In JVM

JVM , A Close Look 

Loading a class into JVM and It's life cycle , always has fascinated developers.
So was I , read some articles and here are my findings:

All drawing was done by me on rough paper while reading some article on JVM 

java.library.path

Sometime java needs to talk to native library i.e. dll or system lib. But how java going to load this native library?Adding this native lib in classpath will do ?
Java provides a way to load these native libraries by providing a property called java.library.path. This property is part of system environment.
Enough for talk. Let's get into action.

How to load these special native libraries? Java says do it through a special way by calling System.loadLibrary() ,If JVM doesn't find these libraries ,
it will throw UnsatisfiedLinkError.

How to set java.library.path? There are multiple ways to do it.

1) Through Java coding
System.setProperty("java.library.path","/path/to/library/dll")

2)Through command line
java -Djava.library.path=<path_to_dll> <main_class>

Or it can be done by setting VM property
-Djava.library.path="<path_to_dll>"

Happily Done ...
