How to Save data about 5 computers?

I have a course assignment but im stuck.

this is what I was told.

Use a text file. Save data about 5 computers: HDD size, model name, weight, and screen diagonal. Find a computer with the biggest diagonal.

Help please.

What you have done ?

In starting just create a small program that creates a file and write your name in this file.
Later extend this program to have data as you required.

Thanks

I just can't grasp java yet and this task is a little beyond me, could you write it for me, I could pay.

i paid alot for this course and i really dont want to fail.

Welcome to the Ranch.
What have you tried and where are you stuck?

I think the requirement indicates reading a file and analyzing the data.

The Ranch is NotACodeMill
If you wish to pay for someone else to write your code, there are other sites out there to facilitate this kind of thing.

A friendly tip:
Asking someone to write your code so you can pass is not really a good idea. Wouldn't you rather do it yourself? What will you do when you are stuck with a problem at your job? Pay someone to take care of it for you?
I would suggest, give it your best shot. In case you can't get it, show us your code, tell us what part you are having problems with, and we will pool in to point you in the right direction. Best of luck

Just try this is not very hard, you can do it and we all are here to help you.
If you have paid a lot for this course then make it worth by learning..

Thank you for your replies.

I understand this isn't a codemil and i apologize for asking but I haven't had the time to learn Java as well as id hoped, i just don't have the time.
my mother currently has a spinal disease so she cant walk anywhere so I'm constantly looking after her but trying to stay on top of my assignments.
I just need this one little program so i can give myself more time to learn Java, I don't want to lose my money.

It's just really hard

I am really very sorry to know about your problems, but this type of help is not going to help you actually, this will just make you more dependent.
This is not hard as it seems to be. You just start with it and soon you will find that you are about to complete it.

I'm actually really self reliant, I just can't think at the minute. I have done my last 5 assignments which I could show you but I just need this little bit of help please.
I have to much on my mind at the minute and i have till tomorrow to complete this.

This was my first.

import java.util.Scanner;
import javax.swing.JOptionPane;

public class numberAdding {
	
	static Scanner sc = new Scanner(System.in);
	
	static int m = 77;
	static int l = 50;

public static void main(String[] args) {
		JOptionPane.showMessageDialog(null, "Welcome to Craig's number challenge!");
		System.out.print("What is the answer to 43 + 34: ");
			int f = sc.nextInt();
		if (f == (m)) {
			JOptionPane.showMessageDialog(null, "Congratulations, you got it right!");
			System.err.println("Next question!");
			question2();
		} else {
			System.err.println("Next question!");
			JOptionPane.showMessageDialog(null, "I'm sorry but that was wrong.");
			question3();
		}
	}
	
	public static void question2() {
		System.out.print("What is 25 + 25: ");
			int g = sc.nextInt();
		if (g == (l)) {
			JOptionPane.showMessageDialog(null, "Well done, you got both questions right!");
			System.err.print("The quiz has ended.");
		} else { 
			JOptionPane.showMessageDialog(null, "I'm afraid you got it wrong!");
			System.out.println("You scored 1 out of a possible 2.");
			System.err.print("The quiz has now ended.");
		}
	}
	
	public static void question3() {
		System.out.println("What is 25 + 25: ");
			int c = sc.nextInt();
		if(c == (l)) {
			System.out.print("Congratulations but you scored 1 out of 2.");
		} else {
			System.out.print("Oops, you got both questions wrong. Better luck next time!");
		}
	}
}

This is my most recent.

See Oracle's tutorials about I/O. It's also easy to find examples on the web of reading and writing text files in Java line by line.

I don't hardly understand them concepts, I desperately need this, please can somebody just help me this once. I'll do anything..

Hi,

I found one tutorial to write to text file, you can extend this code for your program.
Let us know if you face any problem.

[Edit]
Search yourself to know how you can read the file once you are done with writing. Later you can write logic to find out the computer with maximum screen size.

Joe, please BeForthrightWhenCrossPostingToOtherSites <-- that's a link
http://www.java-forums.org/new-java/57750-how-save-data-about-5-computers.html

Any more?

It's okay, I'm going to try myself. Thanks for the help but I need to do this myself, I apologize for cross posting and begging.

Ugh. Roseindia sucks balls. Don't take their code and advice for anything but anti-patterns.

1) take a deep breath
2) slow down
3) relax
4) analyze your requirements, and break it apart. write the code a small piece at a time. Compile and test OFTEN - literally, every time you write 2-3 lines, recompile and fix any problems.

"Use a text file. Save data about 5 computers: HDD size, model name, weight, and screen diagonal. Find a computer with the biggest diagonal."

This has several pieces:

1) writing to a file
2) storing data on 5 computers
3) finding the diagonals
4) saving the largest number of a set
5) getting all the information on the computer with the largest diagonal.

So...why are you asking for username and passwords, if the specs don't ask for it? Don't make the project any more complicated than it needs to be.

Whats wrong with roseindia ? If the post is useful then whats the harm to use it and start.

He is not asking for the user name and password in the current program, these are the some of the programs those he previously created..

Yes, they were some of my previous programs that have yet to be implemented.

Okay, I've got my head back on now, I hope I've nearly done this, it's pretty much just basic I/O, I think I got a little dazzled by the test.

Thanks for all the replies.

There are enough blatant errors there that it makes the site not even worth considering, especially in light of the fact that there are far better resources just as readily available.
