I am encountering a confusing bug when attempting to print a HTML table with my servlet. The last row is printing 4/8 elements and then stopping. There is no problem with the first 7 rows, which are practically identical to the 8th.
Here is my Java code:
...
out.println("<tr>");
j = 0;
for (int i=56; i<64; i++){
j++;
Integer.toString(j);
out.println("<td ");
if (seats[i].label.equals(label)){
seats[i].booked = true;
seats[i].id = id;
seats[i].phone = phone;
seats[i].address = address;
seats[i].email = email;
}
if (!seats[i].booked){
out.println("bgcolor='#7CFC00'");
}
out.println("><a");
if (!seats[i].booked){
out.println(" href='Booking?label=H"+j+"'");
}
out.println(">H"+j+"</a></td>");
}
out.println("</trr");
And here is the resulting HTML code from my browser:
...
<tr>
<td bgcolor="#7CFC00"><a
href="http://localhost:8080/assignment1/Booking?
label=H1">H1</a></td>
<td bgcolor="#7CFC00"><a
href="http://localhost:8080/assignment1/Booking?
label=H2">H2</a></td>
<td bgcolor="#7CFC00"><a
href="http://localhost:8080/assignment1/Booking?
label=H3">H3</a></td>
<td bgcolor="#7CFC00"><a
href="http://localhost:8080/assignment1/Booking?
label=H4">H4</a></td>
</tr></tbody></table>
The array length of seats is 100 so there is plenty of space even if that were why the elements are not displaying. The loop should execute 8 times and show the remaining four required elements as the previous 7 loops did successfully. Would love some help as I'm honestly stumped and need to get my first servlet assignment done before it's too late.
I think problem is at out.println("</trr");
. Please try to use out.println("</tr");
I have commented below code(because I don't have seating.ser) of your Main.java in my local system:
//Deseriailzing seating
/*try {
FileInputStream fileIn = new FileInputStream("seating.ser");
ObjectInputStream in = new ObjectInputStream(fileIn);
seats = (Seat[]) in.readObject();
in.close();
fileIn.close();
} catch (IOException i) {
i.printStackTrace();
out.println("IOException i");
//return;
} catch (ClassNotFoundException c) {
out.println("Employee class not found");
c.printStackTrace();
//return;
}*/
and
// ObjectOutputStream oos = null;
// FileOutputStream fout = null;
/*try {
FileOutputStream fileOut = new FileOutputStream("seating.ser");
ObjectOutputStream out2 = new ObjectOutputStream(fileOut);
out2.writeObject(seats);
out2.close();
fileOut.close();
System.out.printf("Serialized data is saved in seating.ser");
}catch(IOException i) {
i.printStackTrace();
}*/
then executed. It's working fine.So the Issue is in your seating.ser file or above commented code.
Here is my Seat class(this used in Main.java) code:
public class Seat {
String label,phone,address,email,bookingTime;
String id="";
boolean booked;
}
