Static Initializers
Any static initializers declared in a class are executed when the class is initialized
and, together with any field initializers for class variables, may be used to
initialize the class variable of the class
StaticInitializer:
static Block

• It is a compile-time error for a static initializer to be able to complete abruptly
  with a checked exception .
• It is a compile-time error if a
  static initializer cannot complete normally
• The static initializers and class variable initializers are executed in textual
  order.
  
• Use of class variables whose declarations appear textually after the use is  sometimes restricted, even though these class variables are in scope.


• If a return statement appears anywhere within a static initializer,
  then a compile-time error occurs.
