How to add newline into a string

I need to define a string which contains a newline,
what i did is :
String newline = new String();
newline = "\n";
but when i add new line to other string, and print it out,
seems it is not working....
Anrybody knows why?
thanks~

Please keep in mind that newlines differ between platforms. The "\n" is very well known, however in the Windows world a newline is actually "\r\n". Thankfully you may retrieve this value from the JVM.
String newline = System.getProperty("line.seperator");Also System.out.println() will automatically append the correct newline at the end.
Meaning that
System.out.println("Hello");
System.out.print("Hello" + newline);are esentially the same.

How to add elements into java string array?

I open a file and want to put the contents in a string array. I tried as below.
String[] names;
s = new Scanner(new BufferedReader(new FileReader("outfile.txt")));
while (s.hasNext()) {
                String item = s.next();
                item.trim();
                email = item;
                names = email;
            }But I know that this is a wrong way of adding elements into my string array names []. How do I do it? Thanks.

Actually you cannot increase the size of a String array. But you can create a temp array with the lengt = lengthofarray+1 and use arraycopy method to copy all elements to new array, then you can assign the value of string at the end of the temp array
I would use this one:
String [] sArray = null;
s = new Scanner(new BufferedReader(new FileReader("outfile.txt")));
while (s.hasNext()) {
    String item = s.next();
    item.trim();
    email = item;
    sArray = addToStringArray(sArray, email);
* Method for increasing the size of a String Array with the given string.
* Given string will be added at the end of the String array.
* @param sArray String array to be increased. If null, an array will be returned with one element: String s
* @param s String to be added to the end of the array. If null, sArray will be returned.(No change)
* @return sArray increased with String s
public String[] addToStringArray (String[] sArray, String s){
     if (sArray == null){
          if (s!= null){
               String[] temp = {s};
               return temp;
          }else{
               return null;
     }else{
          if (s!= null){
               String[] temp = new String[sArray.length+1];
               System.arraycopy(sArray,0,temp,0,sArray.length);
               temp[temp.length-1] = s;
               return temp;
          }else{
               return sArray;

How to add TickMark into dropdownlist?

Hello,
i am looking for dropdownlist with multiple selection.
Is there a DropDownList widget allows more than one menu item to be selected at a time?
i got ans from forum
http://forums.adobe.com/message/3319311#3319311
they said we can add tickmark into dropdownlist.so that we can select more than one item.But How to add Tickmark into dropdownlist? OR can we custmize dropdownlist?
please, give some hint.
If Anybody knows the solution , please help me.

I think there are two ways:
1) Use a specific control with text tokenization, like a Telerik's one RadAutoCompleteBox (user1's text is a token, and user2's text is an editable
text area);
2) Use CSR (client-side rendering; JSLink field of a list EditForm's web part) to make the original field (input tag) read only and dynamically add second text
box for user2's editable text. Then on form submit you can combine the two values: read only one and dynamically edited. You may do so via overriding the PreSaveAction() JavaScript function in your JSLink file.

How to catch exception into a String variable ?

I have a code
catch(Exception e)
            e.printStackTrace();
            logger.error("\n Exception in method Process"+e.getMessage());
        }when i open log i find
Exception in method Process null.
But i get a long error message in the server console !! I think thats coming from e.printStackTrace().
can i get the error message from e.printStackTrace() into a String variable ?
I want the first line of that big stacktrace in a String variable.
How ?

A trick is to issue e.printStackTrace() against a memory-based output object.
void      printStackTrace(PrintStream s)
         // Prints this throwable and its backtrace to the specified print stream.
void      printStackTrace(PrintWriter s)
//          Prints this throwable and its backtrace to the specified print writer.Edited by: BIJ001 on Oct 5, 2007 8:54 AM

something like this will convert string to byte[]
e.g.
you want to convert following.
656667 => ABC
String toConvert = "656667";
byte[] returnVal = String2byteArr (toConvert );
String FinalStr = new String(returnVal);
public static byte[] String2byteArr(String Result)
byte[] byteRet = new byte[Result.length()/2];
int k=0;
for (int j=0; j<(Result.length()); j+=2)
try
Integer I = new Integer (0);
I = I.decode ("0x"+Result.substring(j, j+2));
int i = I.intValue ();
if (i > 127)
i = i - 256;
byteRet[k++] = new Integer(i).byteValue();
catch(Exception e)
System.err.println(e);
return byteRet;
}// String2byteArr
Hope this will help you, So that i can get 3$ (:-)

How to add data into JTable

How can I add data into JTable, for instance ("Mike", "Gooler", 21).

How can I add data into JTable, for instance ("Mike",
"Gooler", 21).You will have very good results if you segregate out the table model as a seperate user class and provide a method to add a row there. In fact, if you use the table to reflect a database table you can add the row inplace using the existing cursor. I believe it's TableExample2 in the jdk\demo\jfc\TableExamples that has a very good example of this.

How to: add images into an Interactive PDF

I was wondering if it was possible to add images into an interactive PDF once it has been sent to someone. The PDFs are forms that need to be filled by a client via their iPads using Adobe Expert, and they may need to occasionally attach images to the document and be able to edit these images (i.e. circle parts of the image to highlight them) then send these PDF's back to myself.
Is there a way this can be done?
Thanks

There is no program on the iPad called Adobe Expert. I think you mean Adobe Reader.
Adobe Reader lets you fill in forms but not to attach images. If you wish to make a request of the Adobe Reader product manager, you can post on the Adobe Reader for iOS forum here:

How to add space before a string a variable.

Hi,
If i have a string variable ' 80 '.I want it as ' 80 ' ie some space appended before it.
I used concatenate ' ' variable into variable..Its not working.How to do it??
Thanks.

check below code
Concatenate ' ' string into string respecting blanks.

... RESPECTING BLANKS
Effect
The addition RESPECTING BLANKS is only allowed during string processing and causes the closing spaces for data objects dobj1 dobj2 ... or rows in the internal table itab to be taken into account. Without the addon, this is only the case with string.
Note
With addition RESPECTING BLANKS, statement CONCATENATE can be used in order to assign any character strings EX>text - taking into account the closing empty character - to target str of type string: CLEAR str. CONCATENATE str text INTO str RESPECTING BLANKS.
Example
After the first CONCATENATE statement, result contains "When_the_music_is_over", after the second statement it contains "When______the_______music_____is________ over______" . The underscores here represent blank characters.
TYPES text TYPE c LENGTH 10.
DATA itab TYPE TABLE OF text.
DATA result TYPE string.
APPEND 'When' TO itab.
APPEND 'the' TO itab.
APPEND 'music' TO itab.
APPEND 'is' TO itab.
APPEND 'over' TO itab.
CONCATENATE LINES OF itab INTO result SEPARATED BY space.
CONCATENATE LINES OF itab INTO result RESPECTING BLANKS.

How to add HTML into a muse file?

I'm following google's advice for improving the SEO of a site I've designed in MUSE. I visited their "STRUCTURED DATA Markup Helper Here: https://www.google.com/webmasters/markup-helper/
and they've given me this: after I highlight pointers in my page for google to mark
what I need to know next, please, is how to locate the correct code within muse, in order to insert these highlighted HTML codes into it, so that google can find my pages easier. I have tried opening the relevent file that I use to store the site on my PC, but there seem to be no matching sections of code. I can only see css files.

Hello,
If you're looking to add the code to the head section of the page (which many tracking/analytics codes require), then you can add the code to the Page -> Page Properties -> Metadata -> HTML for head section. If you're looking to add the code to the body of the page, then use the Object -> Insert HTML option.
Hope this helps.
