design patterns - Java: Take anonymous class outside -


i have situation presented below:

class c1 {      public static void main(string[] args) {         object o = // new object of class         delegate(new c2() {             // c2 abstract class or interface             public void delegatelogic() {                 object my_o = o;  // refrences main's local variable                 // huge method body                 // object o local main required here               }         });     }      private void delegate(c2 c2) {         // method body     } }

the body of delegatelogic() turning out big. code maintainability :

  1. i want create concrete class c2 , keep outside, while still having way use object o in main method.
  2. also, instance of c2 supposed serializable , unfortunately object o not serializable. so, not want create member object in c2 passing object o in constructor.

any ideas?

if want c2 able serialized, declare o transient. however, need accept fact o null if got serialized/deserialized unless manage serialize manually somehow.

public class x extends c2 {     private transient object o;      public x(object o) {         this.o = o;     }      public void delegatelogic() {         object my_o = o;  // refrences main's local variable         // huge method body         // object o local main required here       } }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
