Java中如何使用JDBC连接Oracle数据库呢？

实现思路:
    借助oracle.jdbc.driver.OracleDriver包
	即可实现JDBC连接Oracle数据库

package com.java265.other
public class OracleJdbcTest 
{ 
  String driverClass = "oracle.jdbc.driver.OracleDriver"; 
 
  Connection con; 
 
  public void init(FileInputStream fs) 
  throws ClassNotFoundException, SQLException, FileNotFoundException, IOException 
  { 
    Properties props = new Properties(); 
    props.load(fs); 

	//配置数据库连接参数
    String url = props.getProperty("db.url"); 
    String userName = props.getProperty("db.user"); 
    String password = props.getProperty("db.password"); 
    Class.forName(driverClass); 
 
    con=DriverManager.getConnection(url, userName, password); 
  } 
 
  public void fetch() throws SQLException, IOException 
  { 
    PreparedStatement ps = con.prepareStatement("select SYSDATE from dual"); 
    ResultSet rs = ps.executeQuery(); 
 
    while (rs.next()) 
    { 
      //获取数据
    } 
    rs.close(); 
    ps.close(); 
  } 
  
  public static void main(String[] args) 
  { 
    OracleJdbcTest test = new OracleJdbcTest(); 
    test.init(); 
    test.fetch(); 
  } 
}
