Is there anything called JVM launcher in java? What is JVM Launcher?
A JVM Launcher is a program that starts a JVM running. java.exe is an example of one, but you don't have to use java.exe to start a Java application. You can write your own JVM Launcher. Here's one example of how to do it.
One of the interesting features your own JVM launcher could have is that it's free to run Java code in other ways than by invoking the main method of a particular class. It could call some other method, or it could even call several methods in different classes.
