java - Retrive Nested Hashmap data from yaml file -

i have following yaml data

networklayerconfig:      eventmap: !!map       !!int 100 :          !!int 1 : idling         !!int 2 : accepting 

i use yamlbean read data following class

class networklayerconfig {     private hashmap<integer, map<integer, string>> eventmap; } 

i trying access every key , associated value pair.

if try access these data when declared in java class like

myhashmap = new hashmap<integer, map<integer, string>>(); myhashmap.put(100, new hashmap<integer, string>()); myhashmap.get(100).put(1, "idling"); myhashmap.get(100).put(2, "accepting"); 

using following code

for (map.entry<integer, string> onemap : myhashmap.get(100).entryset()) {     system.out.println(onemap.getkey());     system.out.println(onemap.getvalue()); } 

since have read value 100 yaml file (i.e, during runtime) don't know how access every data.

i solved problem access every value in hashmap

iterator<?> iterator = myparenthashmap.entryset().iterator();         while (iterator.hasnext()) {             entry myentry = (entry) iterator.next();             system.out.println(myentry.getkey() + " : ");             hashmap<integer, string> childhashmaps = ((hashmap<integer, string>) myentry.getvalue());             system.out.println("{");             (map.entry<integer, string> childhashmap : childhashmaps.entryset()) {                 system.out.print(childhashmap.getkey() + " : ");                 system.out.println(childhashmap.getvalue());             }             system.out.println("}");         }
