The List interface is implemented by different classes. Each of them has its own way for implementing it with different strategies and providing different pros and cons. Classes implementing List These are all of the public classes in Java SE 8 that implement the java.util.List interface: Abs...
Many biological questions can be translated into a DNA sequencing problem. For instance, if you want to know the expression level of a gene you can: copy its mRNAs into complementary DNA molecules, sequence each of the resulting DNA molecules, map those sequences back to the reference genome, and th...
LRU Cache The following example code demonstrates a possible implementation of the LruCache class for caching images. private LruCache<String, Bitmap> mMemoryCache; Here string value is key for bitmap value. // Get max available VM memory, exceeding this amount will throw an // OutOfMem...
Scope is used as the "glue" that we use to communicate between the parent controller, the directive, and the directive template. Whenever the AngularJS application is bootstrapped, a rootScope object is created. Each scope created by controllers, directives and services are prototypically ...
On the server: var express = require('express'); var socketio = require('socket.io'); var app = express(); var server = http.createServer(app); var io = socketio(server); io.on('connect', function (socket) { socket.on('userConnected', socket.join); socket.on('userDisconnected', socke...
These are my VirtualBox settings: OS Type: Linux 2.6 (I've user 64bit because my computer can support it) Virtual hard drive size: 4Gb Ram Memory: 2048 Video Memory: 8M Sound device: Sound Blaster 16. Network device: PCnet-Fast III, attached to NAT. You can also use bridged adapter, but you...
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...
Most kivy apps start with this structure: from kivy.app import App class TutorialApp(App): def build(self): return TutorialApp().run() There is several way to go from here : All the codes below (except example 1 and 3) have the same widget and similar features, but show diffe...
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...

Before reading some code, it is important to undersand the main concepts that will help to program applications using json. Serialization: Process of converting a object into a stream of bytes that can be sent through applications. The following code can be serialized and converted into the previ...
