Thanks, it works.

I have the following switch statement and I need to end the program if the user select number 2.
switch (choice) { case 1: System.out.println("Good choice"); break; case 2: System.out.println("this choice end the program"); break; }
When the user select the number 2, the program still runing, but it needs to terminate.

Joe,
I�m doing my work, I just don�t know and I have to ask, it is part of the learning process. I�m sorry if I insulted your in a previous posting. Let�s get something done and don�t sweat the small stuff.

This is what I have so far:
/* This program will help to host a Hallowing Party.*/ public class PartyXXX { String userName; public void wellcome() { System.out.println("Welcome to the halloween party planner."); System.out.println("Are you brave enough to come to the party????"); System.out.println("Answer y for yes o or n for no."); char answerLetter; answerLetter = SavitchIn.readLineNonwhiteChar(); if (answerLetter == 'y') System.out.println("Good choice, You are brave!!!"); System.out.println("Please enter your name: "); userName = SavitchIn.readLine(); System.out.println(" "); if (answerLetter == 'n') System.out.println("You are a coward!!!!!"); String junk; junk = SavitchIn.readLine(); int count, number; System.out.print(userName + " Please enter your age: "); number = SavitchIn.readLineInt(); count =1; if (number < 21) System.out.println(userName + " You are not allow to drink alcohol"); if (number < 16) System.out.println("You must be accompanied by an adult"); System.out.println(userName + " Your are allowed to drink if you are not driving"); } public void information() { System.out.println("The party will be held at 1600 Pennsylvania Avenue, D.C."); System.out.println("at midnight on 31 Oct. 2003"); System.out.println(userName + "You must use a custom in order to enter the party."); System.out.println("Drinks and snacks will be provided"); } public void wine() { /*public static void output() {*/ double dBottlesUsed; double dCostPerBottle; double dCostOfWine; String stWineName; System.out.println(" "); System.out.println("This program will calculate the cost for wine "); System.out.println("for your halloween party.

Here is the main method:

And here is the error message for PartyXXX:
C:\cs151\Week 7\PartyXXX.java:193: cannot resolve symbol symbol : variable array location: class PartyXXX array.output(); ^ 1 error Tool completed with exit code 1
Can you help to solve this error?

Joe,
That's an excellent idea, I will ask the instructor, thanks. You are really smart.

Joe,
Thanks for taking the time and review my program. I tried each code individually and they work, but when I put it together I got the error messages. So, I already used the programming technique that you referred. Any way, if you don't know how to fix it, probably somebody with experience in programming will help.

This is what I have so far to completed the following assigment:
The program should include a menu of options using a switch statement, a for statement, three or more methods, an array, a loop, an if statement and instance variable and methods.
Design the program to call methods kept in the PartyXXX file form the main method. One method could tell something about the party such as where it's located, what time it will be and what the party goers need to bring. Another could calculate the cost for supplies, food, drinks, etc.
I got the following errors:

Hello friends,
I got the task to create a program to assist in hosting of a halloween party. The program must call methods kept in the PartyXXX file from the main method PartyXXXStart. One method must serve to display the party location, time and what to bring, another method could calculate the cost for the party and who will be invited, and other method could be a list of the most popular customs. The program must included a switch statement, a for statement, three or more methods, an array, a loop, an if statement and instance variables and methods.
If you have already created a similar program that could be adjusted or if you have any idea that you want to share, please let me know.
Here is what I have so far, first the error messages:

The instruction for the homework are as follow:
The instruction for the homework are as follow:
"Write a program using an array that prints out the counting numbers form 1 through 60 that can be divided evenly by 4. The program should print out the numbers from left to right on your DOS screen wiht no more thatn 4 numbers on a line and at least three spaces between numbers. Also print out the number of numbers and the sum of all these numbers that can be evenly divided by 3."
