There must be a simple way to just have java play an mp3 file.
View Replies View RelatedJavaFX 2.0 :: Create Button Bar The Same As Confirmation Dialog
May 1, 2015I want to create a button bar that is the same as the confirmation dialog button bar -- so an OK and cancel button layed out in the platform specific way, and with the same styling.
I have made some progress via a hack -- create an alert dialog, and extract the buttons in the dialog using lookupButton, and then put those buttons in a toolbar. But this doesn't necessarily get a toolbar with the buttons in the correct order. If I could get the button bar out of an alert dialog I would have a solution, but I can't see to do that.
When Click On New Button / All Icons Except Button Just Clicked Don't Display
Oct 16, 2014The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.

View Replies View RelatedGoing Through All The Keys On Keyboard One At A Time
Jul 14, 2014I am writing a code that tries to figure out the users password by going through every possible key (brute force). Although I think its going to work, it looks EXTREMELY inefficient to me, since its just a huge switch statement for each character -- 94 total, including the shift values. Is there a built in method in the JAVA API that goes through every key or something?
Here is my code for that segment:
public char[] HackingPassword(){
char[] passChars = this.password.toCharArray();//convert the password to char[]
char[] hacking = new char[passChars.length];//make the hacking variable same size as users password
int nextCharValue = 0;//this is used to cycle through the keyboard
//check each letter of hacking to match with password
for(int i = 0; i < passChars.length; i++){

Reading The Name Of The File From The Keyboard
Feb 20, 2014Write a program that extracts words from a file. For the purposes of this program, a word is defined as a series of adjacent letters. Only print words that are at least four and no more than 12 letters long. Print each word on a different line.
The program should read the name of the file from the keyboard.

I need to get the filename from the user for this particular program. Usually I would have the name of the file prewritten into the source code like this....
Scanner input = new Scanner(new File("gettsy_burg.txt");
I tried different ways but I just can't seem to figure it out.... I guess what I'm really asking is how to rearrange Scanner input = new Scanner(new File("gettsy_burg.txt"); since I want the user to input the filename instead of the filename being prewritten by the programmer(me).
This is what I have so far to let the user for input....
Scanner keys = new Scanner(System.in);
System.out.println("Enter the filename: ");
String fileName = keys.nextLine();
keys = new Scanner(new File(fileName));

How To Avoid Keyboard Auto-repeat
Oct 8, 2014I wanted to make a small program to move a small rectangle by pressing the WASD keys. The program works, except that when I hold a key to move the rectangle, after a second, auto-repeat starts up, and the rectangle motion accelerates. I want to prevent automatic repeat to activate, so that the rectangle moves at a constant speed when I hold a key and stops when I released. Here is the ButtonMotion classe :

right now the client that the user download uses the keyadapter to get the keyboard input, but whenever the user un-focus the chat window, the keyadapter no longer gets the keyboard input.so is there another way i can get the keyboard input? so it doesn't matter what window you are focused on, you get the keyboard input either way?

The parameter for the starting y is "fy" (Half of the screen). When I use the keys "z" and "x" it translates one pixel at a time left and right. That is good, but when I use the keys "a" and "s" it will double each time (good), but the starting y will drop significantly (bad). I tried manipulating the "x" and "fy" variables, but to no avail.

View Replies View RelatedSwing Button That Creates A New Button
Nov 29, 2014I am creating a mad libs type program. This section of code is for the user to be able to make their own mad lib template (that people will be able to fill out later). The normal blanks in a mad lib are for verb, noun, adjective, adverb, etc. I cam up with 13 or so of these buttons, but it would be nice that if the user wants to add a button that they think we missed, such as 'Person in the Room' or 'Silly Location'...that the user would be able to do this. I sort of pictured there being a button that says 'add button' or something like that. Is there a ways to do this with the way I've set things up?
