JDBC driver for SQLite. It comes in two flavours, a 100% Pure Java driver based on NestedVM or a native JNI library. The pure java driver is compatible, you can follow the Java dream and use it anywhere with no worries. The native driver is fast, and I recommend it wherever possible. Binaries are provided for Windows and Mac OS X.

import java.sql.*;
 
public class Test {
    public static void main(String[] args) throws Exception {
        Class.forName("org.sqlite.JDBC");
        Connection conn = DriverManager.getConnection("jdbc:sqlite:test.db");
        Statement stat = conn.createStatement();
        stat.executeUpdate("drop table if exists people;");
        stat.executeUpdate("create table people (name, occupation);");
        PreparedStatement prep = conn.prepareStatement(
            "insert into people values (?, ?);");
 
        prep.setString(1, "Gandhi");
        prep.setString(2, "politics");
        prep.addBatch();
        prep.setString(1, "Turing");
        prep.setString(2, "computers");
        prep.addBatch();
        prep.setString(1, "Wittgenstein");
        prep.setString(2, "smartypants");
        prep.addBatch();
 
        conn.setAutoCommit(false);
        prep.executeBatch();
        conn.setAutoCommit(true);
 
        ResultSet rs = stat.executeQuery("select * from people;");
        while (rs.next()) {
            System.out.println("name = " + rs.getString("name"));
            System.out.println("job = " + rs.getString("occupation"));
        }
        rs.close();
        conn.close();
    }
} 

Run with:

java -cp .:sqlitejdbc-v044-native.jar -Djava.library.path=. Test

PHP is gaining positive reputation for its system administration and client-side application development capabilities. This administration and development is accomplished using the PHP-GTK extension. You can take advantage of client-side applications by implementing language bindings for the GTK (the GIMP Toolkit) library for creating cross-platform graphical user interfaces.
Pro PHP-GTK acts as both a definitive reference and a hands-on tutorial to the PHP-GTK extension.

In just a few years PHP has rapidly evolved from a small niche language to a powerful web development tool. Now in use on over 14 million Web sites, PHP is more stable and extensible than ever. However, there is no documentation on how to extend PHP; developers seeking to build PHP extensions and increase the performance and functionality of their PHP applications are left to word of mouth and muddling through PHP internals without systematic, helpful guidance.

As a PHP developer, you have some great tools for developing web applications. Ruby on Rails is another key tool to add to your web development toolbox. Rails is a high-level web development framework that emphasizes high productivity and clean code. However, the Ruby language and Rails framework take a different approach from the way many PHP developers write applications.

Do while loop executes group of Java statements as long as the boolean condition evaluates to true.

It is possible that the statement block associated with While loop never get executed because While loop tests the boolean condition before executing the block of statements associated with it.

In Java programming, sometime it's necessary to execute the block of statements at least once before evaluating the boolean condition. Do while loop is similar to the While loop, but it evaluates the boolean condition after executing the block of the statement.

Do While loop syntax

Do{

<Block of statements>;

}while();

Block of statements is any valid Java code. Boolean condition is any valid Java expression that evaluates to boolean value. Braces are options if there is only one statement to be executed.

Break statement is one of the several control statements Java provide to control the flow of the program. As the name says, Break Statement is generally used to break the loop of switch statement.

Please note that Java does not provide Go To statement like other programming languages e.g. C, C++.

Break statement has two forms labeled and unlabeled.

In this article I want to show you to write a simple hello world example using Java & NetBeans IDE 6.

One question that a lot of beginning programmers have is: "Now that I've created my application in the IDE, how do I get it to work from the command line outside of the IDE." Similarly, someone might ask, "How do I distribute this application to other users without having to give them the whole IDE as well?"

The answers to these questions are relatively simple, but not necessarily obvious. This document addresses those questions by taking you through the basics of using NetBeans IDE 5.0 to prepare your applications for distribution and then deploying those applications. In addition, this document provides information that you might need to configure your system (or which you might need to pass on to the users of your application). We will show a few different approaches for deploying an application, so that users can access the application by:

• Double-clicking the application's Java Archive (JAR) file.
• Calling the application from the command line.
• Calling the application from a script file.

Along the way, we will cover some basics of JAR file structure and how JAR files are dealt with inside IDE projects.

Many times when we get a chance to work on a small project, one thing we intend to do is to put all java files into one single directory. It is quick, easy and harmless. However if our small project gets bigger, and the number of files is increasing, putting all these files into the same directory would be a nightmare for us. In java we can avoid this sort of problem by using Packages.
