Any good java programmers out there?

I need some help with my homework, my professor is such a dusch when it comes to helping us with the homework. I've sent him an e-mail since last thusrday and I have not heared from his ass. Anyways here's the intructions.

7.10 Use the Question class from Chapter 6 to define a Quiz class. A quiz can be composed of up to 25 questions. Define the add method of the Quiz class to add a question to a quiz. Define the giveQuiz method of the Quiz class to present each question in tuurn to the user, accept an answer for each one, and keep track of the results. Define a class called QuizTime with a main method that populates a quiz, presents it and prints the final results.

7.11 Modify your answer to Programming Project 7.10 so that the complexity level of the questions given in the quiz is taken into account. Overload the giveQuiz method so that it accepts two integer parameters that specify the minimum and maximum complexity levels for the quiz questions and only presents questions in that complexity range. Modify the main method to demonstrate this feature.

Here's the Quiz class from chapter 6

import java.util.Scanner;
public class Question implements Complexity

{

private String question, answer;
private int complexityLevel;

public Question (String query, String result)
{
question = query;
answer = result;
complexityLevel = 1;
}

public void setComplexity (int level)
{
complexityLevel = level;
}

public int getComplexity()
{
return complexityLevel;
}

public String getQuestion()
{
return question;
}

public String getAnswer()
{
return answer;
}

public boolean answerCorrect (String candidateAnswer)
{
return answer.equals(candidateAnswer);
}

public String toString()
{
return question + "\n" + answer;
}

}

thanks for the help

bump anybody? let's make this interesting, there will be a reward for it. here is the rest of the working codes, just once section needs to be modified (which I don't know how to) to make it perform as specified. The one italized is the one that needs to be modified.

Just add this method/function under the regular giveQuiz method... This is an example of overloading. Simply changing the parameters the class accepts. If you want to make it even more interesting. Add a counter to how many questions it actually asks. Instantiate a new public variable named totalQuestions so at the end, the score will be in the format:
getScore() + "/" + totalQuestions

What's my prize? (Nothing like incentive to get things moving)

have you tried to compile this? I tried to get it to work on my program, but it will not compile. Oh the prize is 20 bucks to be exact.

What is the error msg? As I don't have a java compiler on this machine.

IJava\Quiz1\Quiz.java:43: cannot find symbol

Nothing like leaving a couple simple symbols out. Heh:

public int giveQuiz(int lowComplex, int highComplex)

{

Scanner scan = new Scanner (System.in);


String candidateAnswer;

//System.out.println ("Enter complexity level from 1-5:");
//scan.nextInt();
//scan.nextLine();


for (int i = 0; i < numQuestions; i++)
{

if (questionHolder.getComplexity() >= lowComplex && questionHolder.getComplexity() <= highComplex)
{
System.out.println(questionHolder.getQuestion());
candidateAnswer = scan.nextLine();
}

if (questionHolder.answerCorrect(candidateAnswer))

score++;
}
return getscore();
}

//Replace questionHolder.getComplexity with questionHolder.getComplexity()

man I thought you had it, but now it pose another problem. It compiled just fine but the error now is due to public int giveQuiz(int lowComplex, int highComplex)

here's the new error
IJava\Quiz1\QuizTime.java:102: giveQuiz(int,int) in Quiz cannot be applied to ()
System.out.print(T1.giveQuiz());
^
1 error

Tool completed with exit code 1

oh yeah another thing, I played with it and deleted the int on the public int giveQuiz, instead I initialized it on the very top:

private int score;
private Question[] questionHolder = new Question[25];
private int numQuestions;
private int Complexity;
private int lowComplex, highComplex;

now everything compiled, but when you run the program, it asks you for the complexity level you want but it does not display any questions.

Replace T1.giveQuiz() with T1.giveQuiz(1, 3)

This will display questions between complexities 1 and 3.

Change the 1 and 3 numbers with any number between 1 and 5...
Just make sure the first number is smaller than the second.

Leave the int on the giveQuiz... that returns your score to the print line method.

ok now I understand what you did, but the instructions asked that let's say, you wanted complexity 3, it will display all the question that have the complexity 3 and not 1-3. Is there a way to change that to make it respond only to the entered complexity?

Here is the program as it is:

import java.util.Scanner;
public class Quiz

{
private int score;
private Question[] questionHolder = new Question[25];
private int numQuestions;



public Quiz()
{
this.score = 0;
this.numQuestions = 0;

}

public void addQuestion (Question Q)
{
this.questionHolder[numQuestions++] = Q;
}

public int giveQuiz(int lowComplex, int highComplex)

{

Scanner scan = new Scanner (System.in);

String candidateAnswer;

System.out.println ("Enter complexity level from 1-5:");
scan.nextInt();
scan.nextLine();


for (int i = 0; i < numQuestions; i++)
{
if (questionHolder.getComplexity() >= lowComplex && questionHolder.getComplexity() <= highComplex)
System.out.println(questionHolder.getQuestion());
candidateAnswer = scan.nextLine();
if (questionHolder.answerCorrect(candidateAnswer))
score++;
}
return getscore();
}
public int getscore()
{
return score;
}
public String toString()
{
return getscore() + "\n";
}

}

where is your

public int giveQuiz()
{
...
}

method defined?

Show that to me and I will show you what to change...

--------

What I would do.

Define a new method named startQuiz:

public startQuiz()
{
private int answer;
private int complexity;
private int lowComplexity, highComplexity;

System.out.println("Would you like 1 complexity level or multiple complexity levels? (1: 1 Level | 2: Multiple Levels) ");
answer = scan.nextInt();
System.out.println();

if answer = 1
{
System.out.println("Enter Complexity Level (1-5 ");
complexity = scan.nextInt();
System.out.println();

System.out.println(giveQuiz(complexity, complexity));

} else {

System.out.println("Enter Min Complexity Level (1-5 ");
lowComplexity = scan.nextInt();
System.out.println("Enter Max Complexity level (" + lowComplexity + "-5 ");
highComplexity = scan.nextInt();
system.out.println();

system.out.println(giveQuiz(lowComplexity, highComplexity));
}

instead of the giveQuiz(...) method in the main execution block, place just a single startQuiz() method

I'm not sure what you are asking. the giveQuiz method that I have was the one you changed to public int giveQuiz(int lowComplex, int highComplex) then the rest as you saw in my previous post.

Here is the direction I have to follow:

7.11 Modify your answer to Programming Project 7.10 so that the complexity level of the questions given in the quiz is taken into account. Overload the giveQuiz method so that it accepts two integer parameters that specify the minimum and maximum complexity levels for the quiz questions and only presents questions in that complexity range. Modify the main method to demonstrate this feature.

leave the original giveQuiz() method.

The point of overloading is having the same method just with different parameter you can to it.

Follow my previous post and that should do what you want of it.
