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

String url="jdbc:oracle:thin:@127.0.0.1:1521:xe";

String user = "scott";

String password="tiger";

Connection conn = DriverManager.getConnection(url,user,password);

PreparedStatement pstam = conn.prepareStatement("select * from userinfo ");

ResultSet rs = pstam.executeQuery();

while(rs.next()){

System.out.println(rs.getInt("id")+rs.getString("name")+rs.getInt("age"));

}

pstam.close();

conn.close();
