Print out vector

Hi
Does anyone know how I could print out the contents of a vector in a list in a message dialogue box.
Thanks
Jon

Yes. Iterate through the contents of the Vector appending the return value of their toString() method to a StringBuffer & then set this as the text of the dialog.
Oh, you wanted a code sample? No time.

How do I print out the attributes of objects from a Vector? Help !

Dear Java People,
I have created a video store with a video class.I created a vector to hold the videos and put 3 objects in the vector.
How do I print out the attributes of each object in the vector ?
Below is the driver and Video class
Thank you in advance
Norman
import java.util.*;
public class TryVideo
public static void main(String[] args)
Vector videoVector = new Vector();
Video storeVideo1 = new Video(1,"Soap Opera", 20);
Video storeVideo2 = new Video(2,"Action Packed Movie",25);
Video storeVideo3 = new Video(3,"Good Drama", 10);
videoVector.add(storeVideo1);
videoVector.add(storeVideo2);
videoVector.add(storeVideo3);
Iterator i = videoVector.interator();
while(i.hasNext())
System.out.println(getVideoName() + getVideoID() + getVideoQuantity());
import java.util.*;
public class Video
public final static int RENT_PRICE = 3;
public final static int PURCHASE_PRICE = 20;
private int videoID;
private String videoName;

public Video(int videoID, String videoName, int videoQuantity)
this.videoID = videoID;
this.videoName = videoName;
this.videoQuantity = videoQuantity;
public int getVideoID()
return videoID;
public String getVideoName()
return videoName;
public int getVideoQuantity()
return videoQuantity;
}

Dear Bri81,
Thank you for your reply.
I tried the coding as you suggested
while(i.hasNext())
System.out.println( i.next() );
but the error message reads:

Do not know how big or small items in image will be after being printed out

I have just started using photoshop to develop some designs that are meant to be printed on fabric. And then sewn into dresses
While I know how to change the size and scale of the image and canvas. I can not tell how big or small the objects or different elements in the pattern will be when printed out.
For example if I want to have a certain part of the pattern appear on the shoulder of a dress and another on the hem, how do I ensure that they are printed at the right size and in the right place.
I tried printing out one pattern on a meter of fabric and it turn out that it was too big and most of the design will be cut in the process of making the dress. I have no way to determine the dimensions.
Is there a way where I can place a dress outline over an image to check it out or size the individual items inside?
Thank you

can place a dress outline over an image to check it out or size the individual items inside?
Do you have the cut in digital form (vector or pixels)?

Printing problem when printing a vector based program generated pdf file

Hi,
I bought a software which comes with a camera auto-focus calibration chart. The manufacturer mentioned that this chart is generated by a vector base program so customers can ajust the size of chart without any problem. The chart file is in pdf format.
When I use my Photoshop CS5 (on Windows 7) to print it from my Epson 2200 inkject printer, it only print the vector part without filling up the inside of the vectors enclosed area to black. Even the words in the footer are printed the vectors only (without fillup the word with black).
I'd appreciate if anyone can help pointing out what's the cause.
Thanks,
Eric

I have tried to print with pdf app as well. Same result.
I found the solution yesterday while searching on line. Ended up it's the Epson 2200 driver bug. I was using Matte Black and the driver thought it is not compatible with Epson Premium Matte paper, so it did not print with that black ink. Change back to Photo Black ink solved it.
So case resolved. Thanks
Eric

Scope of a non-static method printing a vector of objects

Hello everyone,
I'm new to using the java.util.Vector package. I wanted to create a print out of all the objects of class "Student" that I created within a "students" vector. My problem is that scope is causing a compile error when calling the print method acting on the students vector. Anybody got any ideas? Further to this I'd like to keep my printVec() generic enough so that I can create a class "Teachers" and a "teachers" array and make the the printVec() method able to print both, ie;
teachers.printVec()
students.printVec()My code is below;
import java.io.*;
import java.lang.*;
import java.util.*;
class Example {
   public static void main(String[] args){
      Vector<Student> students = new Vector<Student>();
      students.addElement(new Student("Billy"));
      students.addElement(new Student("Ryan"));
      students.addElement(new Student("William"));
      students.addElement(new Student("Jason"));
      //the below print algorithm works...
      for(int i=0;i<students.size();i++)
         System.out.println(i+" "+students.elementAt(i).getName());
         //however i can't get this following one to work...
//       students.printVec();
         //uncomment above line
   public void printVec(){
//      for(int i=0;i<students.size();i++)//uncomment these lines
//         System.out.println(i+" "+students.elementAt(i).getName());//uncomment these lines
        //uncomment above two lines
class Student{
   //constructors
   public Student(String name){
      this.name = name;
      this.subjectNumber = -1;
      this.tutorialNumber = -1;
   //methods
   public String getName(){
      return name;
   //fields
   private String name;
   private int subjectNumber;
   private int tutorialNumber;
}

You should use an Iterator, not get(). And youshould
prefer ArrayList over Vector.Why are you telling me this? I know this already... I
was reusing the OP's way so that he/she/it could see
it done his/her/its way.I have no way of knowing what you do or don't know. I only saw crap code, so I corrected it.
>
That won't work if more than one student has thesame
name, and it's a very counterintuitive way to
approach the problem.Um... yes, it will work if more than one student has
the same name. It will not work if students in the
Vector share memory. It searches for memory, not the
name.Actually, we're both wrong.
If Student overrides equals to be based on name, then it won't work as I described. If not, then it will work.
It only looks at "memory" if Student does not override equals.
I didn't think that there would be a problem with
memory, but if there is, simply add a counter:????
What are you talking about?
public static void printVec(Vector<Student> students)
int count = 0;
for (Student s : students) {
System.out.println((count++) + " " +
+ " " + s.getName());
}That's the right way to do it, but that has nothing to do with "a problem with memory."

Printing a Vector to a JTextArea

I'm having major problems with my project.
I can't get the information retrieved from a database to print to a JTable even though i've looked at so many different tutorials.
I ended up printing the information to a JTextArea for now but i'm having problems printing a vector to the TextArea.
     Vector columnNames = new Vector();
                      Vector data = new Vector();
                      Vector cache;
                      cache = new Vector();
                      int columns;
                      String[] headers;
                         try {
                              Class.forName("com.mysql.jdbc.Driver");
                              Connection con = DriverManager.getConnection (Url);
                              Statement stmt = con.createStatement();
                              ResultSet rs = stmt.executeQuery(query);
                              ResultSetMetaData md = rs.getMetaData();
                              columns = md.getColumnCount();
                              //read names of columns
                             for (int i = 1; i <= columns; i++)
                                 columnNames.addElement( md.getColumnName(i) );
                             System.err.println(columnNames);
                             String rowdatatotal = columnNames + "\n" + "\n";
                             while (rs.next())
                                  Vector row = new Vector(columns);
                                  for (int i = 1; i <= columns; i++)
                                       row.addElement( rs.getObject(i));
                                            sqloutputArea.setText (rowdatatotal + "\n");
                                  System.out.println(row);
                            }is there a way around this?
Thank you for your time

I have tried to use toString() by doing the following.
while (rs.next())
                                 row = new Vector(columns);
                                  for (int i = 1; i <= columns; i++)
                                       row.addElement( rs.getObject(i));
                                            sqloutputArea.setText (rowdatatotal + "\n");
                                  row.toString();
                                    sqloutputArea.setText (row);Is there an alternative to addElement but for strings?
I was wondering if i changed the vectors to Strings and substituted the addElement, it might work?

PDFs print out darker in Windows Reader 9.0 than Mac Reader 9.0, also Win Reader 9.0 darker than 8.x

Hi,
Using Adobe Reader 8.1.2 for Mac OS X and 8.* for Windows, my PDFs printed out identically for both platforms.
However, after I upgraded Windows Adobe Reader from 8 to 9.0.0, it prints out the PDFs significantly darker than before, whereas when I upgraded the OS X Adobe Reader from 8.1.2 to 9.0.0, the print outs did not get any darker.
Now they are both on v9.0.0, Windows printouts are significantly darker than the OS X printouts, using the same PDF file, printer, etc.
Any idea what's going on here? Is there some of weird gamma correction-type thing going on - although I thought that only affected monitor displays, not print outs? Or should I report it as a bug?
The PDF I am testing is here:
http://egalo.com/guitar-fretboard-visualisation-sheet.pdf
I also tried printing it out from other PDF viewers - Preview.app on OS X and Foxit Reader on Windows - and they both print out normally i.e. the same as Adobe Reader 8.* for all platforms, and 9.0 for OS X - definitely not as dark as Adobe Reader 9.0.0 for Windows.
I'm running OS X 10.5.4 and Windows XP Professional as a VM using Parallels.
Needless to say, I want to be able to generate PDFs that have the same darkness regardless which PDF viewer or OS platform is being used to print it out.
Thanks, Xen
[Edited to improve clarity]

Thanks Michael,
The file that I have sent her has both vector and raster graphics in it, and they were apparently printing fine. It just seems to be text that's not printing correctly.

Print out Forte Arrays

Greetings All:
I'd like to know if anyone has had any experience printing out
Forte Arrays[screen tables] from the Forte Window it exists in.
Example:
A Forte window exists that contains Forte Arrays. I
want an option to either select from the pulldown
FILE menu or select a button which will automatically
print out the contents of that Forte Array.
Has anyone tried to resolve this kind of problem before?
Regards,

System.out.println(in); }
catch(IOException e){
e.printStackTrace();
System.out.print("Enter line:");
int index = Integer.parseInt(fname);
System.out.println(.get(index -1)); //probs here
assuming user enter say 4
say
index=4;
then
System.out.println(v.elementAt(index-1));
hope this helps

How do I print out the results of a "search" or "find"?

I used ical's "find" or "search" field to look up all calendar entries for a project I was working on. How do I print out this result? This is basically the information in the lower right box after you do a search.

Dear Bri81,
Thank you for your reply.
I tried the coding as you suggested
while(i.hasNext())
System.out.println( i.next() );
but the error message reads:
"CD.java": Error #: 354 : incompatible types; found: void, required: java.lang.String at line 35
Your help is appreciated

How can I print out the file directory?

Years ago, I could print out a list of files in a folder from the finder window. Is there now a workaround utility to do that? I don't want to use screen shots, as the directory is too long and would require several screen shots. thx.

How can I print out the graph I need only, without the controls and indicators?

I'm doing some programming in LABVIEW. I need to print out only the graph, without the buttons, controls, indicators. I tried to look for such a function in LABVIEW, but in vain. How can I achieve the result I expect in my programming?

Hi Fenny,
you should use the report generation functions to create a report containing your graph image and print it.
Take a look at the Sample Test Report.vi you find in the report examples of LV.
Just look at the part of the diagram where it is used Append Control Image to report.vi (in the center of the report functions chain); a graph reference is wired to the Ctrl reference input ( to create a reference of your graph right click on it and select create reference).
Let me know if you need more help,
Alberto

How can I print out the contents of my hardrive

I have a hardrive with about 200 video clips and need to print the titles for cross refrerencing. I was just going to "grab" screenshots but this will take about ten sheets of paper. How can I print out a list of all the files on the drive?

I tried this Finder drag method & discovered that it is very important to set the blank TextEdit document to plain text before the drag (from the format menu or with Cmd-shift-t). If you don't, TextEdit attempts to load the content of the files!
Once I discovered this, I tried the method with Find (Cmd-F) results & it works for that, too. This means that by choosing the right combination of search location(s) & search criteria, you can extend the method to filter the list to just about any files you want, which could be very handy.
For instance, set the "Kind" criteria to "QuickTime Movie" & location to "Computer" & you get a list of every QT movie. Or set the search location to the folder containing the movies of interest & you get all of them, including ones in subfolders. You could also use the 'date created' or other search criteria to filter the list to a specific subset of movies (or whatever).
If you need to do this often, you could create one or more 'Smart Folders' with the criteria preloaded for each search.
The only drawback I see for either Finder based method is the full path one. If you are getting results from just one or a few folders, Find & Replace can delete any of the path name fairly easily, but it becomes a chore if there are a lot of different ones. Some other text editor, like TexEdit Pro, that supports grep searches would be handy here, but since I'm not up to speed on grep, someone else will have to explain how to use it for this, if they want.
