I have two different parts to my program. My FundRaising.java is my problem. I'm having problems with my print statements. Why are the correct numbers not showing up? I keep getting 0.
System.out.println (booster1);
System.out.println (booster2);

I ask the question to get the numbers and I keep on getting 0
System.out.println ("What is the sales for the first week:");
numBoxes = scan.nextInt();
booster1 = numBoxes.BandBooster(name);

for (int i = 0; i < itemCount; i++)
	    contents += cart[i].toString() + "\n[B]"[/B]

	contents += "\nTotal Price: " + fmt.format(totalPrice);

First of all, I think you missed a " after the \n inside the loop.
Secondly, cart is an int. Where did you see written that ints have methods?
The cart doesn't have a method toString because it is an int. You can't make up from your mind methods and call them and then wonder why the code doesn't run.

This is going to work:

for (int i = 0; i < itemCount; i++)
	    contents += cart[i] + "\n";

cart is supposed to be an array. Am I doing arrays properly? I can't find very much documentation on arrays.

I don't understand what you are trying to say.

Can someone please tell me why "int can not be dereferenced" here.
contents += cart.toString() + "\n

    {
        int[] cart = new int [capacity + 3];

}

I figured out the problem.
double Correct = 0;
double Incorrect = 0;
On that part I needed to move it down farther in the code so it reinitialized to 0 to reset the count.

Here's the full working code if anyone is curious.

            phrase = scan.nextLine();
        }


    }
}

I think you would need a for loop
That performs quizzes.length loops

int num = quizzes.length;
for(int quiz=1;quiz<=num;quiz++)
{
...
}

And then quiz is your quiz number which you can use inside loop if you want, to display the number of the quiz.

I can't get that to work no matter how I try it :(.

Got the part above. Now I'm having problems with this part.
System.out.println("How many quizzes would you like to grade");
Quizzes = scan.nextInt();

int[] canswers = new int[Questions];

While(!=Quizzes.length)

I would like to grade however many quizzes I input above, so I would think I would need some kind of while loop. What kind of loop would I need to make that work? Here is my full code now.

Multiply 100 times your percentage which should be a decimal number? If you elaborate on the purpose of this people be able to think of more ways. There's also a for loop and while loop. Doing an array would also be possible if you gave a list of numbers.

After I ask the user to enter a number here
System.out.println("Enter a number");
number = scan.nextInt();
I would like print the id of each salesperson that exceeded that value and the amount of their sales. I Also want to print the total number of salespeople whose sales exceeded the value entered. So I would think I would need some kind of for loop and several print statements. This is what I am thinking for my for loop.
for (int i=0; number<i; i++)
Line 1 to line 56 is good. After that is where I am trying to put my for loop.

If you haven't specified a modifier and they are in a different package, they are private.

Use a public method getName() to get the name - don't access the variable directly.

When you say modifier I assume you mean public, private, and protected? And not sure what you mean by package. Could you explain what you mean by package please.

If you have declared it private then you will need to use a public getter method to get the name. Same for balance.

I don't even see the word private. Any ideas why it thinks it is private?

Well, move it outside main(). Cut-paste the entire thing outside of the braces that delimit the main() method.

Ok. Any idea about this part?
In my if statement It says name has private access in account. What does that mean and how do i fix it?
if((accnt1.name).equals(accnt2.name))

How would I do that? And what about the second question?

Why is this an illegal start on an expression? public Account consolidate(Account accnt1, Account accnt2)
In my if statement It says name has private access in account. What does that mean and how do i fix it?

Something like this. Except my program is way simpler.

Close out a public void close().

Again, that depends on what you mean by 'closing an account'. Typically you'd close an account by removing all the money from it, i.e. withdrawing all money from your bank account, then just deleting it or somehow marking it as closed. But we are just programmers, if you need help with implementation or errors that's fine, but I doubt you'll find much help on how to interpret your project's requirements. Is this for a class? If so speak to the professor.

I'm trying to do some form of account.close();. No matter where I put it in my program it won't work :(.

What is a consolidated account? Just an account under both names? What do you have to do to 'make an account consolidated'?

Thats one of my problems. I have no clue. I can't find anything useful in my book or online. What about the second part? How would I close the first account?

I'm trying to do some consolidation but I'm not sure on the specific rules of consolidation so I'm having A LOT of difficulty on it. Here's what I'm trying to do.
Write a program that prompts for and reads in three names and creates an account with an initial balance of $100 for each. Print the three accounts, then close the first account and try to consolidate the second and third into a new account. Now print the accounts again, including the consolidated one if it was created.
I'm having difficulty with closing the first account then Consolidating :(. Here's my code so far with no errors so far.

//***********************************************************
// TestAccounts1

import java.util.Scanner;

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

        String name1;
        String name2;
        String name3;
        double balance = 100.00;
        int balance1;
        int balance2;
        int balance3;

        //declare and initialize Scanner object
        String message;
        Scanner scan = new Scanner (System.in);

        //Prompt for and read in the names
        System.out.println ("What is the first name? ");
        name1 = scan.next();

        message = scan.nextLine();
        //balance = balance1;

        System.out.println ("The first name is: \"" + name1 + "\"");
        System.out.println("The balance for this acoount is:" +balance);

        System.out.println ("What is the second name? ");
        name2 = scan.next();

        message = scan.nextLine();

        System.out.println ("The second name is: \"" + name2 + "\"");
        System.out.println("The balance for this acoount is:" +balance);

        System.out.println ("What is the third name? ");
        name3 = …

>>

public Account consolidate(Account account1, Account account2)
{
       Account accountSum;
      accountSum.balance = account1.getBalance() + account2.getBalance();

   //make account1 and account close()
}

See how that works. Break down the question, and it becomes simpler.
So you need to sum the balance, and close account1 and account2.
By the way, You should make account1 and account2 = null when its closed.

Ok this looks better. For some reason it doesn't think accountSum has been initialized so my program won't run :(.
Here's what my program looks like so far.

1)You should always post error you getting
2)Line 93 if statement is with capital "i"
3)You are missing brackets for your first if statement on line 92
4)Line 95 is not a Java expression. Haven't you been given rules about consolidation?

Is there a particular program that you know of that gives good error codes? I use a combination of Jgrasp and netbeans. Thank you for the figuring out the "I" and brackets.
Could you explain the consolidation rules please. I really don't understand them.

Could anyone tell me what is wrong this code please. I'm trying to do this.
Add a static method Account consolidate(Account acct1, Account acct2) to your Account class that creates a new account whose balance is the sum of the balances in acct1 and acct2 and closes acct1 and acct2. The new account should be returned. Two important rules of consolidation:

Try using netbeans. There are WAY to many mistakes for me to even try to help right now. I counted 11 big mistakes. Let netbeans guide you through fixing all of the big mistakes.

Done. Sorry for the late reply.

Thx a lot masijade. I finally got it ;). Can you please explain why that works? I would like to learn. I would have never of figured that out on my own. My knowledge of java is fairly limited.

I really don't understand what you are saying. How would I initialize "phrase" if i put

while (!phrase.equals("quit")) {

so soon? I'm really new with java so please be kind to me.

Wrap the thing from that point on in a while (!phrase.equals("quit")) { loop.

Where would I place this? while (!phrase.equals("quit")) { If I do it before

length = phrase.length();

it won't run because I haven't initialized "phrase". If I place it after the

length = phrase.length();

, one of two things happens depending on where I place my "}". Option one at the end is it causes an infinite loop or option two if I place the "}" sooner is it does nothing.

Right now my code runs just the way I want it to. I would like the

Enter a sentence or phrase

part to continue until the user enters "quit". I would like to use a while statement. Every way I have tried to enter phrase not equal to "quit" has not worked. Do I need to declare "quit" somewhere or what? Any help would be greatly appreciated.
