is 113.03999999999999 centimeter.

A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated.(1) Out

dimulka [17.4K]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

int userNum;

Scanner input = new Scanner(System.in);

System.out.print("Enter integer: ");

userNum = input.nextInt();

System.out.println("You entered "+userNum);

System.out.println(userNum+" squared is "+(userNum*userNum));

System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

int userNum2;

System.out.print("Enter another integer: ");

userNum2 = input.nextInt();

int sum= userNum + userNum2; int product = userNum2 * userNum;

System.out.println(userNum+" + "+userNum2+" = "+sum);

System.out.println(userNum+" * "+userNum2+" = "+product); } }

Explanation:

This declares userNum

int userNum;

Scanner input = new Scanner(System.in);

This prompts the user for input

System.out.print("Enter integer: ");

This gets user input from the user

userNum = input.nextInt();

Number (1) is implemented here

System.out.println("You entered "+userNum);

Number (2) is implemented here

System.out.println(userNum+" squared is "+(userNum*userNum));

System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

This declares another variable userNum2

int userNum2;

This prompts the user for another input

System.out.print("Enter another integer: ");

This gets user input from the user

userNum2 = input.nextInt();

This calculates the sum and the product

int sum= userNum + userNum2; int product = userNum2 * userNum;

Number (3) is implemented here

System.out.println(userNum+" + "+userNum2+" = "+sum);

System.out.println(userNum+" * "+userNum2+" = "+product);
