Mastermind Game - Comparison Event
Jan 14, 2015
I'm not so new to java i know the basics. I want to make a mastermind game. Just for training purpose.
Now i am at the comparison phase where it is comparing your chosen "colors" with the actual "color code"
This is my code for that part:
guesChars is a char array of 4 of the actual code
readGuess is a string of 4 of which the players has filled in the console
goodGuess is a char at the right position with the right "color"
avgGues is a char with the right "color" at the wrong position
Java Code:
for(int i = 0; i < guessChars.length; i++){
for(int ii = 0; ii < readGuess.length(); ii++){
if(readGuess.charAt(ii) == guessChars[i]){
if(ii == i){
[Code] .....
The problem is when the code is for example
ACDD
and the player guess is
ADDD
Result is
2 right spot right color
1 right color wrong spot
It have to be
2 right spot right color
0 right color wrong spot

All I am trying to do is to make a section of code execute if two strings are equal. The two strings are userId and "A001062". When I use the debugger in Eclipse, I can see the value of userId as "A001062" but whatever string comparison I try never evaluates to true. I have tried
userId=="A001602"
userId.equals("A001602")
"A001602.equals(userId)
Assigning A001062 to a string called AAA and comparing userId to AAA
My code is as follows. I have also attached a screen shot from the Eclipse Debugger which makes me think the string comparison should succeed. I never see the debugger execute the print line nor do I see the print line on the JBOSS console.
String userId = StringUtils.trim(nextLine[HR_USER_ID]);
String AAA="A001062";
if (userId.intern().equals(AAA.intern())) {System.out.print("MKP1: " + userId+"-"+managerId);}
if (userId.compareTo("DTS0428")==0) {System.out.print("MKP2: " + userId+"-"+managerId);}

I would like to create a component to detect the file being modify before process.is it the right way to detect the file modification based on file size value?
Below are the flow:
1. Get the file size of a file
2. Used file size value encrypt it with MD5 algorithm, and say it generated us encrypted value "0123sdf"
3. to avoid user modify the file content, before file process, we take the file and do the encryption with md5 again, if it return value "0123sdf", then we are sure it doesn't have modification.
my question:
a. is it the right approach to detect file modification?
b. what the library advise to use or using java.security.DigestInputStream will do?

So - working on some new document composition tasks today, and realised my life would be made easier if I could have an application to allow me to compare two documents and highlight the differences...I know I could use a number of other tools, even word compare but it would be more fun if I could do it myself. Plus - there's the thrill of using non-approved technology at my workplace...I'm a maverick.
Just looking for the high level steps I should go through in creating an application which could be delivered to users in my team as an executable file (I have admin rights to my works laptop, but my direct reports do not have this on theirs) so would need to be able to run the app without installing if possible...

I got a task from my teacher and the restriction is we are not able to modify this class (and that is the problem).This is the given class:
public class Jobs {
private intcounter= 0;
private final intnoElements= 20;
private final int[]a= { 11, 28, 31, 42, 49, 66, 67, 75, 89, 100, 102, 103, 114, 125, 130, 135, 140, 145, 150, 155 };
private final int[]s= { 20, 9, 7, 6, 12, 15, 4, 7, 30, 22, 11, 45, 20, 6, 6, 5, 5, 5, 5, 5 };
[code]...
I need to compare some of the values of the given arrays. For example: if(a[4]<a[2])... etc.
How can I do these kind of operations to a private array? I have to compare the values in an new classPS: I have to compare the values in a new class

I am trying to match validate user input via regex comparison. But i fail to do so.
The string that will be inserted will have the following pattern: "digit/s " and it can be repeated a random number of times.
The program will extend to characters in the future but for now i am struggling with digits.
i am using a StringBuilder to build the regex string. Or maybe i could use something else but so far i didn't make it.
So far i have this regex
Java Code: "(d+s+)+" mh_sh_highlight_all('java');
The problem is that the newline character will interfere with the last number.
So if i enter
Java Code: "3 4 555" mh_sh_highlight_all('java');
- it will not match. And the regex will only see 3 4.
But if i enter
Java Code: "3 4 555 " mh_sh_highlight_all('java');
- with an extra space at the end it works. Obviously that is not the desired case.
I did find a workaround, but i fear it is somewhat broken
I changed to
Java Code: "(d+s*)+" mh_sh_highlight_all('java');
But in this case the pattern should see 3 4 5 5 5 as the regular expression. Am i correct?
I also tried some other variants but none of them worked:
Java Code: "d+(s+|*)" mh_sh_highlight_all('java');
Or i could do something like
Java Code: "(d+s){" + i + "}" mh_sh_highlight_all('java');
- where i is the number of values i enter.
Am i on the right track here? What am i forgetting?

I want to compare two times. What I am doing is
java.util.Date date = new java.util.Date();
java.sql.Time cur_time = new java.sql.Time(date.getTime());
/*this is my database connectivity code from where I am getting second date that I am comparing. This is right. Don't bother it.
Connection c= ConnectionManager.getConnection();
String sql = "select t from datesheet where subjectCode=? and sessional=? and d=?";
PreparedStatement ps = c.prepareStatement(sql);
ps.setString(1,subjectCode);
ps.setString(2,sessional);
ps.setDate(3,cur_date);
ResultSet rs = ps.executeQuery();*/
if(rs.next())
{
java.sql.Time t = rs.getTime("t");
long diff = cur_time.getTime()-t.getTime();
}
Then I am converting it to seconds, minutes and hours, but the problem is time that we get from cur_time.getTime() has more digits than time that we get from t.getTime(), so it is always greater than t.getTime() even when it is not.
long seconds = (diff/1000)%60;
long minutes = (diff/60000)%60;
long hours = (diff/(60*60*1000))%24;

Opoly works this way: The board is a circular track of variable length (the user determines the length when the game app runs). There is only one player, who begins the game at position 0.
Thus, if the board length is 20, then the board locations start at position 0 and end at position 19. The player starts with a reward of 100, and the goal of the game is to reach or exceed reward value 1000. When this reward value is reached or exceeded, the game is over. When the game ends, your program should report the number of turns the player has taken, and the final reward amount attained.
In Opoly the game piece advances via a spinner - a device that takes on one of the values 1, 2, 3, 4, 5 at random, with each of the five spin values equally likely.
Although the board is circular, you should draw the state of the board as a single "line", using an 'o' to represent the current player position, and * represent all other positions. Thus if the board size is 10, then this board drawing:
**o******
means that the player is at location 2 on the board.
Here are the other Opoly game rules:
If your board piece lands on a board cell that is evenly divisible by 7, your reward doubles.
If you land on the final board cell, you must go back 3 spaces. Thus if the board size is 20, the last position is position 19, and if you land there, you should go back to position 16. (If the position of the last cell is evenly divisible by 7, no extra points are added, but if the new piece location, 3 places back, IS evenly divisible by 7, then extra points ARE added).
If you make it all the way around the board, you get 100 points. Note that if you land exactly on location 0, you first receive 100 extra points (for making it all the around), and then your score is doubled, since 0 is evenly divisible by 7,
Every tenth move (that is, every tenth spin of the spinner, move numbers 10,20,30,... etc.), reduces the reward by 50 points. This penalty is applied up front, as soon as the 10th or 20th or 30th move is made, even if other actions at that instant also apply. Notice that with this rule it's possible for the reward amount to become negative.
Here is the driver class for the game:
import java.util.*;
public class OpolyDriver{
public static void main(String[] args){
System.out.println("Enter an int > 3 - the size of the board");
Scanner s = new Scanner(System.in);
int boardSize = s.nextInt();
[Code] ....
heres the methods:
REQUIRED CODE STRUCTURE: Your Opoly class must include the following methods (in addition to the Opoly constructor) and must implement the method calls as specified:
playGame - The top-level method that controls the game. No return value, no parameters. Must call drawBoard, displayReport, spinAndMove, isGameOver.
spinAndMove - spins the spinner and then advances the piece according to the rules of the game. No return value, no parameters. Must call spin and move.
spin - generates an integer value from 1 to 5 at random- all equally likely. Returns an integer, no parameters.
move - advances the piece according to the rules of the game. No return value, takes an integer parameter that is a value from 1 to 5.
isGameOver - checks if game termination condition has been met. Returns true if game is over, false otherwise. No parameters.
drawBoard - draws the board using *'s and an o to mark the current board position. Following each board display you should also report the current reward. No return value, no parameters.
displayReport - reports the end of the game, and gives the number of rounds of play, and the final reward. No return value, no parameters.

Im trying to make a tic tac toe game that you play against the computer using a random number generator and two dimensional arrays for the game board. Im not trying to make a GUI, the assignment is to have the board in the console, which I have done. I have run into a few problems with trying to get the computer player to correctly generate 2 integers and have those two integers be a place on the game board. Here is my code so far.
import java.util.Random;
import java.util.Scanner;
public class TicTacToe {
private static Scanner keyboard = new Scanner(System.in);
private static char[][] board = new char[3][3];
public static int row, col;

How the event Listeners work in java,To get the data based on the event occurs in outside the application. I have this method in one of my API class I am not understanding how this methods are going to work.
public interface SBXPCXMLEventListener {
public void OnReceiveEventXML(String eventXML);
}
private static List<SBXPCXMLEventListener> listenerList = new ArrayList<SBXPCXMLEventListener>();
protected static void fireXMLEvent(String xml) {
[Code] ....
I have done like this.This is used to capture the events from the fingerprint machine when run this class I am not getting any data from the machine when i did thumb impression in the machine.
public class EventListnere implements SBXPCXMLEventListener {
public static void main(String[] args) {
boolean flag = SBXPCProxy.ConnectTcpip(1, "10.0.0.8", 5005, 1234);
System.out.println("flag = " + flag);

java.awt.Component is an abstract class, and it's direct Sub-classes are Button, Canvas, Checkbox, Choice, Container, Label, List, Scrollbar, Text Component
So, when I use addXListener(mylistenerclass m);//which is a method of Component class which object is holding the list of all listeners, for a particular Event Source?
I am under the assumption that - there is an Event Source Object(possibly static) for every Event Source type(mouse, keyboard etc) that holds a list of destinations(classes that implements their listener interface) - added to the the object via addXListener method. When an event happens(mouse click, drag etc) the Event Source Object creates an Event Object and send it to all the destinations. Is my assumption correct? I can't seem to find the location or declaration of Event Source Object and the list where it stores it's registered destinations.

How would you begin a program that schedules events? I've found codes that are similar like Calendars, but I need something that will still import the real day, month, year. But I want to have columns that show Room numbers, and rows that shows time slots. How to get started such as which GUI components to use, what packages to import, etc.?

I used java and jsf. I created dynamic datatable in java file. Can i call java method from setOnchange() event?
I am able to call java script function from setOnchange() event. See the below code which is working fine for java script.
HtmlSelectOneMenu selectOneMenu = new HtmlSelectOneMenu();
selectOneMenu.setStyleClass("dropdownStyleTwo");
selectOneMenu.setOnchange("openWin(this);IGNORE_UN LOAD=false");
I wrote openwin() function in java script. But i am not able to call java method change().
Code which is not working.
HtmlSelectOneMenu selectOneMenu = new HtmlSelectOneMenu();
selectOneMenu.setStyleClass("dropdownStyleTwo");
selectOneMenu.setOnchange("myclass.change();IGNORE _UNLOAD=false");
myclass is the bean of class Test. If user select any value from dropdown i want to call change java method. This function will apply the same selected dropdown value to the other record also.

regionsBuilder.setMultiChoiceItems(
displayNames, regionsEnabled,
new DialogInterface.OnMultiChoiceClickListener()
{
@Override
[code]...
Questions:
1. Describe what the code displays. A error message would be shown when the use has selected an insufficient number of options.
2. Describe when an event handler (included in the code) gets executed? The event handler gets executed every time a user selects an option(???)
3. Explain a feature of what is displayed
4. Explain the meaning of all of the parameters in the central, complicated call of the code.
5. Describe how the code handles two possible situations.When the user has selected a sufficient number of options (no less than or equal to 0), then no error message would be shown. On the other hand, an error message will be shown when the user has not selected a sufficient number of options (0). (???)

I have one requirement where when i click on the attribute i would like to create an action and display the same in OutputText.
Ex:
This is Attribute Description outputText :
<rich:columnGroup id="CMAttributeBrowserDescriptionRow2">
<rich:column id="CMAttributeBrowserDescriptionColumn2" styleClass="selectedObj"
rendered="#{CMBrowserBean.attributePresent}" >
<!--<h:outputText id="SelectedObjectDescription1" render="true" value="#{currentAttribute.value}"/>-->
[b][quote]<h:outputText styleClass="attributeTableFont1" readonly="false" id="attributeTextdescription" disabled="false"/>[/quote][/b]
</rich:column>
</rich:columnGroup>
The action should be for :
<rich:column id="AttributeColumn2" styleClass="parentBrowserColumn">
[b]<a onclick="document.getElementById('CMBrowser:0:CMAttributeBrowserDescriptionForm:attributeTextdescription').value=#{currentAttribute.name}" >[/b]<h:outputText id="AttributeName" title="#{currentAttribute.name}" value="#{currentAttribute.name}"
styleClass="attributeValueFont" /></a>
</rich:column>
I am unable to get the text coming on outputText, when i click on the above attribute.

You're given a number between 0 and 1 that corresponds to the probability of an event occurring.
0.7 is 70%, 0.235 is 23.5%, 0 is 0%, etc.
Someone tries to perform the event, but the event only has the given probability of occurring. Run the probability, and then if it's true, run the event. Otherwise don't run the event.
All I know how to do is generate random numbers (kind of), but if you have 0.2245 I really don't see how generating random numbers can efficiently perform that probability.....
