Java Programming

pcb — Tue, 20 Mar 2007 14:55:27 +0800

My lecturer give me an assignment, the question is:

A quantity known as the body mass index (BMI) is used to calculate the risk of the weight-related health problems. BMI is computed by the formula

BMI = w/(h/100.0) power of two

where w is height in kilograms and h is height in centimeters. A BMI of about 20 to 25 is considered "normal". Write an application that accepts weight and height (both integers) and outputs the BMI. use System.in for input and System.out for output.

the question is simple, but my lecturer want the program have a three element, correctness, robustness and flexibility.

i have no problems with correctness and flexibility, but i have a problem with robustness, which is i don't know how to validate user input. refer to the question above, w and h need to be input in integer data type, how about user input string or double data type? how to validate it? how the codes?

really2 appreciate for your reply

thanks in advance

$id_species = $_POST["ID_Species"];

print $id_species;

PHP/Mysql .. Array and looping .. help me please!

pcb — Thu, 07 Sep 2006 12:58:36 +0800

Help me... i have a problem in POST an array... the code is :

<?php
function updatecommon($id_species)
{
?>
<form action="CommonProcess.php" method="post">
<td><div align="center" class="style1">BELOW ARE/IS THE EXISTING DATA
<?
$result1 = mysql_query("SELECT * FROM `BIODIVERSITY`.`common_name` WHERE `ID_Species` = '$id_species' ");
while($getData=mysql_fetch_array($result1))
{
$common = $getData["Common"];
print (" $common, \n");
}
print("<BR>");
?>
<td height="71"><div align="center" class="style1">PLEASE ENTER THE NEW DATA IN THE SPACE BELOW </div></td>
<?
$i = 0;
$result2 = mysql_query("SELECT * FROM `BIODIVERSITY`.`common_name` WHERE `ID_Species` = '$id_species' ");
while($getData=mysql_fetch_array($result2))
{
$common = $getData["Common"];

?>
<? echo '<input type="text" name="NewCommon['.i.']" size="30" />';
$i++;
}
print("<BR>");

?>
<td height="99"><div align="center">
<input type = "hidden" name = "ID_Species" value="<? echo $id_species ?>">
<input type="submit" name="updateCommon" value="Update Common">
</body>
</form>
<?
}
?>

$result1 is to retrieve data.. to show existing data.. result2 is to provide a textbox equal to the number of existing data.. so.. in the result2 the syntax :: echo '<input type="text" name="NewCommon['.i.']" size="30" />';
$i++; :: is it true NewCommon['.i.'] is a syntax of array... then.. after user click updateCommon button .. all the data will post to the CommonProcess.php

CommonProcess.php the code is ::

<?php
$ArrCommon[] = $_POST["NewCommon"];
$id_species = $HTTP_POST_VARS["ID_Species"];

foreach ($ArrCommon as $value)
{
$query = "UPDATE `BIODIVERSITY`.`common_name` SET `Common` = '$value' WHERE `ID_Species` = '$id_species'";
mysql_query($query);
}
?>

so.. i dont know how to declare an array is true $ArrCommon[] = $_POST["NewCommon"]; is the syntax?? help me please..

thanks for advance
