Help with passing variables

[davedave22]

Hey guys, this is my first post here and i'm glad there are people out there willing to help. So here's my problem:

import java.util.*;
import java.lang.Math;

class Random 
{

	public static void main( String[] args) 
{

		int snumber;

		Scanner scan = new Scanner(System.in);
		System.out.print("Enter a value of n:  ");
		snumber = scan.nextInt();
			if (snumber == 0) 
{
               			System.out.println("Thanks for playing, and make it a great day! :)");
			System.exit(0);
 }
	while (100 > snumber || snumber > 500) 
{
	
System.out.println("So sorry. The value must be between 100 and 500 inclusively.");
		System.out.print("Enter a value of n:  ");
		snumber = scan.nextInt();
		if (snumber == 0) 
{ 
		System.out.println("Thanks for playing, and make it a great day! :)");
				System.exit(0);
}	


 		
}
	
}


	  public void getNumber(int num)  
{  
          System.out.print("n is " + num);  
}  
	
	





}

Well, this is a problem i've been having with java since i started using it this year. I'm trying to pass the variable "snumber" that the user has input into another method "getNumber". It compiles but i am not getting the print of "n is --" . Help is appreciated ;]

Java != JavaScript

The code you posted is Java. This is a Javascript forum, but I happen to be a Java programmer too....

PHP Code:

import java.util.*;
import java.lang.Math;

// Note: java.lang.Math has a method named random()... to make things less confusing we'll rename the class to "MyGame"
class MyGame
{
    // instance variable declaration
    private int snumber;
    private Scanner scan;
    
    // Constructor.
    public MyGame()
    {    // Initialize variables here.
        snumber = -1;
        scan = new Scanner(System.in);
    }
    
    // The game loop.
    public void runGame()
    {
        while (snumber != 0)
        {
            System.out.print("Enter a value of n or '0' to exit: ");
            snumber = scan.nextInt();
            if ( (snumber >= 100) && (snumber <= 500) )
            {    // Play your game here.
                // Note: this line calls the showNumber function which outputs the value of the Instance variable "snumber"
                showNumber();
            } else if (snumber != 0) // Avoids the exit case of Zero
            {    // Oops, bad number, try again.
                System.out.println("So sorry. The value must be between 100 and 500 inclusively.");
            }
        }
        // Nothing to do after this line, the program will exit.
        System.out.println("Thanks for playing, and make it a great day! :)");
    }
    
    // Main method get's called from a static context.
    public static void main( String[] args) 
    {    // Create a new MyGame object.
        MyGame application = new MyGame();
        // Start playing the game.
        application.runGame();
        
    }

    // Output the current n value.
    public void showNumber()  
    {    // outputs the number stored in the instance variable "snumber"
        System.out.println("n is " + getNumber());
    }
    
    // returns the snumber value
    public int getNumber()
    {
        return snumber;
    }

} 


Copy and paste this code into your text editor.
Save the file as "MyGame.java"

Compile via: javac MyGame.java

Run via: java MyGame

Moderator's note: Please move this to the Java / JSP forum.
