Create a class named Console, and move all the methods that retrieve and validate user input to that class. These methods can re
otez555 [7]

Answer:

Here is the Console class:

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

public class Console {   // class name

public Console() {}   //class constructor

public int getInt(Scanner sc, String prompt) { //gets user's number  

int i = 0;   //initialize i to 0

boolean isValid = false;   // checks for valid input

while (!isValid) {   //loop iterates as long as input remains valid

System.out.print(prompt);   //displays prompt

if (sc.hasNextInt()) {   // checks for the next token (input number)

i = sc.nextInt();   // scans and reads the next number

isValid = true;   // checks if input is valid

} else {   //if input is not valid

System.out.println("Error! Invalid integer value. Try again.");  }  //displays error message

sc.nextLine(); // discard any other data entered on the line   }

return i;  }  //returns number

public int getIntWithinRange(Scanner sc, String prompt, //checks users guess if outside parameters or not  

int min, int max) {  

int i = 0;  

boolean isValid = false;   //sets isValid to false

while (!isValid) {   //keeps iterating and stops when isValid is false

i = getInt(sc, prompt);   //calls getInt method to get users number

if (i <= min) {   //if number is less than value of min

System.out.println("Error! Number must be greater than " + min);   //displays this message

} else if (i >= max) {   //if number is greater than that of max

System.out.println("Error! Number must be less than " + max);   //displays this message

} else {   //if guess is right

isValid = true;   } } //sets isValid to true

return i;  } //returns that number

public  String getRequiredString(Scanner sc, String prompt) { //Asks for user's string input  

String s = "";  

boolean isValid = false;   //sets isValid to false

while (!isValid) {      //keeps iterating and stops when isValid is false

System.out.print(prompt);    //displays prompt

s = sc.nextLine();   //reads next line (read next string input value)

if (s.equals("")) {   //if user enters nothing

System.out.println("Error! This entry is required. Try again.");   //display this message

} else {   //if user enters a string input

isValid = true;   }  }  //sets isValid to true

return s; }  //returns string

public  String getChoiceString(Scanner sc, String prompt, //Checks for users input for Y/y ignores caps  

String s1, String s2) {

String s = "";  

boolean isValid = false;   //sets isValid to false

while (!isValid) {   //iterates until isValid is false

s = getRequiredString(sc, prompt);   //calls method to get the input string

if (!s.equalsIgnoreCase(s1) && !s.equalsIgnoreCase(s2)) {  // checks users input for Y/y ignores caps  

System.out.println("Error! Entry must be '" + s1 + "' or '" + s2 + "'. Try again.");   // displays error message that entry must be y or Y

} else {   //if user enters y or Y

isValid = true;   } }   //sets isValid to true

return s;  } } //returns y or Y

public void displayWelcomeMessage() { //displays message  

System.out.println("Welcome to the Guess the Number Game");  

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

System.out.println(); }

public  void displayPleaseGuessMessage() { //displays message for user to guess from 1-100  

System.out.println("I'm thinking of a number from 1 to 100.");  

System.out.println("Try to guess it.");  

System.out.println();}

public  void displayCorrectGuessMessage(int counter) { //display user's current guess count

System.out.println("You got it in " + counter + " tries.");  

if (counter <= 3) {   //if user guesses the number in 3 or less tries

System.out.println("Great work! You are a mathematical wizard.\n");  

} else if (counter > 3 && counter <= 7) {   //if user guesses the number greater than 3 but less than or equals to 7 tries

System.out.println("Not too bad! You've got some potential.\n");  

} else {   //if user guesses the number after more than 7 tries

System.out.println("What took you so long? Maybe you should take some lessons.\n"); }}

public  void displayGuessAgainMessage(int number, int guessNumber) { //Asks user to guess again  

int difference = guessNumber - number;  

if (guessNumber > number) {   //if guessNumber is greater than number

if (difference > 10) {   //if difference between guessNumber and number is greater than 10

System.out.println("Way too high! Guess again.\n");   //guessed number is higher than correct one

} else {  

System.out.println("Too high! Guess again.\n");  }

} else {  

if (difference < -10) {   //if difference between guessNumber and number is less than -10

System.out.println("Way to low! Guess again.\n");   //guessed number is lower than correct one

} else {  

System.out.println("Too low! Guess again.\n");}}}}

If 200.123.4.6 is a classful internet protocol (ip) address, what class is it in?
REY [17]

200.123.4.6 is a classful internet protocol (ip) address located in class C.

An IP address (internet protocol address) is a numeric representation. This numerical representation uniquely identifies a particular interface on the network.

Address in IPv4 that has a length of 32 bits. This allows a maximum of 4,294,967,296 (232) unique addresses. Addresses in IPv6 are 128-bits long, which allows for 3.4 x 1038 (2128) unique addresses.

The total usable address pools of both versions are subtracted by the various reserved addresses and other considerations.

IP addresses can also be defined as binary numbers but are usually expressed in decimal form (IPv4) or hexadecimal form (IPv6) to make it easier for humans to read and use them.

I make a budget of my 1st Gamer PC its good?
svet-max [94.6K]

Answer:

Good start

Explanation:

I'm not <em>super</em> knowledgeable about computer hardware but the 16gb of ram seems like a good decision but the biggest thing I reccomend is allocating more money towards storage. Even just getting a normal HDD for your games might be a good idea because the newest CoD game is 84gb so you will fill that SSD up quicky.

For this project you will write a Java program that will run a simple math quiz. Your program will generate two random integers
ElenaW [278]

Answer:

Here is the JAVA program:

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

public class FunWithBranching {   //class name

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

   Scanner input = new Scanner(System.in);  //creates Scanner object

   System.out.print("Enter your name: "); //prompts user to enter name

   String userName = input.nextLine();  //stores the name

   System.out.print("Welcome " + userName + "! Please answer the following questions:\n");   //prompts user to answer the questions

   int randomOperand1 =  (int)(20 * Math.random()) + 1;  //generates random number for operand 1 (1-20)

   int randomOperand2 =  (int)(20 * Math.random()) + 1;  //generates random number for operand 2 (1-20)

   int randomAdd = randomOperand1 + randomOperand2;  //performs addition of two random numbers and stores result in randomAdd

   int randomMul = randomOperand1 * randomOperand2;  //performs multiplication of two random numbers

   int randomDiv = randomOperand1 / randomOperand2;  //performs division of two random numbers

   int randomMod = randomOperand1 % randomOperand2;  //performs modulo of two random numbers

   int correctAns = 0;  //stores number of correct answers

   System.out.print(randomOperand1 + " + " + randomOperand2 + " = ");  //displays random number + random number

   int AdditionGuess = input.nextInt();   //reads the answer of addition from user and stores it in AdditionGuess

   if (AdditionGuess == randomOperand1 + randomOperand2) {  //if the user answer is correct

   System.out.println("Correct!");  //displays correct

   correctAns++;  //adds 1 to the count of correctAns every time the user gives correct answer of addition

 } else {  //if user answer is incorrect

   System.out.println("Wrong!");  //displays wrong

   System.out.println("The correct answer is " + randomAdd);   }  //displays the correct answer of addition

   System.out.print(randomOperand1 + " * " + randomOperand2 + " = ");  //displays random number * random number  

   int MultiplicationGuess = input.nextInt();   //reads the answer of multiplication from user and stores it in MultiplicationGuess

 if (MultiplicationGuess == randomOperand1 * randomOperand2) {  //if the user answer is correct

     System.out.println("Correct!");  //displays correct

     correctAns++;  //adds 1 to the count of correctAns every time the user gives correct answer of multiplication

 }else{  //if user answer is incorrect

       System.out.println("Wrong!");  //displays wrong

       System.out.println("The correct answer is " + randomMul);   }  //displays the correct answer of multiplication

   System.out.print(randomOperand1 + " / " + randomOperand2 + " = ");  //displays random number / random number  

   int DivisionGuess = input.nextInt();   //reads the answer of division from user and stores it in DivisionGuess

   if (DivisionGuess == randomOperand1 / randomOperand2) {  //if the user answer is correct

       System.out.println("Correct!");  //displays correct

       correctAns++;   //adds 1 to the count of correctAns every time the user gives correct answer of division

       }else{  //if user answer is incorrect

           System.out.println("Wrong!");  //displays wrong

           System.out.println("The correct answer is " + randomDiv);     }  //displays the correct answer of division

      System.out.print(randomOperand1 + " % " + randomOperand2 + " = ");  //displays random number % random number  

       int ModGuess = input.nextInt();  //reads the answer of modulo from user and stores it in ModGuess

           if (ModGuess == randomOperand1 % randomOperand2) {  //if the user answer is correct

           System.out.println("Correct!");  //displays correct

           correctAns++;   //adds 1 to the count of correctAns every time the user gives correct answer of modulo

           }else{  //if user answer is incorrect

               System.out.println("Wrong!");  //displays wrong

               System.out.println("The correct answer is " + randomMod);    }  //displays the correct answer of modulo

double percentage = correctAns * 25;   //computes percentage

System.out.println("You got " + correctAns + " correct answers.");   //display number of correct answers given by user

System.out.println("That's " + percentage + "%!");         }  } //displays percentage
