newline

问题 Let's say I wanted to print 5 lines. Which is the best method (for performance and readability). System.out.println(); System.out.println(); System.out.println(); System.out.println(); System.out.println(); or System.out.println("\n\n\n\n"); Is it a matter of preference or is one better than the other. It seems like it would save a lot of time using the second method. 回答1: There is a functional difference between the two. The first version outputs line breaks using the platform's preferred

问题 The Problem The below test case illustrates my issue. I have a JSF application which uses a HTML form in which I must use enctype="multipart/form-data" since I am using a file upload, see here. However when I use this encoding, newlines entered into my Textarea disappear when submitted to the server. The text area in result.xhtml always shows all of the text the user entered on index.xhtml on one line, regardless of any newlines the user put in. The output text always evaluates to "False" to

问题 First off, I'm using version 3.7.1 with a jQuery UI framework theme. I'm trying to figure out how to have a newline or even a <br /> render inside of a jqGrid cell. An example of what I'm looking to have happen: ________________________________________________________ Item 1 | some data | Applies to OS 1 Applies to OS 2 Applies to OS 3 Applies to OS 4 __________________________________________________________ Item 2 | some data | Applies to OS 1 _______________________________________________

问题 I want to convert this: <translation> 1 Sənədlər </translation> to <translation>1 Sənədlər</translation> in XML using C#. Please help me. Only translation tags. I tried this: XDocument xdoc = XDocument.Load(path); xdoc.Save("path, SaveOptions.DisableFormatting); But it does not remove the new lines between <translation> tags. 回答1: A new line is determined in the code by " \n " and possibly also " \r ". You can simply remove these: string xmlString = "<translation>\r\n1 Sənədlər\r\n<

问题 I have a gzip file with data field separated by commas. I am currently using PigStorage to load the file as shown below: A = load 'myfile.gz' USING PigStorage(',') AS (id,date,text); The data in the gzip file has embedded characters - embedded newlines and commas. These characters exist in all the three fields - id, date and text. The embedded characters are always within the "" quotes. I would like to replace or remove these characters using Pig before doing any further processing. I think I

问题 Is it possible to make a new line in the message notification? "\n" or "\r\n" just disappear but there's no new line set. I also tried var endOfLine = require('os').EOL; instead of \n. Doesn't work sadly. res.render('settings.ejs', { user: req.user, isAuthenticated: true, message: 'Changed User(s):' + changearray + '\n(Notice: You can\'t affect Users with higher Settingrights.)' }); Probabbly a stupid/easy question but I don't get it working... Thanks in advance. 回答1: You can use html tags.
