Generate Set Of Test Scores Between 0-100 Inconclusive
Dec 8, 2014
Design and write a Java program that will generate a set of test scores between 0-100, inconclusive. The exact umber of scores is determined either randomly or by the user input. There should be a minimum of 5 test scores. The program calculates the average of all test score in this data set. Then it asks the user how many scores are to be dropped and drops that number of low scores. The average is recalculated.
Output of this program:
The original test scores printed in rows of 10 scores
The average before low scores are dropped
The number of low scores to be dropped
The list of low scores dropped
The new average

Write a program in JAVA in response to the following prompt:
Design a GUI program to find the weighted average of four test scores. The four test scores and their respective weights are given in the following format:
testscore1 weight1
...
For example, the sample data is as follows:
75 0.20
95 0.35
85 0.15
65 0.30
The user is supposed to enter the data and press a Calculate button. The program must display the weighted average.
Here is what I have written:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class weightedaverage2 extends JFrame {
private JLabel Score1L,Score2L,Score3L,Score4L;

It is giving me a the validate sentence over and over even when i type stuff in. I have searched up how to do the .equals to a string but it doesn't give me a accurate enough to my problem.

Write a program that asks the user to enter five test scores. The program should display a letter grade for each score and the average test score. Write the following methods in the program:
calculateAverage This method should accept five test scores as arguments and return the average of the scores. determineGrade This method should accept a test score as an argument and return a letter grade for the score, based on the following grading scale
Score Letter Grade
90-100 A
80-89 B
70-79 C
60-69 D
Below 60 F
double test1,test2,test3,test4,test5;
double average;
char grade;
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter the first score");
test1 = keyboard.nextDouble();
System.out.println("Enter the second score");
test2 = keyboard.nextDouble();

If this method returns the lowest score, how do I return the 2 lowest scores.
For example If I input 1, 2, 3, 4, 5 this code will return 1.
How do i return the two lowest scores, for example if I input 1, 2, 3, 4, 5, I want to return 1, 2
public double getLowestScore() {
smallest = testScores[0];
double sum = 0.0;
double total = 0.0;
double Average = 0.0;

So for this project I'm going to take in some quiz scores, then eventually get the total number, the range, the mean, and others... Here's the instructions for the two methods I need to create but am completely stuck on:
2. public boolean inputData(Scanner in)
2.1.takes in a Scanner object passed in from main()
2.2. asks the user for a number in the range of 0 through 100.
2.3.It must read a number into an integer variable unless a non-number value is entered, in which case the method will return false. You may use try/catch or an if statement for this.
2.4.If the datum/score seems acceptable, the addGrade method must be called.
2.5.If addGrade returns false, then inputData should throw an IllegalArgumentException or return false
Otherwise, inputData should return true. See section 11.4 for exceptions.
3. public boolean addGrade
3.1.takes in an integer grade. If grade is not in the range of 0 through 100 the method should return false.
Otherwise, it should appropriately change the values of numberOfQuizzes, highValue, lowValue,
3.2.totalQuizScore , sumOfSquares (used in variance calculation), and add one to the count of the proper variable for A's, B's, C's, D's or F's. The method should then call calculate and return true
Now I have done very little with booleans in class at all, so this is all very confusing for me. I've tried to do a lot of research on my own and so far I came up with the following for the two methods above:
public boolean inputData()
{
int score = 0;
System.out.println("Please enter values, Q to quit:");
Scanner in = new Scanner(System.in);
while (in.hasNextInt())
[Code] ....
Honestly I'm not really sure what I'm doing wrong at all, and I have done a lot of research but can't really find anything too similar to what the instructions want so I'm not sure what's right/wrong.

I'm writing a program that is about rolling "dice" and getting the scores to add up to 100. There are two players in the game and each must take turns rolling dice choosing whether or not to keep rolling dice and accumulating more points during their turn while risking their points being lost by rolling a 1 or to add their turn points to their total points. The question I have is how would I exit the do while loop if the player chooses to add their turn score, thus adding their score and ending their turn?
Here is the coding so far.
Java Code:
import java.util.Scanner;
import java.util.Random;
public class Pig
{
public static void main(String[] args)
{
int die; int userTotalScore; int userTurnScore; int compTotalScore; int compTurnScore;

Alright, so, for my CS project, we're supposed to list diving scores. However, there are four sections (which I've made in the code) and each section has 9 scores. Of those nice scores, the highest and lowest must be eliminated and then the total needs to be figured out. We're supposed to be using arrays for this...
import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;
public class Diving {
public static final int MAX_DIVES = 51;
public static void main (String[] args) {

I have a project that is asking me to create a program that will handle a Golfer and his scores. The program will be comprised of three classes: a Golfer class that will manage all the golfer's scores, a Score class and a Tester class to drive the other classes. To accomplish this task the program will use a partially filled array to store the golfer's scores. I have the majority of the code written. It compiles fine, but when I compile and run it only gives the following output.
Tiger ID Number: 1001 Home Course: Pebble Beach
Score Date Course Course Rating Course Slope
[LScore;@15db9742
I am not sure what I am doing wrong. I have been over and over the code. It is also only printing one golfers information. I have tried creating a for loop for the for the toString in the Golfer class but I am getting the following error Golfer.java:117: error: missing return statement.
I am at a loss here is the code I have for the three sections.
public class Golfer
{
private String name;
private String homeCourse;
private int idNum;
private Score[] scores;
private static int nextIDNum = 1000;

Write a program that reads student scores, gets the best score and then assigns grades based on the following scheme:
Grade is A if score is >= best - 10;
Grade is B is score is >= best - 20;
Grades is C if score is >= best - 30;
Grade is D if score is >= best - 40;
Grde is F other wise;
The program prompts the user to enter the total number of studeents, then prompts the user to enter all of the scores, and concludes by displaying the grades.
import java.util.*;
public class AssigningGrades
{
public static void main(String [] args)
{
Scanner scan = new Scanner(System.in);
int studentNumber = 0;
int classScore = 0;
[Code] ....
So when I ran into problems when populating the array and I made changes. Then all of a sudden the program doesn't recognize classSize[i] at the System.out.print line.

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 am a beginning programmer and was learning how to make an XML. It was for a simple game and only needs to hold the highscores of three different levels. Here is what I coded:
try {
OutputStream fout= new FileOutputStream("highScores.xml");
OutputStream bout= new BufferedOutputStream(fout);
OutputStreamWriter out = new OutputStreamWriter(bout, "8859_1");
[code]....
My issue is that I run this code every time I create the program and the scores are reset to 0. How can I make a small change so that I only run this block of code and create the XML the first time the program is run?

I was trying to write a program that will accept values and transform the scores to grade. Like 70 and above will be given A from 60 to 69 is B, from 50 to 59 is C, from 40 to 49 is D and below 40 is F. I have defined the variables, for the textfield, am confused on how make this hapen on just a click of the comand botton.

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 {

Assignment: Given an array of scores sorted in increasing order, return true if the array contains 3 adjacent scores that differ from each other by at most 2, such as with {3, 4, 5} or {3, 5, 5}.
scoresClump({3, 4, 5}) → true
scoresClump({3, 4, 6}) → false
scoresClump({1, 3, 5, 5}) → true
Codingbat AP-1 3rd question
public boolean scoresClump(int[] scores) {
for (int i = 0; i < scores.length; i++) {
int a = scores[i];
int b = scores[i + 1];
int c = scores[i + 2];
if (Math.abs(b-a) + Math.abs (c-b) <=2)
return true;
}
return false;
}
I got it right for some of the input, but not one of them. I tried to use the for loop and if statement on a specific input that I got wrong:
{4, 5, 8}
scores[1] - scores[0] = 1
scores[2] - scores[1] = 3
I suspect it has something to do with the for loop, but I don't see the problem with it. It should work, shouldn't it?
But anyway, here is the error for {4,5,8} :
Exception:java.lang.ArrayIndexOutOfBoundsException : 3 (line number:7)

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)
{

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...

"which code is best for randomly generating integer 0 or 1". Haven't gotten my grade back yet but in reading these during the test I didn't think any of these would kick out both of those numbers, but there was no "none of the above" option on the test.This is exactly how it appeared on the test:
A) (int)Math.random() + 1
B) (int)(Math.random() + 0.2)
C) (int)Math.random()
D) (int)(Math.random() + 0.8)
E) (int)(Math.random() + 0.5)
I've tried all of them in the cs lab 100 times each and none of them generated both numbers. 'A' kicked out 1 every time. 'B,D and E' kicked out 0.2, 0.8 and 0.5 respectively each time, and 'C' kicked out 0. Did I just not run them enough times for the result to change or am I right in thinking there's a glitch on the test?

I have a large product with many maven projects, all of which can be hierarchically tracked back to the same parent. The projects have javadocs and whatnot.
Icommand line instructions (Windows 7) to generate the full API documents html on my local machine (of all the projects together). If there is a maven command for doing this from the CMD, more the better.
