JavaFX 2.0 :: Set Default Stylesheet For User Control

Jan 26, 2015

How can I set the default stylesheet for a user control that I have created? I want to make the control available for anyone to use and I want it to use a stylesheet by default without the user of the control having to do anything. I also want it to be possible for the user of the control to override the definitions set on the default stylesheet if he wants to.

Asking User For Input Twice?

Apr 19, 2014

I'm working on creating a dice game and getting the users input is giving me a really hard time. I have the main game working but this part I'm stuck on. The problem is that it's not giving me the chance to enter the second input when I ask for the game.

//Create Scanner object
Scanner keys = new Scanner(System.in);
//Get chips

[Code]....

*****This is what I get when I run it

run:

How much money would you like to change? 50

You now have $50 in chips.

What game do you want to play? You did not pick dice.

Formatting User Input

Feb 4, 2014

I have been given a piece of work to do for College that requires me to format user input. For example: This is an example of text that will have straight left and right margins after formatting

will transform into:

This..is..an.example
of..text..that..will
have..straight..left
and...right..margins
after.....formatting

The user inputs the width, in the case above being 20. Each line has to therefore be 20 characters long. All spaces are to be replaced with full stops.

This.is.an.example.o
f.text.that.will.hav
e.straight.left.and.
right.margins.after.
formatting..........
public class Main {
public static void main ( String args[])

Value Will Multiply By User Input

Apr 14, 2014

I would like to multiply the amount stated inside program by user input. I currently have

public static void setTicket(double ticket)
{
//if statement for tickets
if (ticket == 1)
Ticket = 10.00;
else if (ticket == 2)
Ticket = 20.00;
else if ( ticket == 3)
Ticket = 30.00;

The user should enter 2 and the value should show 20.00. This does work however im looking for a way to say enter 2 = 2*10 instead of stating each value individually.

How To Save User Input

I have a program that asks you for your password and if it is incorrect it reduces your attempts until you are at zero, but I want to be able to tell the user what passwords they have attempted when they run out of attempts. I've tried a couple of things but how to get it to work. This is my code:

If Statements And User Input

Dec 12, 2014

I am new to java and I am trying to write a program where someone has to guess the number. The correct number is 3. If they are below three. It tells them that they are too low and to guess again. If they are too high, it tells them they are too high and to guess again.

However, I am having problems once they enter a number and they get the response "The number was too low. Try again" as it lets them try again but doesn't tell them if it's right, wrong, or too high. I'm not sure what piece of code I am missing. Here is what I have so far:

import java.util.Scanner;
public class Guessthenumber {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter a number between 1-10.");
double value = input.nextDouble();
if(value == 3)

Validating User Input

Oct 16, 2014

My project is a program that uses methods to display strings in a variety of different ways. I already have all of that working, my problem is checking for user inputs.For example on the menu portion of my program i ONLY want the user to input 1-5.here is the method i developed for checking user input IT DOES CONTAIN ERRORS this is where i am having troubles.

public static int checkInput(String prompt, int lowerBound, int upperBound) {
int input = 0;
boolean done = false;
while ( !done )
{
System.out.println(prompt);
if (input.hasNextInt())

[code]....

here is the rest of my program which is working fine besides the checking input. i would like to implement this method for checking inputs into all places where the user is asked to input something.

import java.util.Scanner;
public class DisplayingStrings {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int getNum = checkInput("Enter #(1-5)", 1, 5);
System.out.println("--String Writer--");
System.out.print("Enter a string: ");
String word = input.next();
displayMenu(word);

Evaluating User Input For String Or Int

Jan 14, 2015

I have to take a users input. The general gist of the problem is I want to convert a decimal number entered by the user inputs into it's binary equivalent....the conversion part I know how to do.

I'm stuck at the user input phase. If the user inputs a decimal number within the correct range (lets say between 0-5000 for this example) the conversion goes ahead as planned and the program outputs on the screen the binary equivalent.

If on the other hand the user inputs a number outside of this range ... OR a String OR and empty space, an error message is given and the user is asked to try again. I don't know how to handle it if the user enters the different types...int or String.
