源代码：import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class OrclaeConnectionDemo {
public static final String DBDRIVER="oracle.jdbc.driver.OrcaleDriver";
public static final String DBURL="jdbc:oracle:thin:@localhost:1521:ORCL";
public static final String DBUSER="scott";
public static final String DBPWD="tiger";

private static Connection conn=null;

public static void main(String[] args) {
try {
Class.forName(DBDRIVER);
conn = DriverManager.getConnection(DBURL, DBUSER, DBPWD);
if(conn!=null){
System.out.println("连接成功！");
}else{
System.out.println("连接失败！");
}
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally{
try {
conn.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}

}
