  • TinyMCE empty link popup

    - by silent1mezzo
    When I try to insert a link using the TinyMCE link plugin all that happens is I get an empty popup box.

  • Method to concatenate 2 Strings in Java

    - by GooF
    I have a method in Java that concatenates 2 Strings. It currently works correctly, but I think it can be written better. public static String concat(String str1, String str2) { String rVal = null; if (str1 != null || str2 != null) { rVal = ""; if (str1 != null) { rVal += str1; } if (str2 != null) { rVal += str2; } } return rVal; } Here are some of the requirements: If both str1 and str2 are null, the method returns null If either str1 or str2 is null, it will just return the not null String If str1 and str2 are not null, it will concatenate them It never adds "null" to the result Can anyone do this with less code?

  • Parsing through Arabic / RTL text from left to right

    - by Dan W
    Let's say I have a string in an RTL language such as Arabic with some English chucked in: string s = "Test:?????;?????;?????;a;b" Notice there are semicolons in the string. When I use the Split command like string[] spl = s.Split(';');, then some of the strings are saved in reverse order. This is what happens: ??Test:????? ????? ????? a b The above is out of order compared to the original. Instead, I expect to get this: ?Test: ????? ????? ????? a b I'm prepared to write my own split function. However, the chars in the string also parse in reverse order, so I'm back to square one. I just want to go through each character as it's shown on the screen.

Does someone know? Thank you.

The sql works select * from ebigusertim where id='blah'. It returns 2 distinct rows. When i query the data using hibernate, it appears that the object memory is not being allocated for each entry in the list. Thus, i get 2 entries in the list with the same object. Criteria userCriteria = session.createCriteria(EbigUser.class); userCriteria.add(Restrictions.eq("id", id)); userlist = userCriteria.list();

    - by Esmond
    Hi i encountered this problem whereby when i initialized my String[], there seems to be a null in the String[] before i do anything. How do i initialized the String[] to be completely empty,i.e. without the null at the start? The output for the following code is: nullABC nullABC nullABC nullABC nullABC public static void main(String[] args){ String[] inputArr = new String[5]; for (int i = 0; i< inputArr.length; i++){ inputArr[i] += "ABC"; } for (int i = 0; i< inputArr.length; i++){ System.out.println(inputArr[i]); } } }
