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
Explanation:
Here is the Game class
public class Game {  // class name
 public Game() {}   //class constructor
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");}}}}
