Windows: which java version do I use?

 On windows oracle java uses quite a complicated way to find the java executable.

> echo %PATH%
C:\Program Files (x86)\Common Files\Oracle\Java\javapath;...

Starting from javapath it uses quite a complex mechanism, which well explained in this stackoverflow answer.

Ultimately the windows registry is used, like I also explained earlier.

When you frequently have to hop from one Java version to another, it is a good idea to store the path to your java binaries in the JAVA_HOME environment variable and prepend that to your windows path.

Java 15 new features

 On september 15th Java SE 15 is released, along with some preview features, these are the new features:

Hidden classes

Classes that are dynamically generated by frameworks that can not be discovered (and thus not directly used) through reflection.

Text blocks

Support for strings containing newlines. Text blocks are delimited using """ (triple double quote).

Indent and trailing spaces are removed from such strings (i.e. you can paste in indented code, the blanks will be removed).

Normal string escape characters (\n, \t,...) apply, and some extra escape characters are added:

\

\ at the end of a line: escapes the newline (the newline will not appear in the final string)

\s

A hard space. This space (and any preceding spaces) will not be removed, even if it is a trailing space.
