java class similar to Android Bundle class -

there useful class in android (at least me). bundle class allows put kind of pair key value. value can different established classes of objects.

for example:

bundle mbundle = new bundle(); mbundle.putint("number one", 1); mbundle.putboolean("true", true); 

there similar class in java?

not know of, it's easy reproduce hashmap:

public class bundle extends hashmap<string,object>{     public void putstring(string key, string str){       put(key, str);    }     public string getstring(string key){       object o = get(key);       if(o!=null && o instanceof string)          return (string) o;       return null;    }     public void putinteger(string key, int anint){       put(key, new integer(anint));    }     public integer getinteger(string key){       object o = get(key);       if(o!=null && o instanceof integer)          return (integer) o;       return null;    }     ...  }
