Presentation on C++ Programming Languagesatvirsandhu9
It consists information about c++ programming language which is a object oriented language. This presentation is very useful for those who want to learn c++ from beginning.
Here I discuss about Java programming language and easiest way to solve programming problem. Java basic syntax and their uses are described briefly so that anyone can easily understand within very short time. If anyone follow the slide with proper way,I assure that he or she will find java programming interesting.
Every value in Java has a data type. Java supports two kinds of data types: primitive data types and reference data types. Primitive data types represent atomic, indivisible values. Java has eight Numeric data types: byte, short, int,
An operator is a symbol that is used to perform some type of computation on its operands. Java contains a rich set of
operators. Operators are categorized as unary, binary, or ternary based on the number of operands they take. They are categorized as arithmetic, relational, logical, etc. based on the operation they perform on their operands.
long, float, double, char, and boolean. Literals of primitive data types are constants. Reference data types represent
references of objects in memory. Java is a statically typed programming language. That is, it checks the data types of all values at compile time.
Java abstract class & abstract methods,Abstract class in java
Abstract classes are classes that contain one or more abstract methods. An abstract method is a method that is declared, but contains no implementation. Abstract classes may not be instantiated, and require subclasses to provide implementations for the abstract methods.
A simple document emphasizing the reasons behind evolution of .Net technology and how it simplified the yester-decade's technology issues. This document is simplified and teaches a lame man as why & how .net framework gained importance and how it is ruling the roost.
Decision Making in Java (if, if-else, switch, break, continue, jump) Decision Making in programming is similar to decision making in real life. A programming language uses control statements to control the flow of execution of program based on certain conditions.

object oriented programming is a key concept for the development of application in windows as well as web based application environment. oops concept maps real world through its concept of classes, objects, inheritance, polymorphism which help in making a robust application.

4. How it works…! Compile-time Environment Compile-time Environment Java Bytecodes move locally or through network Java Source (.java) Java Compiler Java Bytecode (.class ) Runtime System Class Loader Bytecode Verifier Java Class Libraries Operating System Hardware Java Virtual machine Java Interpreter Just in Time Compiler
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"); } } }
50.
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 (); } }
