How to use prepared statements with a single id

Question

Here is the code I am having trouble with:
String sqlb = "INSERT INTO books.book(title)" +
                         "VALUES(?)";
               String sqla = "INSERT INTO books.author(name,date_of_birth)" +
                         "VALUES(?,?)";
               PreparedStatement psb = c.prepareStatement(sqlb);
               PreparedStatement psa = c.prepareStatement(sqla);
               psb.setString(1,book.getTitle());
               psa.setString(1,author.getName());
               psa.setString(2,author.getDate());
               m = psb.executeUpdate();
               n = psa.executeUpdate();
After placing two book/Author objects into the database I get a table that looks something like this:
0 AGreatBook Joe Bloggs 08-10-83
1 BGreatBook Joe Bloggs 08-10-83
2 AGreatBook John Smith 12-12-65
3 BGreatBook JohnSmith 12-12-65
Clearly this is not correct I want this:
0 AGreatBook Joe Bloggs 08-10-83
1 BGreatBook John Smith 12-12-65
By the way I have placed a foreign key in book table
Anyone know how to do this? (I am using postgres)
regards
