How do i generate a random letters?

for my end of the year project i need to create a program that is essentially a guessing game... it randomly generates 3 seperate letters, and i have to guess them, how do i do this? the generation part
plz someone help me out, i really need this credit....email me or hotmail me @

thanks so much guys

What I'd do is generate 3 random numbers between 1-26, then corrispond those to letters. ASCII would be the easiest way.

How can you generate a random number?

Say I have a timer, and I need it to choose a random number between 100 and 1000. How would I do that?
timer.delay(***RANDOM***);Thanks!

I have this, and it's working for me:
int j = rand.nextInt(500);
But I actually want it to generate a random number between 100 and 500, not 0 and 500. How could I do this?

How do I generate a random String

Hi, there is probably a very simple answer to this question, but nevertheless....
Is there a class I can use which will allow me to generate a random String of any length?
Many thanks.

depending on which chars you want to use for the String, sometimes it is more handy to use a char[], something like
publc static final char[] CASE_SENSITIVE_ALPHNUM = {'a', ...., 'A',....'1',...};//for alphamumeric case sensitive chars
public static final char[] CASE_INSENSITIVE_ALPH = {"a", ....,'z'};
public String randString(int length, char[] charset) {
StringBuffer sBuf = new StringBuffer();
for (int i = 0; i < length; i++ ) {
sBuf.append(charset[(int)(Math.random() * charset.length)] )
return sBuf.toString();

How can you generate Multiple random numbers from 1 to 49?

I am very new at programming with the iPhone SDK and I need some help with a project I am working on. What I want to do is set up a window with 6 labels and 1 button. When the user clicks the button, the program will populate 6 randomized numbers each ranging from 1 to 49, and then place each of 6 numbers in a label. But each time the program ends and starts again the numbers cannot be the same, and also when the user clicks the button, no label can have the same number twice, so for example. If label 1 had the number 10, the other 5 labels cannot have that number until the button is clicked again. I know how to set up the interface, I just need the code. I would so greatly appreciate someone's help in this matter. I have been trying to do this for days and I cannot figure it out. Possibly someone who knows tons about Objective C programming can help me!
Thank-you so very much!!

I see that you're writing a lottery number generator. Perhaps the easiest way to do it is to emulate a real lottery: fill an array (NSMutableArray, probably) with the numbers between 1 and 49, pick one at random, remove that number from the array, and repeat. (You can think of the numbers as being the balls and the array as being the machine that pops them out.)
One simple way to get the random indices needed is to extract six random bytes from Randomization Services using SecRandomCopyBytes, then loop over them, using the modulo operator (%) to select an index within the size of the array.
And no, I'm not going to write your code for you. If I was going to do that, I could package and sell the app myself.

How do you generate multiple random numbers between 1 and 49

I am new at mac programming and I want to make an iPhone app with the free SDK. What I would like to try is a random number generator. I imagine it as when the user clicks a button 6 random numbers from 1 to 49 would appear in a label or another control. If someone could please give me the code that would place these randomized numbers in a label I would greatly appreciate it. I know how to link all the controls together, I just need the code. Thank-you to anyone that can help!

semi-sudo code goes here
--prepare and array which will have number from 0 to 49
--loop thru the array like this
int i=0
for (i; i<=49; i++) {
int a=arc4random() % 49] ;
int b=arc4random() % 49];
--here exchange the objects so that they are shuffled
[myArray exchangeObjectAtIndex:a withObjectAtIndex:b];

How do I generate a random color? Here's my code...

I'm trying to color a rectangle one of four colors, randomly. I can't figure out what I'm doing wrong. Here's my code:
import javax.swing.*;
import java.awt.*;
public class Rectangle extends JComponent {
     private static final long serialVersionUID = 1L;
     public Rectangle(int x, int y, int w, int h) {
        super();
          setBounds(x, y, w, h);
        setBackground(Color.RED);
    public void paint(Graphics g) {
        g.setColor( getBackground() );
        g.fillRect(0, 0, getWidth()-1, getHeight()-1);
        repaint();
        paintChildren(g);
}Basically, I need "g.setColor( getBackground() );" to be one of four random colors. I have a seperate class that this is used for.
Here is some code I was throwing around, but it doesn't seem to work at all:
public void randomcolor(int too) {
     Random ran = new Random();
     too=ran.nextInt(4)+1;
     switch (too)     {
     case 1: color=Color.blue;
     break;
     case 2: color= Color.green;
     break;
     case 3:color=Color.orange;
     break;
     case 4: color=Color.green;
     break;
     default: System.out.println("wrong number, pick another ");
     top.setBackground(color);
     left.setBackground(color);
     right.setBackground(color);
     bottom.setBackground(color);
}     Any help would be amazing. Thanks!

Thanks! Your code worked exactly as it was supposed
to. =D
Unfortunately, mine's kind of messed up at the core.
You see, I have 4 rectangles (forming a square) that
flash in a random position at a random size in a
window (like a screen saver.)
Each time the square flashes, I need it to be a
different color, preferably with all the sides the
same random color. However, where I put the random
code, it chose random colors for each side and stuck
with them throughout the whole animation of the
square bouncing around.
I'm not sure what to do, now. If you want, I'll post
my code, if you think you can help.
~DacWhat you could do then is move the responsibility of changing the Color of a Rectangle away from the Rectangle class and let one class control the four Rectangles. Something like this:
import java.awt.Color;
import java.util.Random;
public class RectangleController {
    private static Random rand = new Random();
    private Color[] colors = {Color.blue, Color.green, Color.orange, Color.green};
    private Rectangle[] rectangles;
    public RectangleController() {
        rectangles = new Rectangle[4];
    public void changeColors() {
        Color newColor = getRandomColor();
        for(Rectangle rect : rectangles) {
            rect.setBackground(newColor);
    private Color getRandomColor() {
        return colors[rand.nextInt(colors.length)];
}

Generate a random number

How do you generate a random number?

You can also check out Math.random() which returns a
double value between [0..1)You could, depending on your needs, but if you do want ints then you're better off using nextInt from java.util.Random, as outlined by the author here:
http://java.sun.com/docs/books/effective/excursion-random.html
(and what was wrong with 125?! I thought that was a perfectly fine random number...)

I am unable to control my iPad 2. It is generating random letters when typing and when I try to delete it generates more letters unless I go slowly! Any advice?

I am unable to control my iPad 2. When typing and deleting it generates random letters! Any advice

Start with this and see how it goes. Quit all apps completely and reboot the iPad.
Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

How to generate pseudo random noise(PRN) binary sequence using shift registers?

what is the block diagram to generate pseudo random noise (PRN) binary sequence of 1's and 0's using shift registers
please help
i need 2 submit this project in this week

This is a fairly simple homework problem. My hints (on the LabVIEW side):
1- look at while loops
2- look at shift registers on while loops with multiple input elements
3-look at the logic components, AND, OR XOR
Look at this wiki article: http://en.wikipedia.org/wiki/Linear_feedback_shift_register
Do the work, you won't learn if someone shows you how it is done! The palette that the previous post points to are of PRN and other "noise generators" but I suspect that is not what you are after.
Know that creating a PRN with a reasonable number of shift register taps produces very pseudo results, as the "random" pattern begins to repeat pretty quickly, thereby making it not a truly random number.
When you have an attempt that is sort of working and want additional suggestions, post the code here. We won't do your work, we will help you try to do it, and learn it, yourself.

How to generate n random dates between 2 time periods

Hi,
I'm trying to write a method that generates n random dates between 2
time periods. For example, lets say I want to generate n random dates
between Jan 1 2003 and Jan 15 2003. I'm not sure how to go about
doing the random date generation. Can someone provide some direction
on how to do this?
The method signature should look like this.
public String[] generateRandomDates(String date1,String date2,int n){
// date1 and date2 come in the format of mmddyyyyhh24miss.
// n is the number of random dates to generate.
return dateArray;
Thanks.
Peter

first take a look at the API concerning a source of randomness (Random might be a good guess), then take a look at stuff concerning dates (Date might be cool, maybe you will find some links from there).

Urgent How to generate a random code such as registration code?

I would like to ask that how to generate a random code?
For example, when you register a E-mail account, you need to enter the code for activation. I would like to create a java Bean to do this job. Would you help me?

In fact, I would like to set a 10 digi codes randomly (such as FH654CS081, MKO624VG9f) for user input when they register the forum account. This random code will be sent to the user's email. User have to input this code to a JSP web site. Also, the code which is inputed by user will be matched with the database. If user input success, the forum account will be activated.
By generating this 10 digi codes, I want to handle this generation by using java bean.
1) Any thing else i need to import ? (such as <% page import="java.......?")
2) Any functions can handle this task?
3) Any example can be my reference?
Thank you very much

How to generate unique random numbers

Hi All,
I am wondering whether there is already a random library or built-in function available in Java to produce some random numbers between certain ranges that are not repetitive. Let's look at a common examples as follows:
Random diceRoller = new Random();
for (int i = 0; i < 10; i++) {
int roll = diceRoller.nextInt(6) + 1;
System.out.println(roll);
}My understanding from this approach is that it allows the same number to be repeated over and over again. However, I would like to find out how to continue generating random numbers from remaining ones that haven't been generated earlier.
Using the above example to illustrate my intention:
1st random number generated - possibility of 1 - 6 showed up. Say 5 is picked.
2nd random number generated - possibility of 1, 2, 3, 4, 6 only. Say 2 is picked.
3rd random number generated - possibility of 1, 3, 4, 6 available. Say 1 is picked.
4th random number generated - possibility of 3, 4, 6 left. Say 6 is picked.
5th random number generated - possibility of 3, 4 remains. Say 4 is picked.
Any assistance would be much appreciated.
Many thanks,
Jack

How do you generate random data info using json and spry?

I have a mobile applicaton that uses spry datasets that dynamically populate a jquery mobile listview by using a json file. Everything is operating as it should.
However, I would like to understand how to pull random objects from the json file to have them displayed on a different page.
My json file is standard and not complicated. It has several levels. Each is represented as below:
                              { "Level1":
                                                            {"imageurl":"images/_myimage.png",
                                                            "someData":"S,A,P,R",
                                                            "levelLongDesc":"further description",
                                                            "name": "John Doe",
                                                            "page": "referencepage",
                                                            "description":"The description of the image"
{"imageurl":"images/_myimage.png",
"someData":"S,A,P,R",
"levelLongDesc":"further description",
"name": "John Doe",
"page": "referencepage",
"description":"The description of the image"
Json file Level1 has about 70 objects
What I would like to do is randomly load one of the Level1 object arrays into the page when the user selects a Level 1 radio button that is on the screen. I know how to create the page, radio buttons and basics, but just don't know how to pull in the random data.
I've found one code sample on this site that speaks to spry and xml, but I haven't been able to apply it in any way that works for me with the json file:
http://forums.adobe.com/message/662551
I've also googled. There isn't much on spry datasets with json and generating random info. There was a little bit on sorting, but that didn't help either.
Does anyone have a good example/tutorial of how to use the random function with spry/json?
TIA
-Rachel

I've done similar things before. A few thoughts for you:
1. I'm assuming you're doing a buffered period or frequency measurement on the incoming encoder pulses, right? First key point is that you'll have data that is spaced equally in position, but not equally in time. If you are looking for a time-based FFT such that increasing speed will shift your spectrum, you're going to need to go through an interpolation process to resample your data as though equally-spaced in in time.
2. Your 149 pulse per rev encoder may be a significant source of error unless its 149 pulses are placed with extreme accuracy. Any error in pulse placement violates your underlying assumption of data that is equally-spaced in position. It'll be very helpful to send your data through a software lowpass filter to attenuate those artifacts.
3. I am not sure what you mean by "decompose the buffered data (array) into a single datastream." You'll get an array of periods / frequencies from the call to DAQmx Read. If you want to use it in a LabVIEW waveform datatype, you'll first need to do the resampling to create equally-spaced-in-time data. The LabVIEW waveform datatype (and all the analysis functions like FFT that use it) depend on receiving data with a fixed constant time interval between samples.

How to generate a random session variable in php

i want to generate a random session variable and insert the variable in a mysql record to use later to validate an account set up.
person fills out form to create account and submits; inserts form information in mysql record.
i want the random variable to be inserted from a hidden field and the page sends an email with a link to click on to compare the variable to validate the user.
Not sure how to generate a random session variable and get that to the hidden field value to be inserted with the other form information.
thanks for your help,
Jim Balthrop

To insert the key I would personally do something like...
$key = md5($username . $password . $salt);
Insert that into your MySQL database, then send them a email with it, my next code shows how to activate it.
This is to activate the account.
<?php
$key;
$errors = array();
if(isset($_GET['key']){
     $key = $_GET['key'];
     $sql = 'SELECT * FROM users WHERE key = \'' . $key '\' LIMIT 1';
     $result = mysql_query($sql) or die(mysql_error());
     if(mysql_num_rows($result)){
          $sql2 = 'UPDATE users SET active = 1 WHERE key = \'' . $key '\' LIMIT 1';
          $result2 = mysql_query($sql2) or die(mysql_error());
          if($result2){
               //successfully activated account
          else{
               //Something Went Wrong!
     else{
          $errors[] = 'Invaild Key, Please try again!';
else{
     $errors[] = 'Invaild Key, Please try again!';
?>
