This method takes all strings in var-args format and all strings are passed as arguments in the method. The return string is received by appending all strings delimited by an argumentdelimiter. This method can join multiple string literals that are not yet in the form of a collection or arra...
The String.join method In the second example, we join strings with theString.joinmethod. Main.java void main() { var joined = String.join("/", "2024", "7", "1"); System.out.println(joined); } TheString.joinmethod internally uses theStringJoiner. var joined = String.join("/", "2...

The release argument specifies either the exact version string, or a list of version strings and ranges separated by spaces. A version string is the developer designation of the version number in the following form: 1.x.0_u (where x is the major version number, and u is the update versio...
If instead of XYZ, I have to write {java:field com.javax0.jamal.api#XYZ} any simple typo will be detected. If there is a field com.javax0.jamal.api#XYZ it is unlikely to have also com.javax0.jamal.api#XXY. With this approach, the docs-as-code workflow is extended. The ...
