Receive Input Events From A MIDI Interface Device
Sep 9, 2014
Using JVM under OSX 10.9.4?:
Receive input events from a MIDI interface device.
This has suddenly stopped working for me after years of using the Java MIDI software.
I have tested this on two different macbook pro's.
I have a variety of MIDI interfaces from different manufacturers. I can find the devices using MidiSystem.getMidiDevice. But I cannot get them to see any input MIDI events.
I can create events in code and send them to output devices and have them seen by those devices. It's just the input that seems to be broken.
I have tried using previously working software I having been developing for years and I have tried with a very simple test program.

I haven't been able to find a cut and paste working example of how to receive MIDI data from a MIDI device, like my piano, and display something to System.out.There are all sorts of examples for synthesizers, sequencers and sending data to a MIDI device, but I have not been able to find a single example of how to receive MIDI data and just display a simple message.
I just need something simple that works to start playing with it, and understanding how it works. Having a working example would also support understanding the Sound API descriptions. They read like differential equations texts books to me, i.e. not clear at all.
I have a working example of how to poll all devices and getDevice.info, which is supposed to then be used to address a specific MIDI device.
I've also looked at a number of books, in the store and on line.I haven't seen a single example anywhere.the closest I found to working examples was on StackOverflow, but I didn't understand some of the other code in the examples, which may or may not have been working correctly anyway.

I have just taken it upon myself to attempt to develop an application using java that will implement several features for my aircraft maintenance unit. I've taken a few courses in Java and I am a computer science major, so I wanted to use this as a way to improve my coding skills while also improving the effectiveness of my unit.
Anyway my application needs to have these key features:
1. Access a recall roster that is in Excel format and read the names/phone numbers of up to 200 members. The application also needs to be able to update this information and save it.
2. The application also needs to be able to initiate a recall to some or all of the members on the recall roster via text message.
3. The application needs to be able to receive messages back and display them under each name from the recall roster.
My current plan is to set up a GUI that expands JButtons in a scrollable window as members are read in from the excel document. Upon clicking any of the buttons the person will be contacted individually via a custom message that can be typed in via a popup window after clicking it. Alternatively you can check a box next to any persons button to add them to the list of people to be contacted and then click a button that says "Contact those checked" or something along those lines. Finally there will be a button that just says initiate total recall and it will contact everyone.
As for the interface I want each button to be highlighted red until a response has been received from the person associated with that button, which will then be recorded under their contact information.
I've attached an extremely rough picture...

The scenario:
* A pop-up menu generates an array of rectangle objects; each rectangle having random x.y coords and colour.
* The number of rectangles in the array is user selected from the popup list.
* The APopUp class has a 'getter' method that returns the array.
* The pop-up object is instantiated in an object of the AFrame class.
* The AFrame object needs to get the array each time the popup changes its state.
The problem:
.
* As I see it, the AFrame object needs to informed of the pop-up's state of change event or does the problem lie in how I have decided
which responsibilities each class is to have? I've tried to be as logical as possible during planning.
In the days of FORTRAN or BASIC we would hammer a solution through with brute force, but I would like to keep to Java's philosophy
of encapsulation and clean interfaces and that it seems to has generated a impasse of brain warping proportions.
import java.awt.Frame;
import java.awt.Label;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
public class AFrame extends Frame implements ItemListener {

I got my first project in which i need to receive some data from multiple client on network regularly(say every second) and then process that data and stored it to the database and then GUI needs to be created which display data accordingly.
While thinking for the design i thought blocking queue to implement the same. Like producer receive data from the port into a string builder and put that into the LinkedBlockingQueue. Consumer will take this data , process some work on it and store it into the database.I am using sybase ase 15 as a database.
My question is as i am receiving data very frequently which require insertion , updation and search almost every second into the database. What is the best way to improve the performance.
say i have 2 types of data is coming one having keyword 'Alarm' and other having 'ceased' so i need to use something like this
common fields in both is name and number.
if (ceased)
search into the database for particular event for which this ceased receive using name and numbe rand update the another field into it Also make separate entry for it
else
make a entry
Also as i am using 2-3 thread for consumers and thread = Number of client for the producer. So i thought to use synchronization at the consumer side which writes data into the database such that only 1 thread can write it.

I'm using the JOptionPane to display and receive information to/from the user. In addition to this, I am using StringBuilder to receive inputs from the user and then manipulate (append) that input to display the desired output.
//Example
(JOptionPane): "Enter text"
(user input): Java is cool!
(program): *stringBuilder.append(" I love it!")
JOptionPane.showMessageDialog( );
.....
Psuedo-like code. The problem is that showMessageDialog(null, string) and not showMessageDialog(string, string). I want to display the enter text: " Java is cool! I love it! " in the JOptionPane. How do I accomplish this, since showMessageDialog only accepts (null, string).

I wanted to write a simple code that receives information from the user (double-digit number and above) and calculates it's numbers.
For instance- The user wrote a number- 234, the software will return the number 9 (2+3+4 = 9).
Tried to use a loop for that, but I got stuck since I didn't know what to write.
This is what I've wrote so far
Java Code:
import java.util.Scanner;
public class Calculate {
public static void main(String[] args) {
System.out.println("Please type a number larger than 9");
Scanner type = new Scanner(System.in);
String number1 = type.nextLine();
for( int i = 0; i < number1.length(); i++ ){
int calculate = number1.charAt(i);
}
}
} mh_sh_highlight_all('java');

We were given the assignment to program a lotto game. in our game we should do follow the following steps below, and we are supposed to use atleast tree methods. the first one to receive the array of integers and an integer and check if the int was not entered before. the user should not repeat the same number. the other method will draw all numbers of a game (quantity of numbers to draw is based on the number parameter) and returns them in an array. the last method will display the result of the game. It receives a list of all lines played and a list of all numbers draw.
these are the steps to follow:
1. Ask the user how many lines (games) the user would like to play. Each line is made of five numbers between 1 and 45 (inclusive).
2. Ask the user to enter five numbers between 1 and 45 (inclusive) for each line. The user must NOT be allowed to enter a number more than once for each line.
3. When all the numbers for all the lines are entered, the program should display all lines and asks the user to confirm the game. If the user does NOT confirm the game, the program should start all over again.
4. Draw (generate) five numbers between 1 and 45 (inclusive). The numbers should be unique within the draw.
5. Draw (generate) one number (the bonus number) between 1 and 45 (inclusive). The number should be unique within the draw.
6. Display all the lines played and the result of each line.
7. Ask the user if the person would like to play again, if so the program should start the process all over again.

I have two questions:
1. I read somewhere that instead of looping through every player (below), you use could Events to do it for you:
for (Player player : this.getPlayers()) {
if (player.getLocation().getX() == 10) {
}
}
I'm not sure as to how to use Events in place of a for loop. I've been thinking on this for days, but I'm still stuck. Any example of using an Event instead of a for loop?
2. Is there any way to accept multiple connections on a server without using a while loop? Maybe use Events to handle the acceptance of connections?

I'm trying to create a Servlet that takes input from a form and process it and insert it in database.tablename.
My MAIN ISSUE IS WITH THE NUMBER OF COLUMNS THAT WOULD BE DYNAMIC AND THUS CANT RECEIVE THE PARAMETERS IN STATIC CODE.
Here is the form code
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<form action="Test" method="post" />
<table width="90%" border="1" cellspacing="1" cellpadding="1">
[Code] ....
And here is the Servlet
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
import java.io.*;
public class Test extends HttpServlet {
[Code] ....
This is the basic code structure and I'm trying to figure out this special case with handling the multiple parameters:
I don't want to use String []a=request.getParameterValues("studentname"); as hard code. The reason being the number of rows will be diyamic and I would like to get the column name and then then use an array of string to take values. But how can I connect these to form a query so that the rows goes on inserted one after other.

How do you test the events within an inner class using JUnit
// File: : events/SomePanel.java
// Purpose: Show use of named inner class listener.
import javax.swing.*;
import java.awt.event.*;
class SomePanel extends JPanel {
private JButton myGreetingButton = new JButton("Hello");
private JTextField myGreetingField = new JTextField(20);
[Code] .....
Code extract taken from: Java: Inner-class Listeners
Taking the above example, do I need to use myGreetingButton.doClick to trigger this event to test the respective variables/values being used ? Also the Actionlistener inner classes is private so doubt I can access this from JUnit Test class.

I'll try to catch gesture events (ZoomEvent, SwipeEvent, etc.) from fx controls (e.g., an ImageView) that are embedded in a JFXPanel. However, no gesture events are thrown for the embedded fx controls.
I've read How to integrate javaFX gesture management in a complex Swing application? and it seems that "there is no gesture recognition in a JFXPanel".
But I've also tried this code SwingHtmlDemo - Pastebin.com that embedds an fx WebEngine in a JFXPanel. In this example, I can Zoom and Swipe the google map displayed in the WebEngine.
My Questions are:
How does the gesture recognition in the WebEngine work?
Can I reuse the gesture recoginition of the WebEngine for other fx controls embedded in a JFXPanel?

I'm trying to synchronize two folders and their sub directories between a client and a server. I have a modified version of this class which I've posted below. In my Client class, I create a WatchDir object and call its processEvents() method in an infinite loop. The method returns a myTuple object (a struct containing the event type and a path object) if an event is registered and null if not.
The problem is that this only seems to work for the first event to happen in the directory (i.e. if I add a file to the watched folder, my WatchDir object.processEvents() returns one Tuple with an ENTRY_CREATE event and never returns another Tuple for other file additions/deletions/modifications that happen after). I'd like for processEvents to be continuously called (hence the infinite while) returning a Tuple each time some event occurs.
My modified WatchDir:
import static java.nio.file.StandardWatchEventKinds.*;
import static java.nio.file.LinkOption.*;
import java.nio.file.attribute.*;
import java.io.*;
import java.util.*;
import java.util.concurrent.TimeUnit;

Code structure :
Server : Java Servlet
Client : Simple JSP
Communication : Server Sent Events every 1 second
Here is the problem.
My code needed the server to send updates every one second to the client as stated above. Hence, I added a while loop with a sleep of 1000 milliseconds in the servlet code as shown below. The following strange behavior is observed:
- While the server is sending updates to the client, and the client window closes by mistake, the server does not stop sending updates It continues sending the data.
- When the client is re-opened, it sends data much faster (almost double). For example, the server sends 60 seconds worth of updates (60 updates) in just 25-30 seconds. The server sends faster updates not only for this round of updates, but also for any subsequent updates.
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse res)
throws IOException, ServletException {
PrintWriter writer = null;
try{
[Code]......
This server behavior is much unexpected. Am I writing the server side code wrong? I have looked around a lot and only found while loop method for modifying the server update interval. Is there any other method which I am missing?

Is there a possibility to use events for additional mouse buttons, like the next or previous mouse buttons, in javafx? If I use the setOnMousePressed event on a node, it only throws an event for the "PRIMARY" "SECONDARY" and "MIDDLE" buttons.
node.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override public void handle(MouseEvent mouseEvent) {
System.err.println("mouse button: " + mouseEvent.getButton());
}
});
If I use this java application [URL] .... it is also possible to throw events for the next or previous mouse buttons of the mouse. But not in my javafx application.
