Concrete class is a class with implementation for all the methods in it. Concrete class defines all the abstract methods of an abstract class which it is extending. Object class is a concrete class.

A concrete class in java is a class which has implementation of all of its inherited members either from interface or abstract class.

  1. public abstract class A {

  2.      public abstract void test();

  3. }


  5. interface B {

  6.      public void test2();

  7. }


  9. public class C extends A implements B {

  10.        public void test() {

  11.             System.out.print("Abstract implementation");

  12.         }


  14.       public void test2() {

  15.            System.out.print("Interface implementation");

  16.        }

  17. }
