Fetch value from a set object in java -

i'm iterating set object find particular value. there short way fetch instead of iterating it? here code

for(tree t : assignedtrees) {      println t.treename; }

the above code return expected value.

assignedtrees set object

set<tree> assignedtrees = new hashset<tree>() println assignedtrees return  [tree{id=null, treename=mango}]

can fetch treename instead of iterating?

you can fetch object set calling myset.get(object). however, in case wish fetch object based on 1 of attributes. best way map - e.g.

map<string, tree> trees = new hashmap<>(); trees.put(treeobject.treename, treeobject);  tree mytree = trees.get("mytreename");

note if you're putting own objects sets or maps, must override equals , hashcode methods, or strange things happen.
