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");}}}}
