How to invoke a java static method from jruby -


how do this?

include java thread.currentthread.sleep 3

i saw posting several years ago did not directly answer question.

thx

either:

java::javalang::thread::sleep 3

or 

java::javalang::thread.sleep 3

(note static call sleep() on thread causes current thread sleep, no need call currentthread(), , sleep time in millisecond).

here example (if use jruby prior 1.7, need add require 'java'):

t = java::javalang::thread.new   puts "hi."   java::javalang::thread::sleep 3000   puts "done." end t.start

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
