Write the definition of a method named countPos that receives a reference to a Scanner object associated with a stream of input
NNADVOKAT [17]

Answer:

Here is the method countPos    

  static int countPos(Scanner input){ //method that takes a reference to a Scanner object

   int counter=0;  // to count the positive integers  

   int number; //to store each integer value

   if(input.hasNextInt()){ //checks if next token in this scanner input is an integer value

       number=input.nextInt(); //nextInt() method of a Scanner object reads in a string of digits and converts them into an int type and stores it into number variable

       counter=countPos(input); //calls method by passing the Scanner object and stores it in counter variable

       if(number>0) //if the value is a positive number

           counter++;    } //adds 1 to the counter variable each time a positive input value is enountered

   else    { //if value is not a positive integer

       return counter;    } //returns the value of counter

   return counter; } //returns the total count of the positive numbers

Explanation:

Here is the complete program:

import java.util.Scanner; //to take input from user

public class Main { //class name

//comments with each line of method below are given in Answer section

static int countPos(Scanner input){

   int counter=0;

   int number;

   if(input.hasNextInt()){

       number=input.nextInt();

       counter=countPos(input);

       if(number>0)

           counter++;    }

   else    {

       return counter;    }

   return counter; }

public static void main(String[] args) { //start of main function

       System.out.println("Number of positive integers: " + countPos(new Scanner(System.in)));  } } //prints the number of positive integers by calling countPos method and passing Scanner object to it

The program uses hasNextInt method that returns the next token (next input value) and if condition checks using this method if the input value is an integer. nextInt() keeps scanning the next token of the input as an integer. If the input number is a positive number then the counter variable is incremented to 1 otherwise not. If the use enters anything other than an integer value then the program stops and returns the total number of positive integers input by the user. This technique is used in order to avoid using any loop. The program and its output is attached

What is the name of the item that supplies the exact or near exact voltage at the required wattage to all of the circuitry insid
gizmo_the_mogwai [7]

Answer:

It's the <u><em>power supply</em></u>

Explanation:

The power supply is what essentially enables the computer to operate. It is able to do that by converting the incoming alternating current (AC) to direct current (DC) at the correct wattage rating that is required by the computer to function. The power supply is a metal box that is generally placed in the corner of the case.

Which of the following would be the most appropriate way to address and greet your teacher, Mr. Joseph Herman, in an email? Hi J
Valentin [98]
To determine what would be the most appropriate way to address and greet your teacher during an email, we should eliminate some greetings, such as:
"Yo wassup?", "How  u doin?", or any other grammatical and socially inappropriate errors.
Let's look at our first option.
"Hi Joseph, How u doin??". This is incorrect as it is not appropriate to address anyone in such a manner and with grammatical errors.
Let's look at our second option.
"Dear Joseph Herman, how are you doing!!". This was on the right path, but didn't end well. The ending of the message, "how are you doing!!" is incorrect punctuation, and has too much excitement.
How about our third option?
"Dear Mr. Herman, I hope you're doing fine.". This is a great email. It has perfect punctuation, grammar, and is appropriate.
What about our fourth?
"Dear Joseph, i hope you are doing great.". This is a good email, but has incorrect punctuation.
Your answer is C.) Dear Mr. Herman, I hope you're doing fine.

• What advantage does a circuit-switched network have over a packet-switched network? What advantages does TDM have over FDM in
lions [1.4K]

Answer:

Advantages of both circuit switched networks and TDM are given below:

Explanation:

Advantages of circuit switched network over packet switched network:

  • Circuit switched network has the advantage of being physically connected and having a dedicated channel for communication between the sender and the receiver which also makes it more reliable. Packet switched networks do not have a dedicated channel hence, they are not that reliable.
  • Circuit switched networks are used for voice calls because there is no timing jitter or delay in these types of networks while packet switched networks do not offer this advantage.

Advantages of TDM over FDM in a circuit switched network:

  • TDM is time division multiplexing i.e. multiple information is sent in different time intervals but on the same frequency. While FDM sends information using different frequencies. So, the advantage of using TDM is that the information will be sent from the sender to the receiver using only a single frequency.
  • Using TDM, bandwidth is saved because it only sends information on a single frequency unlike FDM.
  • In TDM, there is low chance of interference between signals since they are sent in different time intervals from the sender to the receiver. While FDM has a higher chance of interference.

Ivenika [448]

The input function reads a piece of data that has been entered at the keyboard and returns that piece of data, as a string, back to the program. This function is designed to accept data directly from the user, Similar function is the function raw_input() used in Python programming, which asks the user for a string of data (ended with a newline), and simply returns the string.
