JEP proposed to target JDK 21: 445: Unnamed Classes and Instance Main Methods (Preview)

[Mark Reinhold]

The following JEP is proposed to target JDK 21:

  445: Unnamed Classes and Instance Main Methods (Preview)
       https://openjdk.org/jeps/445

  Summary: Evolve the Java language so that students can write their
  first programs without needing to understand language features designed
  for large programs.  Far from using a separate dialect of Java,
  students can write streamlined declarations for single-class programs
  and then seamlessly expand their programs to use more advanced features
  as their skills grow.  This is a preview language feature.

Feedback on this proposal from JDK Project Committers and Reviewers [1]
is more than welcome, as are reasoned objections.  If no such objections
are raised by 23:59 UTC on Friday, 12 May, or if they’re raised and
then satisfactorily answered, then per the JEP 2.0 process proposal [2]
I’ll target this JEP to JDK 21.
