Strange Code Sample without method name

Question

I have come across this code sample in a test. I answered that, it gives compile errors, coz theres a block of code without any method name, which prints "nothing".
But I tried to compile and run it, which put me in surprise. It compiled and executed. I did not understand how it worked and whats the concept behind this.
Can anyone dig into details or share knowledge if already know this.
Heres the code:
public class Test1
     public static void main(String args[]){
          new Test1();
          System.out.println("main...");
          new Test1("2222");
     Test1(){
          System.out.println("in constr 1");
     Test1(String s){
          System.out.println("in constr 2 :" + s);
          System.out.println("nothing...");
     static{
          System.out.println("static...");
}

Answer 1

>      {
          System.out.println("nothing...");
     static{
          System.out.println("static...");
     }Those are initializer blocks; The static block is executed when the
class has been loaded; the first block is executed just before a
constructor for that class is called.
