Two statements, get results from the first statement?

Question

Ok maybe I made it sound a little harder than it is, but this is what I am trying to do. I have a result set from from a database call when I pass in the username and password . In the 1st call I get the Users info: User_ID, first_name, lastname, etc...
But I either need to get info from the first statement, and pass it to the 2nd statement or just do two statement calls calling the same info and passing it to my user object? I dont know which if any is faster, or better. The only thing I need from the first statement is the user_id. In the 2nd statement I need the user_id to find out the user permissions.
Here is the original code when It was getting the user info and permissions from the same table. try
           dba = new DbAccess();
           java.sql.Connection con = dba.getConnection();          
java.sql.DriverManager.getConnection("jdbc:oracle:thin:@kares:1523:appd","user","pass");  
           ps = con.prepareStatement("SELECT USER_ID, LAST_NAME, FIRST_NAME, LOGIN, PASSWORD," +
           "X, Y, Z FROM RD_USERS WHERE LOGIN=? and PASSWORD=?");
           ps.setString(1, user);
           ps.setString(2, pass);
           rs = ps.executeQuery();
           // set the user attributes
           if ( rs.next() )
              loginValid = true;
              setUserId(rs.getInt("USER_ID"));
              setLastName(rs.getString("LAST_NAME"));
              setFirstName(rs.getString("FIRST_NAME"));
              setLoginName(rs.getString("LOGIN"));
              setPassword(rs.getString("PASSWORD"));   
              X = rs.getBoolean("X");
              setX(X);
              Y = rs.getBoolean("Y");
              setY(Y);
              Z = rs.getBoolean("Z");
              setZ(Z);
           else
              setLastName(null);
              setFirstName(null);
              setLoginName(null);
              setPassword(null);
              setX(false);
              setY(false);
              setZ(false);
           rs.close(); rs = null;
           ps.close(); ps = null;
           //dba.close(); dba = null;
        } The code above gets the info from one table, I now need to get the X, Y, and Z from a different table, but I need the USER_ID first. So, the first table is set up with the user_id and user info, and the 2nd table is set up with the user_id and user permissions

Thanks DrClap I started on the the query and I did it a little differently, but it should hopefull do the same thing. my tables are constructed as so:
USER
     USER_ID
     FIRST_NAME
     LAST_NAME
     USER_NAME
     PASSWORD
     ETC....
USER_PERMISSIONS
     USER_ID
     PERMISSION X
     PERMISSION Y
     PERMISSION Z
     ETC....
My Select looks something like this
ps = con.prepareStatement("SELECT a.USER_ID, a.LAST_NAME, a.FIRST_NAME, a.USER_NAME, a.USER_PASSWORD," +
           "b.X, b.Y, b.Z FROM RD_USERS a, RD_PERMISSIONS b WHERE USER_NAME=? and USER_PASSWORD=?");
This is where I come to a crossroads, Can I add on another AND to say "WHERE a.USER_ID = b.USER_ID
and do I use the =, or is it ==, or .equals(). Thanks in advance.
