If there are these two keywords then they must have their own meaning. So I want to know what makes them different and what is their code? A line feed means moving one line forward. The code is \n . A carriage return means moving the cursor to the beginning of the line. The code is \r . Windows editors often still use the combination of both as \r\n in text files. Unix uses mostly only the \n . The separation comes from typewriter times, when you turned the wheel to move the paper to change the line and moved the carriage to restart typing on the beginning of a line. This was two steps. Since

问题 As per subject... 回答1: \n is Unix, \r is Mac, \r\n is Windows. Sometimes it's giving trouble especially when running code cross platform. You can bypass this by using Environment.NewLine . Please refer to What is the difference between \r, \n and \r\n ?! for more information. Happy reading 回答2: The Difference There are a few characters which can indicate a new line. The usual ones are these two: * '\n' or '0x0A' (10 in decimal) -> This character is called "Line Feed" (LF). * '\r' or '0x0D'

问题 "\n" and "\r\n" , tested in text message sent by telegram bot, to create line break. Instead of showing line break, underline _ will appear after using them.

Carriage Return\Line feed in Java

由 試著忘記壹切 提交于 2019-11-27 10:01:31
问题 I have created a text file in Unix environment using Java code. For writing the text file I am using java.io.FileWriter and BufferedWriter . And for newline after each row I am using bw.newLine() method (where bw is object of BufferedWriter ). And I'm sending that text file by attaching in mail from Unix environment itself (automated that using Unix commands). My issue is, after I download the text file from mail in a Windows system, if I opened that text file the data is not properly aligned

How to get carriage return without line feed effect in Eclipse console?

If I System.out.print("something\r"); at console, I have cursor back at the beginning of line, and finally after System.out.print("something\r"); System.out.print(" any\r"); I have anything typed. But at Eclipse console I get something anything as if it treated \r as CR/LF. How can I setup this? As Nishant already pointed out in the comments, you've found a bug here. This bug initially was reported in 2004 (>9 years ago!?!!) and this bug seems not to be fixed very soon (or ever). I tested it on several Eclipse version, even on Eclipse Juno SR2 , and the bug is still there. It finally seems to

How to find out which line separator BufferedReader#readLine() used to split the line?

问题 I am reading a file via the BufferedReader String filename = ... br = new BufferedReader( new FileInputStream(filename)); while (true) { String s = br.readLine(); if (s == null) break; ... } I need to know if the lines are separated by '\n' or '\r\n' is there way I can find out ? I don't want to open the FileInputStream so to scan it initially. Ideally I would like to ask the BufferedReader since it must know. I am happy to override the BufferedReader to hack it but I really don't want to

Why does Windows use CR LF?

问题 I understand the difference between the two so there's no need to go into that, but I'm just wondering what the reasoning is behind why Windows uses both CR and LF to indicate a line break. It seems like the Linux method (just using LF) makes a lot more sense, saves space, and is easier to parse. 回答1: Historically when using dot-matrix printers teletypes CR would return the carriage to the first position of the line while LF would feed to the next line. Using CR+LF in the file themselves made

Writing a new line to file in PHP (line feed)

由 青春壹個敷衍的年華 提交于 2019-11-26 03:34:01
问题 My code: $i = 0; $file = fopen(\'ids.txt\', \'w\'); foreach ($gemList as $gem) { fwrite($file, $gem->getAttribute(\'id\') . \'\\n\'); $gemIDs[$i] = $gem->getAttribute(\'id\'); $i++; } fclose($file); For some reason, it\'s writing \\n as a string, so the file looks like this: 40119\\n40122\\n40120\\n42155\\n36925\\n45881\\n42145\\n45880 From Google\'ing it tells me to use \\r\\n , but \\r is a carriage return which doesn\'t seem to be what I want to do. I just want the file to look like this:
