Make A Pause Between Every Loop
Feb 18, 2015
I've been learning Java in school for lika a year now. Our teacher wanted us to make a game called "Game of Life" .Now it's not very optimized because the only type of GUI we know how to make it with JButtons so if I want a 100x100 grid that means the program has to load 10000 buttons and change text and color on them which I can imagen cause lags and so on but if we ignore that lagg our teacher wanted us to make it loop-able and well I kinda succeeded but the only problem is that I can't get it to wait between every loop so if I tell the program to loop 100 times, the program processes that and that takes forever and then updates the board and sometimes it takes forever and sometimes you cant even see the "cells" moving. Is it possible to get my program to loop and if so how? Here is the code:
//------------------------------------------------------------------------------------------------------------------------
// Hamta standardpaket
//------------------------------------------------------------------------------------------------------------------------
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

I've looped a method 14 times, each time it focuses on a different person and how many oranges he/she has eaten. I now want to calculate the total amount of oranges eaten and exactly how many oranges are eaten on average, how can I do that?? the amount of oranges eaten is variable, they are determined by what number the user types in.

What I want to do is very clear, just play sound and pause it. The problem is that I can't pause the music. When I click the pause button music keeps playing .I have been working on for 2 hours. I can't find the mistake; what am I doing wrong?
public class MainC extends JFrame implements Runnable,ActionListener {
private JPanel contentPane;
private JTextField txtname;
JButton btnopen;
JButton btnSave;
JButton btnplay;

Here I want to make a simple program where a Ball keep bouncing forever, then I add a MouseClick Listener to stop and resume thread (I mean, to stop moving Ball and to resume again). The problem is I can stop the thread using wait(), But I can not resume it. Below is the code
public class TestResumePauseBall {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public synchronized void run() {
Field aField = new Field();
[code]....
At first I think that notify() must be called from another active thread. So I add a 'class Timing implements Runnable'. Then I call notifyAll() from class Timing. But still it was failed.
After wait() called on Ball's thread, the whole frame also freeze. I can not understand why this happen?
If this test success, I will add 1 one more ball and add keyboard keys as controller of ball's movement.

I am coding a game and I am trying to implement a pause and unpause button. in the BoardPanel class I've added the button's 'p' and 'o' to game.wait() and game.notify() (main code is in game class). however the game.wait is having issues and even if i throw interrupted exception or try/catch it doesn't work. I'd like to code it to a single button if at all possible.

We are making a tic tac toe game for my CS120 class and I am having trouble figuring out how to make our X's and O's. Is there a way to make shapes besides making two lines for an X and an oval with a white smaller oval inside to make an O? We have only learned the basics so far in class (i.e. events, inheritance, client-supplier, etc.)
These are our instructions:
Write a controller that controls the game. There is one human player (the X player) and the computer player (the O player). The name of the class must be TicTacToeController. In a sense, the controller is the game since the controller will 1) create a TicTacToeModel 2) create a TicTacToeView and 3) create a TicTacToeButton (you must write this class following the design pattern covered in class lectures), a label, and text field such that when the button is pushed, the player moves into the cell selected by the text field. After every player move, the computer moves into a randomly selected empty cell. When the game is over, a text message must be displayed somewhere on the screen the gives the status of the game. While you are free to change the appearance of the controller, the basic elements must be provided (a view of the game, a button, and a text field to enter the cell). A sample screenshot is displayed below.And this is the code i have thus far:
[import java.awt.*;
import javax.swing.JFrame;
public class TicTacToeView extends Rectangle
public TicTacToeView(int x, int y, int w, int h) {
super(50,60,w,h);
this.setBackground(Color.red);
JFrame win = new JFrame("Tic Tac Toe");
win.setBounds(10,10,w+100, h+100);
win.setLayout(null);
win.setVisible(true);
win.setBackground(Color.gray);

I am trying to print a loop inside an array of a greater size than the loop itself. Like for example I have an array of size 7 but it has only 3 elements.
int[] array=new int[7]
array[0]=2;
array[1]=3;
array[2]=4;
now what I want to do is print these three numbers in a loop so that my array[3]=2;array[4]=3;array[5]=4 ...... till the last one. Also the array could be any size and not just 7.

Here's the code: it's while loop inside a for loop to determine the proper length of a variable:
for (int i = 0; i < num; i++) {
horse[i]=new thoroughbred();
boolean propernamelength = false;
while (propernamelength==false){
String name = entry.getUserInput("Enter the name of horse "
[code]....
I was just wondering what was going on here -- I've initialized the variable, so why do I get this message? (actually the carat was under the variable name inside the parentheses.

I have everything else working. My problem is that when i type "quit" to close the outer loop. It still runs the inner loop. The National Bank manager wants you to code a program that reads each clients charges to their Credit Card account and outputs the average charge per client and the overall average for the total number of clients in the Bank.
Hint: The OUTER LOOP in your program should allow the user the name of the client and end the program when the name entered is QUIT.In addition to the outer loop, you need AN INNER LOOP that will allow the user to input the clients charge to his/her account by entering one charge at a time and end inputting the charges whenever she/he enters -1 for a value. This INNER LOOP will performed the Add for all the charges entered for a client and count the number of charges entered.
After INNER LOOP ends, the program calculates an average for this student. The average is calculated by dividing the Total into the number of charges entered. The program prints the average charge for that client, adds the Total to a GrandTotal, assigns zero to the Total and counter variables before it loops back to get the grade for another client.Use DecimalFormat or NumberFormat to format the numeric output to dollar amounts.
The output of the program should something like this:
John Smith average $850.00
Maria Gonzalez average $90.67
Terry Lucas average $959.00
Mickey Mouse course average $6,050.89
National Bank client average $1,987.67
Code:
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String name = "";
int charge = 0;
int count = -1;
int total = 1;
int grandtotal = 0;
int average = 0;

I am trying to make a program add values from a loop. So what its supposed to do is search through tokens on an imported file. The file lists State, Capital, and then capital population. Then take the population string, turn it into numbers, and then do stuff with the numbers. First I'm supposed to find the Highest and lowest population of the places in the file (which I did without problem), but the finally thing is I'm supposed to add each found population to the last so I can find the average of the populations.
I just cannot seem to grasp how to do that. I THINK I'm supposed to some how store the given value into a variable, but how do I get that variable to add to the new value?
like...?
Get token -> a
b = a
c = a + b
or wait no.....
Java Code :
import java.io.*;
import java.util.Scanner;
public class CapPopS
{
public static void main(String[] args) throws IOException
{
File stateCAP = new File("state-capital-2004population.txt");
if (!stateCAP.exists())
[Code] ....

I first learned how to program with BYOB. In BYOB there were variables and lists. Variables worked the same as Java and lists were groups of variables. To create a list, I would give it a name. I could then add variables to this list as items throughout the program. Here's an example of what a list would look like:
[[List]]
item 1: Hello
item 2: world
I could then call upon item 1 or item 2 and delete them if needed. In Java, I want to have 3 lists of variables into which I put user input as variables. The code would look something like the following: (stuff with "//" at the end is detailing what I want to do, not actual working code)
import java.util.*;
public class Archives {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);

I am currently in the progress of making a GUI for a project. I am trying to make a maze and I need it displayed in a GUI. So, I thought I would be able to do that with a text file that I created. The code I have for it so far runs and compiles but it is not displaying my text file as a GUI, even though it reads the file. All I get are a bunch of green rectangles. I am using Netbeans to code this
package rectangles;
import java.awt.Color;
import java.awt.Graphics;//this will draw the maze
import java.awt.Graphics2D;//
import java.io.BufferedReader;
import java.io.FileNotFoundException;//handles file

public static final String NAME="JAVATAR";
"final" makes sure the constant has the same value and prevents it from being changed. So why add "static" to make it a constant. I figured the reason a few weeks back but don't remember it now.

First, I have a figure that moves around the screen. It uses keylisteners and just subtracts or adds pixels. However, I notice the movement is not smooth at all. It is very rigid and laggy movement. How can I make it smoother movement?
Second, you get three lives in the game. The lives are subtracting correctly, but I want the game to say "GAME OVER" on a dialog box. How would I get this to happen? My JFrame and my life int are in separate classes. I know I should use an if statement, saying if lives are at or less than zero, open the box, but how do I open the box?
Third, I want to display the time on the screen. I have a swing timer, but how do I put it on the screen? DrawString is not working for me.
Fourth, I want to set an icon for the game, the code is running, but not doing anything.
Java Code: frame.setIconImage(Toolkit.getDefaultToolkit().getImage("/Users/MW/Downloads/petericon.jpg")); mh_sh_highlight_all('java');

I was thinking to make a game where a button is appearing in random spots and you have to click it, and once you click it you're score goes up. But I don't know how to make the score appear in the JFrame, and I want the score to update everytime the Button is Clicked.
Here is the code:
Java Code:
package clickmegame;
import java.awt.Dimension;
import java.util.Random;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class ClickMeGame {
