What the user enters in the JTextField is stored to the variable fine, I out put that variable just a couple of lines later. But when I test it in the indexOf() or contains() methods, it does not...

Hey,
I am trying to find a way to limit how many characters a user can enter into a JTextField.
Does anyone know how to do this?
Thanks!

Hello,
I am having problems with indexOf() and contains() they work if I put letters in the code to test, but I want it to test what the user enters. And that is not working. The user enters a...

I wrote some of it. I did use a debugger, and still couldn't figure it out. I got it down to shortpath[0] is being set to 0 in the updatepaths() method though.

Hey,
So I am having this problem with this code. I think the problem is that shortpath[0].distance is being set to 0, and so never going into the if statement of updatepaths() therefore messing up...

NOTE:This is a correction from my previous post.

I got it partly figured out, top was being set to NULL in the print() method. So I made it so top won't be NULL anymore.

But I'm still having a problem, I think because when I addToQueue in merge...

Hello,
I need to make this program sort the numbers entered with merge sort then print them. I am having trouble calling merge sort and getting it to print.

Here is the code:

#include...

oh your right! Sorry, I don't know my problem this week, I keep forgetting stuff like that! I usually remember to do that and put mergeSort:: in front of all of the methods!

Never mind, taking out the struct Item worked.
But now, you said that i need to change Queue sort to mergeSort sort, i did that and then an error was comming up in queue saying that addToQueue can...

So about the struct, should I completely take the struct out of mergeSort? I tried doing, and changed everything in mergeSort to Data that and it caused errors. Then I tried making Item derive...

Hello,
I am having trouble understanding linked lists. I have to make this program that takes input, stores it to a queue, outputs that input, then sorts it using mergesort and outputs it again. ...

I will check that out, thanks!

Hello,

It is suposed to print the char, not the int.

Hey, So I got this program all working except some of the output is weird pictures instead of letters. The first time it outputs it works fine, but after that it only partly works.

Here's the...

Well, I think my main problem is getting it to work with two different queue objects...it works with just one.

Hello, I have to make this program that has two queue's. It takes input from a file, and each line in the file has a number and character. If the number is a one, the character is stored in the...

ok, thanks!

I added an integer after the = (the teacher said we could) and it worked.

oh wow that works! Why does that keep it from printing before? Like I thought since I have cout << in the while loop, it would print each time it goes through. Is it going through the whole file...

Here are the contents of the file:
R 3
T 5
W 1
A 4
* 3
M 5
B 1
E 1
F 2

Hey, I am having trouble with the file I/O part of this program. It seems to start at the end of the files contents and not go into the while loop.

#include <iostream>...

Nevermind, I figured it out. Thanks for all of your help!

Hey, have gone through the whole code looking for what could be causing the problem and have found nothing.

Thanks everyone! All of your comments actually did help me!

Ya, I was looking for a missing or extra one yesterday but couldnt find it. I guess I'll keep looking. Or I'm hopping he found it today at school.

Ok, let me explain: I started tutoring him last thursday, while he was in middle of this program. That is why the code is formatted badly, the comments arent good, and other various problems you...
