I know the "need to ask the user the name of the friend you want to delete, then search the list to find where that friend is and then remove it" I don't know how to do that part...

I'm suppose to do this using sorting algorithm..so it asks to creat a friends database application that maintains a file of friend objects that contain names, telephone numberrs, and email...

It is urgent, because I don't want to start worrying on the day before its due and be like "i don't know where to start". I've started it... but i'm not gonna post it yet because there are still some...

Okay, i haven't started coding yet...but can you tell me the code how i can prompt the user to enter names, and than put them in alphabetical order and outputs them using sorting, thats it. thanks

Hi, I've read the rules for this website and i'm aware that we should not expect people to do our homework. But I really need help on this program.. and I'm not sure how to start it, and it's last...

I did try clicking it... duh.
It still doesn't work, it gives another link about the downloads. and i redled a few times..

what do you mean support link? The site i downloaded from is the DrJava website, drjava.org

hi, I've recently downloaded Java on my computer I think I downloaded the "windows app" one. When I try to launch drjava, this errors pops up and it says:
An error occurred in Dr Java: ...

Yea I've tried that also... but than it gives me a bunch of errors in red...
I made the textfiles thought, dunno why it says cannot find the file..


> java MergeFiles...

This program is suppose to merge the two files by taking one element at a time from each, and the third file should contain the numbers from both file from lowest to highest.

Data1: 11 25 36 45...

I'm supposed to merge a ordered data of two files into a third file, keeping the data in order. I'm suppose to create a MergeFiles application that merges the integers ordered from low to high in two...

Does someone have the solution for this?
I know this isn't homework serice
I have no idea where to start off.......
I don't want a game of life applet, just simple codes that can compile and...

oh.. oops...

I've got the codes all done;
so its looks like this:

public class RightTriangle {

public static void main(String[] args) {
Triangle shape = new Triangle();

...

So basically like just copy all the code that setBase had, and put it in with height? I don't mean replacing it I need the two methods. But when I put them together like im pretty much repeating the...

I got the first part correct but how do I put the get height into the second part? Like would I just repeat everything the base did.. like "private double height" " public void setHeight " etc...
...

oh.. How do i fix it?
I copied this example from the textbook.... so im not sure how to fix it.

It keeps highlighting the line "super(r);" I can't find whats wrong with it.... The Error says: 1 error found:
File: C:\Documents and Settings\HP_Administrator\My Documents\Anna - java\Disk.java ...

oh ok, I got now.. got it to output.
So it's like instead of running the constructor file(circle) run the actual code program instead.. k thx. I'll mark the other one solve too but I can't find...

What do u mean?
Like save it as that name?

oh... i see. I make another thread, its not about disk but this time I typed the code and the constructor (if thats what its called) the two files are in same pack. but it gives this error: Static...

I copied this code from the textbook, so the code should have no mistake? I typed the contructor file(I think thats what its called) and the actual codes. So the code looks like this:

public...

Oh i only copy that one part.....
Is that why its probably not working?
I need 2 files to make this program work?

I have dled the JDK.
Now I have Jdk and Drjava.
But now when I try to run this program there like like 14 errors.......
I don't get it..

oh, thats probably why.... I only dled the Dr java. Ima dl the JDK then

Yea it is. accept on the top bar it says C://document and settings\HP_adminstrator\MyDocuments\TestDisk.java.. and it doesn't just say testDisk.java

How come this program doesn't run?
Well.. not just this program, all my other ones.
There are no mistakes, I wrote the code as this textbook says but its not running and its giving this error (on...

Okay thanks.
Would I need to indent all the codes below after I do the while loop? or just keep it the same?

I'm a newb in Java.
how do I make the loop stop when the user enters 0.
Is the codes right so far?
I can't seem to run it, theres 1 error saying (no source location)


The output is suppose...

hey thanks, but do you know how I can make it so when the user types 'break' it will exit instead of enter to exit

the topic is writing/reading text files, but i got this simple question. how do i make this program so it will look like this: http://i39.tinypic.com/5554wi.jpg i can't figure it out.

- to make...

Hi all. I'm making a program about 'reading and writing text files'
The assignment I have to do is suppose to look like this: http://i39.tinypic.com/5554wi.jpg

But I can't figure it how to...

I've tried yours. It had a error... Why don't you use the one I showed you. I modified it. Instead of entering yes or no, i changed it to 1 or 2. Is that better?

import random

def dieroll():
...

Here is my way of doing it:

import random

def dieroll():
user_input = int(raw_input("How many random numbers do you want?\n"))
for each in xrange(user_input):
randomnumber =...

yea, this is long.. but how do i make this repeat?
At the end it's suppose to ask "do you want to do this again, y for yes, n for no" where yes is repeat from the beginning and no is exit. I think...

ahhhhhh I seee.... thanks!

lol, wow nice. Yours so much smaller than mine.

oh.. yea.. i get it .
Instead of using the 'if else elif' statement you just did the "answer=__" while answer thing. Thanks alot.

This is program i made (basic mash);
I want to make it so that the program will ask if you want to repeat it again. "n" = exit. and anything else makes it repeat.....can someone help me? I'm not...
