问题 I have a list of String that contains word. Some words have apostrophe at the beginning or/and at the end like this: apple 'orange banana' joe's I want to delete only the apostrophes at the beginning and at the end of the words like this: apple orange banana joe's I have tried with the following regex but it doesn't work: myString.replaceAll("((?<=^)'|'(?=$))", ""); It does not work in IntelliJ: But it works with regex101.com: Why the regex dosen't works and how can I remove the beginning and

问题 I have project, that have 4 Git Roots: Project , Project-commons , Project-ui and Data Model . Due to certain config, I need to put Project-commons , Project-ui and Data Model into Project dir. But this resulted in IDEA highlighting Project-commons , Project-ui and Data Model as red folders. Git still works for me (as well as Maven), I didn't have any merge errors. What does that red highlight mean? Using "Synchronize" option to them helps, until I restart IDEA. I believe it has to do

问题 The following code String[] values = ... .... Map<String, Object> map = new HashMap<>(); for (int i = 0; i < values.length; i++) { map.put("X" + i, values[i]); } is converted by IntelliJ to: Map<String, Object> map = IntStream.range(0, values.length) .collect(Collectors.toMap( i -> "X" + i, i -> values[i], (a, b) -> b)); which can be shortened to Map<String, Object> map = IntStream.range(0, values.length) .collect(Collectors.toMap( i -> "X" + i, i -> values[i])); The 2 stream versions don't

问题 Either I'm missing some core concept buried deep within some documentation (Spring, Spring Boot, H2, HSQLDB, Derby, IntelliJ) or I've been staring at this for too long. I have a Spring Boot project going. Tried using and initializing an H2 DB at first, tried connecting to it in IntelliJ only to realize that I might not be able to easily browse the db without giving up my firstborn child (Connect to H2 database using IntelliJ database client). So I moved to DerbyDB. Same thing - db root folder
