java - RESTful service -


i have write restful service client have problems functions because cant figure media type should @produces.

basically have few operations strings: counting words, finding index of substring, counting symbols , reversing string.

i have no problems reversing string, other 3 facing problem because seems can`t @produce int reason.

what type should use can @produce int can return it?

here java code:

 public int getnumberofwords(java.lang.string parameter) {   int words;          string [] sentence = parameter.split(" ");         words = sentence.length;          return words;       public int getnumberofsymbols(java.lang.string parameter) {         //todo implement method         //throw new unsupportedoperationexception("not implemented yet.");    return (int) parameter.chars()             .distinct()             .count();     public java.lang.string invertstring(java.lang.string text) {     //todo implement method     //throw new unsupportedoperationexception("not implemented yet.");      int i, len = text.length(); stringbuilder dest = new stringbuilder(len);  (i = (len - 1); >= 0; i--){     dest.append(text.charat(i)); }  return dest.tostring();     public int findsubstr(java.lang.string text, java.lang.string substr) {       return text.indexof(substr);

so first 3 functions problematic. tried @produces application/json type.

@produces("application/json") allow return json method of restfull has mapped object in client side, if simple thing string, or integer.

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.
