Stock Program, exclude

[Avey]

Hey all, I'm writing a program that will eventually be able to store information about stocks and individual customers that will be able to buy and sell the stock.

How does one create a menu in which you'd select an option or exit the application?

Here's my code... (may or may not be necessary to see, but what the hell.)

public class broker {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Stock Stock1 = new Stock(); // this is a stock in the market (not with a customer)
		
		Stock1.setname("STK1");
		Stock1.setprice(8);
		Stock1.setvolume(10000);
		
		// make other stocks as given
		
		System.out.println(Stock1.toString()); // output stock1 info
		
		Customer customer1 = new Customer("C1", 100000); // creating a customer with a name C1 and balance 100000
		
		System.out.println(customer1.toString());// output all customer1 info
		
		// create other customers 
		
		// now do the trading
	}

}

These next two are both classes i will be using...

public class Stock {

	private String sname;
	private double sprice;
	private int svolume;
	
	public Stock()// constructor
	{
		sprice = 0;
		svolume = 0;
	}
	
	public void setprice(double p)
	{
		sprice = p;
	}
	public void setvolume(int v)
	{ 
		svolume = v;
	}
	public void setname(String s)
	{
		sname = s;
	}
	
	public String toString()
	{
		String out = "";
		
		// add to out
		
		return out;
	}

}

And.....

public class Customer {
	
	private String name;
	private double balance;
	
	Stock s1, s2, s3, s4;  // portfolio
	
	public Customer(String n, double b)
	{
		name = n;
		balance = b;
		s1 = new Stock();
		s2 = new Stock();
		s3 = new Stock();
		s4 = new Stock();
		
		
		s1.setname("STK1");
		s2.setname("STK2");
		s3.setname("STK3");
		s4.setname("STK4");
		
	}
	
	
	public String toString()
	{
		String output = "";
		
		// add to output - get s1.toString() on this for stock info
		
		return output;
	}
}

The menu only needs three options the user can select, one will buy stock, one will sell, and one will terminate the application. I simply don't understand how to create the menu, though I can deal with coding the actions the menu options actually execute.

Thanks for any help

Um, the question is about a console application, not a GUI.

How does one create a menu in which you'd select an option or exit the application?

Sorry, to me, menu is a GUI component, like JMenu/JMenuBar. Sorry if I was off-base there!

A menu can also be a console program which offers to choice some entries with a number example

1 New stock
2 List stocks
3 Delete stock
4 Exit

To be sure the op should tell us if he wants a console choice or a JMenu/JMenuBar!

Hey again guys, thanks for the responses. I'm just using JOptionPane.showOptionDialog to show the choices and using an array for my choices. I simply am not sure how to associate the SuccessfulBuy/Sell methods only affect which stock they choose. Here's a revamped skeleton of my program.

import javax.swing.JFrame;
import javax.swing.JOptionPane;


public class Customer {
	
	private String name;
	private double balance;
	double stockPrice;
	
	Stock s1, s2, s3, s4;  // portfolio
	
	String[] anArray = { "STK1", "STK2", "STK3", "STK4" };
	
	public Customer(String n, double b)
	{
		name = n;
		balance = b;
		s1 = new Stock();
		s2 = new Stock();
		s3 = new Stock();
		s4 = new Stock();
		
		s1.setname("STK1");
		s2.setname("STK2");
		s3.setname("STK3");
		s4.setname("STK4");
		
	}
	
	public double getBalance()
	{
		return balance;
	}
	
	public double SuccessfulBuy(String stockName, int stockBoughtAmt, double stockBoughtPrice)
	{
		int buyArray = JOptionPane.showOptionDialog(null, "Which Stock would you like to buy?", "Stock Broker", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, anArray, anArray[3]);
		
		if(buyArray == 0) //STK1
		{
			
		}
		if(buyArray == 1) //STK2
		{
			
		}
		if(buyArray == 2) //STK3
		{
			
		}
		if(buyArray == 3) //STK4
		{
			
		}
		
		return balance = balance - (stockBoughtAmt*stockBoughtPrice);
		
		
	}
	
	public double SuccessfulSell(String stockName, int stockSoldAmt, double stockSoldPrice)
	{
		int sellArray = JOptionPane.showOptionDialog(null, "Which Stock would you like to buy?", "Stock Broker", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, anArray, anArray[3]);
		
		if(sellArray == 0) //STK1
		{
			
		}
		if(sellArray == 1) //STK2
		{
			
		}
		if(sellArray == 2) //STK3
		{
			
		}
		if(sellArray == 3) //STK4
		{
			
		}
		
		
		return balance = balance + (stockSoldAmt*stockSoldPrice);
		
	}
	
	public String toString()
	{
		String output = "Valued customer " + name + " owns " + s1 + " ";
		
		// add to output - get s1.toString() on this for stock info
		
		return output;
	}
}

public class Stock {

	private String sname;
	private double sprice;
	private int svolume;
	
	public Stock()// constructor
	{
		sprice = 0;
		svolume = 0;
	}
	
	public void setprice(double p)
	{
		sprice = p;
	}
	public void setvolume(int v)
	{
		svolume = v;
	}
	public void setname(String s)
	{
		sname = s;
	}
	
	public String toString()
	{
		String out = " " + sname + " is priced at $" + sprice + " per share and it contains " + svolume + " shares.";
		
		// add to out
		
		return out;
	}

}

And the driver...

import javax.swing.JFrame;
import javax.swing.JOptionPane;



public class broker {


	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		Stock Stock1 = new Stock(); // this is a stock in the market (not with a customer)
		
		Stock1.setname("STK1");
		Stock1.setprice(8);
		Stock1.setvolume(10000);
		
		Stock Stock2 = new Stock(); // this is a stock in the market (not with a customer)
		
		Stock2.setname("STK2");
		Stock2.setprice(5);
		Stock2.setvolume(20000);
		
		Stock Stock3 = new Stock(); // this is a stock in the market (not with a customer)
		
		Stock3.setname("STK3");
		Stock3.setprice(9);
		Stock3.setvolume(10000);
		
		Stock Stock4 = new Stock(); // this is a stock in the market (not with a customer)
		
		Stock4.setname("STK4");
		Stock4.setprice(10);
		Stock4.setvolume(30000);
		
		System.out.println(Stock1.toString()); 
		System.out.println(Stock2.toString());
		System.out.println(Stock3.toString());
		System.out.println(Stock4.toString()); // output stock info
		
		Customer customer1 = new Customer("C1", 100000.00);
		
		System.out.println(customer1.toString());
		
		Customer customer2 = new Customer("C2", 25000.00);
		
		System.out.println(customer2.toString());
		
		Customer customer3 = new Customer("C3", 50000.00);
		
		System.out.println(customer3.toString());

		//Option window here...
		
	    Object[] options = { "C1", "C2", "C3", "Exit" };
	    
	    JFrame f = new JFrame();
	    f.setSize(250,250);
	    f.setLocation(300, 200);
	    f.setVisible(false);
		
		int x = JOptionPane.showOptionDialog(f, "Which customer are you?", "Stock Broker", JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null, options, options[3]);
		
			if(x == 0) //C1
			{
				
			}
			if(x == 1) //C2
			{
				
			}
			if(x == 2) //C3
			{
				
			}
			if(x == 3) //exit application
			{
				
			}
		
	}
