Java databse connectivity to Oracle DB

How to connect oracle DB through Java

 

You need ojdbc6.jar in your library.

 

import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;

public class OracleJDBC {

public static void main(String[] argv) {

System.out.println("-------- Oracle JDBC Connection Testing ------");

try {

Class.forName("oracle.jdbc.driver.OracleDriver");

} catch (ClassNotFoundException e) {

System.out.println("Where is your Oracle JDBC Driver?");
e.printStackTrace();
return;

}

System.out.println("Oracle JDBC Driver Registered!");

Connection connection = null;

try {

connection = DriverManager.getConnection(
"jdbc:oracle:thin:@localhost:1521:mkyong", "username",
"password");

} catch (SQLException e) {

System.out.println("Connection Failed! Check output console");
e.printStackTrace();
return;

}

if (connection != null) {
System.out.println("You made it, take control your database now!");
} else {
System.out.println("Failed to make connection!");
}
}

}
