Question

This is a basic Java Question referencing Chapter 5 methods. The goal is to make a quick program that has the computer guess a number, after which the user will input if they would like to play the easy, medium or hard level. After this point the user will be allowed to guess a certain amount of times, before the computer tells them they are correct, incorrect, and gives them the guessed number.

The Question is as follows:

Define a 'Guess the Number Game' with the following characteristics

a. The game picks a random number between 1-50 (key)

use random to get this number

b. The player needs to guess a number between 1-50

c. Ask player which level he or she wants to play with

-hard gets 3 chances (method)

-medium gets 6 chances(method)

-easy gets 10 chances(method)

D. If the player guesses a number less or greater than the key, a prompt is shown - "key is greater/lesser than the guess number"

E. If the player can pick the key in given number of attempts, prompt -- "You won!", else prompt "you loose."

This is what I have put together so far, I feel as though I may have it disorganized or in the wrong order.

import java.util.Random;
import java.util.Scanner; //import the scanner to display the text at the end

public class ChapterFivePractice { //Counting the number of conversations at Jeff Bezos Party.

public static void main(String[] args) { //method game picks a random number between 0 to 50

    Scanner scan = new Scanner(System.in);
    System.out.println("Please enter the level of play. Press 1 for Hard, Press 2 for Easy, Press 3 for Medium: " );

int levelOfDifficulty = scan.nextInt();
        if (levelOfDifficulty == 1){
            getlevelHard();
        }
        if (levelOfDifficulty ==2){
            getlevelEasy();
        }
        if (levelOfDifficulty == 3){
            getlevelMedium();
        }
        else {
            System.out.print("invalid Entry");
        }

    while (correct == false) { //this will start our main algorithm letting the user know if their guess is correct
        if (guess == numberToGuess) {
        correct = true;
    }
        else if (guess < nummberToGuess) {
        System.out.println("your guess is too low");
        }
        else if (guess > numberToGuess) {
        System.out.println("your guess is too high");
        }
} //end of loop

System.out.println("you win!");
System.out.println("The number was " + numberToGuess);
System.out.println("It took you " + numberOfTries + " tries");

} // end of main method

   public static int getlevelHard() {
    int levelHard;
    levelHard = 1;
    while (numberOfTries<=3){
        numberOfTries++;
    return;
    }
}
public static int getlevelMedium() {
    int levelMedium;
    levelMedium = 3;
    while (numberOfTries<=6){
        numberOfTries++;
    return;
    }
}

public static int getlevelEasy() {
    int levelEasy;
    levelEasy = 2;
    while (numberOfTries<=10){
        numberOfTries++;
    return;
    }
}

} //end of main class

}
