//System.out.println("objcobject의 object속성variable cc의 값은 " + (c)j.cc);  //X

//System.out.println("objcobject의 object속성variable cc의 값은 " + ((c)j).cc);

B jj =new B();

System.out.println("objcobject의 object속성variable aa의 값은 " + jj.aa);

////C c1=(C)jj;

//C c1 = (C)jj; //explicit type casting BUT 여기 example로는 call?은 안됨!

//System.out.println("objcobject의 object속성variable aa의 값은 " + c1.aa);

//System.out.println("objcobject의 object속성variable bb의 값은 " + c1.bb);

//System.out.println("objcobject의 object속성variable cc의 값은 " + c1.cc); //error

}

}

//자기자신 =this 상위=super

//objcreference variable   

// -> objectreference variable -> a class = "1" + default constructor (objectreference variable)에 추가 = "a()"

// -> b class = "2" + default constructor (objectreference variable)에 추가  = "b()"

// -> c class = "3" + default constructor (objectreference variable)에 추가  = "c()"

//object화 -> object의 address value을   objcreference variable에 저장!
