## Compiling a Module
### Compile and create class file in out folder
```bash
javac -d module-info.java
//example
javac -d out module-info.java
```
### Compile and create class file in out folder
```bash
javac -d --module-path
//example
javac -d out --module-path out github\hmasum18\jlinkTest\HelloWorld.java
```
### Run the class file from out folder
```bash
java --module-path --module /
//example
java --module-path out --module helloWorld/github.hmasum18.jlinkTest.HelloWorld
```
#### ouput
```
Mar 07, 2021 6:34:41 PM github.hmasum18.jlinkTest.HelloWorld main
INFO: hello world from masum
```
## Using jdeps to List the Dependent Modules
```bash
jdeps --module-path -s --module
//example
jdeps --module-path out -s --module helloWorld
```
#### output
```
helloWorld -> java.base
helloWorld -> java.logging
```
or
```bash
jdeps --list-deps --module-path -add-module
//example
jdeps --list-deps --module-path out --add-modules helloWorld
//example with javafx
jdeps --list-deps --module-path "lib\javafx-sdk-11.0.2\lib";"lib\gson-2.8.6.jar";"lib\jfoenix-9.0.10.jar";"out\production\CarShowRoomFrontend" --add-modules fontend
```
## Creating a Custom JRE with jlink
```bash
jdeps --module-path --add-modules --output
//example
jlink --module-path "%JAVA_HOME%\jmods";out --add-modules helloWorld --output customjrefolder
```
## Run code with custom JRE
```bash
"\java" --module-path -m
//example
"customjrefolder\bin\java" --module-path out -m helloWorld/github.hmasum18.jlinkTest.HelloWorld
```
## Creating Custom JRE with Launcher Scripts
```bash
jlink --launcher helloWorldLauncher=helloWorld/github.hmasum18.jlinkTest/HelloWorld --module-path "%JAVA_HOME%\jmods";out --add-modules helloWorld --output customJreLauncherFolder
```
