Whenever a new JVM is started by typing java MyMainClass, the "bootstrap class loader" is responsible for loading key Java classes like java.lang.Object and other runtime code into memory first. The runtime classes are packaged inside of the JRE\lib\rt.jar file.

A class loader starts by being a subclass of java.lang.ClassLoader. The only abstract method that must be implemented is loadClass(). The flow of loadClass() is as follows:

Verify class name.
Check to see if the class requested has already been loaded.
Check to see if the class is a "system" class.
Attempt to fetch the class from this class loader's repository.
Define the class for the VM.
Resolve the class.
Return the class to the caller
