Because Reference for Woman is woman and you have to hold this reference in man.wife so it wii be assigned as man.wife=woman //if you remember assignment operator (it will hold the ref of woman in it) Similary for the next Hope its fine Further to clarify try to print System.out.println(woman); System.out.println(man.wife); and observe the output. Further try to print the value as you have tried see the difference hope it will help Enjoy!
