Can't Do Table Score Which Updates New Scores After Each Turn
Dec 20, 2014
i am a french student in France and i am studying informatics . For validating my term at the beginning of January i have a projet in JAVA to do called YAHTZEE. It's a game which i have to code WITHOUT USING AN OBJECTS. I already started the coding, i did all the beginning stuff ( to call the number and the names of players, to roll the 5 dices, i made the code for all the scoring points too(rules) ) but i can't do the table score which updates the new scores after each turn ( 3 turns in total) .

Given an array of scores, return true if each score is equal or greater than the one before. The array will be length 2 or more.
scoresIncreasing({1, 3, 4}) → true
scoresIncreasing({1, 3, 2}) → false
scoresIncreasing({1, 1, 4}) → true
Java Code:
public boolean scoresIncreasing(int[] scores)
{
for (int i = 0; i< scores.length-1; i++) {
if (scores[i] < scores[i+1] || scores[i] == scores [i+1]) {
return true;
} else {
return false;
}
}
return false;
}
Unsure what the problem is, it will always return True for some reason...

1.Write a JAVA program that will input 10 scores and output the Highest and Lowest score.
2.Write a JAVA program that will input the base and power and display the result: Example: Base is 4 Power is 2 the answer is 16 (Note: Math.pow( ) method is not allowed)
3.Write a JAVA program that will input an integer number, and then will output the sum of all inputted numbers. The program will stop in accepting inputs if the user entered 0.

I'm trying to write a program that asks a user how many high scores they want on a table, then the users types the inital highscores and is repeatedly asked to place more high scores on the table, which if larger than any existing high score, will take its place and shift the other scores down.
Although for the shifting and inserting of that next score the code just doesnt seem to be working, the insertScore function is where im getting the main exception, and im not sure why?
import java.util.Arrays;
import java.util.Collections;
import java.util.Scanner;
public class HighScores {
public static void main(String[] args) {
[Code] .....

I am using Eclipse programming for android. I have a game working fine but looking to add a little flare to it. Currently more scoring system just displays the current sore so if your score is 3,000 and you score 300 more it just changes to 3,300.
My question is how can I get the score to count from 3,000 to 3,300 really fast giving it the arcade feel of your score counting up? I tried timers with delays but it gets slowed down and buggy.

I am creating a program called "Mad Math Machine". This program is to generate random arithmetic questions, with integers ranging from -12 to 12, for the user to answer. The user has three lives. Once they get more than three questions wrong, they run out of lives, and their "score" (the number of questions they answered correctly) is taken.
I have the large chunk of the program (the arithmetic questions and answers) completed. The only part I am stuck on is the scoring system. I believe that arrays would be useful for this task, but I have little idea of where to start. Here is what the scoring list should be able to do:
- It should print out the top ten recent players and their scores.
- A separate list should show the top-two highest scores of all time.
*I didn't think it was relevant, but I can include the program code. Up until this point, I have created methods to keep track of the score, but I have simply left them commented out so I could build the rest of the program.*

how a JTable and respective DB table would be updated via directly editing a JTable: After table cell is updated, the setValueAt method of my custom TableModel is called to change the value of the data vector (assume I'm using vectors to store data). setValueAt then calls fireTableCellUpdated which updates the table view, and calls my custom TableModelListener.tableChanged method. Here is where I would write code to update the database.
This means an Update statement is fired each time a cell changes. Sometimes I would like to only send the Update after the entire record has been updated (and a user clicks a Save button).

I have a JFrame where some elements (one, for now) have to be centered manually on the contentPane when resizing the window or changing the window state. Resizing event (componentResized) works fine but the windowStateChanged event is causing problems because it doesn't seem to "update" the contentPane's new size properly - it keeps the previous value although the window's size is obviously changed. This can be seen by simply printing the result of getSize called on contentPane.
Centering is done by programmatically changing the constraint of the component (using putConstraint, SpringLayout). The issue is that getWidth used in that method returns "wrong" values which results in an uncentered component. Maybe another listener is needed here?
Additional info: Eclipse with WindowBuilder, Linux Mint 15, Java 1.7
I know about SSCCE guidelines but I cannot make this particular example both ready to compile and short.For unknown reasons, I am unable to post the code example. I keep getting this - "Post denied. New posts are limited by number of URLs it may contain and checked if it doesn't contain forbidden words."
addWindowStateListener(new WindowStateListener()
{
// no "@Override" was generated but it is the same with it
public void windowStateChanged(WindowEvent e)
{
System.out.println("EVENT: " + contentPane.getSize() + ", "
+ getExtendedState() + ", " + e.getOldState()); // amusingly, states are actually correct - interchanging between 0 (Frame.NORMAL) and 6 (Frame.MAXIMIZED_BOTH) when I maximize and "unmaximize"
tfArrayPanelCenter();

how do i get the inputed strings to print out after i turn them into tokens ? I need it to ask for a number and then multiple lines of strings, turn them into tokens, then print them out.
import java.util.*;
public class TokenDriver{
public static void main(String [] args){
// TokenStore words = new TokenStore();
String[] tokens = new String[300];
[code].....
also as a follow up how would use an array in an other class (TokenStore) to save the typed line information

I'm writing a java program with opengl and I'm trying to get it where the user would select something like lighting on in a JMenu and then it would turn the lighting on in the house/barn... I have a method called LightOn that I put gl.glEnable(gl.GL_LIGHT0); but it just doesn't seem to turn on when I call it from the action performed... Is there something I'm missing from my code that I'm supposed to use instead since I have tried it with a boolean.. So the boolean starts off as false and when the JMenuItem is clicked the actionPerformed will turn the boolean to true and call the method LightOn. In the display method I have what the light is supposed to be
Snippet of code in display method for lighting:
float [] whiteLight = {1.0f, 1.0f, 1.0f, 1.0f};
float [] ambientLight = {0.1f, 0.1f, 0.1f, 1.0f}; //default
gl.glLightfv(GL2.GL_LIGHT0, GL2.GL_DIFFUSE, whiteLight,0);
gl.glLightfv(GL2.GL_LIGHT0, GL2.GL_SPECULAR, whiteLight,0);
gl.glLightfv(GL2.GL_LIGHT0, GL2.GL_AMBIENT, ambientLight,0);
float [] lightPosition = {25, 25, 25, 1};

I have a problem with progress bar implementation to my project. Let me explain it;
I have Jframe named GUI. Filled with 2 datechooser combo box and 1 Buton.
And i have a Swingworker class named "MySwingWorker" for my long running task just like this;
package exampleproject;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.Level;
import java.util.logging.Logger;
[code]....
Just i want add a progress bar for listening MySwingWorker's setProgress updates. When buton clicked swingworker should executed and progress bar should come to screen. I read many articles about that but not understand correctly. Because i am beginner in JAVA.
Question1: Should i (create new class) or (implement to current gui or swingworker class) for progressbar?
Question2: Should i fired progress bar first and execute swingworker from progressbar class? or should i execute swingworker first and fired progress bar later and how?

So I'm trying to create a simple user database that I could eventually turn into a login system. I created a simple table on MySQL with a name and address for the sake of simplicity. I tried to create simple statement inside my main method that would connect to my MySQL server and when I run my program I get a ClassNotFoundException from "org.gjt.mm.mysql.Driver"..Here is what I have in my main method thus far:
public static void main(String args[]) {
try {
Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/data", "root", ""); //Connect
/*
conn.createStatement().execute("CREATE TABLE people (" + "id int(64) NOT NULL AUTO_INCREMENT," + "name varchar(255) NOT NULL," + "address varchar(255) NOT NULL," + "UNIQUE (id)," + "FULLTEXT(name, address))");

I'm trying to make a test on java. So far I'm on Question 1 and I'm having this issue. The if else statement won't allow me to add to the score.
class ExamEngine {
static CinReader Cin= new CinReader();
static int Score=0;
public static void main(String[] args) {
System.out.println("Type in your name.");
String name=Cin.readString();
[Code] ....
If I remove the "Score++;" bit, everything is fine. But I need to add to the score when they answer a question right. However, with "Score++;" there, I get this issue: 'else' without 'if'.
Note that this cannot be multiple choice, so that's why I'm using if-else, because I don't think a case system would work here.
Is there a way I can make this work while adding to the score?

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 {
public static void main(String[] args) {

Alright, so i'm working on this and what I want to do is calculate all of the answers when the values of the correct answer = 1 and the incorrect answer = -1 so at the end of the test I can calculate answer + answer2 + answer3 and so on to get a total score...How do I do this? I've been looking online for 3 hours and i'm just stumped.
import java.util.Scanner;
class HorticultureQuiz {
public static void main(String[] args){
String name;
String major;
String confidence;
[Code] ....
I thought I could make each answer = to 1 but then I would need a -1 if the answer was incorrect so I tried this.
char answer = sc.nextLine().toLowerCase().charAt(0);
if (answer == 't' || answer == 'T')
answer = 1;
{
System.out.print("Great Job, that is correct!");
} else
answer = -1;
{
System.out.print("Correct answer is false"); }
but that doesn't work!

Most of my code is done for making this Jeopardy game, the only problem I seem to have is to have variables that retain values after going through a loop, in this case the variables counter and score in the method responsePrompt
After going through the 25 questions, the value counter remains at 1, and score is either 1 or -1, nothing more, nothing less. I've had the variables initialized at 1 both inside and outside of the for loop. Full code below just in case it's something outside the method

I have a txtfile which I read and go through. My question is what are the ways I could do to read a txtfile of words and assign an empty score to each of the word in it. So each word will have a 0 value. Later on I will manipulate the score but for now I want each word to have a 0 score.What I have at the moment is reading a text file full of words eg:
private void readtextfile() {
try {
Scanner rd = new Scanner(
new File("filename"));
List<String> lines = new ArrayList<String>();
while (sc.hasNextLine()) {
lines.add(sc.nextLine());
[code]...
how to make each of the words to have a score of zero 0?
