 # modularjava9example
 
 This demonstrates modules and custom jre creation in JAVA 9.
+
+#### create directory to hold modules
+````
+$ mkdir -p output/mlib
+````
+
+#### compile hello module and make hello.jar
+```
+$ javac -p output/mlib -d output/classes `find com.hello -name *.java`
+$ jar -c -f output/mlib/hello.jar  -C output/classes .
+$ /bin/rm -rf output/classes
+
+````
+
+#### compile helloclient module using hello module and make helloclient.jar
+```
+$ javac -p output/mlib -d output/classes `find com.hello.client -name *.java`
+$ jar -c -f output/mlib/helloclient.jar --main-class com.hello.client.HelloClient -C output/classes .
+$ /bin/rm -rf output/classes
+```
+
+
+#### program execution
+```
+$ java -p output/mlib -m com.hello.client/com.hello.client.HelloClient
+```
+
+
+#### Create custom JRE
+```
+$ /bin/rm -rf helloclientimage/
+jlink --module-path /Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home/jmods:output/mlib --add-modules com.hello --add-modules com.hello.client --output helloclientimage --launcher=helloclient=com.hello.client
+```
+#### list custom jre modules 
+```
+$ ./helloclientimage/bin/java --list-modules
+```
+
+#### custom jre exection
+```
+$ ./helloclientimage/bin/java -m com.hello.client
