When a class gets loaded? What happens when the constructor is called? When is static block gets called? What is an instance initializer block?

Understanding the order of operation for how a class gets loaded is really important.

Always remember Static blocks and members load before any instance members get loaded. Anything static gets loaded top to bottom.
Constructors always make a call to super() before doing their thing.


When you do things right, people won't be sure you've done anything at all.
