Easy one - Put "" into a String ?
How can I put the character " into a string ?
Java thinks I am ending the string when it sees "
I'm sure there is a special character to use but I'm not sure.
Thanks
Josh
If you put a backslash character '\' in front of your " it will put it in the String.

I have a long string which includes "
how do I put this into a string as
String s = " he said "hello"..." ;
obviously doesnt workThat's easy just use escape sequences,
such as if you want to put " you should prepend it by \ such as \" .
similarly if you want to put \ you should have \\. -

i downloaded an album on itunes using my new itouch; but it's only allowing me to put three songs at any one time into the music app...how can i get it to just move them all in there?
hi philly, thanks for getting back to me, especially on such a busy day.
I don't think that's quite the issue though. I bought an album and it appears in 'my purchases' within the itunes app. Yet, in order to listen to the music, i must use the 'music' app and in this application, there are only three tracks displayed at any one time from my downloaded album.
I can 'download all' from the 'my purchases' section but that still doesn't help, it just keeps the last three tracks downloaded in the music app.
I have the 'icloud' enabled and wondered if it had anything to do with that.
i have successfully downloaded another full album totally into the music app, but this first album is causing me problems. -
When I put a burned cd from one Mac into another Mac, song titles do not show up! I have to enter them manually! My CD player reads the titles that i on the cd; how can I get my Mac to do so?
The problem is that I burned these CD's myself from music that I added from my personal collection to iTunes. The INFO is ON the CD's (it appears perfectly when I put the CD in my Numark mixer...so I know the info is on the CD), but for some reason, my MAC PRO will NOT read the info on the burned CD when I place the CD into the MAC PRO. The CD was burned on a MAC that I no longer own. But there HAS to be a way to transfer songs from a burned CD with the INFO that is on the CD burned with iTunes.
PLEASE HELP!

SQL*Loader - How to combine Flat File 3 columns and put into one single column
Receive a flat file delimited by comma. Want to combine Flat File last 3 columns and put into one single column(Table).
e.g.
Flat File
100,239,30,20,30
While inserting into table want to combine last 3 columns and insert into invoice number column.
302030It is not possible to combine the last 3 columns as those columns are seperated by commas and in the SQL Loader control file you must ve specified COMMA as an delimiter. So u better have all the columns in the table plus add one more column which holds the concatenation of the 3 columns.

Adding multiple same-name nodes from one xml into another
Hi,
Following on from my question the other day (Adding multiple different nodes from one xmltype into another), I now have a slightly more complex requirement that I cannot work out where to start, assuming that it's something that can reuse some/all of yesterday's work (thanks again, odie_63!). ETA: I'm on 11.2.0.3
So, here's the (slightly amended) xml along with yesterday's solution:
with sample_data as (select xmltype('<root>
<xmlnode>
<subnode1>val1</subnode1>
<subnode2>val2</subnode2>
</xmlnode>
<xmlnode>
<subnode1>val3</subnode1>
<subnode2>val4</subnode2>
</xmlnode>
</root>') xml_to_update,
xmltype('<a>
<b>valb</b>
<c>valc</c>
<d>
<d1>vald1</d1>
<d2>vald2</d2>
</d>
<e>vale</e>
<f>valf</f>
<g>
<g1>valg1</g1>
<g2>valg2</g2>
</g>
<h>
<h1>valh1</h1>
<h2>valh2</h2>
</h>
<multinode>
<name>fred</name>
<type>book</type>
<head>1</head>
</multinode>
<multinode>
<name>bob</name>
<type>car</type>
<head>0</head>
</multinode>
</a>') xml_to_extract_from
from dual)
select xmlserialize(document
xmlquery(
'copy $d := $old
modify (
insert node element extrainfo {
$new/a/b
, $new/a/d
, $new/a/f
, $new/a/h
} as first into $d/root
return $d'
passing sd.xml_to_update as "old"
, sd.xml_to_extract_from as "new"
returning content
indent
from sample_data sd;
That gives me:
<root>
<extrainfo>
<b>valb</b>
<d>
<d1>vald1</d1>
<d2>vald2</d2>
</d>
<f>valf</f>
<h>
<h1>valh1</h1>
<h2>valh2</h2>
</h>
</extrainfo>
<xmlnode>
<subnode1>val1</subnode1>
<subnode2>val2</subnode2>
</xmlnode>
<xmlnode>
<subnode1>val3</subnode1>
<subnode2>val4</subnode2>
</xmlnode>
</root>
However, I now need to add in a set of new nodes based on information from the <multinode> nodes, something like:
<root>
<extrainfo>
<b>valb</b>
<d>
<d1>vald1</d1>
<d2>vald2</d2>
</d>
<f>valf</f>
<h>
<h1>valh1</h1>
<h2>valh2</h2>
</h>
<newnode>
<name>fred</name>
<type>book</type>
</newnode>
<newnode>
<name>bob</name>
<type>car</type>
</newnode>
</extrainfo>
<xmlnode>
<subnode1>val1</subnode1>
<subnode2>val2</subnode2>
<type>book</type>
</xmlnode>
<xmlnode>
<subnode1>val3</subnode1>
<subnode2>val4</subnode2>
<type>car</type>
</xmlnode>
</root>
If it's easier, I *think* we would be ok with something like:
<newnode>
<type name="fred">book</type>
<type name="bob">car</type>
</newnode>
The closest I've come is:
with sample_data as (select xmltype('<root>
<xmlnode>
<subnode1>val1</subnode1>
<subnode2>val2</subnode2>
</xmlnode>
<xmlnode>
<subnode1>val3</subnode1>
<subnode2>val4</subnode2>
</xmlnode>
</root>') xml_to_update,
xmltype('<a>
<b>valb</b>
<c>valc</c>
<d>
<d1>vald1</d1>
<d2>vald2</d2>
</d>
<e>vale</e>
<f>valf</f>
<g>
<g1>valg1</g1>
<g2>valg2</g2>
</g>
<h>
<h1>valh1</h1>
<h2>valh2</h2>
</h>
<multinode>
<name>fred</name>
<type>book</type>
<head>1</head>
</multinode>
<multinode>
<name>bob</name>
<type>car</type>
<head>0</head>
</multinode>
</a>') xml_to_extract_from

select xmlserialize(document
xmlquery(
'copy $d := $old
modify (
insert node element extrainfo {
$new/a/b
, $new/a/d
, $new/a/f
, $new/a/h
, element newnode {
$new/a/multinode/name
,$new/a/multinode/type
} as first into $d/root
return $d'
passing sd.xml_to_update as "old"
, sd.xml_to_extract_from as "new"
returning content
indent
) fred
from sample_data sd;
Which produces:
<newnode>
<name>fred</name>
<name>bob</name>
<type>book</type>
<type>car</type>
</newnode>
- obviously not right!
Can anyone provide any hints? I've tried searching for similar examples, but I mustn't be putting in the right search terms or something!odie_63 wrote:

So we're going with the second method, but I've discovered that the "$i/name" node is not always present. When that happens, I would like to use a default value (for example, "george"). I promise I've searched and searched, but I'm completely failing to turn up anything that sounds remotely like what I'm after (seriously, I can't believe my google-fu sucks this badly!).
Is there a simple way of doing it? The only thing that I've found that looks vaguely relevant is "declare default namespace...." but I'm not sure that that's the correct thing to use, or if it is, how I'm supposed to reference it when populating the attribute value. -
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 do I copy the string portion of an enum into the string portion of a cluster?
I want to do this for the an entire array of clusters. I'm trying to use a for loop. Can't figure out how to parse the string portion of the enum into the string portion of the cluster.
Alternatively, I'd be happy if I could figure out some way to tie the enum to the array of clusters, but I figure that gets problematic.

OK, let's say that the enumerated type has N elements. I want to initialize an N element array of strings. How do I reference each string in the enumerated type to get to each string?
Easy way to do this is to use GetNumericInfo.vi, part of the Variant library, found in vi.lib\utility\VariantDataType\GetNumericInfo.vi. Wire your enumeration to the Variant input; one of the outputs is an array of the strings in the enumerated type.
The more complicated way is a for loop, in which you typecast the iterator terminal value to the enumerated type, then use Format Value. You can get the maximum value of the enumeration by casting 0 to the enumerated type, then decrementing; cast that back to a numeric and add one to get the right value to wire to the N terminal.
EDIT: just thought I'd add, since RavensFan's reply popped up while I was writing mine - I don't like the Strings[] approach because it doesn't work on RT targets, and I lost a lot of time once due to this trying to figure out why my code wouldn't run properly on an RT system but worked great on my development computer. -
Embed one project into another (nesting)
One feature that I would love to have in a slide show software is the ability to embed one project into another. Is this a feature of Keynote?
Here is where it would be handy:
I was in a band an we needed to put all of the lyrics for our original songs up on the big screen when we were playing. Neither or "set list" nor order was finalized, but was going to be 10 songs out of a possible 15. We wouldn't know until only minutes before going on. Since I play bass and had to be on stage, I had to have it simple enough for a 12 year old kid to run the presentation.
I could figure no way that I could possibly cut and paste and remove all the slides into the correct order right before going on stage. I worried about this for 2 days and figured out what to do.
I used Adobe Indesign and set each song up as it's own file. Then using InDesign's build book feature, I linked all the files into a book file. 5 minutes before the show, I resorted the chapters in the book file, and exported to PDF. I ran the PDF in full screen mode and the 12 year old girl just sat there and hit the spacebar for our songs. It worked perfectly.
Is there a way that I can do separate projects in Keynote and assemble them quickly like I did with InDesign and Acrobat?
Thanks,
KirkOK, if you don't want them all in the same Keynote file so you can hyperlink around the file to the desired slide numbers, then try this.
Create your Keynote of a song. Name it easily so you can find it easily. At the end of each song keynote, put a "Return to Index" and hyperlink it to the Keynote with the program. On the program slide you can Name the songs, Song 1, Song 2, Song 3, and Song 4. Of course, you can enter the name of the song in the program slide. If you use the generic name the process of creating the hyperlink is an easy one (it's even easy if you enter the name of the song you want). If you keep all song Keynotes in the same folder with the index, it's a matter of selecting the file title as the Keynote slideshow to hyperlink to. So you can change the four songs in a program presentation in about 2 minutes max. so you get:
File name: Agenda
Modern Church of God
Sunday, October 10, 2010
Reverent I M. Religious, presiding
10:30 am
Call to order
Song 1 (hyperlink to "Rock of Ages")
Processional
Prayer
Song 2 (hyperlink to "Bringing in the Sheaves")
Announcements
Reading
Song 2 (hyperlink to "Ave Maria")
Sermon, "How do we maximize our resources."
Song 3 ((hyperlink to "Jesus Loves Me")
Digressional
Song 4 (Oh, What I friend we have in Jesus)
At the end of the Rock of Ages lyrics Place
"Return to Program" and hyperlink to "Agenda"
For the next week, "Agenda 10/17" Change the hyperlinks for songs to the new selection of keynotes you have created earlier. It will take about a minute or two to make the changes. You do each one by clicking the Enable hyperlink selection box when one of the song references is selected. The pull the pull down menu to Keynote Slideshow. A box will open. Go to your folder with all song and agenda files. Select the song keynote you want to access with the click, when you select the song file and click "Open" your connection is made. You then project the agenda file on Sunday morning. When you reach song 1, you click on it and the song's keynote comes up. When the song is finished, click on Return to Program and your program Keynote is back up.
The only time consumer in this process is entering the song lyrics into their own keynote files. If you have somewhere to copy and paste the words, then it's easy. The mechanics of creating the weekly connection is very easy. Once you have your resources created, preparation time for a Sunday program will be only a long as it takes you to enter the planned agenda components.
