Thread: Java programing style

Does each of these style have a name? I only know that the 2nd one is call " Top down" but no idea what the 1st and 3rd style call. Thanks

public class HelloWorldV1
{
//main method
public static void main(String[] args)
{
    System.out.println("Hello, Virtual World!");
    System.out.println("It is a great day for programming.");
}
}

public class HelloWorldV2
{
//print two lines of text
public static void printTwoLines( )
{
     System.out.println("Hello, Virtual World!");
     System.out.println("It is a great day for programming.")
}
//main method
public static void main(String [] args)
{
     printTwoLines();
}
}

public class HelloWorldV3
{
//default constructor
HelloWorldV3()
{
}
//print two lines of text
public void printTwoLines( )
{
     System.out.println("Hello, Virtual World!");
     System.out.println("It is a great day for programming.");
}
//main method
public static void main(String [] args)
{
     HelloWorldV3 hello = new HelloWorldV3( );
     hello.printTwoLines();
}
}

It is better now?
