Stock Program - Stop User From Entering In Textfield And Display Message When Stock Is Low
Jun 29, 2014
I'm trying to make a stock program that stops the user from entering in textfield and displays a message when stock is low. There's just 2 problem the entered value by the user is only decremented twice then the total stock resets for example with SofaTotal and the if statement doesn't work:
I am trying to write a small program that will calculate the gain and/or loss of the sale of stock. The program will ask the user for the number of shares, the purchase price and the selling price. I am pretty sure that the errors is coming from my calculations in the program.
import java.util.Scanner; public class investmentCalculator { public static void main (String[] args) { Scanner input = new Scanner(System.in); //User input for number of shares System.out.print("Enter the number of shares: "); double shares = input.nextDouble();
i am writing a program that would be used for ticket sales and their are 100 tickets and a person can only buy 4 at a time. i need my program to not go negative at the end and also i need to stop the user from entering a negative number.
import java.util.Scanner; public class ticketmaster { public static void main(String[] args) { // Variable decoration uses strings , doubles and final doubles. Scanner in = new Scanner(System.in);

how many integers the user wants to use. The user will enter for example a 4. The user inputs a 2, 4, 6, and 10. So then we get our outputs...Then the code will ask if you want to run this program again. My question is, if the user inputs a -1 for example 2, 4, 6, -1....the code will not continue. I wanted to use a while loop, such as while (scores != -1) but it doesn't work.
Enter the amount of integers you want to use4 Intenger # 1 2 Intenger # 2 4 Intenger # 3 6 Intenger # 4 10 You entered 2.0 4.0 6.0 10.0 Average = 5.5 Variance = 8.75 Standard Deviation = 2.96 Do you have another set of numbers?
I'm making a stock system for the heck of it,so everything was going great until I hit the loop I am trying to use a for loop to add stock to the stock system,any way the question is maily about loops.How come I cannot declare a variable outside a loop and assign a value to it,for example I can declare as follows and I will not get an error,
but in my code(and yes its the only error I get I tested it) I get an error and can only declare and assign a value inside the loop,the reason for this is because I wanted to get the value from another class and use it in the loop ok so heres the code from both classes.
public class mainn{
public static void main(String [] args){ stock first = new stock(); int internal; internal = first.wanted;
I am doing a multi threading program . I am unable to get the output i want. I have no compilation error . But I cant get the result I , Null exception. This is my Test program
import java.util.*; public class Test { public static void main (String[]args){ int totalShares = 0 ; double totalCost = 0.0; String name = "FCS"; double profit = 0.0;
I have a Stock Database query class, it compiles and runs well. Thing is when i enter a user, it shows a user stock information but it repeats showing the same user in the command prompt. the repetition is so fast, you can't see the information. All i wanted was the application to show a user's info, then asks you to enter another user again and so forth. Here is the code
import java.io.*; import java.sql.*; import java.util.*; public class StockDatabaseQuery { public static void main(String[] args)throws Exception { String userID; String firstName;
[URL] I made a program that takes 2 stock values by URL tickers, and now I need it to draw a graph with the values for the 2 stocks, so they can be compared visually. So far my idea was to create 2 arraylists that consist of the values for each stock, so that I can draw the graph so that x always move with 1 step, and y0 is the first coordinate, and y1 is the second, and after that y1 is the first, y2 second etc.
I have Stock Tracker application running, everything works just fine, but when i hit the List Users button, i get an SQL Exception which says "Column bot found". I tried searching for the exception from the internet, but the answers didn't suit my needs. below is the Stock Tracker DB i think the exception might be coming from.
public class StockTrackerDB { private Connection con = null;
// Constructor: makes database connection public StockTrackerDB() throws ClassNotFoundException,SQLException
As a part-time student, you took two courses last term. Write a Java program that calculates and displays your grade point average (GPA) for the term. Your program should prompt the user to enter the grade and credit hours for each course. This information should then be displayed with the lowest grade first, and the GPA for the term should be calculated and displayed. A warning message should be printed if the GPA is less 2.0 and a congratulatory message if the GPA is 3.5 or above.
I have a java program which would display a message dialog box. The problem is it would stopped working before even displaying the message dialog box. This is my code.
import javax.swing.JOptionPane; public class HelloDialog { public static void main(String [] args) { JOptionPane.showMessageDialog(null, "Hello World!"); } }
There is a pop-up window which would say "Java(TM) Platform SE binary has stopped working." I am using textpad. What should I do with this?
I am a first-timer using J2EE and here on coderanch.com and wanted to make a Simple Email-like System which a Registered User can Send Message/Email to another Registered User. how to do it. I have already my register/login process done but I'm stuck on how to make the Email. And I have an sample Bootstrap for my UserInterface which I want to use.
I am trying to write a program that asks the user to enter a number from 1 through 10 and then the program will display the roman numeral for that number.
I am also adding a error message in which i haven't yet because im still trying to figure out how to the program will do the roman numeral.'
I have used the if and else if. but when i input a number it just repeats the number back to me.
The program cimpiles but it doesn't do what i want. here is what i have so far. how can i get the program to display the roman numeral after the number is entered.
import javax.swing.JOptionPane; public class Romannumeral { public static void main(String[] args) { double number;
I am working on this rental program and got stuck in the last part. The program is about renting a car; after completing the rent process it displays the user who spent maximum and minimum rent. This is where I can't proceed. The program displays maximum values for both max and min. Here's the code I have written:
import java.util.Scanner; // program uses Scanner public class CarRentalTest { public static void main( String[] args ) { System.out.println("Welcome to Rental Portal"); Scanner input = new Scanner( System.in ); // create Scanner to obtain input from command window CarRental details=new CarRental();
in my ui i will i will select enabled or disabled then it will go in controller , i already debug it and it goes on the right controller based on what i select on ui my problem is when i select disabled it dont display the message but when i select enabled it displays the message, then i check the databases status is change based on what i select but when i change into disabled doesnt display any message.if select enabled will go in controller then change status into true then update the status then will see the message in ui
I need making the toString() method return a String rather than display a message to the screen. Also, I'm not supposed to call the toString method in my demo class to test it, so what should I do instead?
public class cupDispenser { String location; int noOfCups; cupDispenser(String location,int cups) { this.location=location; this.noOfCups=cups; } public String getlocation()
So it is the question: This program implements a simple "decoder ring". It will prompt the user for a message to decode and decode the message based on the following substitution rules:
ABCDEFGHIJKLMNOPQRSTUVWXYZ will map to ZEBRASCDFGHIJKLMNOPQTUVWXY
abcdefghijklmnopqrstuvwxyz will also map to ZEBRASCDFGHIJKLMNOPQTUVWXY
any other characters (like space, punctuation, will map to themselves)
so if it sees an 'A' (or an 'a'), it will map to 'Z', etc... All i could think of is this but can't figure out the rest.
import java.util.Scanner; public class DecoderRing { public static void main(String[] args) { String1[] = 'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'; String2[] = 'Z','E','B','R','A','S','C','D','F','G','H','I','J','K','L','M','N','O','P','Q','T','U','V','W','X','Y'; } }
Not sure, what things are necessary such as switch statements or if and else or for loops and such...
I made a guess a number program but I am having issue figuring out a way that when a user enter's in nothing for the program to spit out a message saying "hey entering nothing doesn't work try again" then ask for input. I have done some research and from what I have found is to read the input in as a String rather than int, and use something like Integer.valueOf() to get the integer value but I am completely lost on how to apply that to my program here is my code
//import statements import java.util.*; //for scanner class // class beginning public class Guess { public static void main(String[] args ) { //Declare variables area int guess, secretNumber = (int) (Math.random() * 10 + 1), lowGuess,highGuess;
I wrote stand alone program to post message to IBM MQ , not sure if it posted to queue i see these Another 2,102 character(s) omitted is that mean it didnt post complete message? do i have to increase capacity of text size
I am trying to make a program that takes the information from the main args, and displays them as a email in another class when Java is run.
Ex. From: PersonA To: PersonB Email message is here
I have gotten this far, but every time I append my "email.print()" into the next class, it never can print any of the Strings.
Main Args Class:
public class TestMessage { public static void main(String[] args) { Message email = new Message("Harry Morgan", "Rudolf Reindeer"); email.append("Dear so and so,"); email.append("It is my great pleasure to"); email.append("write you an email."); email.append("");
