So I'm trying to create an unspecified table name with an unspecified columns, however, I'm new to prepareStatement and I'm not exactly sure what to do.
This is how I'm thinking about it
I know I'll need a loop for multiple entries of "line" which is the table name
but how can I deal with the columns? I think I'm specifying the number of columns in here (4). How can I do this without specifying? and what should I put for setString if the value will differ based on the table name?
I'm kind of confused and I was hoping that someone will explain this to me
loop start ....
line = kb.next();
sql = "Create TABLE " + line + "(?,?,?,?)";
pstmt = conn.prepareStatement(sql);
pstmt.setString(1,?);
pstmt.executeUpdate();
loop end

It's unlikely that you'll be able to get this to work on any database.
