create a class > app.java
compile it > javac app.java
what goes on?:
JVM loads class.
Static members are initialized?
JVM goes to the main method.
Object is declared in main: App myApp;
Object creation: myApp = new App();
New is envoked.
New operator allocates memory.
New operator calls the super ctor.
New operaator calls the original ctor.
Constructor creates the "object."
Constructor body is not yet executed though.
Constructor initializes all instance variables to 0,null or false.
Constructor body is now executed.
Is this a good "loose" interpretation?

hope it helps!
It is sorta covered in the JavaRanch Style Guide.
