Java Programming

Introduction to Java

Introduction to java programming technology, it development environment, anatomy of Java program and Hello world program.

Data types, variable and constant

Discuss data types used in java program. Explains the variable concept and how to use them, and what is constant and how its similar to variable but used in different circumstance.

Input and output

Getting input and producing output in program. Discover libraries used for perform input and output in Java.

Operator

Operators performs mathematical operation to data in a program. Discover different types of operations done and what operators are used to do this operations.

Selection statement

Discover what is a selection statement and how to use them to control java program execution. There are three to five variation of selection statement that can be used in Java program.

Loop

Discover what we can do with a loop statement in Java program. There are three types of loop statement, learn its structure and how to use them here.

Method

Similar to functions, method is java construct used to break down a complex program into smaller more manageable units. In object oriented programming, method is a way to express the behaviour of an object.

Array

Array is a collection of data that of same type. Instead of having many loose variables that has similar purpose, array group these variables in a single group, and access the individual variable called elements using index.

String

String is a type of character array. It is used to express a line of text in a program. Java provides many function used to manipulate string.

Class and Object

Java in Object Oriented Programming language. Class and object is the basic building block in the program structure. Class allows programmer to define their own data types besides the primitive types like int, float, etc.

Inheritance

Inheritance is one of the main concepts of the object oriented programming. It allows programmer to reuse the existing class and expand its capabilities by introducing a new class.

Polymorphism

Polymorphism is one of the main concepts of the object oriented programming. It allows a object to behave differently under different circumstances. Polymorphism can be achieved by implementing method overloading and overriding.

Encapsulation

Encapsulation is another main concept is OOP. It is the process of assembling data and its method as a single unit. Encapsulation is also known as data hiding.

Abstraction

Abstraction probably the important concept of OOP. It is the process of hiding complex ways of handling a problem and only expose necessary information to the user. With abstraction, user can solve complex problem with ease without knowing its inner workings.

Drawing Simple Pie Chart

Image
To draw pie chart with 5 sectors. The program calculates the total of all the input given by user and find the angle in degrees to draw each sectors. When the program first loads, chart based on default values is painted by the program. User can edit the values in the text field and presses draw button to redraw the chart. Each time the draw button is pressed, new set of angle is calculated and repainted. I have attached the the sources for this program. It is simple and needs upgrades. Pie.java This class executed the program and initializes the components JTextField and JPanel to draw the chart. package coolApp.graphics; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Pie { JTextField a,b,c,d,e; JButton btnDraw; double total; JPanel contentPane; Pie(){ JFrame frame = new JFrame("Pie - CoolApps"); frame.setSize(500,500); contentPane = new JPanel(); contentPane.setLayout(new BorderLayout()); frame

VB.net connecting to SQL Server

Connecting to SQL server 2014 from VB.Net 2017, read values from the database and display the data in windows form. Before begin to write this program, first we need to import SqlClient class. Imports System.Data.SqlClient Step 1 Create a sql connection object. This is to make connection to object. Dim conn As New SqlConnection() Step 2 Set the connection string to the sqlconnection object: conn.ConnectionString = connStr Road block The variable connStr is a connection string. Connection object need connection string to make connection to database. It has information like who providing the database, the name of the database and some security information. Dim connStr As String = "Data Source = ServerInstanceName;Initial Catalog=testDB;Integrated Security=True" Let's break down the connection string into the three main components. Dim provider As String = "ServerInstanceName;" Dim database As String = "Initial Catalog=testDB;" Dim

VB.net

a quick and convenient way to build a window based application. basically there is two main components in VB, the design view where we place the controls on a window form. then we have the code view where we write implementation for each controls on the form. Typically the control implementation or procedures are executed when certain events happens to the controls. Events like mouse click, or value change on text box, form load, form close and so on. After working with programming language like C, C++ and Java, getting use to VB is a bit challenging. its because first of all, VB don't use curly bracket to specify code blocks, and the statements don't end with semicolon. variable declaration for example is written as dim age As Integer in C, C++ and Java it written int age; in VB, variable declaration start with dim keyword, it means dimension and the functions are written as Function addNumber(ByVal num1 As Integer, ByVal num2 As Integer) As Integer addNumber
