问题 I've been wondering if for example: JTextPane chatTextArea = new JTextPane(); s.replaceAll(":\\)", emoticon()); public String emoticon(){ chatTextArea.insertIcon(new ImageIcon(ChatFrame.class.getResource("/smile.png"))); return "`"; } can put a picture and a "`" everywhere ":)" is found. When I run it like this if s contains a ":)" then the whole s gets replaced just by the icon. Is there a way to do it? 回答1: Here is a small example I made (+1 to @StanislavL for the original), simply uses

replace() and replaceAll() in Java

问题 The following code uses the replace() method of the String class in Java. String a = "abc/xyz"; System.out.println(a.replace("/", "\\")); / in the given String a is being replaced with \ . The same thing is wrong, if we use the replaceAll() method as follows. System.out.println(a.replaceAll("/", "\\")); It causes the exception java.lang.StringIndexOutOfBoundsException to be thrown. It requires two additional backslashes \ like the following, since replaceAll() uses a regex which is not the

How to preserve newlines while reading a file using stream - java 8

try (Stream<String> lines = Files.lines(targetFile)) { List<String> replacedContent = lines.map(line -> StringUtils.replaceEach(line,keys, values)) .parallel() .collect(Collectors.toList()); Files.write(targetFile, replacedContent); } I'm trying to replace multiple text patterns in each line of the file. But I'm observing that "\r\n"(byte equivalent 10 and 13) is being replaced with just "\r"(just 10) and my comparison tests are failing. I want to preserve the newlines as they are in the input file and don't want java to touch them. Could anyone suggest if there is a way to do this without

remove substring in a string without using regex (cannot use replaceAll)

由 放肆的年华 提交于 2019-12-04 05:57:01
问题 I need to remove some substrings in strings (in a large dataset). The substrings often contain special characters, like these: ., ^, /,... and replaceAll() would treat them as special characters for regex, such as a dot would match any character, which is not really what I want. Is there other functions to do the "replace" without treating the first argument as regex? 回答1: Just use String.replace(). It functions the same way, but it deals with escaping the special characters internally to

Java String.replaceAll() refer the latest found group

由 眉间皱痕 提交于 2019-12-04 05:40:29
问题 Javadoc says $1, $2, etc. can be used to reference the match groups, but how does one reference the latest found group in the replacement string when using String.replaceAll() ? I.e. there's a string "aaabbbaa" and a regex "a+" , and I want to be able to do something like s.replaceAll("a+", "$\n") to get "aaa\nbbbaa\n" , but Java gives me the Illegal group reference . 回答1: s.replaceAll("(a+)", "$1\n") should work: jshell> String s = "aaabbbaa" s ==> "aaabbbaa" jshell> s.replaceAll("(a+)", "$1
