Modifying a specific value under a child node in Firebase for android

I'm new to Firebase and currently I'm making my project using Firebase as backend. But I'm having this issue. I have my Firebase database structure like this:-

    root:
child1:
      value1:
      value2:
child2:
      value1:
      value2:

and so on. I want to edit/modify value2 under child 1. How can i do that. Any help would be appreciated.

Try this

I was facing some issues when using the above code ,finally after modification i got my solutions .This will modify your matching child's inside value

NOTE

users

+child1-value1

+child2-value1

DatabaseReference dbrefrence= FirebaseDatabase.getInstance().getReference();
    HashMap<String, Object> result = new HashMap<>();
    result.put("username", "COMPLETED");
    dbrefrence.child("users").child("child1").updateChildren(result);

DatabaseReference c1v2= FirebaseDatabase.getInstance().getReference().child("child1").child("value2");
c1v2.setValue("Value");
