Finding the position of an integer in a string

I haven't done much Java programming for the past 3 months, but I'm trying to get back into it now, but I'm having some trouble. I'm trying to break up a string of integers, to store each individual integer in an array.
So, if I had something like 132412344, a for loop would put them all into separate arrays.
I know that there is a charAt() function, but is there something like that for integers?

Do you know whether every single character in the string is an integer?
If it is, then toCharArray will get you the array. Then you could loop through it to parse each character into an int. You can use Character.digit to do that.
I doubt that there's any method that automatically splits a string and returns the integers represented by the characters in a string. It seems like too specialized a method. But I could be wrong.

Need help in finding the position of a SubString in a String

Hi All,
I have a VARCHAR2 column in my table which has data similar to '152-425-3265-8-5623-45'.
I want to find the position of the numbers in the column.
For example:
If i give 8 - query should return me 4.
If i give 425 - query should return me 2.
The numbers are delimited with '-' value.
Please help.
Thanks in advance.

Finding the position of the end of a line in a JTextPane

I'm trying to make a JTextPane which expands horizontally if the text being typed in it reaches the right hand edge. To do this I need to know the position in the Document of the end of the current line.
I've managed to write a method which expands the JTextPane vertically using getEndPosition() in AbstractDocument.
There is an endLineAction in the DefaultEditorKit which moves the Caret to the end of the line but I don't want to move the Caret, just find the position of the end of the line. I did have a method before which moved the Caret to the end of the line, stored the position and moved it back but that wasn't suitable.
I suspected the answer was to do with the View but I can't figure out how the View relates to the JTextPane or Document.
Can anyone help?

Well, personally I don't think its a good idea to keep changing the size of the text pane as text is being typed and I doubt the solution will be as easy as you think.
As you type the text will automatically wrap so it will be a little late trying to change the width after the text has wrapped, which means you would need to increase the width "before" text is typed. But then you have another problem because you don't know how much to increase the width by since a single character could be typed or a string of text could be pasted into the text area (people always forget about pasting when doing stuff like this).
Also if text is removed you would need to iterate through all the line to find the longest line and reset the width.
Anyway the only way to know the width would be to play with the modelToView() method. If you want to find the end of the current line then you can use the Element.
Check out my [Text Utilities|http://www.camick.com/java/blog.html?name=text-utilities] class which might give you some ideas on how to use the Element class and modelToView() method.
which has example of using the above Class and method that might give you some ideas.

How can I find the position of a robotic arm with a cFP-CTR card?

Hello,
I use a CTR-500 to measure the pulses of 3 encoders.
The encoders are related to the 3 axis (x,y,z), to which a robotic arm is moving.
Each encoder has 2 channels (A,B) which go to each pair of Count Inputs of the CTR card.
When the robotic arm is moving on one axis, the corresponding pair of Count Inputs is increasing, but there is a phase between the one Count Input and the second one. What is more, the Count Inputs do not decrease when the robotic arm is moving to the other direction, but they still increase.
So, I cannot find easily the position of the robotic arm.
What I have done, is to try finding the position, by using only one Counter Input for each axis. This means that I use the value of the encoder as a counter, and I calculate the position with some software tricks. But for some reason, it does not work properly.
I have heard that the method I use is not proper. Instead, I have been told that I must use the phase of the 2 Count Inputs, in order to find the direction to which the robotic arm is moving. But, the Count Inputs of the CTR are augmenting in parallel, when the robotic arm is moving forward or backward.
How can I find the position of the robotic arm, as it is moving like a CNC ?
Thank you very much.

You don't want to use a cFP-CTR-500 card. What you have are quadrature signals. You should be using the cFP-QUAD-510. It has 4 channels that can handle both the A and B signals of a quadrature encoder. It has the built in circuitry do determine the phasing of A vs. B to know when to count up vs. count down.

Cannot find the ''Positioning Methods'' option on ...

Hello....I have recently bought the C7-00 and I wanted to test my GPS but I could not find the "Positioning Methods'' option to select the A-GPS, so can anyone help on this.
Thank you.

Do you not have a Location app in your Applications Folder ? As CJ mentioned , that is where you set your location methods to on/off. Inside Location you should have 3 sub folders, Landmarks,GPS data and Positioning. Open Positioning and you should be able to change the settings !
If I have helped at all, a click on the White Star is always appreciated :

My 3 apple products, an imac, a macbook air and a macbook lost their contact with their external hard disks. They were LaCie make. And every time I turn my laptops, I find the positions of the keys on their keyboards changed. Why is Apple silent?

After the latest apple IOS upgrade my 3 apple products, an imac, a macbook air and a macbook, lost their contact with their external hard disks. They were LaCie make. And every time I turn my laptops, I find the positions of the keys on their keyboards changed. Why is Apple silent? There are so many people complaining about this issue and expecting Apple to correct this issue that they have created.

Probably because it's not an Apple issue. I have Lacie EHD's connected to my MBAir and iMac, all work perfectly on Mavericks. In addition I don't have any keyboard issues on any of my Apple products. BTW IOS is only for IOS devices such as iPads, iPods and iPhones, Macs use OS X. The two OS's are seperate products designed to run on seperate products.

Find first occurence of an integer in a string

Hi all,
I have a number of strings which go something like "MBNA Flow 12a" and I want to separate the integer from the rest of the string so I can parse it, sort the strings into some sort of order according to their integer, and then put it all back together again. The problem I'm having is finding the position of the integer within the string, so that I can take a substring and/or split the string. I've looked it up and I gather that using regex I should be able to find the beginning and end of the integer, using something along the lines of
Pattern pattern = Pattern.compile("\\d+");
           Matcher matcher = pattern.matcher(temp.getString(1));which I found on another site where someone had the same problem. I've looked at the regex tutorials and according to them this is what I want, but whenever I try it no match is found, and I don't know why. Some sites have claimed that the regular expression has to apply to the entire string, so I would need to also take into account the MBNA Flow etc, something I'm loathe to do as the string is quite unpredictable, but others say that it should work exactly as is.
Any help would be greatly appreciated. :)
Thanks.

Is it possible to get the position of a charcter from a string ?

Hi !
Is it possible to get the position of a charcter from a string ?
Example:
@VAR contains the following text "ABCDEFGHIJKLM"
I'am seaching for FGH, it start on pos. 6 en ends on pos 8.
How can I get these numbers 6 and 8 ?
So, I can use them in the MID(text,start,len) function.
Thanks!

Hi Sooraj,
I'll explain more in detail:
From a web-service I get a variable called @Spec.
This variable contains the following:
"MOTORTYPE[CR]D-QW1234[LF]PART[CR]1234-FRD-X[LF]"
or
"MOTORTYPE[CR]ABC[LF]PART[CR]E-435[LF]"
I need the values behind MOTORTYPE[CR] and behind PART[CR]
But youll see that the positions of these values are different each time.
If there is a way to get the (start) position of "MOTORTYPE[CR]" or "PART[CR]" and the (end) position of the first "[LF]" behind that,
then I could use the MID() function to get the correct values.
The values will be displayed in a table view (between other fields).
An ABAP-call/function wont work . . . how should I invoke this within a table column/field object ? (system action ?)

How do I find the position of a single character on a page?

Hi guys,
I am developing a PDFEditor, but am having trouble implementing the code which finds the location of glyph characters on a page (in device space). I have read the pdf reference on Text, but do not quite understand it.
I have worked out the individual character spacings, but I cannot accurately find the location of the first character .
Here is my current attempt:
float y = CGPDFPageGetBoxRect([current_page pageReference], kCGPDFCropBox).size.height-current_matrix_position.y;
float x = current_matrix_position.x;
float xa = a * x + c * y + e;
float ya = b * x + d * y + f;
text_position = [NSValue valueWithCGRect: CGRectMake(xa, ya, 15, d)];
(where text_position is the location of the start character in device space. a,b,c etc come from the Tm operator.
current_matrix_position is set as a point (e,f) from the cm operator.)
This code seems to work with some PDF files:
But does not work with others:
(Note there is text in the box above the blue which cannot be disclosed for reasons...)
Is there something I am missing (like another operator?) or is my formula completely wrong.
Your help would be greatly appreciated

Hi Irosenth,
I have been reading the spec and trying to understand it for several weeks. Unfortunately, I am still confused with how to find the coordinates of the text.
>> You need to parse the content stream(s) that are associated with the page and
I have done this. My program finds both the cm operator, the tm operator and the font widths etc. Unfortunately, now that I have all of this information, I am unsure what to do with it.
How do I properly add these two matricies together? I have looked in the spec which describes it as:
x' = a * x + c * y + e
y' = b * x + d * y + f
I tried this and the results worked on some pages, but not on others (several thousand x coordinates out...). I am finding the ISO 32000-1:2008 very confusing in this section.
>> manage what you find there
This is the part I am having major trouble with. Using the coordinate transformation matricies, how can I determine the starting coordinate for the first glyph in a text (BT, ET) on a non-scaled page (so 1 unit = 1 pixel) using the matricies?
Thanks

Need to find the memory address of a buffer or string

Two basic questions:
-How does LabVIEW treat the concept of a "buffer"? Isn't it just a string wired from one block to another?
-How can I find the address of a memory location or buffer location?
I am using the Call Shared Library Node to call two functions to unwrap a custom communication protocol packet. I will be reading packets of information from the serial port and sending them through this unwrapper The first function expects as the arguments a)the address of the buffer and b)the length (in bytes) of the buffer. I can measure the length, but am unsure of the address. I would have just wired the string output of the serial port to the input of the unwrapper, but the unwrapper wants the address of that string/buffer. The data type of the buffer address that the function expects is "unsigned char*" in C++ which translates to "uInt8" in LabVIEW according to http://zone.ni.com/devzone/cda/tut/p/id/3009. The second function that is being called writes the unwrapped data to the destination buffer address that I specify as an argument.
I located this VI that handles buffering, but am unsure how it would help me, because it doesn't deal with the address issue either (and it used arrays of doubles, not characters or strings which is what the output of the serial port will be). http://zone.ni.com/devzone/cda/epd/p/id/2499
Any help would be appreciated.

Finding the smallest letter in a single alphanumeric string

How do I find the smallest letter in a single alphanumeric input?
I already wrote and successfully tested the code that takes an alphanumeric string as input, separates the number from the alphabet, and creates a new alphabetic string. However, I'm unsuccesful in writting the code to find the smallest letter within the alphabetic string. I am almost certain that the easy answer is Arrays.sort, but I unsuccesfully tried writing the code to place the alphabetic string into an array. I researched compareTo, but I do not have another object to compare?! Any suggetsions?

Ahh flaimbait - I'm sure I'll get criticized for this... but - while we are talking about time-to-market, etc...:
The most important issue in development is to make sure that you understand the project requirements. The requirements in this situation were:
Find the smallest character in a string.
Given that, then any developer that goes through the trouble of looking up the sort APIs, etc... is not helping themselves - all they really needed to do was to write one line of code (as xxxx graciously posted):
for (int x=0; x<foo.length(); x++) if (foo.charAt(i)<low) low=foo.charAt(x);I absolutely guarantee that any Java programmer could write the above faster than they could figure out how to split a string appart by characters, look up the arraysort API, etc...
The arraysort functions are EXTREMELY efficient, and I would never suggest that someone re-implement them. The point here is that just because you've got a wrecking ball available, you can still use a hammer to drive a nail.
