Static versus instance initializers blocks of a java class

class Foo {

       /* Static initializer: executes when the class is loaded. */

       static {

              System.out.println("class Foo loaded!");

       }

       /* Instance initializer: excutes when calling new Foo(),

       BEFORE anything inside the Foo constructor */

       {

              System.out.println("new instance of Foo about to be created!");

              // has access to internal Foo methods:

              print("instance initializer has access to internal methods!");

       }

       /* Constructor */

       public Foo() {

              System.out.println("Foo constructor statements!");

       }

       public void print(String msg) {

              System.out.println(msg);

       }

       static public void main(String[] args) {

              new Foo();

              System.out.println(" ");

              new Foo();

       }
