How to get input from keyboard scanner into an array

This is probably a very basic question but I'm very new to java..
My task is to reverse a string of five digits which have been entered using keyboard scanner.
E.g. - Entered number - 45896
Output - 69854
I used the StringBuffer(inputString).reverse() command for this, but i need a more basic method to do this.
I thought of defining an array of 5
int[] array = new int [5];
and then using,
Scanner scan = new Scanner(System.in);
to enter the numbers. But I can't figure out how to get the five input numbers into the array.
If I can do this I can print the array in reverse order to get my result.
Any other simple method is also welcome.

Hey thanks for the quick reply,
But how can I assign the whole five digit number into the array at once without asking to enter numbers separately?
E.g. - if entered number is 65789
Assign digits into positions,
anArray [0] = 6;
anArray [1] = 5;
anArray [2] = 7;
anArray [3] = 8;
anArray [4] = 9;
I'm really sorry but I am very new to the whole subject.

  • How to read input from handheld scanner on a keyboard port

    Hi everybody,
    i have an application that should read input from a scanner.
    If i use a jTextField to input scanned data it works fine.
    the problem is that i don't want to use any text component to input data into it.
    And if i set the jtextField not visible then the focus sustem doesnt work.
    I tried to read a buffered input stream from System.in but it doesnt work.
    If the scanner was installed on a serial port i could use javax.comm to monitor it.
    But unfortunately i must use the keyboard wedge thing...
    Do you have any ideas?
    Thank you in advance

  • How to Get Input from Command Prompt?

    How can i get input from command prompt like
    C:\
    or linux ?
    (Here's what I use now)
    BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
    String line;
    Whlie((line=in.readLine())!= null)
    { System.out.prinln( line) ; }
    IS THERE A BETTER WAY?

    The main method within a java class accepts command line input through a String array.
    In this example args is the String array. You can access the parameters as args[0] for the first parameter, args[1] for the second parameter, etc....
    The usage for the example below would be :
    c:\EDIFormat file1 file2
    Where args[0] would equal file1 and args[1] would equal file2.
    public class EDIFormat {
    public static void main(String[] args) {
              if (args.length < 0) {
                   System.out.println("No Parameters supplied. Exiting....");
                   // open input and output files
                   EDIFiles(args[0], args[1]);
    Hope that helps!

    Below is my code. Currently it gets the input from the textbox "Date" and places it into a textfile using "getText"
    How do i get the input from a radio button?
    i think getselected only works on JLists.
    String a = bookNo.getText();
              out = new PrintWriter(new FileOutputStream("" + a +".txt"));
    out.println("Date: " + tDate.getText());
    out.close();
    catch(IOException ex)
    System.out.println("Error");
    Your help is appreciated

    Sorry, here's my code. The point of the system is to write information from the page, onto the textfile named "something.txt"
    public void write() {
    String fullfile = "something.txt";
    try {
    BufferedWriter out = new BufferedWriter(new FileWriter(fullfile));
    out.write("");
    out.write("HOLIDAY BOOKING SYSTE,");
    out.write("");
    out.write("SECTION 4.0 DESITNATION");
    out.write("");
    out.write("Holiday Destination: " + list.getSelectedValue());
    out.write("Duration of holiday: ");
    out.write("");
    out.write("SECTION 5.0 TRAVEL RESERVATION DETAILS");
    out.write("Airport for depature and return");
    out.write("Depature Date: " + txtDateD.getText());

    out.write("Arrival Time: " + txtDateA.getText());
    out.write("Holiday Destination: " + txtbookingno.getText());
    out.write("Customer Booking Information");
    out.close();
    } catch (IOException f) {
    //end of file writer
    The code below is for the radio buttons, The choice is to either pay for an "Economic" ticket, or a "First Class" ticket. If a customer selects the economic ticket radio button, what line of coding do i add to the write method above, to show "Economic ticket"
    Also i ran into another slight problem, theres a textbox called "Fine" in another form called "page1", how do i call it's value i.e. what line of code do i place for it in the method above?

  • I'm dumb, can't figure how to get playlist from itunes library into my itou

    Ok, I have looked and looked and did search. I want to copy a few playlists from my itunes library into my itouch. I was told they would transfer when I synched, they didn't. Drag and drop does not do the job. What am I missing? I am sure something very very simple. HELP. I do NOT want to do the playlist again in my itouch from scratch, as I have almost 1,000 songs to search through.
    There has got to be an easier way.

    "Synch" is the process whereby files get copied from the iTunes library to the iPod. If your playlists did not copy, what actually did happen when you synched?

  • How to get input from BARCODE Reader

    using oracle forms builder...........in form text box

    Yes I actually used such a reader way back with forms 2.0.
    It connects into the keyboard lead so as far as the form is concerned it is exactly the same as typed input. Such readers can also be programmed to send a <return> at the end of the string to fire validation and move to the next field. The keyboard emulation method is also ideal when an unreadable barcode is encountered as the operator can just take over and type it in manually.
