问题 I have a backing bean containing a field creditCard which can have two string values y or n populated from the DB. I would like to display this in checkbox so that y and n gets converted to boolean . How can I implement it? I can't use a custom converter as getAsString() returns String while rendering the response whereas I need a boolean . 回答1: The <h:selectBooleanCheckbox> component does not support a custom converter. The property has to be a boolean . Period. Best what you can do is to do

问题 I'm a bit lost. For a project, I need to convert the output of a hash-function (SHA256) - which is a byte array - to a String using base 36. So In the end, I want to convert the (Hex-String representation of the) Hash, which is 43A718774C572BD8A25ADBEB1BFCD5C0256AE11CECF9F9C3F925D0E52BEAF89 to base36, so the example String from above would be: 3SKVHQTXPXTEINB0AT1P0G45M4KI8U0HR8PGB96DVXSTDJKI1 For the actual conversion to base36, I found some piece of code here on StackOverflow: public static

问题 You know, like A = 1, B = 2 etc. I could just make a long list of if-thens, but maybe there's already a module for it. Bonus if it works like it does in "Excel Coordinates" where AA = 27 and continues. (Does this count as base26 numbers?) 回答1: def foo(c): return ord(c) - 64 foo('A') 1 foo('B') 2 off the top of my head :p 回答2: from string import ascii_uppercase letterKey = dict(list(zip( ascii_uppercase, range(1, 27)))) And as for the excel cords: geExceltValue = lambda string: sum([26**i *

问题 I have an ms word doc file that i'm converting to an html document using apache poi. this is the code i'm running InputStream input = new FileInputStream (path); HWPFDocument wordDocument = new HWPFDocument (input); WordToHtmlConverter wordToHtmlConverter = new WordToHtmlConverter (DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument() ); List<Picture> pics = wordDocument.getPicturesTable().getAllPictures(); if (pics != null) { for (int i = 0; i <pics.size(); i++) { Picture

问题 I knwo there is already an question like this. But its solution was not suitable for me because with the Sehellfolder Methode you can only get 16x16 and 32x32 sized icons. I have extracted a HICO with size of 256x256 and want to convert it into and Java Image like BufferedImage. I found and method for it to. But it does not work properly: public static BufferedImage getIcon(final WinDef.HICON hIcon,int ICON_SIZE,short ICON_DEPTH,int ICON_BYTE_SIZE) { final int width = ICON_SIZE; final int
