Question

I am trying to run below code using jdk-9 but facing problem when compile using command

Command

Answer 1

Seems like you are compiling with non-jigsaw jdk build here... here is the link were they are jigsaw

With that compiler these same samples that you have compile just fine on my laptop.

This is how java -version looks like for project jigsaw:

java version "9-ea"
Java(TM) SE Runtime Environment (build 9-ea+153-jigsaw-nightly-h6003-20170124)
Java HotSpot(TM) 64-Bit Server VM (build 9-ea+153-jigsaw-nightly-h6003-20170124, mixed mode)

EDIT It works with both jigsaw and non-jigsaw build. I have just tried it (build 149)

EDIT2 So i've tried with jdk-9 build 153 and here is what I got:

javac -d mods module-info.java Modules.java
module-info.java:1: warning: [module] module name module1 should avoid terminal digits
module module1 {
      ^
1 warning

removing the "1" and running the same command compiled OK and mods directory was created with both class files compiled just fine.
