Finding the length of a string

hi im pretty new to all this,
I am adding a part to my very basic program where the user can type "y" or "n" after they are being asked if they want to continue, I have been able to do this ok but im trying to make the program as air-tight as possible and i'm having troubble with the error checking.
I have told the program what to do next based on the first character the user has typed (character 0), I would like my prorgam to prevent continuation if more than one character was entered into the string. At present it still recognises ydr (example) as a valid entry, is there anyway i can detect if there is more than one character in the sting? by doing so i'll be able to throw back an error to the user.
do
System.out.println("Would you like to continue (y/n)");
System.out.println("");
tmpans = scan.nextLine();
      if (tmpans.length > 1)
      //i know the above method of detecting the length dosn't work with strings, is there an alternative?
        exchar = true;
        System.out.println("You have entered too many characters");
      else
        exchar = false;
      while (exchar);
      if (tmpans.charAt(0) == 'y')
... etc

String.getLength()Errr... String.length() ?Ya right. Whatever. lol
It's still early in the day for me

Find the length of a string in pixels

Hello all,
Wondering if there's a way in PowerShell to find the length of a given string in pixels?

That would depend on the font used to draw it, including size, bold / italic, etc. Assuming you know those things, there's a TextRenderer.MeasureText method in the Windows Forms library:
$string = 'This is my string. There are many like it, but this one is mine.'
$font = New-Object System.Drawing.Font('Arial', 12, [System.Drawing.FontStyle]'Bold, Italic')
$size = [System.Windows.Forms.TextRenderer]::MeasureText($string, $font)
$size.Width

How do i find the length of a string??

trying to use the substring, I know the beginIndex (in my case 10), but the string will vary in size and so i need to find the last character and set it as the endIndex, how do i do this?
public String substring(int beginIndex,
int endIndex)Returns a new string that is a substring of this string. The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. Thus the length of the substring is endIndex-beginIndex.
Examples:
"hamburger".substring(4, 8) returns "urge"
"smiles".substring(1, 5) returns "mile"
Parameters:
beginIndex - the beginning index, inclusive.
endIndex - the ending index, exclusive.
Returns:
the specified substring.

Hi
To substring the string where u know the begin index and want to extract till the end use the following function from the String class of the java.lang package
String substring(int beginindex);
String test = "Hello";
String xx = test.substring(1);
The Value stored in xx will be ello
This is in case u need till the end of the String
If wanna skip the last character u can
use
String substring(int beginindex,int endindex);
String test = "Hello";
String xx = test.substring(1,test.length()-1);
The Value stored in xx will be ell

Find the length of a String, without using any String API

Hi All,
I need to write an method which will accept String obj as an argument and will return its length, but method should not have any String API.
Please help

Please helpWell I have strongly argued against doing this, (it seems like a pointless exercise), and I have even stated that it cannot be done, even Reflection at some level will use a String method. I have not bothered to dissect wether the same is true with JNI. However, if we take the statement of the original problem exactly as stated, particularly the
but method should not have any String API.i.e. we don't care if a String API is used 'under the covers', just so long as there is no direct usage in the new method that is written, then the answer is trivially easy:
public class Main
    public static void main(String args[])
        Main worker = new Main();
        String str = "123456789";
        int len = worker.strLenUsingNoExplicitStringClassMethod(str);
        System.out.println("Length of string \""+str+"\""+" is "+len);
    public int strLenUsingNoExplicitStringClassMethod(String string)
        StringBuilder sb = new StringBuilder(string);
        return sb.length();
}

Finding the key according to string length in java.util.Properties

Finding the key according to string length in java.util.Properties.
I know only String length only.

i need to retrieve the values from the java.util.properties.
we know that we need to give the key value in order to retrieve the datas.
but my problem is i will give the length of the key instead of giving the key value but i need to retrieve the datas according to the length of the key.

How is the length of a string calculated in Java? and JavaScript?

Hi all,
Do any of you know how the length of a string is being calculated in Java and JavaScript? For example, a regular char is just counted as 1 char, but sometimes other chars such as CR, LF, and CR LF are counted as two. I know there are differences in the way Java and JavaScript calculate the length of a string, but I can't find any sort of "rules" on those anywhere online.
Thanks,

What's Unicode 4 got to do with it? 1 characteris 1
character is 1 character.
strings now contain (and Java chars also) is
UTF-16 code units rather than Unicode characters
or
code points. Unicode characters outside the BMPare
encoded in Java as two or more code units. So it would seem that in some cases, a single
"character" on the screen, will require two charsto
represent it.So... you're saying that String.length() doesn't
account for that? That sux. I don't know. I'm just making infrerences (==WAGs) based on what DrClap said.
I assume it would return the number of chars in the array, rather than the number of symbols (glyphs?) this translates into. But I might have it bass ackwards.

Any method to find out length of a string !!

Hello friends,
              I used <i><b>describe</b></i> statement to find out the length of a string, but it actually returns the whole length of the string but not actual no. of char's in this.
any one suggest a solution for this.
Senthil

Hi Senthil
The ABAP function STRLEN returns the length of a string up to the last character that is not a space.
[COMPUTE] <n> = STRLEN( <c> ).
STRLEN processes any operand <c> as a character data type, regardless of its real type. There is no type conversion.
As with mathematical functions, the keyword COMPUTE is optional.
DATA: INT TYPE I,
WORD1(20) VALUE '12345'.
      WORD2(20).
      WORD3(20) VALUE ' 4 '.
INT = STRLEN( WORD1 ). WRITE INT.
INT = STRLEN( WORD2 ). WRITE / INT.
INT = STRLEN( WORD3 ). WRITE / INT.
The results are 5 , 0, and 4 respectively.

Finding the length of a path

hey,
i'm using cs3 and i have a few simple paths (curves) and i'd like to know the length of these curves but i can't seem to find an option, or whatever, for that.
thanks

You mean the length as you travel along the curves?
Can't be done I'm afraid, at least not very accurately.
If it's really important you could try arranging a whole lot of little squares along the path so that they touch each other and then counting them. But the result won't be accurate unless the squares are very small.
However, if you know how the curves are constructed geometrically you can sometimes calculate their lengths.
For example if the curve is an arc of a circle and you know the angle it subtends as a proportion of 360 degrees then it's fairly easy to use pi to find the length of it.
Circumference of a circle = pi x diameter.

How to find the length of the resultset

how to find the length of the resultset

(Doing a select count as somebody suggested is nota
good solution, as the count can change betweenyour
count query and your real query.)And the number of rows can't change between getting
the last one and doing the actual work?I don't think so. Once you've got the ResultSet, I don't think it will change under you, unless you explicitly set it to SCROLL_SENSITIVE.
I could be mistaken though.

How to calculate the length of a string

Hi everyone,
A simple question. How to calculate the length of a string?
Thanks!

Hi Wuyia Nata,
As everyone has suggested you search the forum before posting a question, i guess for basic questions u never have to post a question, you will get the answer in your search. Anyways see the code below for string lenght.
Data:
w_string type string,
w_lenght type i.
w_string = 'vhdskbvsdkbvdsvnsknvs'.
w_lenght = strlen( w_string ).
Write:
w_lenght.
With luck,
Pritam.

Checking the length of a string in sapscript

Is there a way to check the length of a string in sapscript?
What I want to do is, if the length of two strings is greater than a certain ammount, truncate the string.
But I don't know if is possible inside the sapscript

Never mind, I did it with a perform instead

Chnage colum from CLOB to Varchar2 and find the length of CLOB

Hi,
I have got tables contain CLOB fields. I want to converter them to varchar2? Is the a way to do it? how can I find the max of length the data in CLOB fields.
Thanks in advance!!
Michael

Hi All,
Thanks you for your useful information. What I need is to change the colum data type (definaition itself)from CLOB to Varchar2, not just to display the values in CLOB field into varchar2. I have tried to change the date type from COLB to varchar2 in TOAD and got ORA_22859: invaliad modification of columns.
Any suggestions?
Many Thanks
Michael

How can i get the length of a string with Simplified Chinese?

when i use eventwriter to add content to a xmldocument,there are some chinese simplified string in it,i use String.length() for the length ,but it is not correct~how can i get the right length for eventwriter?

Below is a simple patch for this problem. Using this patch you need to pass 0 as the length argument for any XmlEventWriter interfaces that take a string length.
