Common Code block, construction block, static code block, and synchronization code block.

Class demo {// define the construction block system. out. println ("demo construction block");} static {// defines the static code block system. out. println ("static code block of demo");} public demo () // defines the constructor {system. out. println ("demo constructor") ;}} public class codedemo {{// define the constructor system. out. println ("codedemo construction block");} static {// defines the static code block system. out. println ("codedemo static code block");} public static void main (string [] ARGs) {new demo ();}}

Output result:

Static code block of codedemo
Static code block of demo
Demo construction block
Demo Constructor
