I am turning from vim to emacs ,and the first step seems a little
difficult~~

a problem is the indent style of emacs default is just like
public void helloWorld()
{
  if(today.weather == find)

    {
      System.out.println("oh~ a fine day~");
    }
}
but actually the style I expect is 
public void helloWorld()
{
  if(today.weather == find)
  {
    System.out.println("oh~ a fine day~");

  }
}
you may notice that the position of { } of the if loop has been changed
to be accord with that if statement, seems this is the recommand code 
style of Sun's documentation
but I can't find how to change emacs's default indent style to this
