Check For Win In Tic Tac Toe
Nov 25, 2014
I am having trouble figuring out how to check for win in tic tac toe, the way my teacher wants it is with various if statements but im not sure what to put in the parentheses. I think it would be something like
if(button==button.getIcon(x)) {
if(button2==button2.getIcon(x)) {
if(button3==button3.getIcon(x)) {
playerWon=true;
player2Won=false;
}
}
}
This is what i have so far
import java.awt.Container;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TicTacToe extends JFrame implements ActionListener
[Code] .....

This SHOULD be a simple program, the gist of it is Given an element E and the array A that represents a set X (user input), write a program that determines whetherE is an element of X.I have the array list all set up to take the user input and make zero the last element of the array. I want user to input numbers into array, then have fixed numbers for E and check to see if E is in the Array. I guess I'm not sure how to check the array and see if E is in the array? Here is what I have so far...
import java.util.ArrayList;
import java.util.Scanner;
import java.util.List;
import java.util.InputMismatchException;
public class Set {
public static void main(String[] args) {
List<Integer> userInputArray = new ArrayList<Integer>();
[code]...

I am having an issue with my swing gui. I dynamically create tabs with information (textfields, checkboxes, combo boxes) and when I select the checkbox it disables or enables a textfield. Now when I select the checkbox it seems to resize everything, specifically my textfields from say 9 columns to probably one. I"m a little unsure why it is doing this but I have a feeling it may be an inheritence issue.
My code is below for my generation of the tabs and of the rest of the information on the gui. The gui is an inner rid layout with a top and bottom pane that are both gridbaglayouts and an outter pane as well. I am thinking I am missing something in the grid layout setup that is causing this.
private void initComponents() {
jTabbedPane1 = new javax.swing.JTabbedPane();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
getContentPane().setLayout(new java.awt.GridLayout(1, 0));
pack();

1. In jsp 1 , i have 3 checkboxes(chkbox1,chkbox2,chkbox3) , if i select check boxes (chkbox1, chkbox2), and click on submit, corresponding two text fields (chkbox1,chkbox2) will have to appear in the next jsp i.e., jsp 2.

Like this, which ever checkbox i select, corresponding text fields should appear in the subsequent jsp.

I'm trying to come up with a method that would validate each turn a player makes. For a turn to be valid, it has to only contain numbers from 0 to 3(inclusive) and at least one digit must not be 0. Here is what I`ve come up with so far. For example, with "303" as the number and "101" as the turn, the turn would be valid and my method should return true, but it does not.
public static boolean turnIsValid (String number, String turn ){
boolean rep=false;
int pos1=0;
char min='0';
char max='3';
while(number.length()==turn.length()&&pos1<turn.length()){

What I'm trying to do is say if the array contains the character a, then output: this letter is already in the array. I tried
if(arrayList.contains(a)) {
System.out.println("This is already in the array!");
}
but it's not working. What should I use?

I am currently trying to write a method for checking to see if an "agent" in a cell (place in a 2d array) is satisfied. So, the assignment is a 2D array that can have a blank space, an O, or a X as a character that fills a particular space. An agent is satisfied if it has similar characters around it in a percentage that is higher than the threshold. For example, if the threshold was 60% and a cell that had an X in it, had 3 X's around it and 2 O's, then it would be satisfied because 3/5>=60%. For my code, I tried using if and else statements to isolate circumstances in the corner of the grid, the edges, and everything in between.
public static boolean isSatisfied(char[][] tissue, int row, int col, int threshold){
char check= tissue[row][col];
if (check==' '){
return true;
}
else{
int countx = 0;
int count = 0;

I am using form based, declarative security approach. And, when some user, on login form enters user credentials (username and password), he is being redirected to certain/secured jsp page.
Part of that page content is:Hello <%=request.getUserPrincipal().getName().toString()%> You are able to view this page because you are authorized user.You can see that this is implemented using JSP scriptlet. And this works. I would like to use JSTL instead of scriptlet.
So, instead of scriptlet, I put this JSTL code: <c:out value="${requestScope.userPrincipal.name}"/>, but not getting user's username with it. Basically, I don't clearly understand where and how are these objects/user credentials being stored with Form based JAAS.
I would like on JSP page to check if some user is already logged in. So, if there is logged user to display user's name (also with JSTL).Something like this:
<c:if test="${not empty sessionScope.userPrincipal}">
User <c:out value="${sessionScope.userPrincipal.name}" />
</c:if>
Here I tried with sessionScope but still not getting anything.

My program here asks for an unit to choose from (fl.oz, gal, oz, lb, in, ft, or mi), asks how much of it they have, and asks for the unit they wish to convert to (mL, l, g, kg, mm, cm, m, or km).
My program works, refusing to convert from silly conversions such as gal to cm, telling you to re-input if they enter anything other than fl.oz, gal, etc.
The only thing I cannot figure out is if the user inputs something like "foo" when the program prompts the user for how much of the unit they have. My goal is to have the program say something like "That is not a number! Please enter a numerical value."
My current dilemma right now is that if the user inputs something other than a number, it will catch the exception and print a line telling the user it's not a number, except, it does it infinitely (stuck in a loop). Here is my code:
import java.util.InputMismatchException;
import java.util.Scanner;
public class UnitConversions {
public static void main(String[] args) {
Scanner s = new Scanner(System.in);
double result = 0;

I was wondering if there was a way to check/view messages from my phone. I'm trying to create a program that will be able either read messages from my phone, or reply to them. I'm trying to get this to work for a Window Phone, but I don't know if there is a difference between doing it on a Windows Phone or Android. Most of the topics that somewhat relate to what I'm doing are all Android based.
I've looked at AT Commands, SMS Gateways, but I'm still not sure if it's entirely possible.

I have a program that allows the user to select what type (i.e. tif, jpg, sid) of file they have to load. I use a JCombo box for the selection type. I send this JCombo box string to my ElevationConvert class. What I want to do is check to see if that extension the user selected exists prior to converting it. If the file extension does not exist, I want to pop up a window (JOptionPane) stating is does not exit. I have tried suggestions found on this site, but does not seem to work for my application. The program works with (Process cN = Runtime), if I try not to check for the extension. But when I add the check for (If, else), it bombs. This executable runs in the main folder. The file extensions are in a subfolder called Ned.

I have to ask how many children's tickets you want to order. When I apply the code below, it just accepts whatever I input, including letters. I imagine it is to do with setting childrensTickets = 0? If I input a letter using the below it accepts - shouldn't it print the error given the input is not >=0?
System.out.print("How many children's tickets do you require? ");
int childrensTickets = 0;
boolean validChildrenValue = false;
while (validChildrenValue == false) {

I tried to make a program that takes a string str, and char a and checks how many times the char is used in the string.
Example: the string Welcome and the letter e, is 2 times. so the program should print 2.
It compiles but when I run it and enter the information, i cannot get the printing line out.
Heres my code:
import java.util.Scanner;
class program
{
public static void main(String[] args) {
Scanner user_input=new Scanner(System.in);
String str;
String b;
System.out.print("Please enter a word");

I have an assignment and one of the prompts is to do a binary search on an array if and only if the array of Strings is sorted. The binary search part I think I have completed, but it is the sorted array check that is throwing everything off. If the array is already sorted, return true; else, return false.
// Check if the array is sorted
public static boolean isSorted(String[] arr) {
//for (int i = 0; i < arr.length-1; i++)
//{
//if (arr[i].compareTo(arr[i+1]) > 0)
//return false;
//}
String[] arrSorted = arr;
Arrays.sort(arrSorted);

I have a number of objects stored in an ArrayList called inventory. Let's say I have two objects inside.
inventory.add(new Lamborghini(2011, "aventador", 411.3, false));
inventory.add(new Lamborghini(2012, "sesto elemento", 512.3, true));
I am making a function to search through the whole inventory to see if any of the Lamborghini object has a certain model name such as aventador, diablo, etc....
This is what I have but I figured there's a big mistake when I make it true / false; it's making it going through the list and what's return is the last one instead of saying there's such match in the whole list or not.
public boolean hasCarModel(String modelName){
boolean exist = false;
for (Lamborghini lambo : inventory){
String carModelName = lambo.getModelName();
if(carModelName.equalsIgnoreCase(modelName)){
[Code] ....
I figured if I add break; under exist = true; it'll work because as soon as it found one match then it'll turn to true and break out the loop but I don't think this is the best way to do it right?
