Java Anonymous inner class.

Anonymous inner class.

• Is a class, which have no name and the class implementation is combined with an object instantiation of the class.
• Can be performed through implementing an interface or here as extending a class.
  Anonymous inner class example:

  public class AnonymousCar {   
    String _color;
    AnonymousCar(String col){
      _color=col;
    }
    Object obj = new Object() {          //  Anonymous inner class
      public String toString() {
        return "My color is "+_color+"!";
      }
    };
  
  
    public static void main(String[] args) {
      AnonymousCar myCar= new AnonymousCar("blue") ;      
      // instantiated object of class Anonymouscar
      System.out.println(myCar.obj);
    }
  }
  
  

  The result of this is:

  My color is blue!
