java - How is it that I am able to reference private fields of an instance inside a class? -


i have had explanation haven't been able find one. why code work? - why can private members of instance accessed? far know works when instance created in method inside original class.

public class myclass {     private int thing;      public myclass () {}      public myclass makeme () {         myclass myclass = new myclass();         myclass.thing = 1;         return myclass;     }  }

a private field can accessed class. you're still operating inside instance of myclass, private field visible , accessible without use of setter.

to bit more formal... jls 6.6.1 talks access.

here's abridged snippet, emphasis mine:

  • a member (class, interface, field, or method) of reference (class, interface, or array) type or constructor of class type accessible if type accessible , member or constructor declared permit access:

    • ...otherwise, if member or constructor declared private, access permitted if , if occurs within body of top level class (§7.6) encloses declaration of member or constructor.

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.
