![]() ![]() The easiest way to start the provided webserver is the jwebserver command. Through JDK Enhancement Proposal 408, Java also offers this possibility as of version 18. Simple Web ServerĪlmost all modern programming languages allow starting up a rudimentary HTTP server to, for example, quickly test some web functionality. This method returns the specified fallback value instead of throwing an IllegalCharsetNameException or an UnsupportedCharsetException if the character set name is unknown or the character set is not supported. Not part of the above JEP and not defined in any other JEP is the new method Charset.forName(String charsetName, Charset fallback). ![]() Charset.forName() Taking Fallback Default Value ![]() The default character set for an invalid "file.encoding" input is always UTF-8 as of Java 18 or corresponds to the native encoding up to Java 17. The system property "file.encoding" is still "default" – but at this point, we would also see any other invalid input. Native.encoding : UTF-8 Code language: plaintext ( plaintext ) Since Java 17, the system property "native.encoding" can be used to read the encoding, which – before Java 18 – would be the default encoding if none is specified: The current default encoding can be read at runtime via faultCharset() or the system property "file.encoding". The best way is always to set "-Dfile.encoding" to UTF-8 or omit it altogether. Quite possibly, "file.encoding" will be deprecated in the future and later removed to eliminate the remaining potential source of errors (methods that respect the default encoding vs. All other values lead to unspecified behavior. The fact that the Files methods ignore the configured default encoding will not be changed by JEP 400.Īccording to the documentation, only the values "UTF-8" and "COMPAT" should be used anyway, with UTF-8 providing consistent encoding and COMPAT simulating pre-Java 18 behavior. The default encoding will always be UTF-8 regardless of the operating system, locale, and language settings.Īlso, the system property "file.encoding" will be documented – and we can use it legitimately. With JDK Enhancement Proposal 400, the problems mentioned above will – at least for the most part – be a thing of the past as of Java 18. ハッピーコーディング!
