Java 8 sort multiple objects

   public class B {
              private String name;
              private String  value;

             //Setters and Get
       }        
       public class C {
             private String name;
             private String  value;
        //Setters and Get Methods
       }
        public class D {
             private String name;
             private String  value;
             //Setters and Get
        }
        public class A {
              private B b;
              private C c;
              private D d;
            // Setters and Get
         }
        public class  Example{
          List<A> a = new Array List<A>();
            //Lets assume a  will contain objects of class B, C and D
           a .sort( Comparator.comparing(A::getB().getName).thenComparing(A::getC().getName));

         }

Sort field from one pojo , then sort field by next pojo. Need to understand how to sort in this situation. Can we use Comparator.comparing ()in this case?

You can't use method refences like that, but you could just use lambda expressions:

a.sort(Comparator.comparing((A x) -> x.getB().getName())
                 .thenComparing(x -> x.getC().getName()));
