JDBC连接问题

bg999

初学问个菜鸟问题,我代码如下:
import java.sql.*;

public class TestJDBC {

    public static void main(String[] args) throws Exception {
            Class.forName("oracle.jdbc.driver.OracleDriver";
            String url = "jdbcracle:thin192.168.1.120:1521rcl";
            Connection conn = DriverManager.getConnection(url,"scott","root";
        Statement stmt = conn.createStatement();
        ResultSet rs = stmt.executeQuery("select * from dept";
        while(rs.next()){
        System.out.print("DeptNo: " + rs.getInt(1));
                System.out.print("\tDeptName: " + rs.getString(2));
                System.out.println("\tLOC: " + rs.getString(3));                                                    
        }
        rs.close();
        stmt.close();
        conn.close();
    }
   
   
}

执行后抛出异常,我找不到原因哪位高手帮忙看一下:
Exception in thread "main" java.sql.SQLException: Io 异常: The Network Adapter could not establish the connection

连不上数据库，检查是否写错了IP地址或者断口号或者SID
