Counter And Score Variables In Jeopardy Game?

Apr 21, 2015

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

import java.util.*;
import java.io.*;
public class Project10
{
public static void main(String[] args)
throws java.io.IOException

Accessing Variables - What Is The Final Value Of Counter

Mar 7, 2015

While reading head first java i encountered a problem(Pg. 90 chapter 4 - mixed messages).

Suppose in a class(say A) outside main() a counter variable is declared and initialized to 0.

In main() declared the array of objects of the class A.

Consider a while loop in which we increment the counter as follows:

public class A{
int counter = 0;
public static void main(String[] args){
A[] arr = new A[20];
int x = 0;
while(x<4){
arr[x] = new A(); //arr[] is array object
arr[x].counter += 1;
x++;
}
}
};

what is the final value of counter ? will it be the same for all array objects.

Making Counter AI For Connect 4 Game?

Apr 28, 2015

I am a student in an intro to computer science class working on my final project. This is essentially a game of connect 4, but only requiring 3-in-a-row for victory. We were given the base game and a sample file to work with to make an AI that beats our professor's ai in the base game. Here is the base game

package cs110.project3;

Animating Score To Count Up Or Just Displaying Score

May 30, 2014

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.

Creating A Score List And High Score List?

Jan 7, 2015

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.*

If Else Statement Not Allow To Add To The Score

Mar 13, 2014

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?

How To Make The Score Appear In The JFrame

Mar 28, 2014

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 {

Adding Values - How To Get Total Score

Jan 11, 2015

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!

Assigning Empty Score To Strings In Text File

May 27, 2014

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?

Array Of Scores - Return True If Each Score Is Equal Or Greater Than One Before

Mar 8, 2014

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...

Implementing A FPS Counter

Jan 17, 2014

Ok, so I'm making a game with a space ship that flies around the universe and discovering new planets. It works fine so far, but I'm looking to make it perform better and be better compatible with lesser-processors.So, I'm trying to put in an FPS counter and an entirely new game loop so that my game can decide for me what FPS I should use.

I have two classes. Heres the big, main one: [Java] package cyentw.game.src; import java.awt.Color; import java.awt.Font; impor - Pastebin.com *I want to change the loop and put an FPS counter in around line 456, you can scroll past the rest if you'd like*And heres the init frame one, in case you'd like to see it for some reason.

Java Code:

package cyentw.game.src;
import javax.swing.JFrame;
public class Start extends JFrame{
public static JFrame frame;
public static int WIDTH = 500;
public static int HEIGHT = 500;
public Start() {

[code]....

how to make my game loop as quickly (or a bit slower) as it can, and my FPS is static.

Second Counter To Minutes

Apr 7, 2014

I have a timer where it counts down from 300 to 0 then does something. But I want the display for the clock to show the time in minutes. I tried:

double showTimeLeft = timeLeft / 60;
o.setDisplay(String.format("%.2f", showTimeLeft) + " Minutes");

But Every so many seconds it skips like:

Time = 3.38
Time = 3.37
Time = 3.35
Time = 3.34

It skipped 3.56

How to do this right?

Increment Counter By Recursion

Mar 22, 2015

I have a question related to the code below, that I do not understand. The aim is to count all files and subdirectories in an ArrayList full of files and subdirectories. So I have to count every file and every subdirectory.

The code concerning counting files is clear to me - every time d is of the type file I have to increment n by one. However I thought that I have to do the same thing in case d is a directory, so I would have written the same code for directories.

So what does "n += ((Directory) d).countAllFiles();" mean? In my understanding the method countAllFiles() is applied again on the object Directory ( as Directory is the class that contains this method), but how is n incremented by this? I thought n should be incremented by one as we did with files.

public int countAllFiles() {
int n = 0;
for(SystemFile d : content) {
if(d instanceof File) {
n++;

Confirm Dialog And Counter

Mar 29, 2014

This is the code I have written so far. This program calculates tax from multiple tax payers.

import javax.swing.JOptionPane;
public class CalcutateTax
{
public static void main (String [] args)

[code]....

The problem is I cant think how to ask the use if he wants to calculate tax due for another taxpayer. If the user says yes, keep calculating, otherwise exit from the program. And how do I keep count of how many people got their tax calculated? Say for example,

JOptionPane.showMessageDialog (null, " We calculated tax for " + xnumber + " number of people.");

This is the question asked on my assignment ask the user if he wants to calculate the tax due for another taxpayer if so, do it again.At the end of the main method, output a message in a dialog box that says: Hello, We calculated taxes for [number of taxpayers].replace [number of taxpayers] with the actual number of taxpyers you calculated taxes for.

Declare Counter With Value Outside For Loop

Mar 29, 2015

Is it possible to declare a counter with a value outside of a for loop?

I have a counter that will end prematurely in a while loop during various iterations and I want to pick it back up in a catch all for loop at the end

Let's say I have a while loop

while(something) {
total++
}

then after I have a for loop that I want to start at total but would rather do that then make a new counter variable.

for(total;total < 20;total++)

Is something like this possible or is this a horrible thing to want anyways?
