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.*

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 stuck on what to put in my functions for this question: Write a program to maintain a list of the high scores obtained in a game. The program should first ask the user how many scores they want to maintain and then repeatedly accept new scores from the user and should add the score to the list of high scores (in the appropriate position) if it is higher than any of the existing high scores. You must include the following functions:
-initialiseHighScores () which sets all high scores to zero.
-printHighScores() which prints the high scores in the format: "The high scores are 345, 300, 234", for all exisiting high scores in the list (remember that sometimes it won't be full).
-higherThan() which takes the high scores and a new score and returns whether the passed score is higher than any of those in the high score list.
-insertScore() which takes the current high score list and a new score and updates it by inserting the new score at the appropriate position in the list
here are my functions the insertScore is missing because I am having troubles with it.
public static void initialiseHighScores (int[] scores, int size)
{
for (int i = 0; i < size; i++)
{
scores [i] = 0;
}
}
public static boolean higherThan (int[] scores, int size, int newScore)
{
[Code]...

a project I am working on. Its a program that creates a singly linked list that stores names and high scores and prints them. For some reason it is printing an entry extra times. Also my remove function is not working properly
GameEntry class:
package project;
public class GameEntry implements Comparable<GameEntry> {
private String name;
private int score;
public GameEntry(String n, int s) {
name = n;

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!

I've been working on this same assignment using netbeans. I've completed the exercise and when I run it, it works. However, netbeans still had errors listed in the left hand numerical column and it asks me if I still want to run the program with errors when I hit run?
package TestScores;
import java.util.Scanner;
// Name: Joe
// Date: ........
// Desc: Test Score Averages
[code].....
I found this thread while doing a google search trying to find out the error in my code.

So I'm working on this game for a school project and I have 2 problems
1.I do not know how to display the players score in the panel
2.Every single time the console reads the second button I click on as a 0 instead of the number underlining it
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

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

I'm working on a homework assignment and I keep getting a compiler message this is the message
GradesAverage.java:44: error: variable totalgrade might not have been initialized
System.out.println("Over all you have " + totalgrade);

The homework is this Write a program that has variables to hold three test scores. The program should ask the user to enter three test scores and then assign the values entered to the variables. The program should display the average of the test stores and the letter grade that is assigned for the test score average. Use the grading scheme in the following table:
Test Score Average Letter Grade
90-100 A
80-89 B
70-79 C
60-69 D

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) .

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?

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...

I`m trying to make a gradebook that uses random number generator to give the score, I also need to implement student numbers and sort everything with a total at the bottom. But I cant figure out how the bubblesorting works. This is my code so far:
package karakterbok;
import static java.lang.Math;
import java.util.Random;
public class Karakterbok {
public static void main(String[] args) {
Random karakterer = new Random();
Random studid = new Random ();
[Code]...
how to sort this using bubblesort?

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 created this code, seems like it should be working properly and the code is right, but the output is not what it should be.The action gets a List<Integer> and should make it reversed.
As example: 1 2 3 4 5 ---> 5 4 3 2 1
The Nodes in the new list (lst2) should be in a reversed position.The code does compile with no errors.I do have Node<T> and List<T> classes
Java Code:
public class NodeReverse
{
public static void reverse (List<Integer> lst, Node<Integer> node, int counter, List<Integer> lst2, Node<Integer> pos) // Should make lst = lst2 while lst2 is the opposite to lst
{
node = node.getNext();
counter++;
if(node.getNext()!=null)
reverse(lst, node, counter, lst2, pos);

I have some class called sorted to sort the linked list through the nodes of the list. and other class to test this ability, i made object of the sort class called "list1" and insert the values to the linked list.
If i make other object called "list2" and want to merge those two lists by using method merge in sort class. And wrote code of
list1.merge(list2);
How can the merge method in sort class know the values of list1 that called it as this object is created in other class.

I have a list of 100,000 + names and I need to append to that list another 100,000 names. Each name must be unique. Currently I iterate through the entire list to be sure the name does not exist. As you can imagine this is very slow. I am new to Java and I am maintaining a 15+ year old product. Is there a better way to check for an existing name?

I receive a java.lang.NumberFormatException: For input string: ""DepDelayMinutes"" error when trying to filter a list and then assign the results to a new list.
I have edited the code so it is an int that throws the exception so it isn't the presence of a string that is causing the error - java.lang.NumberFormatException: For input string: ""0914"" .
I believe the issue is because of the two sets of double quotes but I do not understand how they came about. The original dataset does not have any quotes whatsoever.
import java.util.HashMap;
import java.util.LinkedList;
import java.util.List;
import java.util.Map;
import java.util.function.Predicate;

So we have an assignment regarding a linked list implementation of a given list interface.
In my list interface, the method contains(T anEntry) is defined.
In the LList implementation, contains is already implemented as part of getting the core methods in.
Now I am being tasked with the following:
Provide a second implementation of the method contains2(T anEntry) that calls a private recursive method
Private boolean contains (T anEntry, Node startNode) that returns whether the list that starts at startNode contains the entry anEntry.
I've written the private recursive method already. That's not an issue (at least not right now).
But what I don't understand is how startNode is supposed to be populated when this private contains method is called from the public contains2 method? contains2 only takes one parameter: anEntry. the private method takes two parameters: anEntry and startNode. How am i supposed to provide startNode when I am calling contains2?
