How do I enter selected data from one table to another table in DAO class?

public boolean registerCustomer(CustomerBean obj) 
{
String sql1;
PreparedStatement ps = null;
try {
sql1 = "INSERT into Registration values(?,?,?,?)";//registration is working Fine
ps = conn.prepareStatement(sql1);
ps.setString(1, obj.getName());
ps.setString(2, obj.getEmailId());
ps.setString(3, obj.getPassword());
ps.setString(4, obj.getCountry());
int ret = ps.executeUpdate();//here I want to send Email id and Password to another table 


if(ret > 0) {
conn.commit();
return true;
}

//update line

sql1 = "INSERT into AnotherRegistration values(?,?)";//registration is working Fine
ps = conn.prepareStatement(sql1);
ps.setString(2, obj.getEmailId());
ps.setString(3, obj.getPassword());

int ret = ps.executeUpdate();

if(ret > 0) {
conn.commit();
return true;
}
} catch(SQLException sqe) {
sqe.printStackTrace();
}
return false;
}
