    Default Methods

    Hi! I'm fairly new to Java and as ridiculous as this sounds, I'm having a difficult time wrapping my head around methods and how to execute them.
    For example, right now I'm making a game for class where the user guesses a number that a random generator pulls up. It's in one class right now called numbersTester but I want to have two classes (numbers and numbersTester) where numbers have the methods. I attempted to do this myself but I didn't know how to pull up the code in numbersTester correctly so I just put it in one class.
    Any feedback/help would be appreciated!

    import java.util.Random;
    import java.util.Scanner;

    public class NumbersTester extends Numbers {

    public static void main(String[] args) {

    Random number = new Random();
    int numberToGuess=number.nextInt(100);
    Scanner input = new Scanner (System.in);
    boolean win = false;

    int numberOfTries = 0;
    int guess;

    while (win == false){
    System.out.println("Guess a number between 1 and 100: ");
    guess = input.nextInt();
    numberOfTries ++;

    if (guess == numberToGuess){
    win = true;
    }

    if (guess > 100 || guess < 0){
    System.out.println("Invalid number!");
    }

    else if (guess < numberToGuess){
    System.out.println("The number is too low! Guess again.");
    }
    else if (guess > numberToGuess){
    System.out.println("The number is too high! Guess again.");
    }

    }

    System.out.println("\n" + "Game Over! " + "\n" + "You guessed correctly.");
    System.out.println("The answer was: " + numberToGuess);
    System.out.println(numberOfTries + " tries.");

    }

    }

    Default Re: Methods

    You already know how to do this. I imagine you have used Strings before and called many of its methods. In the code above you have a Random object and a Scanner object and manage to call methods of those classes. So why does it have to be so difficult when you write your own class?
