What is this line of code means???

Question

Hi have a general question, I am not sure if it right place to ask. But I will be grateful if some body could help on this one. I could not figure out what is that line of code (**) is doing or what does it mean. I gave sample implementation here.
Public class Decoder{
InputStream in
Public Decoder(InputStream in){
This.in = in;
String st = somefunction(in)
public static Xval decode(InputStream in){
return new Decoder(in).decode(); **
What I don�t understand that what is line of Code do �return new Decoder(in).decode(); � I have never seen this kind of implementation. The return type is Xval but the function is retrunin t object of this (Decoder) type. And what is Decoder(in).decode() when function decode() is doing nothing except returning a object???
Thank you

Apparently, the Decoder class has a method called decode() that returns a Xval object. The line is equivalent toDecoder d =  new Decoder(in);
Xval xv = d.decode();
return xv;
