would you please tell me how can i write this code correctly ?

@Override public boolean remove(Object o) { if (head == null) { return false; } else if(head.value.equals(o)) { } if(size ==1) { clear(); }

else { head = head.next; } size --; // TODO Auto-generated method stub return true; } else { Node prevO = head; while(prevO != tail && !prevO.next.value.equals(o)) { prevO = prevO.next; } if(prevO !=tail) { Node nextO =prevO.next.next; tail = prevO; } }
