This document provides an overview of the Java programming language including how it works, its features, syntax, and input/output capabilities. Java allows software to run on any device by compiling code to bytecode that runs on a virtual machine instead of a particular computer architecture. It is an object-oriented language with features like automatic memory management, cross-platform capabilities, and a robust class library.

This presentation deals with pure object oriented concepts and defines basic principles of OOP's like Encapsulation , polymorphism , Inheritance and Abstraction.
An overview of object oriented programming including the differences between OOP and the traditional structural approach, definitions of class and objects, and an easy coding example in C++. This presentation includes visual aids to make the concepts easier to understand.
This extensive course covers all the topics which will definitely make you a Java Superstar. You can do almost anything in Java after this course. You will surely be a better programmer and better still a Elegant programmer after this course.

Cette formation UML va vous présenter les différents diagrammes de cette notation graphique ainsi que leur usage raisonnable.
Faire des diagrammes UML ne se résume pas effectivement à créer de chouette diagrammes qui ne serviront qu’à remplir les documents d’illustrations aussi beaux qu’inutiles. Il faut créer le diagramme lorsqu’il est nécessaire, avec justesse et en visant le maximum d’efficacité.
Après avoir présenté chacun des diagrammes, Fabien Brissonneau vous apprends à les utiliser dans un rôle de maîtrise d’ouvrage, puis dans un rôle d’analyse, enfin pour le concepteur.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

49. DISPLAY FILE CONTENTS import java.io.*; public class FileToOut1 { public static void main(String args[]) { try { FileInputStream infile = new FileInputStream("testfile.txt"); byte buffer[] = new byte[50]; int nBytesRead; do { nBytesRead = infile.read(buffer); System.out.write(buffer, 0, nBytesRead); } while (nBytesRead == buffer.length); } catch (FileNotFoundException e) { System.err.println("File not found"); } catch (IOException e) { System.err.println("Read failed"); } } }

51. WRITING DATA TO A FILE USING FILTERS import java.io.*; public class GenerateData { public static void main(String args[]) { try { FileOutputStream fos = new FileOutputStream("stuff.dat"); DataOutputStream dos = new DataOutputStream(fos); dos.writeInt(2); dos.writeDouble(2.7182818284590451); dos.writeDouble(3.1415926535); dos.close(); fos.close(); } catch (FileNotFoundException e) { System.err.println("File not found"); } catch (IOException e) { System.err.println("Read or write failed"); } } }
52. READING DATA FROM A FILE USING FILTERS import java.io.*; public class ReadData { public static void main(String args[]) { try { FileInputStream fis = new FileInputStream("stuff.dat"); DataInputStream dis = new DataInputStream(fis); int n = dis.readInt(); System.out.println(n); for( int i = 0; i < n; i++ ) { System.out.println(dis.readDouble()); } dis.close(); fis.close(); } catch (FileNotFoundException e) { System.err.println("File not found"); } catch (IOException e) { System.err.println("Read or write failed"); } } }
53. OBJECT SERIALIZATION Write objects to a file, instead of writing primitive types. Use the ObjectInputStream , ObjectOutputStream classes, the same way that filters are used.
54. WRITE AN OBJECT TO A FILE import java.io.*; import java.util.*; public class WriteDate { public WriteDate () { Date d = new Date(); try { FileOutputStream f = new FileOutputStream("date.ser"); ObjectOutputStream s = new ObjectOutputStream (f); s.writeObject (d); s.close (); } catch (IOException e) { e.printStackTrace(); } public static void main (String args[]) { new WriteDate (); } }
55. READ AN OBJECT FROM A FILE import java.util.*; public class ReadDate { public ReadDate () { Date d = null; ObjectInputStream s = null; try { FileInputStream f = new FileInputStream ("date.ser"); s = new ObjectInputStream (f); } catch (IOException e) { e.printStackTrace(); } try { d = (Date) s.readObject (); } catch (ClassNotFoundException e) { e.printStackTrace(); } catch (InvalidClassException e) { e.printStackTrace(); } catch (StreamCorruptedException e) { e.printStackTrace(); } catch (OptionalDataException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } System.out.println ("Date serialized at: "+ d); } public static void main (String args[]) { new ReadDate (); } }
