Я прочитал о модели памяти JVM и запутался в следующем:

Does the JVM store the .class instance in its memory. If yes then in which area. Is it like as soon as the class is loaded,the JVM generated machine level code and then starts executing the machine code instructions and then only the objects are created on heap and method area is populated. The perm gen etc areas store the byte code or the machine level code? perm gen vs method area

Буду очень признателен за любую помощь по этой теме.

Благодарю.
