i've been struggling days, , wasn't able find info on or how achieve that. great.

you can create method return matching nodes. can iterating on nodes in tree , check if there names matches 1 in set.

   public java.util.list<treepath> find(defaultmutabletreenode root, set<string> s) {         java.util.list<treepath> paths = new arraylist<>();         @suppresswarnings("unchecked")         enumeration<defaultmutabletreenode> e = root.depthfirstenumeration();         while (e.hasmoreelements()) {             defaultmutabletreenode node = e.nextelement();             if (s.contains(node.tostring())) {                 paths.add(new treepath(node.getpath()));             }         }         return paths;     } 

you can call method passing tree node , set of strings. please note need cast root defaultmutabletreenode because getroot returns object.

java.util.list<treepath> treepaths=   find((defaultmutabletreenode)tree.getmodel().getroot(), someset); 

then iterate on treepaths , invoke removeselectionpath deselect nodes

    (treepath treepath : treepaths) {         tree.getselectionmodel().removeselectionpath(treepath);     }
