The Java Database Connectivity (JDBC) API is the industry standard for database-independent connectivity between the Java programming language and a wide range of databases – SQL databases and other tabular data sources, such as spreadsheets or flat files. The JDBC API provides a call-level API for SQL-based database access.
JDBC technology allows you to use the Java programming language to exploit "Write Once, Run Anywhere" capabilities for applications that require access to enterprise data. With a JDBC technology-enabled driver, you can connect all corporate data even in a heterogeneous environment.

Di bawah ini beberapa syntax sederhana pada pemrograman Java
1 ) Syntax sederhana pada Java
class HelloWorld
{
public static void main(String[] args)
{
System.out.println("Hello World !");
}
}
2) Syntax yang digunakan untuk menngunakan output pada panel
import javax.swing.*;
public class HelloGUI
{
public static void main(String[] args)
{
JOptionPane.showMessageDialog(null,"Hello World!!!");
System.exit(0);
}
}
3) Program Sederhana Yang meminta inputan User dengan memunculkan panel jika user memasukan suatu angka.
import javax.swing.JOptionPane;
public class DialogApp
{
public static void main(String[]args)
{
String s;
s=JOptionPane.showInputDialog("Enter An Integer: ");
int x =Integer.parseInt(s);
System.out.println("you entered " + x + ".");
}
}
4) Syntax For
public class CaseApp
{
public static void main (String [] args)
{
for(int i = 0 ; i<5>
System.out.println("Rendy");
}
}
5) Syntax While
public class Counter
{
public static void main (String [] args)
{
int angka = 2;
while (angka <=20)
{
System.out.print(angka + " ");
angka += 2;
}
System.out.println();
}
}
6)Looping Forever
public class CounterFor
{
public static void main (String [] args)
{
int angka = 2;
while (true)
{
System.out.print(angka + " ");
angka += 2;
}
}
}
7)Syntax DoWhile
public class CounterDoWh
{
public static void main (String [] args)
{
int angka = 2;
do
{
System.out.print(angka + " ");
angka += 2;
}while (angka <=20);
System.out.println();
}
}
8) Mendeklarasikan Class dan Variable
public class HelloApp
{
static String helloMessage;
public static void main (String [] args)
{
helloMessage = "Hello, World !";
System.out.println(helloMessage);
}
}
9) Penggunaan Fungsi Matematika
public class MathApp
{
public static void main (String [] args)
{
int a = 100;
int b = -50;
int c = 3;
double x = 25.0;
double y = 3.0;
double z = 4.0;
System.out.println("abs(b) = " + Math.abs(b));
System.out.println("cbrt(x) = " + Math.cbrt(x));
System.out.println("exp(y) = " + Math.exp(z));
System.out.println("hypot(y,z) = " + Math.hypot(y,z));
System.out.println("log(y) = " + Math.log(y));
System.out.println("log10(y) = " + Math.log10(y));
System.out.println("max(a, b) = " + Math.max(a, b));
System.out.println("min(a, b) = " + Math.min(a, b));
System.out.println("pow(a, b) = " + Math.pow(a, c));
System.out.println("random() = " + Math.random());
System.out.println("signum(b) = " + Math.signum(b));
System.out.println("sqrt(x) = " + Math.sqrt(y));
}
}
10) Random
public class DiceApp
{
public static void main (String [] args)
{
int roll;
String msg = "100 angka random dadu";
System.out.println(msg);
for(int i=0;i<100;i++)
{
roll=randomInt(1,6);
System.out.println(roll + " ");
}
System.out.println();
}
public static int randomInt(int low, int high)
{
int result = (int) (Math.random() * (high - low +1)) + low;
return result;
}
}
11) Implementasi public dan private TickTock
import java.awt.event.*;
import javax.swing.*;
public class TickTock
{
public static void main (String [] args)
{
Timer t= new Timer (1000, new Ticker());
t.start();
JOptionPane.showMessageDialog(null, "Click Ok Untuk keluar dari program");
}
}
class Ticker implements ActionListener
{
private boolean tick = true;
public void actionPerformed(ActionEvent event)
{
if(tick)
{
System.out.println("Tick...");
}
else
{
System.out.println("Tock...");
}
tick=!tick;
}
}

Pertanyaan yang muncul sekarang adalah adakah sebuah sistem yang dapat mengakomodasi perkembangan informasi yang sangat cepat ini dan yang dapat memberikan keuntungan kepada pihak yang menggunakannya? Jawabannya tentu saja ada, yaitu dengan menerapkan Content Management System (CMS).
Dalam tulisan ini, penulis akan berusaha menjelaskan kepada pembaca apa yang dimaksud dengan CMS, keuntungan pemanfaatan CMS dan bagaimana cara memilih CMS yang baik. Dengan harapan setelah membaca tulisan ini, pembaca memperoleh gambaran yang jelas tentang CMS atau bahkan dapat menerapkan CMS di website-nya masing-masing.
