Char to uppercase?

Hi, I am trying to convert all letters entered by the user to uppercase while leaving all the symbols and numbers alone...
char a,b;
b=a.toUpperCase();
apparently, this toUpperCase() method doesn't work...
Help please~~~
Thanks,

There's no use in badly re-implementing something in a limited way, when a perfectly functioning alternative is available easily.
Don't try to re-implement Character.toUpperCase() (or worse: String.toUpperCase()). You will get it wrong, unless you have a very narrow definition of "character".Hey, what put a bug up your bonnet? If you look at the original post I did you'll see that the Character.toUpperCase was listed as the preferred method to use over the old way.
You can also do: c = c - 'a' + 'A';
Not as good as c = Charater.toUpperCase(c); I do believe that people are able to look, and read and decide for themselves, english speaking or not...
c = Character.toUpperCase(c); means the same in English Java as it does in Japan or in Mexico. In some situations the built in API functions for conversions are not allowed by instructors--and rightly so--they are looking to teach the students what the pit fall and benefits of one method over another is--so when I put out something like that mentioned post, I leave it to the user to decide what is appropriate to use in their situation.

How can i transform lowercase char in uppercase char automatically

I would like that when you write lowercase char in a control string these char be converted automaticaly in uppercase char in this string

wire the control to the "To Upper Case" function and that output to a
local variable of your control.

Manipulating chars

Hi everyone,
I'm still new to Java (and programming!). Can anyone advise me on how to manipulate chars, particularly how to convert a given lowercase char to uppercase? The only way I can do it right now is to convert to String and use toUpperCase() method, but this seems clumsy.
Thanks!

Just to clarify, pervel is reffering to the java.lang.Character.toUpperCase() method. The Character class is a wrapper class - one exists for every primitive type (Integer, Float etc...) and they are mainly of use when you have a library API which demands to return or accept as an argument something of type java.lang.Object - you can't pass an char since this is not an object.
In this example you would take your char variable...
char c = 'c';
...place it in a wrapper...
Character myChar = new Character(c);
...then set the original variable to the return value of the method...
c = myChar.toUpperCase();
...the variable c will now == 'C'.
Wrappers are good in this sense but if you are, for example, converting a large text file to upper-case, you will be creating a huge number of objects making your code slow and bloating out the memory - for speed use the arithmetic algorithm in the first posting / to show you know your way around the API, use the wrapper class...

Use query string between two custom New Form

Hi guys,
i have a New Form . In this form i have a button that open(onClick) another list form (it is a different list). I have to pass a field value from the first form to the other . How can i do this using query string?Help please!
Thank you!

To pass some value with query string, you just need to open the form url with the querystring parameters (jquery needed):
var url = '<yourlist>/newform.aspx?parameter1=' + $('input[Title="Title"]').val()
SP.UI.ModalDialog.ShowPopupDialog(url)
on the second newform.aspx, you can grab the querystring parameters with the Sharepoint native function "_spGetQueryParam('<lower case query key>')"
var x = _spGetQueryParam("parameter1")
Note: make sure you use the key as lowercase, even you if pass it with chars in uppercase.

Convert letters into numbers

I need to write a method that converts letters from a word into a number according to the telephone buttons.
I figured I was at a good start by putting the string of the word into a character array, but how would I assign each of those letters to its corresponding number?
Thanks in advance.

T440s - keyboard is broken after BIOS update to 2.25

Hi,
today I've updated my Lenovo T440s BIOS to 2.25 version. The update was performed using Software updates in Lenovo Solution Center and everything was successful.
After computer reboot the keyboard has been mulfunctioned:
when I hold Windows Key the following char is produced {}Y (moreover on Windows 8.1 speekers turn downs, metro apps panel from W8.1 is show and next chars are uppercase)
when I press/hold Right arrow key the following char is produced ń
This is not OS dependent issue - I tried to use Rigth arrow in BIOS menu and it doesn't work.
Do you have any suggestions what to do? Or any tips how to restore previous version of BIOS?
I'm looking forward to hearing any tips.
qinto

Roll-back to 2.24 version fixed the problem, but the issue with current BIOS version remains.
EDIT: Unfortunately the roll-back hasn't solved the problem - working with keys mentioned above is better, but still holding Win Key and Right Arrow causes the same problems.
Greets,
qinto

This line looks fishy:
if (next == ' ' && next == prevChar)
prevChar = next;Try:
if (next == ' ' && next == prevChar)
next = "";That should take care of the extra blanks, though I didn't test it myself, and could very well be wrong.
Not sure about the uppercase, though I imagine it must be reading the ToUpperCase every time after the first period.

Tokens with digits and alpha. chars not converted to uppercase

Hi
We are using Oracle9i Enterprise Edition Release 9.2.0.2.0.
We have made a CONTEXT Index with the BASIC_LEXER. (Only thing we have changed is BASE_LETTER=YES)
The defaults says, that tokens are converted to all uppercase. But if a token contains digits and alphanumeric chars it remains mixed case.
For example:
Oracle9i is stored in the token table Oracle9i and not ORACLE9I.
Therefore a search with CONTAINS for this token is case sensitive.
Is this a bug or are we doing something wrong?
Best regards,
Beat

This is a bug in 9.2.0.2, and is fixed in 9.2.0.3. Bug # is 2684307.

Converting a char input to uppercase

hello,
what code would i use to convert the input of a char from the user to uppercase
thanks in advance

char someChar;
someChar = whatever_method_you_use_to_get_the_input_char();
someChar = Character.toUpperCase(someChar);or
char someChar = Character.toUpperCase(whatever_method_you_use_to_get_the_input_char());Probably you should post questions like this on the New To Java forum.

Apple bluetooth keyboard don't wrote uppercase chars

Hi everyone! I trying to clean my keyboard and after i finished. some chars like "q" "w" "e" "r" and other don't wrote with shift in uppercase. But if i use caps lock, all ok. i can't all time switch between caps lock. How i can fix it?
Thanks!

Hello:
I suspect the keyboard is faulty.
However, before you replace it, try resetting the PRAM and SMC (instructions are in knowledge base articles).

How to check whether a char string is in uppercase or not

Hi,
I know how to convert strings to change strings to uppercase or lowercase, but is there any function to check, beforehand, if the field is in uppercase, for instance ? The intention here is simply to spare processing in situations where the string is already in uppercase, and thus not needing any further processing (given I want to turn the string into uppercase.)
Thanks in advance,
Avraham

Hi Avraham ,
To check whether the string is in upper case or not use CA keyward.
To check try the following code ---
DATA : W_STRING(5) TYPE C,
W_ABCDE(26) TYPE C VALUE 'abcdefghijklmnopqrstuvwxyz'.
w_string = 'abcd'.
IF W_STRING CA W_ABCDE.
TRANSLATE w_string TO UPPER CASE.
ELSE.
MESSAGE 'It is a uppercase string' TYPE 'S'.
ENDIF.
Try this link this will definitely help you -

CS3/4 Is there a char for an XML tag?

I have a script that gets the value of an XML element. If some of my users make the tagged text wrong, then I get an extra invisible character in the string, and that string is used to make a file name, and then I have problems later since this invisible character is illegal in the filesystem. I'm working on Mac, if it might matter.
So, is there a character that is the equivalent of one of the tagging brackets? Here's how my users are mistakenly making their tags.
Make a new document
draw a text frame, type a couple characters like "foobar"
open tag pallet. Make a new tag like "tag1"
select all text with the text tool.
apply tag to text. You should NOT see tag brackets on the text by default because the entire text frame is tagged.
now select all the text EXCEPT the last character. If you typed "foobar" only select "fooba"
Apply tag. Now you will see tag brackets.
Now unselect text.
Use arrow keys to key forward through text. When you get to the closing bracket, you will have to key over 2x to get the cursor to move. This suggests to me there is an invisible character.
Now when I am running my script, it sometimes picks up the invisible character. I need to be able to strip it off.
Because the length of text varies, I can't chop off "char -1" because sometimes the text is tagged correctly and I don't have the invisible char. I think it's Unicode (maybe?).
If you post some code, please use Applescript. Thx.
Thanks,
Chris

.. and you can remove them with
newstr = oldstr.replace(/\uFEFF/g, "");
(note the UPPERCASE unicode -- for some reason it doesn't work with lowercase \ufeff, while it does in regular strings!)

Changing to uppercase?

I'm trying to change the first letter in a name to uppercase, I dont appear to have a problem chaning the letter to uppercase but I cant change the string. any help would be much appreciated.
thanx.
String name = "james";
          //Get the first character:
          char first = name.charAt(0);
          //Make the char uppercase:
          first = Character.toUpperCase(first);
          //replace the first character:
          StringBuffer nameBuffer = new StringBuffer(name);
          nameBuffer.replace(0, 1, new String(first));
          name = nameBuffer.toString();
          System.out.println(name);

String name = "james";
char[] chars = name.toCharArray();
chars[0] = Character.toUpperCase(chars[0]);
name = new String(chars);

How to read char from console

Hi can any body help me..
I want to read char from keybord. withought pressing ENTER.
I am not sure how i can do it. I can't use
BufferedReader br = new BufferedReader(new InputStreamReader ( System.in )) ;
char key ;
key = (char )br.read() ;
cuz i have to press ENTER every time to read char.
Thanks in advance.

try this,I' have found a part on Internet
package exercises;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Echo {
public static void main(String args[]) throws Exception{
// This is where the magic happens. We have a plain old InputStream
// and we want to read lines of text from the console.
// To read lines of text we need a BufferedReader but the BufferedReader
// only takes Readers as parameters.
// InputStreamReader adapts the API of Streams to the API of Readers;
// receives a Stream and creates a Reader, perfect for our purposes.
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String input = "";
while(true){
System.out.print("ECHO< ");
//As easy as that. Just readline, and receive a string with
//the LF/CR stripped away.
input = in.readLine();
//Is a faster alternative to: if (input == null || input.equals(""))
//The implementation of equals method inside String checks for
// nulls before making any reference to the object.
// Also the operator instance of returns false if the left-hand operand is null
if ("".equals(input)){
break;
}else
// Here you place your command pattern code.
if ("ok".equals(input)){
System.out.println("OK command received: do something �");
//Output in uppercase
System.out.println("ECHO> " + input.toUpperCase());
System.out.println("ECHO> bye bye");
//We exit without closing the Reader, since is standard input,
// you shouldn't try to do it.
// For all other streams remember to close before exit.

Convert char .toUpperCase

Hello again, sorry I have another really nooby question I know it, I don't understand these things with the examples and methods they have posted though.
Basically the user inputs a string (their name), and I take the first character out of that string and place it in a char variable.
I then want to check if it is lowercase, if not then it passes, otherwise it needs converting to uppercase and putting back into the string (not sure if converting the char automatically changes it in the string too).
e.g "enter your name" andrew
--change small a to big A
"display name" Andrew
Yes, I feel extremely stupid, but i've tried to figure it out and I can't, if anybody would mind helping such a newbie i'd appreciate it thanks.
