I am starting to learn java (from sean greasly :D), and I encountered a problem in this script. Can anyone show me how to fix it?

package helloworld;

import java.util.*;

/**

public class Arrays {

    public static void main(String[] args) { 
        
        int[] studentAge = new int[5];
        Scanner theInput = new Scanner(System.in);
        
        for (int x = 0; x < studentAge.length; x++) {
            System.out.print("Enter age for student " + (x + 1) + ": ");
            studentAge[x] = theInput.nextInt();
        }
        
        System.out.println("The student ages are: ");
        
        for (int x = 0; x < studentAge.length; x++) {
            if (x == studentAge.length) {
                System.out.println(studentAge);
            } else {
                System.out.print(studentAge + ",");
            }            
        }
        
        theInput.close();
    }
    
}

What error are you getting? I see nothing wrong with it.

I think he needs a try-catch clause around his Scanner object methods/declaration. I forget if you need it, but I'm pretty sure it can throw an IOException.

Haha, I didnt either, Jason.

Well, after I start to run it, the script asks me for an input, before anything is appears. Then, if I input anything, it either

a). Terminates and gives a bunch of scanner errors.
b). Continues with the script after 5 inputs, but doesn't allow me to input anything when it asks for the ages.

I probably do need a try catch, but I wouldn't know how to do that :D

Lol @ sean greasley :rolleyes:

Hm, I can't see anything wrong with it.. and no errors for me either.

try using eclipse, its really usefull:)

Im using netbeans. Maybe i should try running it w/ command prompt?

Hm, try that. I suggest eclipse though, pwns netbeans anytime anywhere.

Meh? Whats the difference between the two?

Anyway, I didn't see any errors… But thats me, the newb.

You should probably know that IDEs are user preferred. I'd say Eclipse can lick my grundle because IntelliJ IDEA owns it, but some people wouldn't think so.

Anyways, try using batch scripts to run it; perhaps you'll get different results.

I just use Textpad, I don't like IDE's

If I wanna Jar something I'll do it myself.

Oh, Btw:
if (x == studentAge.length - 1) {
and
studentAge[x]
Since you had studentAge which is an object so print/println would use toString and that would return a hex


EDIT: Oops sorry, I didn't see that this topic was old

thanks :D

Nah, its no problem, no one posts in these forums anyways lol

replace new Scanner(System.in) with this
in = new BufferedReader(new InputStreamReader(System.in));

then call
in.readLine() to get the user to type in something and press enter

I also noticed a little thing in your for loop?

for (int x = 0; x < studentAge.length; x++) {

Im pretty sure you dont want to make x bigger until it is smaller than studentAge.length?

Netbeans rocks.

For (int i = 0; i < 10; i++) does the loop 10 times.
Set/Int Number; WhileCommand, increasecommand

Thats the same as saying

[php]
for x := 0 to Length(StudentAge)-1 do
begin
end;
[/php]

Sorry for double post!!

My bad pl0x
