Display What The Computer Chose (GUI Boxes)
Nov 29, 2014
for my class we have to make a rock paper scissors game using GUI boxes. Everything is working fine I'm just having trouble displaying what the computer chose. In other words, after the user selects Rock, paper or scissors, the scoreboard just pops up displaying the score. Here's the last working program before I started tinkering with it.
// your code goes here
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.Icon;

In vb.Net, when I do the code msgbox("hello world") and put it in a loop, it will execute that command and show a new messagebox for every time the code goes through the loop. I am wanting to do something similar with java but I'm afraid I don't know how.I know that the following code will display a messagebox as I am describing it
Java Code:
JOptionPane.showMessageDialog(null, "message", "title", 1); mh_sh_highlight_all('java');
But when put in a loop, it does two things:
1) It hangs the program
2) It will only display the first message box and when you press ok, the other message boxes will be disregarded and not displayed (I'm assuming because of the hang).

For some reason the two JOptionPane message boxes at the end of my code don't seem to open when I run the program.
package assg2.kevin;

import java.util.Random;

I am able to generate text boxes. But I need one specific thing in that:
Through a drop-down I should select a number and those many text boxes should get generated.
Suppose I selected 4 from the drop down list. Then on screen it should display:
Student 1: Textbox
Student2: Textbox
Student3: Textbox
Student4: Textbox

I want to get current Computer CPU usage of my computer and display it in Console View of Eclipse? How can I achieve this?
My template code is:
Java Code: public class GetCPUUsage{
public static void main(String[] args){
System.out.println("CPU USAGE IS: ??????");
}
} mh_sh_highlight_all('java');
I added ??? as placeholder for CPU usage because I do not know how to retrieve RAM usage by Java.

I have to write an example program to fill boxes most efficiently with bags. All bags are the same size. The boxes come in Large, Medium and Small. Large boxes hold 20 bags. Medium boxes hold 10 bags. Small boxes hold 5 bags. I am getting input from JOptionPane input dialog box and then parsing that input to an integer.
I have to fill the large and medium boxes completely. I am not sure how to do this without an if statement. I can use one, but we have not covered it in class, so I am skeptical about using one to solve the problem. If I just divide the input number with integer division, I'm not going to get the remainder, right? So I'm thinking that I can mod my input number by 20 (the number of bags the user inputs) and then mod that number by 10 and then mod that number by 5, would that work?

From what I can determine check boxes are applied in SWT to the first column only of a table.
final Table table_project = new Table(g3_tabfolder_projects, SWT.BORDER | SWT.CHECK);
However I require check boxes on all cells. I tried creating a table for each column (which gives me my check boxes) but as the number of enries are often numerous and thus require vertical scroll the tables become out of sync (and to the user that sync is important).
Before I knock up some code to try and synchronise the tables I just wanted to check any alternative approaches. The project is SWT based.

My application (e.g., the print dialog box) needs to support multiple languages (user selected either at starting application or by switch in code).
How can this be achieved under Windows 7, Enterprise (works OK under Linux). I have tried : E.g.,
Locale.setDefault( .. );
JComponent.setDefaultLocale(Locale.LANG);
Setting resource bundle
but to no avail. The application always inherit the Win 7 system locale.

I am creating a set of 3 subclasses, 1 superclass, and an application. In my instructions it says to make set methods in my super and subclass by using dialog boxes. In the application you have 3 different arrays where you create objects and are supposed to call the methods from the subclasses to be used in the application. I don't know how to make the dialog boxes from my subclasses to show up in my application.

I wrote a Chess game that uses socket to connect to another computer, and allow player vs player and player vs computer game sessions.
However, there is a problem which I noticed.
When you get the IP address of the computer in which the program is running, you are not getting the computer's actual IP, you are getting the Router's IP.
Is there a way to get around this.
So the problem is that when I go to another computer, located in a different house or lets say from my school, the program cannot connect back to my home IP, because it uses the router's ip, not the computer's ip I am running the server program.
Is there a way to get the Computer's IP, not the router's ip when summoning or invoking the get IP address method from the socket class?
When I say that the socket class is acquiring the router's ip, well that's done without my interfering...I don't know why it does that, it is somehow recognizing the router and not the computer.
The thing is that the server program is written that any client program is able to connect to the home server.
But when I run the program from a different location other than the current home, the sockets don't connect because it is somehow recognizing the router's ip not the computer's ip.

I understand the basics of using the JOptionPane Message boxes, but how do i take the information that is entered and store it as a file, or print it. I'm in my 6th week of class, and this happens to be maintenance related.
import javax.swing.JOptionPane;
public class Example_Maintenance_System{
public static void main (String [] args) {
//Operator Name Input
String operator_name;
operator_name = JOptionPane.showInputDialog("Please scan your barcode");

I am working on a project in which I have three box (as of now) and each box will have some color of balls. So I am storing them in a Map of String and List of String as mention below.
Map<String, List<String>> boxBallMap = new LinkedHashMap<String, List<String>>();
Data in the above map is like this -
Java Code:
{box1=[blue, red, orange]}
{box2=[blue, red]}
{box3=[blue, red, orange]} mh_sh_highlight_all('java'); ProblemStatement:-
Basis on the above input, I need to return a mapping which will be List<Map<String, String>>, let's say for above input, below mapping would be return as an output -
Java Code:
[{box1=blue, box2=red, box3=orange},
{box1=red, box3=blue},
{box1=orange, box2=blue, box3=red}] mh_sh_highlight_all('java');
Here if you see, each row has alternate color of balls for each box - meaning blue for box1, red for box2, orange for box3 in first row. I cannot have same color of balls in each row. So this combination is not possible as it has same color of balls for two boxes in one row.
Java Code: {box1=blue, box2=blue, box3=orange} mh_sh_highlight_all('java');
And also, in the second row, I won't use those balls which have been used in the first row for that box. In second row, box1 has red why? bcoz blue was already used in the first row for box1 and box3 has blue and no box2 in second row.
The output combination is getting generated basis on the input being passed as shown above.
I started with the below code -
Java Code:
List<String> balls1 = Arrays.asList("red", "blue", "orange");
List<String> balls2 = Arrays.asList("red", "blue");
List<String> balls3 = Arrays.asList("red", "blue", "orange");
Map<String, List<String>> maps = new LinkedHashMap<String, List<String>>();
[Code] ....
Below is my method in which the crux of logic should be there
Java Code:
private static List<Map<String, String>> generateMappings(Map<String, List<String>> map) {
return null;
} mh_sh_highlight_all('java');
Below algorithm might work but still not sure how should I fit this in the code -
- sort the boxes by the number of balls they have in it (ascending, from the smallest to the largest box).
- while there are colors left
- loop over the sorted list of boxes
- in each iteration pick a color from the box (if there is one left), that is not already picked in the current iteration (of the while loop)

I know there are Java graphics classes, and how to use them to draw images in a window, but how do those classes interact with the screen to create the image? At the very base of it all, what is the code that is passing the computer the data to display on its screen? I'm asking because I've seen several ways to do Graphics/GUIS, a lot of them involve the Graphics class, but what is it inside all of that that that makes it work? Also, is everything else involving graphics (any other graphics libraries people write) pretty much "on top" of the Graphics class or is there something else within it more basic that is being used?

I'm supposed to write a computer based testing program using files. I have started writing however, I am stuck. I am to prompt the user to enter the file name 'test.dat" and if something different is entered then a error message should be displayed. Also the file will create an input stream for the data using the file. I am to have the user enter other information about an employee and then write the record to the file.
The program should be created so when the user enters "quit" the loop is terminated and the file is closed. I'm not asking for code. I was just giving a brief synopsis of the project. Where I am stuck is I wrote the first part of the program that creates the file; however when I enter a wrong file name the exception error message does not display. The code is below:
import java.io.*;
import java.lang.*;
import java.util.*;
public class Project5Write
{
private Formatter x;
public void openFile(){

I need to activate the setting 'Keep temporary files on my computer' (Java control panel/general/settings) on about 150 Windows 7 PCs in a Samba3-Environment (which does not have GPOs). We are running Java Version 8 Update 45 (build 1.8.0_45-b14) on all of the PCs. Is there a way to change this setting with the command line, a registry entry or somehow else?

I have separated characters into an array that can be accessed from any method, however, when I try to compare the inputed guess to the computers random sequence, the counter always comes back as 0 (the comparison occurs in the checkColour method).
Java Code:
package mastermind;
import java.util.Scanner;
/**
* Program Description: play a game of mastermind versus the computer
*/
public class Mastermind {
private static int block1, block2, block3;
private static String blockColour1, blockColour2, blockColour3;
[Code] ....
The counter is called colourCorrect.. But I think the problem lies more in me converting the strings (input and computerGuess) into char arrays, as if I output the values at position in the array, I get numbers (but the numbers are not character values from the ascii table).

I have a beginning Java Program I have been working on that creates a number guessing program where the computer guesses a number that the user is thinking of within a certain range. I so far have the program below, but need getting rid of a few kinks/ adding features.
-First, I need to set it up so that the user will be prompted and give a range. It should run and produce something like this:
Welcome to this first-ever mind-guessing program!
Please pick a range (higher than 1 and no larger than 50): 32
You will choose a number between 1 and 32... and I will try to guess it.
With each of my guess, you will tell me whether I am too high (h or H), too low (l or L), match (m or M), or you want to quit (q or Q). My objective is to find the number using as few guesses as possible.
-Second, the game is supposed to give up and restart after failing the five, guesses, but for some reason, after it fails the fifth time, it prompts a fifth guess once again instead, then restarts after- I need to prevent this, so that it should look something like this:
My fourth guess is 17: h
My guess is too high?
My fifth guess is 16: h
*** I am unlucky this round. I give up.
Let's play!
My first guess is 10:
etc..
import java.util.*;
import java.lang.Math;
public class numguessprac1 {
// Declaring variables
public static String input;
public static int quit;
public static int guess;
public static int wins;

Write a class named FileDisplay with the following methods:
1.) constructor: the class's constructor should take the name of a fil as an arugment.
2.) displayHead: This method should display only the first five lines of the file's contents
Here is the following code I have made so far
import java.io.*;
public class FileDisplay
{
private String filename;
public FileDisplay(String Filename) throws IOException
[Code] ....
First, in my constructor I have taken in an argument and used that argument to open up an output file. Meanwhile, I'm trying to work n the displayhead method to print out information and to read data to. I haven't opened up my input file yet, but I'm not understand how can I read a print data to an output file. in
public void displayHead()
{FileWriter file=new FileWriter(Filename)}
do I make create another instance of the filewriter class to output data?
In simple words, suppose to I want to display some messages on my output file in the displayhead function. Since I already have opened up the file in the constructor, how do I combine that in this method...
