if found in first table print the row else go to second table.

rs = st.executeQuery("select * from electricity where accountno='"+acnumber+"'");
if(rs != null){              // If find it print("you paid")  If not go next step
out.println("you paid"+ rs);



}else if(rs == null) {      // here must print ("you must paying bill")
rs = st.executeQuery("select * from paying where accountno='"+acnumber+"'");
out.println(" you must pay  ");
}
