java - Printing a HashMap that contains of String and List of Objects -


how can print hashmap containts of string , list of objects? 

hashmap<string, list<object>> map = new hashmap<string, list<object>>();

each object has name , key value need like:

stringfirst = [ firstobject 15, second object 31, thirdobject 16] stringsecond = [ fourthobject 15, fifthobject 31, sixthobject 16]      public static class graph {      public class edge extends graph {         string edgename;         int time;          edge(string edgename, int time){             this.edgename = edgename;             this.time = time;         }          public void out(){             system.out.println(this.edgename);             system.out.println(this.time);         }     }

try out printing map:

for(map.entry<string, arraylist<edge>> e : map.entryset()){    for(edge e1 : e.getvalue())       system.out.println(e.getkey() + " = "+ e1.out()); }

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.
