Hi,

I tried at my end with the below code and it is working fine.
List<Boook__c> bookList = new List<Boook__c>();
Boook__c b = new Boook__c(Name = 'Test', Prise__c = 100);
bookList.add(b);
MyHelloWorld.applyDiscount(bookList);
System.debug('CHECK:'+bookList);
In Debug, you will get the prise value as 90.
If you still get the error try with firefox or Google Crome browser.

Hi,
What error you are getting?
First you should create a "Boook" object with  "Prise__c" field in salesforce.
After that write a tigger on that object, only then it will work.

Check the below link for more informatiom.

Hi,

I created already and what my trigger is


trigger HelloWorldTrigger on Boook__c (before insert) 
{    
Boook__c[] books = Trigger.new;    
MyHelloWorld.applyDiscount(books);
}

this trigger is right r wrong?
please let me know.


 
Anoop yadavAnoop yadav
Yes, this is correct.
What error you are getting?
are you putting any value in "Prise__c" field before inserting the record?
Keer YenduriKeer Yenduri

Hi,

i am getting dis err

"
Method does not exist or incorrect signature: MyHelloWorld.applyDiscount()
"


 
Anoop yadavAnoop yadav
How you are calling this method?
Keer YenduriKeer Yenduri
Hi,
MyHelloWorld.applyDiscount();

in developer consle.
Anoop yadavAnoop yadav
You Should create a tab for Boook object.
and when you insert the boook record it will call that method.

If you want to execute from developer console Use the below code.
List<Boook__c> bookList = new List<Boook__c>();
Boook__c b = new Boook__c(Name = 'Test', Prise__c = 100);
bookList.add(b);
MyHelloWorld.applyDiscount(bookList);

What you want to do?
and what result you are expecting?
Keer YenduriKeer Yenduri
Hi,
Anoop first i want to execute the class den i will k with my class.
if it is executed den i will think that class is correct.
So i want to execute that class
see
first i created the custom object and custom fields for that
next i wrote trigger and class,
in my way of thinking if class works proprly den my work is done
 
Anoop yadavAnoop yadav
To check the above class you should follow some more steps.

Create a tab for the above object by SetUp==>Tabs
click on new in "Custom Object Tabs", select the object and save.
After that you will get a Boook tab in tab panel.
Click on the tab, create new record, enter the name and price
after saving the record price value will be multiplied by 0.9.
Let me know if you neeed more help.
 
Keer YenduriKeer Yenduri

Anoop yadavAnoop yadav
The above one is not an error.
Can you run that again and let me know.

or run the below code
Boook__c[] bookList = new Boook__c[];
Boook__c b = new Boook__c(Name = 'Test', Prise__c = 100);
bookList.add(b);
MyHelloWorld.applyDiscount(bookList);


 
Keer YenduriKeer Yenduri
Hi,
Again i tried,
But
i got this error
ERROR:in developer console
expecting left curly bracket, found ';'
with this code when i am executing

Boook__c[] bookList = new Boook__c[];
Boook__c b = new Boook__c(Name = 'Test',Prise__c = 100);
bookList.add(b);
MyHelloWorld.applyDiscount(bookList);

And  i am saying u
what are my components are:

1)
Objectname:Boook   APIname:Boook__c
Fieldname:Prise     APIname:Prise__c


2)
trigger HelloWorldTrigger on Boook__c (before insert)
{
Boook__c[] books = Trigger.new;
 MyHelloWorld.applyDiscount(books);
}

3)
public class MyHelloWorld
{
public static void applyDiscount(Boook__c[] books)
{
for(Boook__c b:books)
{
b.Prise__c*=0.9;
}
}
}

4)
DeveloperConsole:
Boook__c[] bookList = new Boook__c[];
Boook__c b = new Boook__c(Name = 'Test',Prise__c = 100);
bookList.add(b);
MyHelloWorld.applyDiscount(bookList);

Please let me know the solution for that.

Thanks!!!!
