Java连接Oracle

1.odbc方式

2.jdbc驱动包方式

public static void main(String[] args) {
    try {
        //Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        Class.forName("oracle.jdbc.driver.OracleDriver");
        //Connection con=DriverManager.getConnection("jdbc:odbc:scott", "scott", "123456");
        Connection con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl", "scott", "123456");
       
        Statement stmt=con.createStatement();
        ResultSet rs=stmt.executeQuery("select * from emp");
        while (rs.next()) {
            System.out.println(rs.getString(2));
        }

            rs.close();
            stmt.close();
            con.close();

        
    } catch (Exception e) {
        e.printStackTrace();
    }
}
