Testing the last character of a string using .endsWith

Hi,
I want to check to see if the last character of a string is '@'.
I tried if (StringAt.endsWith("a")) {
but got no results.
Is this the correct way to do it or is there another way.
Thanks.
Adam

javadocs:
String's endsWith method takes a string argument.
endsWith
     public boolean endsWith(String suffix)
          Tests if this string ends with the specified suffix.
          Parameters:
               suffix - the suffix.
          Returns:
               true if the character sequence represented by the argument is a suffix of the character sequence
               represented by this object; false otherwise. Note that the result will be true if the argument is the
               empty string or is equal to this String object as determined by the equals(Object) method.
          Throws:
               NullPointerException - if suffix is null.

  • How we can find the last character in a string(Urgent Plz!)

    Gurus!

    Plz help!
    Many thanks!

    Use the substr() and length() functions -

    y := substr(x, length(x));

  • Want to single out the last character of a string

    There is a field where there are many strings of varying length. E.g.: AB001XUV, AB003XUK, DJ8933FXUV etc.
    From these strings I need to create a virtual column where only the last character is shown. So it shall be V, K, V for values from the above example.
    Can anyone please suggest me how to achieve this.

  • Any easier way to replace the last character of a string?

    this is what I got:

    tjgb005dy_01_31_01and I am not quite fond of it. it looks ugly and it is long.
    so, I wonder if you guys have better ideas?

    (Perhaps with replace there is no easier solution than the primary posted.)Well, look where I ended up...

  • Looking for the last item in a string set in a particular character style

    I should find each space that is the last character in a string set in a particular character style. For example, in the passage "123 456 789" (the underlined part here indicating a passage set in a particular character style), my ideal GREP search would yield a match after the digit 6.
    How do this?

    Excellent! This works perfectly. I have used your string with the bold character formatting, and replaced the matches with [nothing], set in None style.
    On second thought, I was surprised that it indeed had worked: why was the space replaced, and not deleted? Shouldn't I have used
    (?<!.)(\s)(?=\w)
    and replaced it with
    $2

  • How to remove only the last element of spreadsheet string

    I use path to string option to store image path into database and while retrieving the string is again converted into path but it gives out an error as the output of array to spreadsheet string gives out a tab at the end which is unable for the IMAQ read file to recognise.but when i use the path of the image directly into IMAQ readfile the image is opened . so how to remove the tab only at the end of output of the spreadsheet string(whose length can vary)? I have also attached my program with this.

    If you just want to remove the last character of a string just use the
    String Size function reduce the result by one and wire it together with
    the string to the Split String function.

  • Truncating last character in a string

    I am making a dialpad. It is just for display so I am using a
    string for the numbers selected. I am trying to make a back button
    that would clear the last number added. I tried mystring.length-1
    but that doesn't seem to be doing the trick. Is there a simple way
    to truncate the last character in a string, of variable
    length??

    Here's an example
    var someStr="asdfasdf saf asdf sadfas dfs fsa asf";
    while (someStr.length) {
    someStr = someStr.substring(0,someStr.length-1)
    trace(someStr);
    }

  • Strip the first character from a string

    i am trying to strip the leftmost character from a string
    using the following:
    <cfset Charges.DTL_CHG_AMT_EDIT =
    #Right(Charges.DTL_CHG_AMT_EDIT,Len(Charges.DTL_CHG_AMT_EDIT)-1)#>
    i keep getting the following error:
    Parameter 2 of function Right which is now -1 must be a
    positive integer

    > RemoveChars() much easier than Right()? How so?
    Semantically, if the object of the exercise is to *REMOVE
    CHARacters from a
    string* (which it is, in this case), it is simply better
    coding to use
    removeChars() rather than right(). That, and it's one less
    function call
    (the RIGHT() solution also requires a call to LEN() for it to
    work).
    So removeChars() is "easier" because it reflects the intent
    of the exercise
    directly, is simpler logic, is easier to read, and - I can't
    be arsed
    counting keystrokes - is probably less typing.
    That'd be how.

  • Select last character of a string

    Hello,
    I would like to select the last character of an address string. For example, in '165 John Ave W' -- select result 'W'. I tried to use RIGHT but it doesn't work. I'm using SQL Plus.
    SELECT RIGHT(ADDRESS,1) FROM addresses;
    ORA-00904: "RIGHT": invalid identifier
    I can't find the appropriate select statement to achieve the result I want. Ideas?
    Thanks!

    The SUBSTR function can take a negative start parameter, which counts in from the end of the string
    http://www.techonthenet.com/oracle/functions/substr.php - that should get you going, let me know if you get stuck.
