In brief: Properties make it easy to pass updates from the python side to the user interface Binding passes the changes that happened on the user interface to the python side. from kivy.app import App from kivy.uix.boxlayout import BoxLayout from kivy.lang import Builder from kivy.properti...

First, we create an empty map, and insert some elements into it: Java SE 7 TreeMap<Integer, String> treeMap = new TreeMap<>(); Java SE 7 TreeMap<Integer, String> treeMap = new TreeMap<Integer, String>(); treeMap.put(10, "ten"); treeMap.put(4, "fou...

First, we create an empty set, and insert some elements into it: Java SE 7 TreeSet<Integer> treeSet = new TreeSet<>(); Java SE 7 TreeSet<Integer> treeSet = new TreeSet<Integer>(); treeSet.add(10); treeSet.add(4); treeSet.add(1); treeSet.add(12); Once we hav...

Since TreeMaps and TreeSets maintain keys/elements according to their natural ordering. Therefor TreeMap keys and TreeSet elements have to comparable to one another. Say we have a custom Person class: public class Person { private int id; private String firstName, lastName; priva...

TreeMap and TreeSet are not thread-safe collections, so care must be taken to ensure when used in multi-threaded programs. Both TreeMap and TreeSet are safe when read, even concurrently, by multiple threads. So if they have been created and populated by a single thread (say, at the start of the pro...

Lets assume that we have a complex api, with many generic views and some generic viewsets. We want to enable PageNumberPagination to every view, except one (either generic view or viewset, does not make a difference) for which we want a customized case of LimitOffsetPagination. To achieve that we n...

CREATE INDEX ord_customer_ix ON orders (customer_id); By default, if we do not mention anything, oracle creates an index as a b-tree index. But we should know when to use it. B-tree index stores data as binary tree format. As we know that, index is a schema object which stores some sort of entry...
