Saving System.out text into array of Strings
I've got a lot of strings, which are being inputed into System.out
Is it possible to transfer symbols from System.out into array of strings?
Do you mean in real time or after the fact parsing it?
For a realtime solution you may want to look at creating a class that extends PrintStream, which rather than actually printing anywhere, creates this Array that you want. Then call System.setOut(PrintStream s) and give it your special PrintStream. Provide some methods to get at the Array data and you're off!

How to get formatted text into arrays
Dear experts and helpers,
For my project I import an RTF file and then read the data from it into 3 arrays. This works fine when just using the string contents of the paragraphs. However, the final script should be able to read and replace formatted text...
Why use the intermediate arrays? Because otherwise I need to switch back and forth between two fm-documents (and one may be a book component).
The imported file starts with a number of lines separated into two items by a TAB (» denotes a TAB, in FM \x08)
[[Garneau, 1990 #12]] » [9]
The right item may also be locally formatted text, e.g. [9]
Then follow the same (or smaller) number of paragraphs with formatted text like this:
[9] » D. Garneau, Ed., National Language Support Reference Manual (National language Information Design Guide. Toronto, CDN: IBM National Language Technical Centre, 1990.
Is it possible to replace in the body of the function below the following piece
while(pgf.ObjectValid()) {
pgfText = GetText (pgf, newDoc);
gaBibliography.push(pgfText);
pgf = pgf.NextPgfInFlow;
with this
while(pgf.ObjectValid()) {
gaBibliography.push(pgf);
pgf = pgf.NextPgfInFlow;
Do I need a special declaration of the array gaBibliography ?
And how to get the right part of the intro lines as formatted thingy into array gaFmtCitsFmt ?
Currently I read into arrays only the 'strings' (function GetText not shown):
var gaFmtCitsRaw = []; // left column in processed RTF
var gaFmtCitsFmt = []; // right column in processed RTF
var gaBibliography= []; // bibliography lines from processed RTF
// filename is something like E:\_DDDprojects\FM+EN-escript\FM-testfiles\BibFM-collected-IEEE.rtf
function ReadFileRTF (fileName) {
var nCits=0, nBib = 0, openParams, openReturnParams, newDoc, pgf, pgfText ;
var TAB = String.fromCharCode(8); // FM has wrong ASCI for TAB
var parts = [];
openParams = GetOpenDefaultParams();
openReturnParams = new PropVals();
newDoc = Open (fileName, openParams, openReturnParams);
pgf = newDoc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf; // get first pgf in flow
// --- read the temp/formatted citations
while(pgf.ObjectValid()) {
pgfText = GetText (pgf, newDoc);
if (pgfText.substring (0,2) == "[[") { // citation lines start with [[
parts = pgfText.split(TAB); // get the two parts of the line
gaFmtCitsRaw.push (parts[0]); // Push the result onto the global array
gaFmtCitsFmt.push (parts[1]);
pgf = pgf.NextPgfInFlow;
} else { break }
// --- read the bibliography
while(pgf.ObjectValid()) { // until end of doc
pgfText = GetText (pgf, newDoc);
gaBibliography.push(pgfText);
pgf = pgf.NextPgfInFlow;
newDoc.Close (Constants.FF_CLOSE_MODIFIED);
} // --- end ReadFileRTF
The next questions then will be how to modify Ian Proudfoot's FindAndReplace script to handle formatted text as replacement. IMHO i will need to use copy/paste ...Klaus,
Working with text is about the most complicated thing to do within FrameMaker. It seems counter-intuitive, since it is about the easiest thing to do with the GUI. But alas, once you remove the ability to select with a mouse and type with a keyboard, text becomes a wild jungle of complexity.
Text ranges are not too bad, once you get the general idea. It is just that... a range of text, like something you would select with a mouse. Like a mouse selection, it starts before some character in some paragraph and ends after some character in some paragraph. It may be the same paragraph, which is a selection within a paragraph. The character can even be the same, which is then just an insertion point (cursor) somewhere.
So, a text range is a data structure that defines two paragraphs and two characters. In the jargon of scripting, the character is called an "offset." An offset is simply the number of characters past the beginning of said paragraph, where 0 is the beginning.
For example, if you want to capture the first five characters of a paragraph as a text range, you can do this, where 'pgf' is some paragraph object:
var textRange = new TextRange();
textRange.beg.obj = pgf;
textRange.beg.offset = 0;
textRange.end.obj = pgf;
textRange.end.offset = 5;
If you want to capture a whole paragraph, change that last line to the number of characters in the pgf, or you can do this:
textRange.end.offset = Constants.FV_OBJ_END_OFFSET;
...where that constant is just some built-in thing that means "get me to the end of whatever." It's a convenience of the interface.
I'll also note that a text range is actually just an array of two text location structures, one named 'beg' and one named 'end.' If you think of a text location as defined by paragraph and an offset from the first character, maybe that will make more sense.
Text item structures are a whole new mess of complexity. I can't possibly go into an explanation of them here.
I think that many ES developers (definitely myself included) still use the FDK documentation because it is considerably more comprehensive. The two interfaces are largely parallel, but of course somewhat different in the language syntax. Consider that as a potential resource.

Now...I need that the first JSP work very well, because...with that way...I can do queries and obtain the needed results for showing them in the Browser......
So, I already find out�.that�any string that I send to the browser with System.out.println(); isn�t showed�.so it is the reason of my question�..how I can see my results of a query using a loop (like a for, while) resolving it....I think my problem would be resolved.
So...I hope you understand me, and you could help me please...thanks.....

Add an array of strings into ArrayList
Hi Guys
I would like to add an array of strings into an ArrayList, which i have implemented by using the following code:-
String[] strReturnWords = getInput2(line);
List.add(strReturnWords);strReturnWords returns an array of Strings.
How do i retrieve the array of strings from the ArrayList. I have tried
String[i] strString = List.toString();Am i doing this correctly, are their any other ways??
Many thanks
JasonThat should work.NO. That wont work AT ALL.
This:
String[] arrayOfString = new String[listName.size()];Is not right. The number of elements in the list is MUCH different
then the size of the array which is an element in the list.
This:
arrayOfStrings[ i] = (String)listName.get(i);Will fail. The list contains an Object of StringArray not an Object of String.
import java.util.*;
public class StringList{
public static void main(String[] args){
String text = "this is some text";
String[] words = text.split("\\s+");
ArrayList list = new ArrayList();
list.add(words);
String[] array = (String[])list.get(0);
for(int i = 0; i < array.length; i++){
System.out.println("Word: " + array); -
Logger ConsoleHandler strangeness on System.out
Hi all,
I have been scratching my head all day trying to work out what is going wrong with the following code. It's the minimal test case I could come up with to replicate something we're seeing in our codebase. I'd be greatly obliged if somebody could please offer some insight.
In this code I am using the java.util.logging API to create 2 loggers. In the first Logger I am adding a custom handler which inherits from ConsoleHandler but redirects the messages to System.out instead of System.err. It's very simple, but I suspect there is a subtlety here which is the cause of the problem.
Both Loggers should inherit the parent logger by default... which should also spit out logs to System.err
However, if you run the code you will only see one piece of text output in your console and not 4 as expected. Basically, none of the System.err messages get printed! I've tested this on Java 5 in both Apple Leopard and 64bit Ubuntu.
import java.util.logging.ConsoleHandler;
import java.util.logging.Logger;
public class TestLogger {
static class StdOutConsoleHandler extends ConsoleHandler {
public StdOutConsoleHandler() {
super();
setOutputStream(System.out);
public static void main(String[] args) {
Logger logger1 = Logger.getLogger("test1");
logger1.addHandler(new StdOutConsoleHandler());
logger1.info("You should see this twice... but I bet you only see it once.");
Logger logger2 = Logger.getLogger("test2");
logger2.addHandler(new ConsoleHandler());
logger2.info("You won't even see this one at all!");
// BUG: Where has the stderr logging gone?
}Incidentally, if you rearrange the code so that logger2 is created first... it works a little bit more like you'd expect, but not entirely. How strange!
Logger logger2 = Logger.getLogger("test2");
logger2.addHandler(new ConsoleHandler());
logger2.info("You will now see this twice in System.err, as expected");
Logger logger1 = Logger.getLogger("test1");
logger1.addHandler(new StdOutConsoleHandler());
logger1.info("You should see this twice... but I bet you only see it once.");Thanks for the Java 6 report. I thought perhaps it was fixed in Java 6 because I only seen this when I backported. Perhaps I just didn't notice it before now.
My preferred solution is still to copy the entire ConsoleHandler code into a new class and change the reference from System.err to System.out. The point of my class is to have logging on stdout through this handler, I don't want to see anything on stderr*
*actually I do want to see output on stderr, but only if the Level is high enough. By using a stdout handler, it can be set to capture at Level.CONFIG and then I have a ConsoleHandler (i.e. stderr) listening to Level.WARNING and above. But that's besides the point. I also have FileHandlers and all sorts for use in tomcat. It's best to have each Handler only output to one location. -
Redirecting System.out to a JTextArea
How can I redirect the System.out Stream into a JTextArea?
I found the method System.setOut(PrintStream out) but I don't know
how to get the PrintStream of my TextArea.I don't know if this is the most efficient way but it provides an example of using Pipes:
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TextAreaStream extends JTextArea implements Runnable{
private static final PipedOutputStream _pipeOut = new PipedOutputStream();
static{
System.setOut( new PrintStream(_pipeOut) );
private InputStream _pipeIn;
private byte[] buffer = new byte[256];
public TextAreaStream(){
this(1,10);
public TextAreaStream(int numRows, int numCols){
super(numRows, numCols);
Thread t = new Thread(this);
t.setDaemon(true);
t.start();
try{
pipeIn = new BufferedInputStream(new PipedInputStream(pipeOut));
catch(IOException e){
System.err.println("Error creating pipe: "+e);
public void run(){
while(true){
try{
//blocks at read
int bytesRead = _pipeIn.read(buffer);
append(new String(buffer,0,bytesRead));
catch(IOException e){
System.err.println(e);
public static void main(String[] args){
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JTextArea text = new TextAreaStream();
text.setBorder(BorderFactory.createTitledBorder("System.out"));
f.getContentPane().add(text);
//Add an input component
JPanel north = new JPanel(new FlowLayout(FlowLayout.LEFT));
final JTextField field = new JTextField(25);
north.add(field);
north.add(new JLabel("Add text, press Enter"));
f.getContentPane().add(north, BorderLayout.NORTH);
field.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
System.out.println(field.getText());
field.setText("");
f.setSize(600, 400);

I've got class Interpreter from BeanShell. This class runs dynamically cnostructed java code.
The problem:
Interpreter.eval("some commands");prints results into System.out,
while I want it to print results to "out" implicit variable of a JSP implementation.
How can I solve this problem?If only I could make System.out to print into array of strings - it would solve my problem...

How to shrink an array of strings
I am working on the method shift() which is similar to the one found in Perl. This method will take an array of strings and return the first string in the array. The resulting array should shrink by one element.
However, I am having trouble with getting the array modified.
I will show the output and the code.
java DemoShift a b c
Args len: 3 Argument #0: a
bcc
Args len: 3 Argument #1: b
ccc
Args len: 3 Argument #2: c
ccc
As you can see, I expect the array to get smaller each time, but I was unsuccessful. I have tried the following approaches:
1. Convert the array of strings into StringBuffer by using append() and adding some delimeter, and then then using toString().split()
2. Use ArrayList class to change the array length
3. System.arraycopy.
Here is the code. Let me know what do I need to get the array "args" get shrinked every time.
<pre>
import java.util.*;
import java.io.*;
class DemoShift
public static void main(String args[])
for (int counter = 0; counter < args.length ; counter++)
System.out.println("Args len: " + args.length + " Argument #" + counter + ": " + shift(args));
for (String st:args) System.out.print (st);
System.out.println();
public static String shift(String... args)
StringBuilder sb = new StringBuilder(args.length-1);
String firstString = args[0];
String temp[] = new String[args.length -1];
for (int counter = 1; counter < args.length; counter++)
sb.append(args[counter]);
sb.append("MYSPLIT");
temp = sb.toString().split("MYSPLIT");
System.arraycopy(temp, 0, args, 0, temp.length);
return firstString;

Hi everybody,
Could anybody help me this( I finished step 1 and step 2, but not step 3 )
Step1: I type a whole string when i were asked by computer:
"I am a new student of Java programming"
Step 2: I want to break this sentence into words as: "I", "am", "a", "new", "student"...
Step 3: And then, I want to store these words into an array of string. But I do not know how?
Here is my codes:
// Step1
String wholeString = keyboard.readLine();
// Step2:
StringTokenizer myString = new StringTokenizer(wholeString, " ");
String[] mySubStrings = new String[myString.countTokens()];
for(int i =0; myString.hasMoreTokens(); i++)
mySubStrings[i] = new String(myString.nextToken());
for(int j = 0; j< mySubStrings.length; j++)
System.out.println(" " + mySubStrings[j]);
// Step 3 (Could any body help me. I tried it many times, but i got errors !)
Thank you very much in advance. I appreciate.
still_learnThank you very much, danperkins. Actually i missed typing.
But could you or anybody help me do step 3 ? OK I made it more briefly and simply like this:
I have 5 strings: "I", "am", "a","new", "student".
How can i store them into array of string as "
String[] myStorage = {"I", "am", "a", "new", "student"};
How could i do that?
Thank you very much.

lecteurFichier.close(); // toujours fermer le fichierHi,
Thanks for your reply,
1) Yeah I have a method that asks the question and assigns it to a variable.
2) Well the z will stop once there is no lines to read no?
for the set.add(), I am not that familar...
I changed bit a code and I have this now:
if (z > 4) {
for (int i = 0; i < intervalleDiagramme.length; i++)
System.out.println(intervalleDiagramme);
if(intervalleDiagramme[i].equals(valeur))
System.out.println(intervalleDiagramme[i] + " " + valeur);
unique = false;
if (unique)
intervalleDiagramme[j] = valeur;
EDIT:
I figured a way to assign " " to all the values in my array. But I get this error:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 380
at TP3.lireFichier(TP3.java:305)
And my line 305 is: intervalleDiagramme[j] = valeur;
EDIT2:
So ok I found my mistake and corrected it. But I want to know is there a way of doing this without setting the size of the array? because sometimes there needs to be 21 values sometimes 19 and sometimes 20....
If I take out: = new String [21] out I get a NullPointer error...
