public class Anony{
  private int x = 6;
  public static void main(String[] args){
    int x =4;
    new Anony().new Cell().doSth();
  }
  class Cell{
    coid doSth(){
      System.out.println("print key "+x);
    }
  }
}

The result is "print key 6".
line 5 "new Anony()" and "new Cell()" is the syntax to create anonymous object of Anony class and Cell class.
