How to print the content of LinkedList int[] and LinkedList LinkedList ?

Hi guys, its been a long time since i posted here, and now im coming back to programming using java. My problem is, how can i print the content of the list?
Example:
LinkedList<int[]> list = new LinkedList<int[]>;
int[] input = {1,2,3,4,5};
int[] input2 = {2,32,43,54,65};
list.add(input);
list.add(input2);
how can i print all the content of the linkedlist?
Please help me..I know its a dumb question but i really dunno how.
here is the code:

Here's the funnest, mabye clearest way you could do it: Use 2 Mappers
package tjacobs.util;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import tjacobs.Arrays;
public class Mapper <T>{
     public static interface MappedFunc<T> {
          void map(T value);
     public Mapper(T[] vals, MappedFunc<T> function) {
          this (new Arrays.ArrayIterator<T>(vals), function);
     public Mapper(Iterator<T> iterator, MappedFunc<T> function) {
          while (iterator.hasNext()) {
               function.map(iterator.next());
     public static void main(String[] args) {
          String[] s = new String[] {"a","b", "c", "abc", "ab"};
          MappedFunc<String> func = new MappedFunc<String>() {
               public void map(String s) {
                    if (s.toLowerCase().startsWith("a")) {
                         System.out.println(s);
          Mapper m = new Mapper(s, func);
}

Urgent: how to print the contents displayed in JTextPane

hi all,
i've a problem printing the contents typed in styled format in JTextPane, when i print the contents nothing is printed. can anyone tell how can i print the contents typed in styled format or so. the code for implementing the print is given below.
class ContentsArea extends JTextPane implements Pritable {
   public int print(Graphics g, PageFormat pf, int pi) throws PrinterException {
      if (pi >= 1) {
         return Printable.NO_SUCH_PAGE;
      Graphics2D g2d = (Graphics2D) g;
      g2d.translate(pf.getImageableX(), pf.getImageableY());
      g2d.translate(pf.getImageableWidth() / 2,
                      pf.getImageableHeight() / 2);
      Dimension d = getSize();
      double scale = Math.min(pf.getImageableWidth() / d.width,
                                pf.getImageableHeight() / d.height);
      if (scale < 1.0) {
          g2d.scale(scale, scale);
      g2d.translate(-d.width / 2.0, -d.height / 2.0);
      return Printable.PAGE_EXISTS;
}i'd be grateful to all ppl who helps me.

What's the exact problem? The printer printing a blank sheet or the printer not doing anything at all? First make sure in the main program you've got something along the lines of...
import java.awt.print.*;
PrinterJob printerJob = PrinterJob.getPrinterJob();
PageFormat pageFormat = printerJob.defaultPage();
if(!printerJob.printDialog()) return; //not essential but lets the user tweak printer setup
pageFormat = printerJob.pageDialog(pageFormat); //ditto
printerJob.setPrintable(this, pageFormat);
print(...);
The above code should go in an ActionListener, triggered when the user hits a print button or menuitem. I'm guessing you already have something similar set up.
Then your print(...) method should be similar to
public int print(Graphics g, PageFormat pageFormat, int pageIndex)
     if(pageIndex>0) return NO_SUCH_PAGE;
     Graphics2D gg = (Graphics2D)g;
     gg.draw(whatever's going to be printed);
     return PAGE_EXISTS;
Which it is, although yours has clever scaling stuff built in ) The only thing you're not doing is rendering the actual content.
So if you want the contents of the textpane, it'd make sense to use something like g.drawString(myTextPane.getContents()); in the print method. Note it's g and not g2d, since Graphics2D has more complicated text handling routines.
I'm no expert tho )

How to print the contents of doubly-Linked List

Hi
I have a DLList consists of header , trailer and 10 linked nodes in between
Is there a simple way to print the contents ie "the elements"
of the list
thanks

In general you should write an iterator for every linked data structure for fast traversal. I'm guessing you're writing your own DLL for an assignment because one normally uses the LinkedList structure that is included in the api. Anyway, here is an example of how the iterator is implemented for a double linked list:

How to save the content of a JTextArea into a txt file?

Hi, I want to save the content of a JTextArea into a txt file line by line. Here is part of my code(catch IOException part is omitted):
String s = textArea.getText();
File file = new File("file.txt");
BufferedWriter bw = new BufferedWriter(new FileWriter(file));
bw.write(s);
bw.close();
But I found in the file all is binary code instead of text, any people can help me?
Thanks in advance

I can see text in the file now, but the problem is
when I write three lines in textarea, for example
111
222
333
then I open the txt file with notepad, it is
111222333
How to save them line by line? Use a PrintWriter. It lets you write lines (it's the same class as System.out).

How to print the content of a DynPro Window?

Hello,
Is there any DynPro (Or SAP) package that can print the current window content? If yes, can anyone please show me a code example?
Roy

Roy,
Printing content of the window is almost always not a solution. Personally, I hate sites where articles are not available in printer-friendly format (either via separate page or CSS with media type printer).
With WebDynpro it is even worse -- does end user really expect all this buttons, complex tables, combo boxes etc.?
My advise is to either:
1. Create Adobe PDF for user to download and print
2. Create printer-friendly HTML and open it in external window
3. Create MS Excel file to download.
First and third options are well documented in SDN docs / tutorials, the second option is very easy to implement: take my code for transforming context tree to XML converting context-tree to xml? and apply necessary XSLT template. This way you may get HTML output in printer friendly form.

How to print the content in Reverse which is read from the file

i have written a program to display the content of the file using files concept. now the task is how to display it in reverse order i.e from last to first which is read from the file.

If it will all fit in memory read the file as you are doing now appending everything into a StringBuilder. Then use the reverse() method of that class to obtain your output.

How to print the content of a text edit ?

Hi to all,
I have a view with a text edit and I want to print its content. I created a button and I want to print text edit content pressing this button. How can I do? Which java code I have to insert in that button?
thanks a lot,
Antonio

Antonio,
Sadly, there is no way to do it directly. Even in plain HTML application it is impossible to print text of UI control (<textarea> in this case).
So you have to open new browser window containing entered text and let user print text himself. Or invoke window.print() on document load event.

How to print the contents(data) of an Applet

My problem:
I have an html page that is split up into several frames. One of these frames is actually an applet that has a table of data that I retrieve from a database. I want to be able to print out ALL of the data from the applet. I added a button to one of the frames(not the Applet frame) to print. For the button.onClick event, I created a function called "print". That function's code right now is Applet.print(Graphics), but when I try to click the button I get a Runtime Error that says "'Applet' is undefined". Am I even close to getting this working?? How would I define the 'Applet' in the frame that I have the Print button in?

Hi pargol4
I have problem retrieving data from the database by an applet that needs new data in one second interval. The communication between the applet and the database is too diffucult for me.
All I have is just two files, one is the applet DrawMe.java and the other is MyData.java to communicate with the database. If I need to communicate with the database from the applet, where I have to put my code like InputBuffer and OutputBuffer, is the run() method of the applet the right place for it? ... do you have a code bit to illustrate that for me?
Thanks in advance ... Carina

How to print the contents of the table in new page?

Hi,
I want to print my table contents in the next page by clicking on a button. ie., kind of a print preview. I'm using netweaver2004s.
Thanks & Regards,
Suresh

Hi,
1)Create a new View, map the context node which is bound to the table to the context of this view.
2) Iterate throught the element and print them to the screen.
3) Embed this view to a window.
4) on click of the button open the newly created window.
Code to iterate through the nodes
for(int x=0; x< wdContext.nodeTest().size(); x++) // Replace nodeTest with yours
ITestElement nodeElement = wdContext.nodeTest().getElementAt(x);
nodeElement.getAttribute("TestAttribute"); //Replace with yours
nodeElement.getAttribute("TestAttribute"); //Replace with yours
