slava [35]

Zenmap is the graphical User Interface representation for NMAP Security Scanner. It is an open-source program designed to make NMAP easy for starters to use. Typically, it is used to collect and identify a list of hosts, OS, as well what services are running on them by using a port scanning tool. It is used specifically for the scanning and vulnerability phase of ethical hacking.

A network administrator who wishes to audit all the devices on a specific IP scheme in a network can use NMAP. The admin can go ahead and scan the ports to know exactly which ports are closed and which are opened.

In which of the following situations should you expect to provide your Social Security number?
sveta [45]
Hey there!

Some situations you'd need to provide your SSN include when applying for insurance through an insurance company, when applying for a loan or a credit card (or any other company that you're sending a credit application to), banks, investment advisors, and cash transactions over $10,000, such as when buying a car. Also, if you are going to college with financial aid, colleges will collect your SSN. If any other business requests your SSN, they are legally allowed to, however, it's optional. It's also optional when applying for a job at a company, but might affect your chances at getting the job depending on the employer who may want to get credit statistics on their potential employees. 

Hope this helped you out! :-)

Write a method so that the main() code below can be replaced by the simpler code that calls method mphAndMinutesToMiles(). Origi
defon

ANSWER

The JAVA program after simplification is as below.

import java.util.Scanner;

public class CalcMiles {

   

   // variables declaration

   static double milesPerHour;

   static double minutesTraveled;      

   static double hoursTraveled;

   static double milesTraveled;

   

   // method declared static

   public static void mphAndMinutesToMiles(double speed, double mins)

   {

       // computations to calculate distance travelled

       hoursTraveled = mins / 60.0;

       milesTraveled = hoursTraveled * speed;

       

       // result displayed on the screen  

     System.out.println("Miles: " + milesTraveled);

   }

   

   // Scanner object created inside main()

   // user input taken inside main()

   public static void main(String [] args)

   {

       Scanner scnr = new Scanner(System.in);

       System.out.println("Enter miles travelled per hour ");

       milesPerHour = scnr.nextDouble();

       System.out.println("Enter minutes required to travel ");

       minutesTraveled = scnr.nextDouble();

       

       mphAndMinutesToMiles(milesPerHour, minutesTraveled);

       

   }

}

OUTPUT

Enter miles travelled per hour  

2.3

Enter minutes required to travel  

1234

Miles: 47.30333333333333

EXPLANATION

The program is simplified as explained below.

1. User input is taken using the object of Scanner class.

2. This object of Scanner class can only be created inside main() method hence, user input can only be taken inside main().

3. The code to calculate the result is separated in another method, mphAndMinutesToMiles(). This method is declared with return type void since no value is returned.

4. After user input is taken in main() for miles travelled per hour and minutes required to travel, these values are passed as parameters to the mphAndMinutesToMiles() method.

5. These parameters are used in calculation part. The total miles travelled in total hours (obtained from minutes), is calculated. The code to display the result is added to this method.

6. Inside the main method, only the code to create Scanner object, code to take user input for two variables and code to call the mphAndMinutesToMiles() is included.

7. The variables are declared as static and declared at class level.

8. No variable is declared inside any of the two methods.
