Java program help

java-programmer, Java program help Hello everyone, I need your help.. can you check why did i commit an
error on the n=System.read("enter numer:"); part...? Thanks in
advance...
By the way, the program will run as follows:
the user will input a number, and the program will generate the
fibonacci series based on the number. if example user input is 4,
there should be four series of fibonacci...:)

public class fibonacci
{

public static void main(String args[])
{
int prev1 = 1, prev2 = 1, current = 1;int n;
n = System.read("enter number: ");
for (int i = 3; i <= n; i++)
{
current += prev2;
prev2 = prev1;
prev1 = current;
System.out.println(" " + current);
}

}
}

java-programmer >> Java program help Maybe because a method called int System.read(String)
I think you have to use the methods of the InputStream System.in.
You can do something like this:
java.io.BufferedReader br = new java.io.BufferedReader(new
java.io.InputStreamReader(System.in));
int n = Integer.parseInt(br.readLine());

How about doing your homework yourself? Sheesh, the way you copied
your assignment word-for-word doesn't make it look like you intend to
bother trying it yourself at all. What do you think you're in school
for, anyway?

thankyou for the pointer. luckily i have subscribed to c.l.j.help
already. can i ask one question of you? what is the charter of
c.l.j.programmer? i would have thought that if you had a java
programming question that this might be an apporopriate place to start?
correct me if i'm wrong, and i know that you will :-)

The charter for .programmer is:

This unmoderated group is for problems and discussion relating to
Java as a language, programming in general and the application of
libraries and APIs not covered under other groups.

If traffic is high enough, this group may later be split
functionally. In the meantime, posts specific to a class or package
should include its name at the beginning of the title, for example,
[awt], [sun.net], etc., to facilitate easy filtering.

That's all academic, though. There is no mechanism to update a charter
for a Big-12 newsgroup, and as a result charters rarely describe the
actual usage of groups. Lurking is encouraged to determine that. For
example, .help is quite frequently used for involved programming
questions, despite its charter that encourages mostly setup/install
questions and only the most simple of programming problems.

There's currently a vague understanding that "beginner" questions go to
.help and "advanced" questions go to .programmer. Nevertheless, there's
never really been a determined effort in the past to sort traffic to the
correct groups. Andrew has attempted to start such an effort in the
past year or so, and a few other people have jumped on the bandwagon.
I'm of the opinion that it does more harm than good, especially when (as
has occasionally been the case recently) it causes people to feel
justified in being rude to new posters.

Pretty much what Chris said, ..but since I have an URL.
<http://www.physci.org/codes/javafaq.jsp#groups>

Note the caveats that Chris added. Ultimately a group
is shaped by the contributors.

java-programmer >> Java program help Hi, I have to write the following program for class...and I have no idea
where to start
if anyone would be so kind as to point me in the right direction (or write
the program) i would be very appreciative

1. Write a class named Pupil that implements Comparable. It has four
instance variables of type String and double (Name, testl, test2, test3, and
average). The constructor must input the test scores from the user, and call
the computeAverage method to initialize the instance variable, average. In
addition, the class must have getters for each instance variable. It must
also have a private helper method called computeAverage that returns the
average of all three test scores. And a compareTo method that compares two
students. It must work like all compareTo methods such that it takes in an
Object parameter and returns 1 if the object that called it is greater
returns -1 if they are equal, it returns 0.
2. Create a TestPupil class (must put import Java.lang; at the top) that
prompts the user for the number of students in the class prompts the user to
enter the information about all students in the class and creates a student
object for each pupil. Stores the students in an arrayList and calls the
compareTo method which compares all the students to all the other students in
the class

Thanks

The instructions seem pretty straightforward, so if you
have no idea where to start you must be having pretty serious
trouble with the class. I strongly recommend that you talk
with your professor about the difficulties you're having; you
may need some extra tutoring. Do it now, while the semester
is still young: In the early going your professor may be able
to help you overcome your problems and catch up, but if you
just sit there comprehending nothing and letting the class
wash over you, the professor may not become aware of how far
behind you are until you're so far behind there's no hope.

The professor wants you to learn -- so if you want to
learn, go have that talk. Now!

I see that the "if you want to learn" is not exactly
a tautology.
