I need to find the Winner using Object Orientation logic I have my old logic from my Tic Tac Toe game but it is not Object Orientated. So I want to convert it and add that code to my GUI Tic Tac Toe. I need to return a winner or tie.
View RepliesI'm trying to fix this logic error in my slot machine game where no matter what slot combo comes up, it says you have won $10 and proceeds to add that amount to the balance and subtract the bet amount to the balance, even though it is not a winning combo! I've been trying to solve that and when doing so, I commented out Slot1.randNum1 == 0, Slot2.randNum2 ==0, and Slot3.randNum3 ==0 and anything relating to see if that was the problem, and it seemed like it was, because after that, the logic error described above was gone, but in doing so, the loss/win counter didn't increment, nor did the program pick up on the winning combos. However, I do not know why commenting out anything relating to randNum ==0 would cause that.
Here is the code for the processing (as you can see, some parts are commented in attempt to fix the logic error, but right now the code below is for the logic error that keeps on telling that the user has won):
public void askData ()
{
title ();
int betAmount;
while (true)
{
try
{
c.setCursor (3, 1);

I want to run a few things in my main when a JButton is pressed but can't work out the best way to do it. Here's the code in the main.
public static void main(String[] args) throws FileNotFoundException, ParseException, InterruptedException{
Map m = new Map("defaultMap");
GameLogic g = new GameLogic("defaultMap");
GodsEyeView gev = new GodsEyeView(g, m);
gev.initialRun();
//Want to run this when a button is pressed.
HumanUser h = new HumanUser(g);
playerGUI gui = new playerGUI(h);
gui.run();
gev.run();

How do i take input values for TwoDPoint (which are objects) and return it back in numerical values also print them.
When i create an object in main method and pass values to my function of return type TwoDPoint,it gives error:- found int,int need TwoDPoiint,TwoDPoint.
// Here is what i tried to do:
Created class TwoDPoint that contains two fields x, y which are of type int. Defined another class TestTwoDPoint, where a main method is defined.In the main method created two TwoDPoint objects.
Then I modified the class TestTwoDPoint and add another function to it. This function takes two TwoDPoints as input and returns the TwoDPoint that is farthest from the point (0,0).
Then I added another function to TestTwoDPoint. This function takes two TwoDPoints as input and returns a new TwoDPoint whose x value is the sum of x values of the input TwoDPoint's and whose y value is the sum of the y values of the input TwoDPoint's.
class TwoDPoint {
int x = 2;
int y = 4;
}
class TestTwoDPoint {
public static void main(String args[]) {
TwoDPoint obj1 = new TwoDPoint();
System.out.println(obj1.x);
System.out.println(obj1.y);

Create an equals method that takes an object reference and returns true if the given object equals this object.
Hint: You'll need 'instanceof' and cast to a (Geocache)
So far I have:
public boolean equals(Object O){
if(O instanceof Geocache){
Geocache j=(Geocache) O;
if (this.equals(j)) //I know this is wrong... but I can't figure it out
return true;
}
else return false;
}
I think I have it correct up to the casting but I don't understand what I'm suppose to do with the this.equals(). Also I'm getting an error that I'm not returning a boolean... I get this all the time in other problems. I don't get why since I have to instances of returning booleans in this. "returns true if the given object equals this object" makes no sense to me. I assume the given object, in my case, is 'O'. What is 'this' object referring to?
I wish to print the content of a JTextArea. I know I can do this with textarea.print(). However, I wish to print in a different font, font size and orientation from that of the JTextArea itself. I have been able to change the orientation by setting print attributes
PrintRequestAttributeSet printAttributes =
new javax.print.attribute.HashPrintRequestAttributeSet ();
printAttributes.add(javax.print.attribute.standard .OrientationRequested.LANDSCAPE);
And then using the textarea.print() method that allows me to set attributes. However, I haven't found any way to set the font and font size.
I get a Base64Encoded image string (GIF format) from an external system. While reading the byte array and saving the image to file, the image gets saved in landscape orientation. The code snippet is below.
String image = "R0lGODdhCAcgA=";
Base64Coder decoder = new Base64Coder();
byte [] decodeBytes = decoder.decode(image.getBytes());
ByteArrayInputStream stream = new ByteArrayInputStream(pngArray);
BufferedImage bImage = ImageIO.read(stream);
File label = new File("C:/labels/test.gif");
ImageIO.write(bImage, "gif", label);
I want to save the image in portrait orientation. Is there a way to do that?
I need to return all the object name of one class in an array. I have a class named country, and other classes with athletes and medals etc. I need to do a method that list an array with all the countries that participate, so all the objects created with the class country (i.e canada.country, usa.country, etc). Is there a way I can retrieve them?

I don't know how to define "abs." Here are the instructions:
The purpose of this exercise is to add to the IntClass class below a method, abs, that takes as its only argument an IntClass object and returns a new IntClass object representing the absolute value of the argument.
Define the desired method as a class method.
Define the desired method as an instance method.
In each case, use the main method to test your code.
There's two boxes of editable code. I'm having trouble with the first one, the one with "abs."
Here is more code:

Here's another box of code that they want me to fill out:

How to start and structure my program because i am fairly new to the program but want to try to make a game. My idea of the game is it generates random numbers between 1-100 for two people and the program compares the two random numbers and declares the player with the higher value the winner like the card game war. Then it would give you an option to try again.
View Replies View RelatedI want to use a method, which takes for example an int and also returns an integer. For example, if the the given integer is strong return a, if it is notstrong return b. How would you write that in a Code?
I want to use that in a more general way. I want to give a method mlong the value X of the type date and let it return an int. Type date consists of 3 int, one of them is the int month.
mlong should return an int depending on the X.moth. at the moment my code looks like this:
// File1:
public class date {
public int day;
public int month;
public int year;
}
// File 2:
public class monthlength {
public int mlong(date X) {
int t;
t = X.month;
if (t == 1 || t == 3 || t == 5 || t == 7 || t == 8 || t == 10 || t == 12)
{ return 31; }
if(t == 4 || t == 6 || t == 9 || t == 11)
{return 30;}
}

I want to generate a new tile every 1,5,10,15 (please check the code to gain an understanding of where I'm going) the session last for 4m :20 sec, I need using the date package, I tried using the sleep method however I don't want to pause the whole thread, so I need setting up the time aspect of the key generation (assume all other code works).

I've been assigned to create a Black Jack game with a gui. In this game I've created a seperate Player and Dealer class, and both initiated them, however when I try to call a Player object in a certain way I get a null pointer reference. (It should be noted that the Player object is an array)
public void runGame(){
while(running){
while(dealer.getPoints() <=19){
int count=0;
[Code] .....
And this is how I've initilized the Player class in the constructor
Player[] players = new Player[numberofplayers];
for(int i=0; i<numberofplayers; i++){
players[i] = new Player(i);
players[i].setDeck(d1);
gui.add(players[i].getPanel());
}
What I don't get is if I change players[i] to dealer, it works fine.
The program i am working on is to take string from the user which should be a phone number then it will return true or false based upon the method that checks to see if it meets the criteria of a certain format if does not it will return false otherwise return true. I am working on a if/else structure that will print this number is valid if it meets the criteria of the method i previously mentioned or return the number is not valid if it is false. the logic of the expression i put in the parentheses of the if/else statement. This is what i have so far:
if(){
System.out.println("The phone number is valid");
}
else {
System.out.println("This isn't a valid phone number");
}
Do i need to compare it based upon the method that checks if it is true?

I've decided to go back to basics and start using pseudocode--but i want to see if my logic is correct.so here's the first program:each delegate to a certain conference must wear a tag showing their name and the organization they represent as shown below:
######################
#### Annual Conference #####
######################
##NAME: ##
######################
##ORGANIZATION: ##
######################
write a class called TagMaker that prints out tags. supply methods to (a) set the name (b) set the organization (c) print tag with the name and organization (d) clear the name and organization (e) print a blank tag. then write a TagTester class to test the TagMaker class. so this is the pseudo code (or logic) that i've come up with for the program:
TagMaker main class:
-Prompt user to enter in first and last name, as well as their organization.
-Read user input for the name and organization.
-Return user input.
-Write conference tag showing the person's information.
-Clear information.
-Print blank tag.
1. i assume i would have to import a few java libraries.
Java Code: java.util.Scanner mh_sh_highlight_all('java'); and Java Code: java.io.*; mh_sh_highlight_all('java');
2. afterwards i would declare the instance variables (private, i assume). static too? so for example: Java Code: private static string firstName mh_sh_highlight_all('java');
3. i'm not sure if this program requires a constructor...being that i'm supposed to clear the program at the end anyway.
4. i create a public class declaring my input variable. example: Java Code: String first = firstName.nextLine(); mh_sh_highlight_all('java');
5. so i then i have to create methods that get/set the user input.
getter/setter example:
Java Code:
public String getFirst(){
return first;
}
public void setFirst(){
this.first = new first;
} mh_sh_highlight_all('java');
6. to print out both tags, would i write most of the code as part of a loop and make an "if" statement where the user input is valid, it prints out a tag with information, and another "if" statement that would automatically clear the buffer?
7. last i would create a tester class that would primarily be responsible for the program's output.
I am trying to find out the logic behind the Bubble sort,
for(a=1; a < size; a++)

if(nums[b-1] > nums[b]){
t=nums[b-1];
nums[b-1] = nums[b];

String c = "";
String d="";

if (number % 2 == 0 && number % 3 == 0)
System.out.println(number + " is divisible by 2 and 3");
if (number % 2 == 0 || number % 3 == 0)
System.out.println(number+ " is divisible by 2 or 3");
if (number % 2 == 0 ^ number % 3 == 0)
System.out.println(number + " is divisble by 2 or 3 but not both");
I understand the logic operators and the variable number, what i dont understand is what number % 2 == 0 and number % number == 0 mean. I know that % is a remaining operator and == means equals, i know that = and == are not the same.
